Let’s Talk Nurses!

Timing is everything! 

Miss America was on TV a couple weeks ago, and I actually happened to catch a little of it while catching up on my most frequent chore – folding laundry! 

If I remember correctly, I hoped Miss Tennessee would win because she was a vocal STEM advocate, in addition to being stunning (all of the women were).

It wouldn’t be Miss America though, if there weren’t controversy. This year did not disappoint! Within a couple days, there was scandal over the comments on The View about Miss Colorado and her speech about being a nurse. 

Timing is everything.

The comments ended up being especially poignant to me because I coincidentally had a series of fantastic experiences with incredible nurses and other health care professionals last week.

You see, my best little girlfriend broke her arm. In two places, I came to find out.

Trying to get a little sleep after a very long night in the ER

She’s a tough cookie, which made it hard for us to tell if we should take her to the emergency room right away or not. I finally decided we needed to get it checked out when she cried in her sleep. 

Not much is open at 11:30 at night, and I have no patience for waiting when my baby is hurting, so we made a “quick” trip to the emergency room. 

Spending the night (or just part of the night) in the ER is miserable – seriously! But, we were cared for by a great team. Everyone we met from the security guard to the to the doctors, to the radiology techs, nurses, and PCAs were fantastic. There were thoughtful, kind, and patient with my over-tired, hurting toddler. And – they knew their stuff! 

We went back to the doctor for another appointment a couple days later to get a hard cast put on. We talked to the doctor for just a couple minutes (he was wonderful!), then another woman (a nurse or a PA?) was the person to actually put on the cast.   

Action shot! a broken n arm won’t hold this girl up! She was playing hard at a bounce house party 2 days after the cast went on.

Never having broken a bone, I was surprised the doctor didn’t do the cast himself – but it makes sense! If the doctor takes the time to put on all the casts, it limits the number of patients that can be seen.

Since I was experiencing healthcare first hand, and listening to the news about the role of nurses in healthcare, it made me think about my most pivotal healthcare moment – again, one that was shared with my sweet little STEMinista.

When I was pregnant with her, I had a serious condition called placenta previa. I’ll spare you the details, but it was serious enough that I spent three weeks on bed rest (2 of those in the hospital) before she was born.

And she was STILL six weeks early!

She was so early, and so small and sleepy, that she spent 19 days in the neonatal intensive care unit.

If you want to learn about the role of nurses and the impact they have in peoples’ lives, try spending some major time in a hospital.

As Miss Colorado discussed in her monologue, the nurses were the first people I talked to every day, and the last people I spoke to at night. For me, they did everything from giving IVs, to administering medicine, to monitoring my vitals,keeping me calm when I went into premature labor, and even making a ribbon bow to pin on my Halloween baby skeleton shirt. They knew their science and their medicine, and they showed compassion and love as well.

Our experience in the NICU was even more remarkable. The doctor popped in twice a day to check on the kids, but the nurses were literally with the babies 24 hours a day, 7 days a week. 

Teenage girls get a reputation for being high maintenance, but NICU babies are SERIOUSLY high maintenance. They need diaper changes, baths, and weigh-ins, they need to eat every 2-3 hours (often through feeding tubes), they’re hooked up to all sorts of tubes and monitoring wires, and sometimes they forget to breathe on their own.

Yes, you read that last part correctly. They sometimes

One of the most unnerving parts of the NICU to me was that there were babies whose breathing monitors went off almost every time we visited. An alarm would sound, and if it didn’t go off after a few seconds, a nurse would literally go over to the baby, and wake him/her up as a reminder to breathe. It was terrifying the first time I saw it, the last time I saw it, and every time in between. These little ones literally rely on the care of nurses to do something as simple as breathe.

On top of all that, the nurses deal with over-hormonal, over-tired, stressed out parents, while implementing doctors’ orders and caring for their little patients. Bless their hearts. It’s an incredibly hard job. One that I don’t know if I would have the stomach or the heart for.

So, from the bottom of my heart, I want to thank all of the nurses (and other health care professionals) out there for the hard work you do – but especially the nurses. You’ve made a dramatic impact in my life, and I am so grateful for each and every one of you, whether you’re using a ‘doctor stethoscope’, a ‘nurse stethoscope’, a ‘PA stethoscope’, or any other stethoscope. 


STEM: Create Your Own Career Path

CareerPathIt’s been a busy couple of weeks at my house. It’s hard to say for sure, but I think the biggest thing going on at home has been that my son started kindergarten last week (does that make me old?!?), and my daughter started at a new preschool. As such, there has been much discussion at home about how grown up STEMboy is, and what he thinks the future holds.

If you ask him what he wants to be, his answer alternates almost daily, between:

  1. Paleontologist
  2. Artist

Obviously, LOL. Two professions I would never compare with each other – but the boy loves art projects, and the boy loves dinosaurs. For awhile, his favorite show was Dinosaur Train.

We were driving to visit a relative the other day, and STEMboy wanted to play a guessing game (a common occurrence in our family).

STEMboy: “Mom, I’m thinking of an island. Guess which one!”

Me: “uhhhhhh…..Mackinac Island?”

STEMboy: “No”

Me: “Hawaii?”

STEMboy: “No”

Me: “Seriously?!? I have to guess any island in the whole world? I need a hint.”

STEMboy: “It’s really old.”

Me: (jaw drops to the floor. I know immediately what he’s thinking, but can’t believe he knows what he’s thinking) “Uhhhhh….Pangea?”

STEMboy: “YES!!! That’s it!!! How did you know that, mom?!?”

Me: (over my husband’s laughter) “I’m a scientist, STEMboy. How do YOU know that?!? Do you know what Pangea is?”

STEMboy: “Of course mom – It’s the island that all the land used to be in a long time ago. It was on Dinosaur Train”

Which of course led to the discussion of how continents shifted, and why that’s relevant to finding dinosaur bones.

Ahhh……moments like this send my heart aflutter. I love seeing my four year old independently learning about science (even if it is from TV), and sharing his love of science with us and others. If he grows up to be a paleontologist, I already know that he will genuinely love his job. If he grows up to be an artist, I’m sure he’ll love that too and of course I’ll support him in that endeavor as well. I can’t wait to see what he will become, but as a parent, my biggest concern is that whatever he does make him happy.

Aside from dinosaurs, is there a STEM-related message in here?

Wait for it….

Wait for it….

It’s coming – but another story first….For now, just remember that STEMboy changes his mind daily about what he wants to be when he grows up.


Another reason for all the recent commotion in my house is that my husband, Mr.SciGuy left his job in automotive engineering back in the spring to pursue a new career. The summer has been full of licensing exams, training trips, and adjusting to a completely different schedule for SciGuy.

So what led to the change, and why?

If you haven’t already read all my previous posts, automotive engineering is a very lucrative career. It has great pay, good benefits, and job stability.


It’s also a very high-stress job. The timelines are tight, and a single mistake can cost thousands, millions, or even billions of dollars. SciGuy was in a job where every day, he had to call and yell at people, make threats, and try to fix emergencies he didn’t cause.

Ugh – can you imagine? It’s an important job, but it wears on you.

Over time, SciGuy came to realize that this wasn’t the job he wanted to do the rest of his life. He wanted to be having positive interactions with people every day. He wanted to make peoples’ days better, not worse, and he wanted to make a difference in the community where we live.

After a lot (seriously, a LOT) of research, thinking, and planning, he decided to pursue a dream that’s been rolling around in his head for over a decade. SciGuy submitted his resignation to his high-paying automotive job to pursue a new career in financial advising at Edward Jones.

A lot of family and friends seemed to be completely baffled by the change at first, but it makes perfect sense to me.

SciGuy has always loved money and money management (if you know him, ask about his famous amortization Excel worksheets or the cost of money over time), working with people one-on-one, and helping others.

As a kid, one of his nicknames was “Alex P Keaton”. (If you are young and missed the magic of 1980’s television, I’m sorry for your loss).

Lastly, he has an incredibly strong math and research background thanks to his engineering degree (foreshadowing: can you see where we’re going here??). While he had no direct experience working in finance, the transition so far has been incredibly smooth because he understands that math, and has a lot of experience in learning to learn challenging concepts.


So how does this apply to you?


If you think you know what you want to do for the rest of your life, but aren’t 110% sure, the versatility of a STEM degree can ensure your success, whether you stay in your planned career path, or not. A STEM degree gives you so many options and so many resources. You can go anywhere, and you can do anything.

Even if you decide ten years into your career that you want to do something completely different than what you’ve always done, a STEM background can make the transition simple and quick (and now I can say for sure to trust me and SciGuy on that!).

That’s HUGE – I can’t emphasize enough how important it is. A lot can change over the course of a decade or even over the time it takes to get your degree. As you gain more educational experience, work experience, and life experience, you’ll better appreciate what you want, what you don’t want, and what really makes you happy. In the big picture, being happy is what matters.

You can find a career that works perfectly for you, or you can write your own job description. Having a job that you find fulfilling will make waking up and going to work every day tolerable – even fun! With a STEM education, you can do anything, chase any dream, and create your own path in life!

Where do you think your path will take you?


Am I really going to need this when I grow up?

Grow UpFor some of you, the first day of school has already arrived, while others are going back in the next week or two. As you get back into the routine of waking up early, going to class, and (ugh!) homework, you may be thinking about the meaning and importance of everything you’re doing.

When you grow up, will you ever need to figure out how much force is needed to push a car up a hill if the coefficient of friction is 0.8? Will you need to know the 12 cranial nerves and what they do, or how to titrate an unknown acid, or how to use calculus to find the volume of a solid object?


Maybe not.

I use a lot more STEM skills in my job than I ever expected to as a student, but I’m also a scientist for a living. Even still, I would never consider doing many things I learned as a student by hand.

Doing math the old-school way

Doing math the old-school way

If I need to calculate an integral, I can do it on a computer. If I need to check an anatomy concept, I can look it up in a book, and if I want to move a car up a hill, I generally either step on the gas if the car is running, or call a tow truck if it’s not (right? You know what I’m saying here!). If I needed to titrate an unknown acid, I suppose I would have to do that by hand, but honestly, how often does one come across unknown acids?

Doing math the new-school way

Doing math the new-school way

I know if you’re a student, you totally feel me on that, but let’s take a step back and look at the overall principal instead.

Part of the importance of school work is to make sure you understand the underlying big concepts. You don’t necessarily need to do the math or the science every time, but once you have done the work yourself once or twice, there’s a lot better chance that you comprehend the basic theory behind the concept.

That way, when we know it’s easier to push something up a slippery hill than a rough hill, and that a cube has a bigger volume than a sphere of the same width, and that adding a base to a solid makes it more neutral, we can explain at least a little bit of the ‘why’ that goes along with the answer.

In STEM, there’s even a little bit more to school and learning than just the big concepts.

Part of school is learning HOW to learn.

Chances are, you’ll go into your first job (and second job, and third job, and so on), and you’ll need to learn a lot of things they never taught you in school. If you’re a student, trust me on this. If you’re a professional, I know you’re nodding your head in agreement.

For instance, if you move to Detroit and work for one of the big 3 automakers (that’s GM, Ford or Fiat-Chrysler for you out-of-towners), you might start out working on transmissions. You’ll need to learn about gear ratios, material properties of metal, linkages, and how to assemble all the parts. No college degree program will teach you all the intricacies of the job without you getting some hands-on experience. But don’t worry – if you have a STEM degree, you’re used to working hard, studying, and using your analytical thinking skills to solve problems.

If you work really hard, and become a walking encyclopedia of transmissions, you might get a promotion to managing a team that does exhaust design. In exhausts, there are a million new things to learn. You need to understand the chemistry of volatile gases coming out of the engine, how they combust, and how the exhaust system removes the chemicals so the car isn’t polluting the air. Plus, another function of exhausts is to quiet the sound of the engine, so you’ll need to learn some basic acoustic concepts as well. By now, you’re probably also doing a little bit of work of planning the production in a remote factory, and trying to optimize the costs as well. And you’re managing a team as well. Good thing you did lots of team work in your STEM education!

Go you - lead that team!

Go you – lead that team!

Luckily, if you have a STEM degree, you’ll have a basic understanding of many of the foundational principals you’ll need to use in the job, and by now, you have YEARS of experience at quickly learning new material. Your STEM background makes you pretty much the best employee ever (but we knew that would happen anyway, right?!?).

Do you see where I’m going with this?

The details of all the work you’re doing may be tedious, and we each have an area (or two) that we find to be even more tedious or more challenging than the rest of the curriculum. But, all that hard work does have a purpose.

Doing all that work in detail ensures you understand the fundamentals of “why”, and it teaches you how to learn. So, grab a water or a coffee, sit down at your desk, and get to work. Do those integrals. Memorize your flash cards, and look forward to those lab experiments. Read your textbooks, and ask lots of questions. Put your heart and soul into learning the fundamentals, and learning how to learn, and you’ll be giving yourself the best possible foundation for a successful career.

Have a great school year!


STEM News: Ice Cream


Ice cream is an integral part of my life, especially in the summer time. It’s practically it’s own food group – there’s protein, grains, fruits/veggies, and ice cream.


I eat it more than I should, but not as much as I want. Sometimes, in an effort to be a little more healthy, I substitute Greek yogurt for ice cream. It’s almost as good (or so I tell myself), and a bit more healthy.

So I was talking about that on Twitter the other night (ice cream is THAT important in my life!), and it was brought to my attention that some areas of the United States are experiencing an ice cream shortage due to a recall. I vaguely remembered hearing about a recall a while back, but had no idea it was still affecting ice cream consumers. Sounds horrible!!

Being the ice cream connoisseur I am, I thought this would be the perfect news story for us to talk about from a STEM angle.

Here’s a great infographic from the CDC that describes the outbreak. Check it out. People got sick from a type of bacteria called Listeria that was found in Blue Bell ice cream.

Want to know what floors me the most?

Only 10 people in the entire United States (1 in Arizona, 5 in Kansas, 1 in Oklahoma, and 3 in Texas) were confirmed to be hospitalized over a period of five years, but that was enough for the Centers for Disease Control (CDC) to isolate the source of the contamination.

That’s incredible!

Think about how many people get sick across the country every day, every year, or every 5 years. To keep track of all those sicknesses and identify a trend from just 10 people blows my mind. Of course, there may have been more cases that weren’t linked, but still, that’s incredible!

Researchers who find these kinds of medical trends are called epidemiologists. Want to know how they found the problem in this case?

Scientists used genetic testing to look at the entire DNA sequence of the listeria of the people who were sick, and compared it to the entire DNA sequence of bacteria found in different Blue Bell ice cream samples. Most of the cases in this outbreak were actually linked to ice cream that people ate while already in the hospital. Talk about horrible luck!

The Blue Bell production sites had been inspected by the Food and Drug Administration (FDA) during the period that contaminated ice cream was being produced, but Listeria was not found during the inspection. There were other health violations, but I assume most factories have minor violations in routine inspections. I don’t know how major or minor the violations were in this case.

I’m certainly not an expert, but it seems like Blue Bell took the right steps throughout the investigation of the outbreak by voluntarily recalling different products as soon as they were linked to the outbreak. Eventually, they ended up shutting down their manufacturing facilities completely, leading to a major ice cream shortage in areas of the south. I feel for you, my friends, especially now that we’re in the thick of the summer heat!

Since genetically different version of Listeria were found in the different manufacturing facilities, and Listeria was not found during the routine FDA inspections, I’m not sure what the actual source of the contamination was, and whether each factory had the same contamination problems.

As I was doing a little more research for this article, I came across some really fantastic breaking news. Blue Bell is going to be back in stores at the end of this month. You heard it here first, folks!! (or it may have come from this news article, too). I hope by summer’s end, you’ll all have access to all the cold, creamy, delicious ice cream you could possibly imagine.

So, my friends, let’s get to the fun (for me) part! The CDC and various States’ Departments of Health did an incredible job identifying the bacteria and tracing it to the source before too many people got hurt. Where else can we apply STEM toward solving this ice cream problem?

One of the first things that comes to me is by developing improved monitoring systems. (Why? Because this is an area I’ve worked at in my own job, of course!) Ice cream begins its life as a liquid. Is there a way to somehow continuously filter that liquid to isolate and/or test for bacteria? Bacteria have basic genetic and chemical difference from dairy byproducts that would make them pretty easy to tell from ice cream product, assuming you could clearly identify bacteria even at very low contamination levels.

That could work for plain chocolate, vanilla, or even superman, but what about the chunky ice creams? What if you have chocolate chips, cookie dough, brownies, sprinkes, or some other goodness in the ice cream? What if there’s a contaminant in the solid chunk? How could we identify that? Would it be better to grind up all the solid parts into tiny pieces and analyze the powder that’s left, or is it better to test the ice cream in its more natural, chunky form? I don’t know! That’s a big problem to think about.

The next thing that comes to my mind is how the company cleaned their manufacturing line enough to be absolutely sure there will be no further contamination. Usually, when I work with bacteria or other biological things, the most common methods of sterilizing are bleach, UV light, or a high-pressure/high temperature cleaning using a machine called an autoclave.

In the case of making food meant for human consumption, I prefer bleach not be involved in the process – but that may be how the machines are cleaned. I imagine most of the machinery is far too big to be put into a high pressure chamber, and there may be parts within the machines where UV light won’t reach. In that case, I assume some other form of chemical cleaners are used to kill the bacteria, but I don’t know for sure. Wouldn’t it be great if we had some young STEM lady or gentleman to improve the cleaning and sterilization processes within the factory, so that safe, non-toxic, inexpensive cleaning methods can be used?

Lastly, as I think about all my friends who’ve been deprived of a summer of ice cream, I think about supply chain management – how can we quickly and efficiently get the product back out to as many consumers as possible? Which types of ice cream should phased-in first, in what order should manufacturing lines be brought back on-line, and where should the newly-made, safe ice cream be shipped first?

There are so many questions, and so many great ways we can use STEM to improve ice cream accessibility and safety. I think I’m going to grab myself an ice cream, and think about how I can get myself a job in one of the ‘coolest’ industries I can think of! Let me know how you’d use STEM to improve the ice cream industry!




Love Travel? Try STEM!

STEMtravelHave you guys missed me? I’ve missed you lots, but I’ve had an amazing few weeks, months even! I know it’s pretty counter to the social media dogma, but I tried to shut off my phone, and live in the moment as much as possible.  But now, I’m back, and ready to talk STEM again.  I’ll try to share some of the highlights of my travels with you in detail over the next several weeks, but first let’s talk about why STEM may be an awesome career choice if you’re like me and love to travel.

First, a benefit of most STEM jobs is that they usually come with great benefits packages, including lots of vacation time. You’ll probably also have a pretty good salary, which means you’ll have some spare money to use over your vacation time. In June, I went to Cedar Point with family to run a half marathon with my sister-in-law. It was my first half-marathon, which I was pretty excited about.

Pretty out of gas after a 13.1 mile Sunday morning jog - and getting geared up for rollercoasters!

In July, we went on a family vacation with my parents and sisters to go to Tennessee. I blogged about the week in Tennessee here. It was really fun to spend the whole week with my kids adventuring, exploring, and experimenting!  The lake we visit in Tennessee was created by the Tennessee Valley Authority back in the great depression by damming a river.  Much like the Hoover dam, this helped with flooding issues in the area as well as providing a renewable energy source.  The views on the lake are absolutely stunning!

With a view like this, you'd turn your phone off too!

Mr SciGuy and I just returned from Traverse City, MI with his family. If you’re not from the great state of Michigan, maybe you haven’t heard of it, but it’s a fantastic place to visit. If you think of the lower peninsula of Michigan like a mitten, Traverse City would be situated just about on the fingernail of your ring finger.

We took a ride on the biggest catamaran on the Great Lakes - we love the NautiCat!

It has 2 big bays that connect to Lake Michigan, and there’s lots of outdoor things to do, and also a big cherry and wine industry on the peninsulas around the bay.

Vacationing is an obvious way to get travel in, but there’s also opportunity to travel for your job in STEM, too! For example, Mr. SciGuy spent a week in St Louis, MO for job training. I also got the opportunity to go on a quick trip to Toronto, Canada last month for business meetings. I spent a full work day in (really awesome, inspiring, educational, and fun) business meetings, but got to spend the evening I was there downtown. We went to an Iron Chef’s restaurant (Lee, by Susur Le) which was fantastic, walked through downtown, and spent some time on the hotel roof, which had an incredible view of the Toronto skyline. I wish I could’ve squeezed in a trip to the CN Tower, but didn’t have time on this trip, because I had to fly home and re-pack my bags to go on another trip! Guess I’ll have to go back to Toronto again soon!

Love the Toronto skyline!

Love the Toronto skyline!

Now, let’s talk about my favorite method of work travel. If you go into academic research, scientific conferences are I’ll devote an entire blog post on another day to why conferences are so awesome. To summarize, though, conferences are a way to share your work with others, see the current research in your field from all the scientific leaders, and to get the opportunity to meet leaders in the field and develop new collaborations. A bonus? They’re usually held in pretty cool places.

Previously, I’ve been to local conferences around Michigan, and travelled to Chicago, Washington DC, Boston, and Puerto Rico. This summer, I had the opportunity to go to Budapest, Hungary for a conference on lipid research. Budapest was amazing! I spent workdays working at the conference and listening to seminars, but we had nights, plus the day before and the day after the conference to see the city. Our hotel was right at the end of the Chain Bridge, one of the most famous sights in the city. Originally, Buda was split into two cities: Buda, and Pest. When the two cities merged to Budapest, the Chain Bridge was the first bridge to join the two cities. Now, there are several more bridges throughout the city, but the Chain Bridge is the most famous.  The picture at the top of the blog is of the lions guarding the Chain Bridge.

The view from our hotel roof - the architecture in Budapest was phenomenal!

The view from our hotel roof, with the Academy of Science across the park – the architecture in Budapest was phenomenal!

The conference was held in the Hungarian Academy of Sciences, another very famous site in the city, and we were within walking distance of Hungarian Parliament, the Academy of Art, a cathedral, and several marketplaces. Plus, if you follow me on Twitter (@theSTEMinista), you might already know I got to go to dinner in a castle – I lived my own personal fairytale for a night! Later in the week, I toured the underground dungeon/labyrinth attached to the castle, where Vlad the Impaler (aka Dracula) was imprisoned – if you like haunted houses and scary movies, this labyrinth is something you have to see!

I ate dinner at a castle - it was amazing!!  What a princess moment!

I ate dinner at a castle – it was amazing!! What a princess moment!

Did I mention the science at the conference was really good, too?  I learned a ton, met great people, and might have a couple future collaborations up my sleeve as well.

So, to summarize, my STEM career allowed me to travel my heart out this summer: to Cedar Point, Tennessee, Traverse City, Toronto, Budapest, and home with my kids while my husband went to St. Louis. What a whirlwind! I loved the travel, but I’m pretty excited to be back home, and getting back into my normal routine. If travel is a goal you aspire to, STEM is one of the best ways to achieve that goal – take it from me!

As I get back into my routine, and enjoy the last, precious few weeks of summer, I’m looking forward to talking more about STEM with you and gearing up for the 2015-2016 school year!


You are a natural born scientist

Ever wondered what it looks like from the top of a mountain on a cloudy day?  This is it

Ever wondered what it looks like from the top of a mountain on a cloudy day? This is it

Have you all missed me? It’s summer vacation for most students, and I’m in the middle of my summer vacationing as well. This week, I’ve been lucky enough to spend the week vacationing with family – not just me and Mr SciGuy and the junior STEMkids, but also my parents and sisters and brothers-in-law. We’ve had a lot of fun, but blogging has not been a priority.

The other night, I was taking a quick look through Twitter, and noticed a couple posts from parents talking about STEM “a-ha! moments” with their kids. That got me thinking about something –

Kids start their lives out as scientists

We are all born as scientists. We begin life by first becoming aware that we have surroundings, and then observing them like crazy. We experiment with our surroundings to learn how things do or don’t work, and how we fit into the world around us. As we grow from children to babies, we supplement our sensory and experimental data with information through spoken word and eventually by reading. Kids often ask questions to a fault, but often times, their questions are quite insightful.  Questioning is a key way for kids to learn about the world around them.

Since I was spending the week with family, I paid extra attention to seeing the world through my kids’ young scientist eyes. It was so fun! Lots of moments that might normally just pass by in conversation, I purposely tried to refocus into questioning and learning moments. We saw a flock of geese, for example, which led to lots of questions:

Which goose is the leader? Why can’t they fly? Why are they molting? What is molting?

Brilliant question for a 2 year old:  which goose is leading the other geese?

Brilliant question for a 2 year old: which goose is leading the other geese?

We saw lots of bugs, spiders, butterflies, turtles, deer, fish, eagles, and hawks. We talked about each animal’s habitat, what they eat, etc.

Check out this guy!  I leaned in really close to get a picture, and my sister yelled at me, "bright colors mean poisonous!"  Thanks for the heads-up, sis!

Check out this guy! I leaned in really close to get a picture, and my sister yelled at me, “bright colors mean poisonous!” Thanks for the heads-up, sis!

We hiked and boated through mountains, and talked about what makes the fog at the top, and how layers of rocks are formed, and how rivers flow.

We dropped rocks into the lake to see if they float or sink, and what kind of noise they make, and we conducted a few experiments to see if you get wetter swimming or in the rain (for kids wearing life jackets, their heads get much wetter in the rain than they do swimming – kind of counterintuitive to me, upsetting to them LOL). We listened to the sounds of a sunny day, the sounds of a rainy day, the sounds in a thunderstorm, and the sounds at night.

We played hide and seek daily, which reinforced concepts of scale, and how to systematically perform a search. Aside from their inability to stop giggling as the seeker approaches, my kids are now awesome at hide and seek.

It was fabulous. I learned a lot by searching for answers to my kids’ questions, or from asking friends and family for their insights.  More importantly, I think we all had fun posing questions and looking for the answers.

So, if you ever get down on yourself, and wonder if you can do STEM, consider how far you’ve already come. You developed from a tiny human who knew nothing, to where you are now.

You know so much about the world works, but there is so much more you can learn. Instead of being intimidated by what you have yet to learn, think about how much fun your learning journey will be. Look at the world through the eyes of your four-year-old self, and don’t be afraid to ask the questions a child might ask. Sometimes, something that seems obvious may be very complex, or something that seems complex may have a very simple rationale.

Embrace your innate curiosity to better understand things. Question everything, experiment when you can, and look for resources anywhere you can. Don’t look at learning as a job, look at it as a challenge, or a game, and you will be amazed at how far you can go.

To those of you in America, have a happy and safe Fourth of July, and I’ll talk to you soon!  In the meantime, I’ll be using #kidscientists on Twitter to talk about STEM concepts discussed in my house – share yours with me on Twitter too (@theSTEMinista)

Friends, I took a longer absence than planned, and I apologize. Today, we’re throw-back Thursday-ing to talk about a space shuttle launch I saw in 2009.  How did that come up, you ask?  Let me explain…

Last night, I posted to Twitter about how the Northern Lights are visible further south than usual because of a solar storm. If you haven’t seen them, the northern lights are astonishingly beautiful – they almost look magical. I have great memories as a teenager of going on trips to northern Michigan with friends, and laying on a dock to watch the stars and northern lights.

I peeked outside a couple times last night to look for myself, but didn’t have any luck spotting them. Too bad for me! Guess I’ll have to make a trip up north sometime soon to get my northern lights fix.

Anyway, I digress.

@FLBeach_MG and I struck up conversation about the northern lights which then led to talking about what he does – space shuttle launches!! What a great job – really, really cool #STEM, with the side bonus of working in really, really nice places.  No northern lights, but usually no snow, either!

John shared some videos of space shuttle launches, which reminded me about the time I went to a space shuttle launch (more about that in a minute). Turns out, we were at the same launch: STS-119!  One of the last launches of the space shuttle Discovery.

John dug up this really cool video that shows not only what a bystander sees when they go to a launch, but also what you can hear over the radio, while showing a timed graph of the altitude, metrics, and clues about different phases of the launch process including a picture of the shuttle showing its orientation.

It’s a longer video, but very informative if you (like me) aren’t familiar with shuttle launches. There’s a lot that happens after 3…2…1… A couple minutes after liftoff, the solid rocket boosters (SRBs) come off. These provide the primary thrust in the first two minutes. They are super heavy (2.6 million pounds) but provide 13,800 kN of thrust – wow!

I was surprised to see on John’s video that there’s actually a descent about 5 and a half minutes after liftoff. A maximum height is reached, and then the goal changes to building speed. During this phase, the shuttle rolls over to what we think of as an upright position. (John asked astronaut Nicole Scott why, the shuttle was head-down before TRDS, and reports her response “We’re pilots.  We like the horizon”.  Makes sense, right?) It goes through a downhill slide of several miles in altitude drop, and then starts to gain altitude again to go into orbit. Less than 8 and a half minutes after liftoff, the main engines cut off, and the external tank is released (John and other space experts out there, please correct me if I’m mistaken, or over simplifying!).

Thanks to John, we can see that after only about 8minutes and 30 seconds, the shuttle accelerates from rest to a speed of more than 16,900 miles per hour, and an altitutude of 65.3 miles. Also, the space shuttle is nearly 800 miles away (down-range) from where it started in Cape Canaveral. That’s an average of about 94 miles – per minute!! Too bad we can’t all get around that quickly!

Here’s another narrated video John shared which shows up-close vantage points of the features pointed out in John’s video.  One thing that stood out to me is how much show there was when the SRBs come off, versus a relatively peaceful release of the external tank.  The external tank was a little more like hippos doing ballet in Fantasia (at least to me).  Also interesting to me, which is pointed out in the video, is that there is a several minute window after liftoff where the shuttle can be averted and return to Earth should anything go wrong.  I always thought there was no going back once you’re in the air, but if the shuttle can land on a runway on return, why not return to runway in the case of an aborted mission?  Again – makes sense! For much more detailed information, check out NASA’s website. They have tons of great resources available for readers at all experience levels.

Even though it’s not my area of expertise, I’ve always had a fascination with space shuttles. They’re just plain cool, right? Mr. SciGuy is an even bigger space lover than me, though. In 2009 before we went on a vacation to Florida, he brought up that he was bummed because we were just missing a shuttle launch, and he’d always wanted to see a shuttle launch.  And Discovery was nearing retirement, so opportunities to see it were dwindling.

Bummer, right?

Actually, not so much.

Turns out the launch faced delay after delay. First, the mission team delayed the launch to examine (and then replace) the hydrogen flow control valves that send hydrogen from the fuel tank to the engine. Then, the launch was delayed because of a hydrogen vent line was leaking. If I remember correctly, the launch was then rescheduled to March 15 based on the weather conditions– this was a day we were scheduled to be in Florida, with no other plans (except now to go see a space shuttle launch).

nasa1So, we packed some bottles of water and our camera and drove from Tampa (on the west coast of the state) to Cape Canaveral (on the east coast). The launch was in.cred.ible. It was more intense than I imagined. The general public can’t actually get anywhere near a shuttle launch. We went to a beach in Titusville, ~10 miles away from the ACTUAL launch. At first, I was a little bummed. 10 miles away – could you even see something from 10 miles away? Let me tell you. Yes.


The light of launch, from 10 miles away was staggering. The noise? Even more intense, but the sound travels slower than the light. For a second, you think, “wow, that’s really bright.  too bad we can’t be closer”. Then, there’s a rumbling like nothing else you’ve ever felt, and you think “oh – now I understand why we shouldn’t be any closer”. You can feel in completely to the core. It’s really cool.  And then things really get moving.

<<Side note: after posting, John sent this video too, which shows damage to brick walls at the launch site following launch.  First, seeing people and work trucks in the area gives a great sense of scale about just how big a space shuttle and it’s launch gear is.  The damage to the wall itself may not seem super impressive – just some missing bricks, right?  Until about 2 minutes into the video, when you can see just how far the brick debris was thrown from the launch site.  There’s a reason they keep the general public miles away!  Good thing we did kinematics in my last post, because projectile bricks would be another really fun physics problem.>>

Beautiful reflections in the vapor cloud

It’s amazing to watch the shuttle slowly leave the ground, and head toward space. Then, too soon, it’s gone from sight, but there’s a veil of excitement still in the air. And, in the case of this launch, there was a killer reflection of the sunset off the vapor trail. Even the launch director called it the most beautiful launch he’d ever seen. I’m clearly an amateur photographer, but I’ve included some of my favorite pictures from the night in the post to try to convey the beauty.

Big questions lay in the sky - literally and figuratively

Big questions lay in the sky – literally and figuratively

Did you notice this one, where the vapor trail looks like question marks? It was windy, and the wind blew the vapor trail into a really cool pattern. I’ve used it in a number of presentations during Q&A segments. Turns out John and his team did some calculations based on the time of flight, and altitude at each time (see the video), and determined the big question marks in the sky were at about 16,000 ft altitude.  How many of you readers are thinking in your head that it would be amazing to spend a couple days in John’s shoes?

Have you been to a space shuttle or other launch experience?   What was it like for you? If not, how do you envision the future of space shuttles? Do you think they’ll still be a rare occasion worthy of a special trip, or do you think eventually they’ll be as routine as watching airplanes take off at a busy airport?

Cool STEM – roller coasters!

roller coastersWhen they were kids, my husband, Mr. SciGuy and his sister had season passes to Cedar Point. They practically grew up there, and they have countless stories about riding the roller coasters, playing in the arcades, and generally making mischief throughout the park.

Every year, SciGuy asks me if I want to go to Cedar point with him, but until last year, it never worked out. We had other vacations planned, or visited other amusement parks, or I was pregnant and couldn’t ride roller coasters.

Finally last October, we took our first family trip to Cedar Point. We had so much more fun than I expected, even bringing along two little kids. I thought it might be boring bringing to bring them to an amusement park, but I had more fun than I imagined watching them on the little kiddie rides.

kids on the kid rides: way funner than you expect

kids on the kid rides: way funner than you expect

This year, my sister-in-law and I signed up to run a half marathon at Cedar Point, so we had another opportunity to spend the weekend there. Being such a roller coaster enthusiast, SciGuy told me I just had to talk to you gals and guys about roller coaster engineering. I bet you could already guess that there aren’t a ton of roller coaster jobs out there – but there are some. It seems like the companies making the MOST popular big roller coasters are Intamin and Bolliger & Mabillard. There are numerous smaller companies out there as well.

Are you interested in roller coaster engineering? If so, most of all, you need to be really dedicated and passionate about it – there aren’t a lot of jobs out there, so there is stiff competition. Do what you can to learn everything about roller coasters, and get involved in professional organizations or clubs, such as the American Coaster Enthusiasts to learn more about the field, and meet industry professionals. There are a couple of universities which offer specific courses on roller coaster design, including Purdue, Ohio State, and North Carolina State University.

Want to hear about our trip, and some of the roller coasters we rode?

SciGuy and his sis, giddy after a morning of roller coasters

Our tickets included early access to the park an hour before it opened, so we had the opportunity to check out all the big roller coasters before it was open to the general public. It was so fun! We rode the Millennium Force first. It has been around for years now, but it is still consistently rated as one of the best roller coasters in the world.

Next, we rode Rougarou, which is the old Mantis rollercoaster, with a different floorless configuration. Then, we rode the Iron Dragon, an older steel roller coaster built in 1987 which is pretty tame in comparison to today’s roller coasters.

Then we walked back to try out the Maverick, which none of us had been on before. The Maverick was intense! It uses linear accelerator motors to propel the car up the first hill, then you go down the hill at a 95° angle. That’s crazy! The original design of the roller coaster had to be modified after it was built, because one of the turns was so intense that it put too much strain on the roller coaster car.

When he finished on the maverick we went to the Gemini, an old wooden coaster with steel tracks. After riding on the steel roller coasters, the Gemini felt almost as rough as being in the dinghy in a hurricane. But it was nice to get a historic ride in while we were at the park.

Riding the Gemini kind of turned me off from roller coasters for the rest of the day but the SciGuy and his sister still wanted more. They hopped in line for the Top Thrill Dragster as the last ride we had time for in the morning. If you haven’t heard about this roller coaster, you should look it up.

It’s classified as a strata roller coaster which means it goes more than 400 feet up in the air and then 400 feet straight back down. It uses a hydraulic system to push the car up to speeds of 120 miles an hour to accelerate over the hill. At the time it was built it was the tallest and fastest roller coaster in the world. The whole ride only takes 17 seconds but it is a really fun. Below, I put in a video of SciGuy and his sister riding it. If you haven’t seen it before, you can kind of get an idea of just what kind of roller coaster of talking about.

The hydraulic system on the Dragster can be very sensitive to environmental conditions, such as wind, rain, and humidity. Sometimes, this results in a train being accelerated up the track, but not making it over the crest. In this case, retractable braking fins catch and stop the car as it heads back to the starting gate. If you’re one of the lucky people that happens to, you get a bonus ride to get you over the hill. When the ride first opened, I remember seeing this happen several times, perhaps as the ride operators were really getting to know the nuances of the system. It doesn’t seem to happen as much now, but I don’t know if it’s because the kinks are worked out of the system now, or because they close the ride in bad weather conditions.

SciGuy did some more research, and found that there have been THREE times in the history of the ride where the car has gotten stuck right on the exact crest of the track. Can you even imagine that? Enough energy to get you to the top of the hill, but not enough energy to push you all the way over. When this has happened, they’ve had a mechanic climb to the top of the ride (>400 feet!!), who manually pushes the car over the hill. I wonder which way it gets pushed – if it’s back toward start, or toward the ending?   Can you imagine being on the ride for that experience? It’s like the ride of a lifetime!

Have you taken physics 1 yet? Where you study kinematics? This is like a dream introductory physics problem. If the train car must go a distance of 420 ft (128 m), and the only force acting on the train is gravity (9.8 m/s2), what starting speed do we need (assuming speed at height of 420 feet is zero). Using the formula v2 = vo2 + 2ax we calculate a speed at the bottom of the hill of 50 m/s, or 112 mph.

This is pretty close to the reported speed of 120 mph (53.6 m/s). We can then figure out how fast the train needs to accelerate from the starting gate to go from a starting velocity of 0 to the a velocity of 53.6 m/s, over a time of 3.8 s (thank you Wikipedia!). If we assume a constant acceleration (hydraulic launch systems are pretty constant), then we get an acceleration of 14.1 m/s2. Dividing by 9.8 m/s2, we can see that the average acceleration is ~1.44 G’s.

For those of you who’ve taken more physics courses, we can start adding in all the other variables that we ignore in the simplified kinematic model to make our modeled calculations fit better with the actual data. We can look at losses due to friction, weight distribution within the car, losses going around a 90° angle from horizontal to vertical and in rotating around the vertical axis, and losses due to wind speed and humidity, and other factors. How fun! I wish I had more information about the system so we could do more math!

What’s your favorite roller coaster? Have you ever done the physics to see what you’re experiencing?


STEMinista’s Dinner Party Advice

Nobel Dinner2

Wow, I’ve been gone a few days – sorry about that! Did you miss me? I sure missed sharing with all of you!

Those of you who follow me on Twitter or Facebook know I took a long weekend off for some family time. I have so much to catch up with on with all of you, starting with my second post about meeting Dr. Harald zur Hausen last week. More updates to come in the next few days – can’t wait to tell you all about my big weekend!


So did I mention I got to meet a Nobel scientist the other day? In the science world, Nobel Laureates are the types of people who should get baseball cards. They’re absolute rock stars for being intellectual athletes.

What I don’t think I mentioned yet is that by some great accident I got seated at a table with Dr. zur Hausen and a number of other absolutely inspiring leaders in science, medicine, and surgery at the welcome dinner the night before the talk. Let me draw you a little diagram to explain – STEM smarties love diagrams, right?

wow - look at all the incredible company I was honored to dine with!

wow – look at all the incredible company I was honored to dine with!

Do you see what I’m seeing here? I was literally sitting at a table with people who are giants in their respective fields. All but one have been doing what they do since before I was born. Literally – they’ve been doing their job longer than I’ve been alive.

I go to business dinners pretty regularly, so I’ve grown to be a little more comfortable in groups this impressive. However, no matter how many dinners I go to, I am always inspired by the people I dine with. If you’re new to dinners like this, and feeling a little intimidated, I thought I might share some of my advice with you.

Let’s start with the obvious. Be polite and mind your manners. I’m not really an etiquette expert – I’m a scientist. There are books and advice columns on that if you need advice, and parents, grandparents, and other adults are great resources. I recommend “The Essentials of Business Etiquette: How to Greet, Eat, and Tweet Your Way to Success” or “Modern Manners: Tools to Take You to the Top” (note, link will direct you to external website).
My true advice actually echos something that my grandmother used to tell me over and over and over as a child:

When you are lucky enough to be in the company of the greats in your field, or any field, shut your mouth and listen as much as you can.

Of course, it’s okay to chime in as appropriate. You should definitely ask as many questions as you can, but don’t waste a lot of time talking about yourself; Instead, spend your time listening listening listening and trying to soak up as much information, expertise, and advice as you possibly can from someone who has an entire career under their belt.

What’s cool about sitting with senior professionals? People who have been in the field for a long time typically love what they do. They’re passionate about it, and are often happy to share their experiences and insights. Most are also very excited to help the youngest generation in their field develop into leaders. They WANT to see you succeed.

Also, they really KNOW their stuff. They are like walking encyclopedias of their field. They can give you an entire history of the field over dinner, highlighting all the key people, the big findings, and the current and past key controversies. Why wouldn’t you take advantage of an opportunity to hear about all of those things? Think of the value of all the information you can get – you can go home with a full belly and a full mind!

If your dinner company works in a field that you’re interested in, they can tell you hot areas for research or jobs, they can tell you what leaders in the field look for in young professionals, and they can tell you what you can do to help break into the field.

You might also find that the conversation doesn’t revolve strictly around STEM. Perhaps it wanders through areas of hobbies, or family, or travel, or philosophy, or any other number of things.

Keep listening.  There’s more to life than STEM.

You might find a parallel to your own life. Maybe now, maybe later in your career, this information could be of use or importance to you. It could directly parallel your life, or it could help you gain a perspective on a different generation, a different culture, or a different lifestyle.

I can’t tell you all the amazing things I’ve learned from going to dinner parties, the great people I’ve met, and the wonderful connections I’ve developed.  When the opportunity comes up for you, make sure you take advantage of it, and listen, listen, listen as much as you can!

Thoughts on #distractinglysexy

distractinglysexyTonight, I wanted to share with you some advice about what one should do when dining with a Nobel prize winner, but this Tim Hunt #distractinglysexy thing came up. I posted on Twitter that I had a few reservations about the #distractinglysexy hashtag, and some people seemed a bit aghast – I thought I’d explain my point of view a little more – we’ll get back to dinner parties another night:

Most of us that are living in the current millenium agree that the statements made by Dr. Hunt are just plain wrong. STEM needs insights from all types of people, everybody has important input to give, and there are too many problems left to solve for leaving anybody out. We need all the brainpower we can get.

Is the problem that Tim Hunt doesn’t respect women in STEM? Is the problem that some men don’t respect women in STEM?

If so, does posting pictures of women on Twitter change Tim Hunt’s mind? Does it change any chauvinist man’s mind? Will we all wake up tomorrow in a STEM world without sexism or racism? We’re certainly bringing a lot of attention to the problem, but does #distractinglysexy actually solve a problem?

@niais posted a downright tirade about her feelings (warning: graphic language). To me, her comments were much clearer about explaining the problem(s) than any #distractinglysexy picture.

Perhaps instead #distractinglysexy will begin an open and honest conversation. Then, we can provide some data about the status of women in STEM, what areas need the most attention, and where we’ve already succeeded. @EmicAcademic does fantastic work on this, and @AAUW took the opportunity to begin posting all sorts of statistics and articles about Women in STEM – I believe THIS is the conversation we need to be having!

@D_avidH today pointed out the importance of understanding the problem and brainstorming solutions in STEM. I think the same thing applies here.  Everyone had something different to say about #distractingly sexy:

@CatholicSara said that #distractinglysexy is meant to make women laugh

@Bailiuchan suggested that satire can be a powerful agent of change

@coralnerd suggested this was an avenue of self expression for women in STEM

@dawnbazely suggested (not to me) that #distractinglysexy moved beyond Tim Hunt, and became a movement about women empowering themselves

First, thanks to each of you for your input and conversation – I think you all have completely valid points, and I learned a lot by considering your viewpoints. This is a situation where you are all right, and for the same reasons, I support #distractinglysexy if it:

  • Empowers anybody – man or woman – to pursue STEM.
  • Shows young people the diversity and exciting avenues of STEM careers
  • Encourages women and men in STEM to feel comfortable in their personal version of self-expression
  • Celebrates the accomplishments of women and men in STEM
  • Forms a support network of people in STEM to converse and share ideas with

Those things are incredibly important, and desperately needed. But personally, I have reservations about building such an empowering, uplifting movement if its very foundation is based upon tearing someone down. Even if that someone is wrong. Isn’t marginalizing someone else’s self expression the very thing we’re trying to prevent?

Instead, why don’t we create a movement based purely on positive foundations? Empower women and men in STEM every day – not just on days when some chauvinist makes a highly publicized sexist comment. For example@StephEvz43 has a great weekly video series on STEM and @Realscientists features different scientists on their website on a weekly basis with fantastic week-long outreach by each scientist. A couple weeks ago on my blog, I wrote a post about how I use STEM in my every day job. It was full of pictures that would be perfect for #distractinglysexy (before #distractinglysexy was cool). I didn’t write it as a one-time reaction to a rude comment. I wrote it because sharing my STEM experience could positively influence someone else.

We shouldn’t just be highlighting STEM when something negative happens. We should be celebrating STEM every day – celebrating little victories like passing a test or finishing an experiment, celebrating big victories like graduating, getting jobs, paper acceptances, patents, and discoveries. Instead of reactionary hashtags like #distractinglysexy, I’d rather celebrate and empower with constant positivity, such as #thankyouSTEMwomen, #scienceFTW, #heforshe, #heforSWE and @smrtgrls. I hope that opening a positive avenue of empowerment would

  1. Provide an environment of mentorship, camaraderie, encouragement which allows everyone to feel safe in their own form of self-expression
  2. open discussion to determine the problems, brainstorm possible answers and implement solutions, and
  3. develop a workforce of successful, empowered, educated STEM professionals

What do you think about the debate? Are there any key points of the discussion I’ve left out? I’d love to hear your opinion – the conversation is started – let’s keep it going
