Whale earwax

Hello World!

The other day I was talking to my local librarian and we got to the discussion of whale earwax. I don't remember how that happened, but what I do remember is that she told me that whale ear canals absorb all the toxins in the environment. They wax acts as a sort of thermometer for how well anti pollution efforts are going and to help determine whether or not there are still chemicals that have long since been banned (sadly, these agents are still lurking!). I will share the source of this knowledge soon. In the meantime, just imagine all the other careers out there! I certainly didn't know analyzing whale ear wax was one, but science never ceases to amaze!

Science of sound

Hello World!

Did you know that you can study both music and the brain? You can! Music has a unique impact on brain waves, from helping people with Alzheimer's to motivating people to move. One of my favorite films is "the musical brain", you can also read more in this recent article

May we all find our rhythm in STEM

You are CuTe

Hello World!

Today we have fun with the elements!

I did not come up with that but I think it is hilarious, fun, and well, 1+ 53+15 ;) to figure out what  word I spelled using the atomic number of element in the periodic table or have fun learning about chemistry check out

Science of Roller Coasters

Hello World!
I apologize I have been slacking on the blog department lately, things have been quite busy... lots of fun science from diversity and culture to vision and STEM advocacy, even a little break for a theme park! Which brings me to today's topic- Roller Coasters! To me they are the definition of summer (almost over or almost beginning depending on where you are in the world). The speed, the thrill, the physics! The science of perception! What's not to love?

Picture I took at Universal

One of my favorite rides was advertised as a "psychological thriller" and involved cognitive elements of surprise, fear, falling, and more, in addition to the elements of speed, thrill of inversion, and surprise twists and turns. What is even cooler than the experience is the elements of STEM that go into it! Just think, you could design the ride, the safety measures, the lines that people must wait in, or the rides themselves. This woman didn't realize she was going to be a roller coaster professional, but she loves it!

Interested in designing your own coaster? Check out this link http://www.discoverengineering.org/
or this blog about roller coasters http://www.coasteroftheday.com/how-to-design-roller-coasters.html  it highlights the importance of passion and imagination in conjunction with science skills.

Well, back to my roller coaster ride of life!

Bling and your eyes

Hello World!

 In my last post, I spoke about celebrity news articles that speak of "cornea searing" rings. I thought it would be fun to examine this concept more closely. The cornea is the clear part of your eye, front and center, it provides shape, protection and refracting (bends light) power. It is kind of like gel. To speak of cornea searing rings refers to the exponential increase (10x) in brightness that occurs when light bounces off shiny, reflective objects such as bodies of water, snow, and maybe some rings but that would be a really big diamond! What you really need to worry about though is the damage you get from the UV light you don't even see. That is why it is so important to wear sunglasses! You can learn more about that here  http://www.visionweb.com/content/consumers/dev_consumerarticles.jsp?RID=52 

This picture from a rocket launch shows how bright light reflects off water, now that is some bling!

Have a super day!

Bling in the night sky

Hello World, 

Do you like shiny sparkly things? I know I do! The best sparkle, I think, comes from our night sky.

But for those who prefer gemstones, stay tuned! Next time we will discuss the science & truth (or not) of recent news on celebrity "cornea searing" rings :) 

Hurray for GoldieBlox!

Hello World!
I was so pleased to see this article
http://www.nbcnews.com/business/no-more-ironing-boards-engineer-aims-reinvent-toys-girls-6C10629732
A female engineer has put together kits that encourage girls to build, design, and engineer their way through a story with GoldieBlox, the main character. This kit will be sold in major toy stores. This product is very important because socially girls do not grow up tinkering with engines or building things, which inhibits spatial skills needed in many STEM careers. Now girls can obtain those skills in a manner that speaks to them! Plus, not everyone has old cars or lives in a space that will allow for such tinkering. (For girls who did not get spatial skill development, there are training programs that will help you catch up (see prior post or AAUW report why so few?)).

I didn't grow up looking at engines, but I do remember watching and helping my dad build barns, sheds, and all manner of things. I also remember trying to play with my brothers electronic set too (it was a boring gray color). I like that she based her product on research and watched the difference in play between boys and girls. She found a way to merge differences in styles and I appreciate that she doesn't just paint it pink, nor take away from "being a girl". I hope her future products feature characters that represent women from all cultures and stories. In any case, pretty awesome that you can be a women, an engineer, an entrepreneur, and a major positive social change agent! Love this!
