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!

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!
