This should probably be required reading. #4 and #9 bother me the most on a daily basis.
I know that’s harsh, but I really feel my home country is not in a good place these days. That’s not a socio-economic statement (although that’s on the decline as well), but rather a cultural one. I realize it’s going to be impossible to write sentences like the ones above [Read More...]

#1 suggests us Brits are impressed by Yanks...er..no, we're really not.

Join us for a STEM Women HOA as we speak to +Annika O'Brien  on her career as a roboticist. Annika is an engineer who works on robotics and also a passionate STEM educator, teaching kids how to program and build robots through +STEAMtrax. She will talk to us about her exciting career path as a woman in STEM, what inspires her, and why supporting women in STEM is important. 

This HOA will be hosted by Dr +Buddhini Samarasinghe and Dr +Zuleyka Zevallos   and you can tune in on Sunday April 27th at 4.30 PM Central/ 10.30PM UK. The hangout will be available for viewing on our YouTube channel (http://www.youtube.com/stemwomen) after the event.
This Hangout On Air is hosted by Annika O'Brien. The live video broadcast will begin soon.

Amazing Alternating Arrows
Fun with physics

It's always great when you can find ways to bring a little science right into your home, and here's a simple experiment you can do to teach your friends, your kids, or your friends' kids a bit about refraction. 

From physicscentral.com:

No, you aren’t going crazy and you haven’t found yourself with Alice in Wonderland staring at arrows pointing in opposite directions.  In fact, you have just demonstrated a physics concept called refraction, the bending of light.

When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts.

Just because light bends when it travels through different materials, doesn’t explain why the arrow reverses itself.  To explain this, you must think about the glass of water as if it is a magnifying glass. When light goes through a magnifying glass the light bends toward the center. Where the light all comes together is called the focal point, but beyond the focal point the image appears to reverse because the light rays that were bent pass each other and the light that was on the right side is now on the left and the left on the right, which makes the arrow appear to be reversed.

and, just by the way, this isn't really an optical illusion.  An optical illusion (like the motion aftereffect illustrated in +annarita ruberto recent post on Fibonacci numbers: http://goo.gl/Qzq1Xi), is when your brain misperceives something that is physically represented a different way. In this case, the physical representation actually changes, so what you are seeing is a veridical percept, not an optical illusion.

Reverse Arrow Optical Illusion

Look Mah; I can do magic! This is a nice experiment to do with the kids. 

This is simply a demo of refraction: bending of light. #scienceeveryday

Story
Tagline
They tell me I'm human. I don't believe that one bit.
Introduction
Martin is a defective sentient being with humanoid form, but was not assessed by quality control officers at the human manufacturing facility. As a result, he is an over observative, over thinking, non-human humanoid citizen of the Multiverses, with a severe chronic allergy of reality and sports that is also prone to panicking in social situations.

Martin is an Internet Nomad.  He just drifts around on the winds of the Interwebs and avoids real life as much as possible.
