NASA and industry partners lit up the Utah sky on Sept. 10, 2009, with the initial full scale, full-duration test firing of the first motor for the Ares I rocket. Engineers will use the measurements gathered from the test to evaluate thrust, roll control, acoustics and motor vibrations. This data will provide valuable information as […]
Sensing the motives and feelings of others is a natural talent for most people. But how do we do it? In the following video presentation, Rebecca Saxe shares fascinating lab work that uncovers how the brain thinks about other peoples’ thoughts — and judges their actions.
By Casey Lynn Contributing Writer, [GAS] According to an Australian psychologist, Facebook makes you smarter, but Twitter makes you dumber. Why? Well, it has to do with exercising your working memory. Staying on top of Facebook is like solving puzzles, since it hones our ability to remember and use information. But more “micro-level” activities like […]
I, for one, welcome our future rat-brain controlled robot overlord. This is no ordinary robot control system – a plain old microchip connected to a circuit board. Instead, the controller nestles inside a small pot containing a pink broth of nutrients and antibiotics. Inside that pot, some 300,000 rat neurons have made – and continue […]
While many students would surely like to own a 48-inch multi-touch screen, most don’t have the cash to buy a Microsoft Surface device. But a group of engineering students at the University of Waterloo in Ontario didn’t see that as a problem: they just built their own. Their device does not strictly work on touch, […]
Yes, it all makes perfect sense now! Pies are circular and Pi is often referred as the circular constant. No need to dig further, this has to be the truth. Edit: Before I get another email telling me I’m an idiot for posting this *sigh* , here’s a quick explanation of the true origin of […]
At his day job, Steve Truglia flips cars, walks through fire and falls out of buildings — pushing technology to make stunts bigger, safer, more awesome. In the following video presentation, he talks us through his next stunt: the highest jump ever attempted, from the very edge of space.
Isn’t that one of the most awesome thing you’ve ever seen? If anyone understands the science behind what’s happening in the video, feel free to leave a brief explanation in the comments section below!
Narrated by broadcaster and naturalist David Attenborough, the Tree of Life is a six-minute documentary that retells the story of life on earth, from its very early days up the present era.
In the following video, Evan Grant demonstrates the science and art of cymatics, a process for making soundwaves visible. Useful for analyzing complex sounds (like dolphin calls), it also makes complex and beautiful designs.
