15 Awesome Chemistry GIFs. You don’t need to watch Breaking Bad to know that chemistry is pretty awesome.
Below, we explore our favorite 15 chemistry GIFs and the science behind them (when we could figure it out): Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it. The metal slug’s electric resistance causes a portion of the electric energy to turn into heat, but the heat builds up until the metal slug becomes white hot and melts. Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on.
Awesome Chemistry GIFs: Heating Mercury Thiocyanate Hydrogen Peroxide Catalyzed By Potassium Iodide. Des chercheurs sont parvenus à contrôler la queue d'un rat par la pensée. Jeudi 1 août 2013 4 01 /08 /Août /2013 13:00 Des chercheurs sont parvenus à contrôler la queue d'un rat par la pensée VIDEO - L'université d'Harvard a réussi la prouesse d'établir une interface entre un homme et un animal.
Ceci n'est pas une blague. En juin déjà, un ingénieur lillois publiait une vidéo dans laquelle il parvenait à contrôler une maison domotique par la pensée. Cette fois, l'université d'Harvard va plus loin dans l'exploitation de la télépathie. Révélée par le Huffington Post, cette étude marque une nette avancée dans l'histoire de la télépathie.Jamais encore, l'homme n'avait réussi à contrôler un animal par la simple pensée. Les chercheurs de l'université d'Harvard ont mis en place une interface qui transmet un message électrique via un casque relié au cerveau de l'homme et à celui du rat.

From creating fully functioning artificial leaves to hacking the human brain, science made a lot of breakthroughs this year. 1. Quadriplegic Uses Her Mind to Control Her Robotic Arm At the University of Pittsburgh, the neurobiology department worked with 52-year-old Jan Scheuermann over the course of 13 weeks to create a robotic arm controlled only by the power of Scheuermann’s mind.
The team implanted her with two 96-channel intracortical microelectrodes. 2. Once the robot figures out how to do that without all the wires, humanity is doomed. 3.

Using an electron microscope, Enzo di Fabrizio and his team at the Italian Institute of Technology in Genoa snapped the first photos of the famous double helix.Source: newscientist.com / via: davi296. Why Nikola Tesla was the greatest geek who ever lived. Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla.
Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life. The drunk history of Tesla is quite awesome, too. History.com has a great article about Edison and how his douchebaggery had a chokehold on American cinema.
