I love neutrinos. I’ve written about them over and over and over again because they’re super fascinating and we’re only starting to uncover their secrets. So naturally I’m psyched that the physics Nobel Prize this year was awarded to two scientists that theorized neutrino oscillation: The 2015 Nobel Prize in Physics was awarded this morning to two physicists whose teams discovered a fundamental property of neutrinos. Neutrinos come in three types: electron, muon and tau.
Fusion! Unlimited power! Superconductors! Yeah, this article is easy to dismiss as spin on fusion tech that is perpetually just ten years away. But two interesting things about this particular design: It uses new commercially available superconductors made of rare-earth barium copper oxide (REBCO) superconducting tapes that are capable of producing high-magnetic field coils. The stronger magnetic fields generated by these coils do a better job of confining superhot plasma, so the reactor can be smaller, cheaper and take less time to build.
Possibly my favorite part of this montage of dumb things filmed with a high speed camera is the physics. At 2500fps it gets really obvious that gravity and air resistance play a major role in slowing down fast moving things. Even small pieces of watermelon that are ejected by fireworks get noticeably slower right after the explosion. I won’t bother with the kinematics, I’m sure you get all the video analysis you need from Dot Physics.
