Third graders enjoy clay and pipe cleaners. It might sound cruel to teach them graduate level graph theory most math Ph.D.’s have not seen, but I might get away with it if I uses the right craft supplies. Tell kids spinach is good for them. Children are right to skeptical, as I expect of my reader.[The video is>

Ethan Siegel has just written an article, "The Science Has Spoken: Pluto Will Never Be A Planet Again", so this is a response to it. I'll argue that far from "story over", actually we could make a discovery tomorrow that would turn the whole thing on its head and make their definition untenable. This will become>

This is a simple build of a Michelson Interferometer using the SpyNet Laser Tripwire . About a year ago, I accidentally came across this toy and noticed that it has a red laser and two adjustable mirrors. It also has a receiver that will sound an alarm when the laser beam that shines on it is blocked. Yes, I have>

Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by watching other helicopters perform the same maneuvers.
The result is an autonomous helicopter than can perform a complete airshow of complex tricks on its>

An array of tiny, metallic, U-shaped structures deposited onto a dielectric material creates a new artificial surface that can bend and focus electromagnetic waves the same way an antenna does.>
