gbrumfiel writes "For years, physicists have been on the hunt for a material so weird, it might as well be what unicorn horns are made of. Topological insulators are special types of material that conduct electricity, but only on their outermost surface. If they exist, and that's a real IF, then they would play host to all sorts of bizarre phenomenon: virtual particles that are their own anti-particles, strange quantum effects, dogs and cats living together, that sort of thing. Now threeindependentteams think they've finally found the stuff that the dreams of theoretical physicists are made of: samarium hexaboride."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
