Einstein’s brilliant mistake: Entangled states
When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. But one of his greatest contributions to the field actually came in the form of an odd philosophical footnote in a 1935 paper he co-wrote — which ended up being wrong. Chad Orzel details Einstein’s “EPR” paper and its insights on the strange phenomena of entangled states.

The Cone of Invisibility
Invisibility - it’s something we’ve sought after for years, not just as Harry Potter and Klingon enthusiasts, but for practical purposes of concealment. But is there a way to hide something without the use of camouflage? Is there such a thing as cloaking? As the University of Rochester shows— yes! Kim Horcher and Bryan Forrest (Video Game High School, Man at Arms) discuss!

Quantum tunnelling sounds like science fiction, and does indeed feature quite often in the genre. But it is real, and plays a role in nuclear fusion, chemical reactions and the fate of the universe. Heres how it worksThe recent claim from
Lockeed Martin that a compact fusion reactor could be built soon is, if true, a breakthrough in engineering rather than basic physics. The basic physics of fusion has been known for some time, and a key element of understanding it is
