A counter-intuitive result.

Some quantum phase transition results from my old group at NIST

"We propose an atom-interferometry experiment based on the scalar Aharonov-Bohm effect which detects an atom charge at the 10-28e level, and improves the current laboratory limits by 8 orders of magnitude. "

Another factor of three improvement in the most precisely tested theory in science.

Love the title.

"Even in my mathiest courses I find it irresistible to doodle in the margins of my notes. I like to think of it as balancing the left and right sides of my brain but that's just sugar coating my short attention span."

"and arms can't do feel good got harm hey hold i in knew know like love me my nice no now so spice sugar that when whoa whoa-oa-oa won't would wrong you"
