How a frozen beam of hydrogen helped scientists put the laws of physics to their toughest test yet
Cracking a 15 year physics mystery, researchers measured the precise size of a proton. In A Nutshell A team in Germany used an unprecedentedly precise laser measurement of hydrogen to pin down the ...
An international team of scientists confirms a surprisingly small proton radius with laser spectroscopy of exotic hydrogen. An international team of scientists confirms a surprisingly small proton ...
Big problems sometimes come in small packages. The problem with which physicists must now concern themselves measures a mere 0.0350 millionth of a millionth of a millimetre. This is precisely the ...
