Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

The constant — the ratio of the mass of a proton to the mass of an electron — has changed by only one hundred thousandth of a percent or less over the past 7 billion years, the observations show. The ...

The discovery of a Higgs-like boson with mass near 126 GeV, at the LHC, has reignited interest in future energy frontier colliders. We propose here a proton-proton (pp) collider in a 100 km ring, with ...

Prereduction of the intersystem pool in isolated spinach chloroplasts leads to the appearance of a slow phase in the field-indicating 515-nm change induced by a flash. Measurements with the ...

Here's a question you've probably never considered: Why are all electrons the same? Every electron in the universe has exactly the same mass, exactly the same charge, and if you think about it, ...
