(Phys.org)—Alex Harvey, a physics professor at the City University of New York has uploaded a paper to the preprint server arXiv, in which he claims Albert Einstein and Erwin Schrödinger were writing letters back and forth ...
BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) ...
