IT WAS while serving in the German army on the Russian front that, in the winter of 1915-1916, the physicist Karl Schwarzschild sent Albert Einstein some papers. He had solved Einstein’s equations of ...

Answering some of the biggest questions in astrophysics—for example, about black holes and the origin of the universe—might require overhauling general relativity. In this artist’s illustration, ...

THERE is, as Mr. Browne points out, a lapsus calami in my quotation. The supposed velocity of the cannon-ball is, not a twenty-thousandth of, but less by about a twenty-thousandth than, the velocity ...
