Simply put, bottomlessly deep: that is the definition of a great discovery in science. From the principle of relativity to evolution by natural selection, the concepts that govern our world are actually not that hard to state. What they mean and what they imply—well, that’s another matter. And so it is with quantum entanglement. One […]

Gravitation is assumed to rule the cosmos, so models typically neglect magnetism, which for most researchers is just as well, because the theory of magnetism has a forbidding reputation. The basic equations are simple enough, solving them […]

(It is a complaint that many people who finally prevailed on spouses and roommates to clean up after themselves might appreciate.) How is it that, in sucking up surrounding […]
AUSTIN—A regular feature of American Astronomical Society conferences is an evening lecture on the state of science funding. Let’s just say it’s not a great date night. There have been happy counterexamples, but usually you spend an hour and a half hearing about the latest budget cuts and walk out of the room in a […]
