    Mathematicians Have Just Reversed the Sprinkler

    For 141 years, physicists like Richard Feynman have puzzled over a question of fluid flow: how would a sprinkler rotate if it were underwater, sucking in the stuff instead of spewing it? Now, a team of researchers has found an answer. Though the idea was first proposed by experimentalists in the 1880s, it was repopularised…

    New Quantum Computer Milestone Would Make Richard Feynman Very Happy

    A commercially-available “quantum computer” has been on the market since 2011, but it’s controversial. The D-Wave machine is nothing like other quantum computers, and until recently, scientists have doubted that it was even truly quantum at all. But the company has released an important new result, one that in part realises Richard Feynman’s initial dreams…
