    Physicists Measure Gravity of Smallest Mass Yet

    Despite keeping us grounded and warping light that travels through space, gravity is actually quite a weak force. The smaller the mass, the less gravity appears to have any pull, until at quantum scales it appears to have no force at all. Now, physicists in England and Europe have measured a tiny—but apparent—gravitational pull on…

    Physicists Measure the Smallest Gravitational Field Ever Detected

    Over the Christmas season of 2019, four physicists hovered over two minuscule gold orbs, each about the size of a ladybug, in a Vienna laboratory. It was silent, in all the ways you can imagine: audibly, seismically, even electromagnetically. It had to be, as the researchers were trying to detect the influence of one of…


  • Your Kindle Gets Heavier As You Add Ebooks To It

    Moustachioed UC Berkeley computer science professor John Kubiatowicz told the New York Times that your Kindle gets heavier when you add ebooks. Don’t worry, though, you won’t feel it with your hand, or with any scale that we’ve ever created.
