Galileo’s famous gravity experiment holds up, even with individual atoms
According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years,…
A measurement of positronium’s energy levels confounds scientists
Positronium is positively puzzling. A new measurement of the exotic “atom” — consisting of an electron and its antiparticle, a positron — disagrees with theoretical calculations, scientists report in the…
To live up to the hype, quantum computers must repair their error problems
Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit…
