Walkabout the Galaxy
psyche; general relativity
Astrophysics and Astronomy | Physics
A remarkably accurate test of general relativity confirms that not only does time run slower at your feet than at your head, but it runs slower at your eyes than your eyebrows. Plus, Psyche loses some of its metallic sheen, and we have spacewalk trivia and much more.
Whether you need to get directions to the nearest restaurant on your smartphone, or test the general theory of relativity, ditch those pendulum springs and quartz crystals and get an atomic clock. Available in hyper-accurate near-absolute zero models, still astoundingly precise room temperature models, and pocket-sized commercial models, atomic clocks take the "tick tock" out of timekeeping and replace it with atomic fountains and hyperfine transitions. If you find yourself running late, make sure your timepiece runs exactly right with atomic clocks. Atomic clocks, scrupulous attention to detail (Rolex).
