Earth’s spin and its bulging middle team up to loosen gravity’s grip, and the payoff is about half a percent lighter just by changing latitude. Here is the physics behind the planet’s quiet weight-loss…

Why Gold Is Gold: The Einstein Hiding in Your Jewelry
Look closely at the metals around you and you will notice something strange: almost all of them are silvery-grey. Steel, aluminum, silver, platinum, nickel, they all share that same cool, mirror-like shine. The reason is that a typical metal reflects every color of visible light more or less equally, so our eyes receive the full…
