## Forget What Your Teacher Said: Mass And Weight Are The Same

At high school, your physics teacher probably drummed it into you that mass and weight are completely different things — but actually, they were wrong all along.

## An Unsettling Reminder To Water Your Plants

Keeping flowers or plants in your house is supposed to make things more beautiful, not chaotic. But this vase is only balanced when the flowers have water. If too much liquid evaporates, the counter-weight pulls one side of the vase down.

Earth is getting 50,000 tonnes lighter every year, even while 40,000 tonnes of space dust fall onto our planet’s surface during the same period. So, why are we losing so much weight? You will be surprised.

## 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.
