Ever tried to picture how much one rocket weighs compared to another, or how heavy some of the craft orbiting our planet really are? Well this chart explains all.

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. In this video, Professor Mike Merrifield from the University of Nottingham — along with Albert Einstein and Isaac Newton — explains the equivalence principle. It says that mass and weight are, really, the same thing.
The Higgs boson discovery is a good excuse to learn a bit (and just a bit) about why it was so damn important in the first place. By now, you've probably heard that the Higgs is the final piece of the standard model of physics. But what does that actually mean?
We've long known that there were some issues with France's 'Le Grand K', the international prototype for what a kilogram really is. Made in 1879 from platinum and iridium alloy, it is the perfect standard for what a kilogram weighs. The problem is it's losing weight.
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.
Yesterday we got a peek at the combined power of nanotubes—technology that makes a rope-driven space elevator feasible—but what can just one do on its own? Berkeley researchers have discovered that one nanotube can be used as a tiny platform to determine the mass of a single atom.
