13Cribsheet.jpg The latest addition to SEED‘s excellent Cribsheet series: Light. On one page, everything you wanted to know or remember about the electromagnetic spectrum, wave-particle duality, how light interacts with matter, how we use light to study the size, age, and composition of the universe, how light can help provide clean energy, faster computers, and efficient space travel. Check out other Cribsheets on everything from hybrid cars to nuclear power to extinction to genetics, to name a few.

BEFORE YOU CLICK AWAY!

“Lying.” “Disgusting.” “Scum.” “Slime.” “Corrupt.” “Enemy of the people.” Donald Trump has always made clear what he thinks of journalists. And it’s plain now that his administration intends to do everything it can to stop journalists from reporting things they don’t like—which is most things that are true.

No one gets to tell Mother Jones what to publish or not publish, because no one owns our fiercely independent newsroom. But that also means we need to directly raise the resources it takes to keep our journalism alive. There’s only one way for that to happen, and it’s readers like you stepping up. Please help with a donation today if you can—even a few bucks will make a real difference. A monthly gift would be incredible.
