Stuff You Missed in History Class

Solon is one of the seven sages of Athens, and he's credited with laying the groundwork for Athenian democracy. But most of what we know about him comes biographies written centuries after he lived.

Once Dr. Ray Damadian had the idea to create a machine that used nuclear magnetic resonance to capture diagnostic data by scanning a human body, he still had to build it. And though he did, other scientists got credit for inventing the MRI.

People started adding iodine to salt because in some parts of the world serious, chronic iodine deficiency was incredibly widespread, which was causing a range of health issues. But how was that solution arrived at?
