Friday, July 26, 2013

It's high summer, yes, but blink and soon it will be fall, and trees will turn red, brown, beige, yellow, pale green and gold. But not cars. Cars may be making the Earth warmer, but their colors, I notice, have turned wintry.

Friday, July 19, 2013

If you can't get to a beach this weekend, you can still see waves. Just look up.

'Why You? Why Now?' A Med Student's Journal

Saturday, July 13, 2013

I guess doctors, especially doctors-in-training, have to get used to sudden, inexplicable endings. You are trained to heal. That's the goal, that's the point. But every so often, you don't win. Something you didn't see coming, comes. I don't know which hurts more, the 'suddenly' or the 'why?" If the ...

What is rarer than a shooting star?

Rarer than a diamond?

Rarer than any metal, any mineral, so rare that if you scan the entire earth, all six million billion billion kilos or 13,000,000,000,000,000,000,000,000 pounds of our planet, you would find only one ounce of it?

What is so rare ...

Democracy, My Mother And Toast

Tuesday, July 02, 2013

When they proposed it in the 1770s, it was such a novel idea. That instead of a king anointed by God, instead of a sage, instead of one leader telling all of us what to do, we should, every four years, all of us, pick our own leader, who would ...

A Beautiful Notion: That Caterpillars Killed Off The Dinosaurs

Monday, July 01, 2013

For the last hundred years, scientists have been wondering why the dinosaurs disappeared so quickly. Was there one key reason, or several?

Stroke, Stroke, Stroke — The Atlantic Ocean's Dazzling Oarsmen

Saturday, June 29, 2013

At night, in the ocean, they look like little Broadway billboards with dazzling trills of rainbow colored light. They have eight little runways on their bodies for light display. What are they?

Weekend Special: What If A Cricket Fan Had To Suddenly Announce A Baseball Game?

Saturday, June 22, 2013

This isn't going to be sciencey. This is just total, happy craziness. Suppose you have never seen a baseball game. All you know is cricket, and somebody sticks you at a Yankee/Red Sox game and says, "Do the play by play. Now. You're on!" There's no time to prepare. You ...
