You wouldn't know it, not right away, but there is something strange about this picture. It's a sunset, yes, but notice the blush of color right above the sun. It's blue. And as you look up, the blue fades into a faint rose or pink.

I don't remember who told me this tale, but it begins with a little boy, maybe 4 or 5, who is given a book. He opens it, begins to read, curls into it, won't look up, can't stop, looks at the pictures, turns the pages, keeps turning, turning, turning, until all too quickly, he's done, finished.

Take a look at this picture:

Those same coils — the ones that look like the side of a snail — are also found on the Big Island of Hawaii, which were formed by lava flows.

Still scientists found that they are "morphologically consistent with terrestrial lava coils."

Publius Paquius Proculus, they say, invented pizza almost 2,000 years ago. I don't think he did, and anyway, that's not the coolest thing about Proculus, a very successful baker and sometime politician, who was living in Pompeii the day Mt. Vesuvius erupted. He, his house and his family were buried. Then, centuries later, when archeologists unearthed his home they discovered a message, etched onto one of his household walls. It looked like this:
