Mostly Trivial #122 Crocodiles vs. Alligators trivia

Little Dinasaurs

The who's who of reptiles

After surviving nearly unchanged for over 200 million years crocodiles and alligators were hunted to the brink of extinction between 1900 and 1967 in a period as brief as a single man's life, how sad. Also their habitats continue to shrink. Today due to conservation efforts the American alligator is no longer on the endangered species list but many species of crocodiles remain at risk. Continued diligence is necessary if we are to preserve these incredible animals that open a door to the planet's early history and a window into an age of fantastic creatures that ruled the earth for tens of millions of years.

Mostly Trivial #121 Magnets trivia

Magnets.Very attractive!

If they ate spinach would they have more iron?

The discovery of the magnetic compass was an event of GREAT importance in the history of people. It was the first documented instrument created by mankind that could be read using a precise scale. Of course the sundial had been around for a long time, but it doesn't move [just it's shadow does as you know]. There was the wind vane, but no precise way at that time to measure wind direction. If you think about it, it's pretty hard to measure direction in general, without a compass. The earliest known compass surfaced in China by at least the first century A.D. It apparently didn't arrive in Europe until the twelfth century A.D [1100's]
