'throw

Me, moments before strangling Eitan.

Madeleine and I walk Sonnet to the bus stop. At Cafe Nero: "It is so unfair that I can't have a treat."
Me: "Life is unfair. Let's do this. You ask me a question, anything at all, and I will see if I can answer it."
Madeleine: "Do we have to Dad?"
Me: "Give it a try."
Madeleine: "How did they know the world wasn't flat?"
Me: "That's excellent.  Let's see. People used to think the world flat and the sun and the moon circled around us. Kind of arrogant, don't you think?"
Madeleine:
Me: "When we are just one of a billion stars in the universe."
Madeleine: "That's pretty small, isn't it?"
Me: "We are smaller than a speck of dirt."
Madeleine: "Whoa."
Me: "Aristotle, anyways, over 2000 years ago, one of the first dudes to think the world is round.  To measure the curve, he knew that the sun directly overhead at the summer solstice, and so he was able to measure the angle of the shadow , which he did at Alexandria, which was about 1/50th of a circle, he estimated. Then he measured the distance Alexandria to Syene, another ancient city, and was able to use the two points, plus the angle, to determine the earth's circumference."
Madeleine: "Do you want to know three other ways?"
Me: "Of course."
Madeleine: "One. You can see the earth's shadow on the moon."
Me: "Excellent."
Madeleine: "Two. Ships disappear on the horizon and, if the world was flat, you would see them until they were a little dot."
Me: "Brilliant."
Madeleine: "And Christopher Columbus said so, too, when he sailed to America."
Me: "Good stuff, kiddo. Gold star."
