I have too many.
• Iguanas have two penises. And their pee is a powdery paste.
• Electric cars were invented around the same time internal combustion cars were, and accounted for like a third of car sales in 1900.
• You are more closely related to a starfish than you are to insects or octopuses.
• It is nearly certain that at least one molecule of water you drank today was once drank by Isaac Newton, Jesus Christ, and/or any historical figure you like.
• The Great Red Spot on Jupiter is at least 300 years old, eats other storms to gain their energy, and is three times as large as Earth.
• The atmospheres of Jupiter and Saturn transition smoothly from gas to liquid. Further down, the liquid is compressed into liquid metal.
• The 2010 iPhone 4 is about twice as powerful as the 2000 iMac, which weighed like 30 pounds.
• A perfectly deterministic mathematical function can eventually output random chaos.
• e^πi + 1 = 0
• There are just as many even numbers as there are whole numbers. There are just as many whole numbers as there are integers and fractions. However, there are more real numbers than integers. Both integers and real numbers are “infinite,” but the infinity of real numbers is greater than the infinity of integers.
• Graphene, the 1-atom thick sheet of carbon that recently got some people a Nobel prize, is almost completely transparent, is the thinnest material known to man, but is so strong that a graphene hammock could hold up a cat.
• You have basically the same number of hairs on your body as a chimpanzee.
• Weird kinds of lightning exist high above storm clouds. They include blue jets, giant jellyfish-like orange-red sprites, and spread out pulses called elves.
• Siphonophores are jellyfish that are both one and many. The animals clone themselves, and the clones take on different shapes and then come together to form a single, giant, colonial body, much like how your body is made of individual cells. The longest animal recorded is a siphonophore that looks like a snakelike chain of jellyfish.
• You can put a sponge through a fine-mesh strainer and the individual cells will come back together to form a whole sponge again.
• Italians never cooked with tomatoes before the 1500’s. Tomatoes only grew in the “new world.” Likewise, the Irish never cooked with potatoes before then.
• Nobody knows who wrote the four gospels. The earliest manuscripts are unsigned and undated. Assigning their authorship to Matthew, Mark, Luke, and John is a later church tradition.
• The Babylonian cult of Sin practiced “shabatu” days, roughly 4 times a month, that were considered so astrologically potent that you weren’t supposed to work or do anything productive. Sin, the Babylonian moon god, is cognate of “Mount Sinai.”
• The moon came into being when another, smaller planet smashed into Earth during the early days of the Solar System. The impact popped out a “bubble” on the other side, which became the moon.
• The passage of time appears to be a side effect (or epiphenomenon) of a wide-scale increase in entropy.
• Nobody knows how turbulence works. It’s one of the great mysteries in physics and math.
• Orbiting astronauts are pulled by Earth’s gravity almost as much as you are. Thus, they are not in “zero gravity,” they are in constant free-fall.
• Cats have extra eyelids.
• They also have barbs on their penises (to bring it full circle).
