“Round numbers are always false.” — Samuel Johnson
“Why are numbers beautiful? It’s like asking why is Beethoven’s Ninth Symphony beautiful.
If you don’t see why, someone can’t tell you. I know numbers are beautiful.
If they aren’t beautiful, nothing is.”
— Paul Erdös
You can find the odds of rolling any number with two dice by subtracting the number from 7, ignoring the sign, and subtracting the result from 6. The remainder is the number of chances out of 36 that the number will appear.
For example, there are (6 – (7 – 5)) = 4 chances in 36, or 1 chance in 9, that you’ll roll a 5.
Light travels 186,000 miles per second. The average diameter of Earth’s orbit is 186 million miles.
So, on average, sunlight reaches us in a neat 500 seconds.
