Night 5.

Triangular numbers...Rewrite any number in the world as the sum of any two or three of them. The sum of any two consecutive triangular numbers is a perfect square.

Square numbers...pentagonal numbers, hexagonal numbers. Look into these. Cool stuff!

Prime numbers, night 3 I think.

Every even number greater than 1 can be written as the sum of two primes.

Every odd number greater than 5 can be written as the sum of three primes.

I need to find a local Gingko. Have I ever seen one? Are they the smelly ones? What about a turkey vulture? These elude me and I haven't found them to be all that common in all parts of NYC. I skipped some of that chapter.

Squirrels can rotate their feet 180 degrees? They also live in nests in trees?

Pigeons! Nests made of crap (literally), impeccable resources for navigation, relative to the dove, incredibly persistent. They depend on us humans for survival. Equality of parents. Oh yeah, Shakespeare is partly responsible for their downplayed role in nature.

Learned about Cardozo school and the first ever "teaching corps" in the 1960s, today's Teach for America.

Read about how Ts were fired for not supporting the wars...

Read about Brown v. Board and how it impacted teachers, black teachers specifically. Lost their jobs like crazy.
