I am impressed by how clever that was. Well done.

We had a young, hippy science teacher through 70s grade school. Looking back, that woman made more impact on my life than any other teacher.

Every year, every fucking year, she'd start with the difference in fact and opinion. "Yeah, I get it already. Can we move on?" Apparently not many others got that bit of education.

She taught the scientific method and how it works, she taught how to experiment, how to measure. I still set a beaker down and wait for it to settle before moving on. And I'm not in science!

NGL our solar system being the size of a finger print is (somehow) bigger than I expected.

Another fun size thing I heard recently was that if an atom were the size of a football stadium then the nucleus would be the size of a pea.

A fingerprint? That's actually bigger than I figured.

There are definitely more hydrogen atoms in a mole of water than stars in the Milky Way.

The Milky Way has somewhere between 100 and 400 billion stars according to Wikipedia (1*10^11 to 4*10^11). A mole of water has 6.022*10^23 molecules in it, each of which has two hydrogen atoms in it for a total of 1.2044*10^24 hydrogen atoms.

10^24 / 10^11 = 10^13 which is ten trillion. So, a mole of water has roughly ten trillion times as many hydrogen atoms as the Milky Way has stars.

just the first part of the phrase

Seems to me like it was the last part of the phrase.

The average human has somewhere between 1.1 and 1.4 testicles.

Late edit: I was not sober when I wrote this and I definitely did the math wrong.
