Thanks. Cis-users always make me groan. I'll bet not one has ever taken a hard science class, and has absolutely no idea what the term actually means...
Probably my favorite class was organic chemistry. It's pretty cool, actually - carbon has four bonds, and they are all equal - in three dimensions, nonetheless. They are dispersed in space at the points of a tetrahedron. When you couple two carbons together, they can rotate freely relative to each other, so it doesn't matter where you put other atoms on those four carbon bonds, say, chlorine.
If you have a double bond between two carbons it locks them together and they can't rotate, so where you put additives on the remaining free bonds matters. If they are on the same side, they are cis-. If they are on opposite sides, trans-. Cis- and trans- are called "isomers" of each other.
Great stuff. Good night, Dr. Traynelis, wherever you are.
I'll hafta take a pass on Your link. It's been mebbe 35 years since I took organic chemistry. I actually did pretty well, because they dropped the lowest test score. Ended up with an incomplete, never took the final.
You don't use it, I completely lost all-a that, so enjoyed Your explanation a LOT.
Those bumper stickers have been around. I somehow passed PChem in 1981. I recall people had those stickers in the school parking lot. My prof was an ancient Cal Tech guy named Sly.
Mine was George Hall - top bird bander in the United States. He and my forestry prof used to spend weeks on the mountaintops of West Virginia along the north/south flyway, counting hawks, catching small birds in nets and banding them. He was as eccentric as they got.
Thanks. I told my wife that I would be terrible company in my dotage; all I would do is live in the past. Turns out to be true. Vincent J. Traynelis was my college organic teacher; I was trying to get in med school, and he beat my ass like a red-headed stepchild, but it was like being beaten with a golden whip. (I was, actually, red-headed, LOL). Damn did I learn some chemistry, and I remember a lot of it almost fifty years later! I loved it and I loved him. He died shortly thereafter from cancer. A truly great man.
The only place the word “natal” applies is prenatal medicine.
Cis applies to chemistry, not human genetics.
Stop using their language.
I swear, Orwell’s “Politics and the English Language” was prescient. Forget 1984 folks.

I've taken a number of hard science classes, but *I* sure don't have any idea. And?

I still remember the mnemonic: "marijuana eats peoples brains per hour" (methyl ethyl, propyl, butyl, pentyl, hexyl.
All I remember from P-Chem is that someone scrawled "Heisenberg may have sat here" on the inside door of the men's room stall.
Or the cranial nerves:
On old Olympus' towering tops a fat assed German vends a hops.
... or vaccinated a horse.
Or my classmate Tim's: Oh Oh Oh! To touch a fine virgin girl's vagina! Ah, heaven!

Saw a bumper sticker a few weeks ago: Honk if you passed P Chem. I heard nothing.

I'll be go-to-hell. He's still famous.

Agree, we must reject their language, because using it implies that we agree with it.
