Probably should have made a fortune manufacturing meth instead of the grind.

Heisenberg? Is that you?

“ Chemistry was just enormous amounts of memorization. Why does Carbon react with Oxygen and not NItrogen?”

Once you get to Physical Chemistry, you get heavily into the calculus of probability, all about determining reactivity and predicted reactions. So it definitely goes far beyond memorization.

Then it's taught wrong.

Start with the physics, and move back to observation. That was a complaint I had about physics, they first taught us the equations THEN they taught us how to derive them. I was so pissed off when I realized I didn't have to memorize any of it.

I hate memorization. I have to understand how it works, it's not enough to know it works.

Is your career related to organic chemistry now?

Please, do not confuse me with the masses. I am a rentier now.

Spontaneity is a function of initial energy differnce plus porpoensity to seek a more random (disordered) state of being....

That's why my room is a mess, but has yet to spontaneously combust

Most chemists older than 50 incl me became interested in chemistry because they were blowing stuff up as kids or teenagers.

Lol, I did that too. In high school chem I realized that I could dissolve and mix the lead nitrate and potassium iodide that I had in my chemistry kit at home to create potassium nitrate, a component of gunpowder. And it worked, I made gunpowder by mixing in charcoal and sulfer. Then I had horribly orange lead iodide as a byproduct which I threw out hoping my parents wouldn't find it. Probably poisoned some landfill, though it wasn't a large quantity.

I loved chemistry in high school and did very well. Had a great chem teacher who later went insane and murdered the superintendent:

Still, he was a really great teacher.

We could buy potassium nitrate as fertilizer so no need to make it. After black powder we graduated to making acetone peroxide (of shoe bomber fame). That was dangerous, a friend of mine has a scar on side of face...my best success tho was mixing Aluminum powder with potassium permanganate. That goes off with a huge bright flash.
All of that is strictly verboten these days. No wonder kids are afraid of and bored by chemistry.

Reparations porn.

Lottery porn.

Prof only gave one one A per class.

I found the sciences that I did take, and retained almost nothing, to always be that way. It was weird. Our top students in high school would be thrilled with a B in Chem. Chem and biology teachers are strange animals from my small/short experience with taking them. Sciences were not my jam.

My Chem teacher would do a martial arts "act" or whatever you'd call it at the end of classes on Fridays. He'd also blow shit up. He frankly did some pretty reckless stuff in a school setting. It was a fun/bad class. I took the C and in hindsight, who gave a shit. I used or needed nothing from those classes. Was useless knowledge for me, so I emptied that from the brain bank.
