What does /sci/ think of Category Theory? I started getting into the subject few days ago and really liked it. Kind of a sweet and gentle. Like those subjects in HS that didn't really matter but professor tried really hard and you felt sorry for it. Same thing here, but without pitty

Is there more to category theory than babby’s first composition?

Exactly what I said. It looks naive at first. Some things that i didn't bother understanding in algebra, became much simpler now.

Useless. Set Theory is already perfect.

An asteroid is a small rocky body orbiting the sun. Large numbers of these, ranging enormously in size, are found between the orbits of Mars and Jupiter, though some have more eccentric orbits.

A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements. The Sun is the closest star to Earth.

What are your views on the work of Dr. Sigmund Freud?

Do you agree with his theory about the unconscious mind, psychosexual development and life/death drives?

If you are 'naive' (have no tolerance) wrt some antispychotics, they will knock you out.
Geodon, thorazine, that kind of thing.

I'd bet that some of the drugs used to put people under for surgery - Brevital - would work, and fast at a proper dose.

Can confirm.
I have to cut my pills in half after a long absense, and they still take me out for most pf the next day

If you had access to unlimited human experimentation could a cure for cancer be developed?

Obviously one could breed cancer resistant humans, but I was thinking more of a treatment.

Is it feasible assuming no ethical implications. Do as you will.
