I can't wrap my head around plate tectonics. Some plates are moving very fast while others are moving slow, without affecting the speed of the plates they are in contact with. One plate can split into two like how the arabian plate came out of africa... somehow. Pieces of land can randomly leave a plate and go to another plate like how madagascar seperated from india. New tectonic plates can appear without an obvious mechanism and that existing plates can be destroyed by subduction despite the fact they are also rifting away and expanding at other plate boundaries. And the idea that the ground is like a log of wood floating in a bathtub

How can plate tectonics be learned?

Is there something you should NEVER EVER consume because it would interact with the HCl in your stomach (or other of the substances there) and basically melt you from the inside? By the time you notice something's off it's already too late. Consider that we have inner mucus to avoid getting digested by our own HCl already. Zn + 2 HCl ZnCl2 + H2 would be uncomfortable to say the least but wouldn't be overly destructive (probably).

the obvious answer is fluoride
it's fine in pretty tiny amounts (hence its use for dental health), but it will react to form hydrofluoric acid, and that is absolutely not something you want inside of you. especially since it is capable of seeping through body tissue

It would help if you could give examples of problems you failed to solve, and where in the process your classmates got ahead of you.

I don't bring this up for any retarded political reason, I believe that homosexuality(or rather, "queerness") became prevalent among humans "intentionally" due to my noticing of the influence of birth order and other inherent traits which are correlated with the "queer" state, and wondered what role this might play, if any.

Now, I'm not sure if bisexuals were lumped in with homosexuals for this stat, which would warp things quite a bit(most pedophiles would describe themselves as bisexual if pressed), but in any case, I know that *actual* pedophilia is 11 times more common among male-attracted men than their straight counterparts, making about 22% of queer men pedophilic (this was determined with phallometric testing).

I currently think homosexuality served a similar purpose to menopause in that it redirects energy that might otherwise be used to reproduce towards the end of helping their genetic adjacents(children, siblings) survive and reproduce due to that becoming more effecient(queerness is most common among the youngest child in a family). Perhaps giving a sexual motivation for protecting the most vulnerable members of the group allowed these people to fulfill their role most effectively?

Any interesting thoughts to add? Please don't just sperg out at the numbers -_-

ITT We have two types.
Those who are simply retarded and those who post stuff which is so fucking retarded it actually takes someone who is quite clever to think of it.

If you understood what I just said you are quite clever. If you did not then you are retarded.

Sup academics.

What is the best way you have personally cheated in higher education, or what is the best cheating story you have? Paraphrasing existing work with Quillbot and passing it of as your own? Saving answers on your T53 and loading macros during proctored exams? Rewriting ChatGPT code and passing it off as your own?

>blah blah you didn't earn your degree

Oh well

Higher education only. No one cares about high school.

What the actual fuck is their problem
>>
>>16869658
This. To emulate the behavior of d/(dx) using the total derivative just requires the restriction dx = 1, dy = 0, dz =0, etc.

If you really must use the fraction operator at least write it properly as (dx)\d
Writing d/(dx) gets the chain rule wrong when changing variables.
d/(dx) becomes d/(dy)*(1/g'(y)) = -g''/g'^2 + (1/g')d/(dy) after substitution x = g(y)
(dx)\d becomes (1/g')*((dy)\d) which is the right answer.

Full blown schizo here. You just see things that are so unbelievable but so elegant and simple and it all makes so much fucking sense. Some of the basics I figured out on my own like the colour of different stars defining the personality so you say of what different life might be like in their solar systems but when you see what's out there it's just so mindblowing there's no limit of words I can say and you'd understand nothing from them. I've been posting my schizo nonsense lately but nobody seems to notice. Like if I tell you there are insectoid robots from outer space that turn themselves into organic life you're just gonna say I'm retarded, but literally the only cool thing about my life are my hallucinations and I know what I see is true. I don't think anyone can become schizo, but my method was basically semen retention, extended periods of not sleeping and a fuckton of weed. Can't just sit around getting high though, you need to have a dynamic lifestlye. You'll meet people and things will line up if all you want is knowledge. Reality is so far beyond what our sci-fi has imagined, and some of our sci-fi wasn't merely imagined. You just wouldn't believe, and nor would I if I hadn't seen some of these things myself. I wish you well.
