I think you can represent the language by
a^(j+k) b^(j) c^(k) , but Im having trouble writing that using the pumping length, maybe

a^(n+j) b^(n) c^(j)
where n >= p and j >= p

Trying to whistle. Don't tell me you never did this? Try it without the grass, if you do it properly it sounds like an owl. If you put a piece of grass and do it properly, sounds like a whistle.
>>
>>9248329
>>9248343
It's really loud, and if you do the right thing with your hands and mouth, making the sound start really high and drop quickly you can draw in a horny male elk during rut season. Actually, after listening to some elk noises on youtube it might not matter what noise you make with the grass blade. If you actually do call in a horny male elk, be aware they can get close to 1000 lbs. If it wants you it will have you. It also might get mad you're not a lady elk like military guys do when they find out they brought home a ladyboy.

"Soon" is a relative term but I do think hitting max level does happen quite soon compared to what most people would think. Not saying we are getting close to max currently but that when we get AI it won't take that long because research will be super fast after that.

There maybe some millions of scientists and engineers on this planet but most don't do research. The ones that do, don't do it 24/7. I don't know how many research-hours are being performed but I bet it's way lower than what a billion or a trillion AIs would be accomplishing. Many orders of magnitude difference.

Hello /sci/, chemical engineering major here. Currently in organic chemistry 2 and really liking it, I'm surprised at how bad my peers are doing around me and it gives me some hope that I'm doing the right thing.

Anyways, I want to know more of the "why" the reactions are happening than just what the class offers. It briefly mentions inductance, shielding, resonance etc but never goes super in depth, it still comes down to memorizing mostly. I was wondering if you guys knew relatively easy to consume media or even mild literature to get a better grasp on the "why", like why fluorine is the most electronegative element yet not a strong acid, how nucleus size affects the chemistry, every little foundational rule that governs how atoms behave. Not necessarily things I need to know for the class, but things around the class that will help the subject become even more intuitive. I'm just looking for things to watch or read in my free time that don't make me feel like I'm reading a college textbook, that I can relax to, but still learn from. I like Nurdrage, NileRed and a couple other youtubers, but I haven't seen anything like 3blue1brown is to calculus, that really helps reinforce the "why" things work as they do.

Any suggestions to help reinforce the subject?
>>
>>9248658
>>every little foundational rule that governs how atoms behave.
we don't know all of them. Things just work cause they do.
>>
>>9248658

Think of everything as the movement of electrons to their lowest energy configuration. Don't think of atoms as the hexagons you draw, but as the electron cloud. Then it becomes much easier to visualize the flow of electrons and how bonds will break and reform.

As for texts, I recommend advanced organic chemistry by Carey and Sundberg

Got through Organic 1 & 2, acing them, when the vast majority of the class either failed or just took the C/D

All I need was read, do reactions, read, memorize. Like you said, just look over mechanisms...so...many...mechanisms

best website for newest science news?
3 replies omitted. Click here to view.

>>9247892
A lot of bullshit gets posted in every single one but at least it's immediately obvious after actually reading them if they're on to something. Every single actual news site will usually interpret the papers in their own way, so you will have to search for the papers to get the facts anyway.

It's actually really frustrating to stay informed if you go for general science without specializing.

Brainlet here,
ok, circle area is pretty easy, good approximation with a many sided regular polygon, and actual area by dividing it up into pieces and shit and summing all of it up.
the sphere's volume and area seem suspicious. What the hell does a cone/cylinder (forgot which) have to do with it?
>>
>>9249027
Just use double or triple integration. I don't remember any connection to a cone or cylinder but it is not unnatural for there to be one. All three are made up by stacking a bunch of circles on top of each other.
