If an extremely small amount of brain trauma or chemical inbalance can completely change a person's personality, fuck with their senses (or completely remove them) and so on, would it be plausible to say if a person were to completely destroy their head via diving head-first off of a building, between the period of contact and completely destroying the brain, could a person inside of their own mind experience an indefinite period of unimaginable agony?

To everyone else it would be over instantly, however people perceive time differently and this would be taking it to extremes

how pleb would you have to be to use a solutions manual? i want to properly get into integrals from stewart, but im struggling with definite integral stuff like utilizing sum of squares proofs to use the limit form of the Riemann sum. my prof said just to skip it but i wanted to know if it was worth going over than just doing the FTC integral methods, hence my thought of using the solutions manual to see how they did it.

So these names confuse the fuck out of me still, is reduction a gain in electrons because the loss of oxygen leaves oxygen's electrons, while oxidation is oxygen coming in and stealing those electrons?

>>8740528
Reduction is lowering the formal charge of an element

Oxidation is raising the formal charge of an element.

It's called "oxidation" because oxygen reduces the formal charge of just about anything it forms a compound with. But other elements besides oxygen can act as oxidizing agents as well.

>>8740528
Just remember "LEO GER"
its stupid as fuck but its easy to think "Lose electrons Oxidation, gain electrons reduction"

How does it gain electrons when it lowers the charge though? Our book only talks about the gain and loss of electrons, that's why this is so grindy. . ..

Are ideas energy or matter? If everything is either energy or matter, it has to be one or the other right?

Energy

You should philosophize it yourself...
>>
Ideas are a specific arrangement of matter in the form of a specific arrangement of a brain. They are a human meme, not a physical thing.

Well, if you consider ideas as neuron impulses then yes, but that doesn't really says anything special about it. You said it yourself everything is energy or matter so it's not surprising that they are energy or matter. Now fuck off.

Should all non-STEM majors be defunded and their students not be allowed to take out student loans?

I ask because my friend graduated with a degree in criminal justice. He wanted to become a cop and I assumed this was how you did it.

I was shocked to find that to join the police academy, the only requirement to join was 60 credits. You had a better chance with a bachelors, but it didn't matter which one.

I looked into other jobs such as victim advocacy, case management, etc. They again, only asked for a bachelor's didn't matter which one. What fucking use is requiring a degree if you don't care what you learned?

In fact, after some research, I found that this was the case with literally every non-STEM profession, excluding things like law and rare examples with accounting, but even those were extremely open ended.

Whole were burying our heads in books trying to retain information accounting develop problem solving skills, these people write a piss easy 500 word paper then go party. The difference between what STEM majors do I'm college and others is astounding. You want to know the number 1 hire of non-STEM majors is?

Enterprise rent a car. They require a bachelor's for their entry level, 40k position that has you working 50 hours a week at the front desk and cleaning cars.

These places know they can do this because milquetoast IQ norm is are able to take out loans for information they will never use in their life, and then are desperate to pay them back afterwards so will take any job that pays a salary, further cheapening the Bachelors degree.

Trump needs to put his foot down now and suspend all federal loans to non-STEM or law degrees.

Try dividing the numbers one through ten into two groups. Then multiply all of the numbers within each group. Is it possible for the sums to be equal? No. Why? One of the groups contains a seven, so the sum will be a multiple of seven. But there's no seven in the other group, so the sum can't be equal. Which makes seven a very lonely number.

There are an infinite number of numbers between every two numbers

Okay, so we have 1, 0.1, 0.01, 0.001, 0.0001, 0.00001, ... you can repeat this process infinitely

So, I can just divide the groups up so I have an infinite amount on both sides and get
infinity = infinity

Puzzle for you guys. There are 20 people in a room. Assuming no one was born on a leap year, what is the variance of the number of pairs people who share a birthday. To be clear, if 3 people were born on christmas and 2 people were born on st patricks, this is considered to be 4 pairs of people who share a birthday.
Variance is defined as E[X^2] - E[X]^2, where E[X] is the expected number of pairs of people who share a birthday. So finding E[X^2] and E[X], where the random variable X is the number of pairs of people who share a birthday, yields the desired quantity.

I know posting this won't lead to any major scientific breakthroughs or even yield any sort of breakthrough at all but... It just upsets me that people like him can get away with spreading such falsehoods. Because let's face it, not *everyone* studies this stuff enough to know that he's full of shit. And it seems as though a lot of those people are believing the sort of stuff he says because it "sounds scientific". He has a video in which he claims the Aether to exist, and calls light "a coaxial circuit consisting of longitudinal compression and rarefaction along with transverse electrical and magnetic divergences" (paraphrased for corrected spelling and use of grammar). He *also* keeps referring to "dielectricity" which isn't a force at all, he's just bastardizing the term "dielectric".

Am I in the wrong for thinking that's a really fucking bad attitude to have when learning maths?
Like, sure, once you know how to do it by hand save time by having the computer do it, but she insists I not do any of it. Just punch in the equation to a computer.

Or is she just a lazy teacher?

Scientifically speaking, what determined the parameters of your genetic lineage, i.e what phenomena or entity or variable determined under which species/ancestry you would be born to? As opposed to some other genetic lineage. etc.

Was it random chance or the big bang itself or something prior?
