And any possible explanations on the correlation of rap preference and lower IQ?

No need for a white paper, it's plainly obvious that listening to rap reduces intelligence.

was it rap music that lowered IQ in black or black being lowest IQ race guarantees they can only make trash rap music?

If our skin is meant to have a delicate microbiome of bacteria and yeasts, that basically get washed off with exposure to water and resets the skin to a ground zero that one must build up all over again, are we actually evolved to never wash our skin with water, let alone any form of surfactant? Or even to allow dust and dirt to do the work of exfoliating residues off, much like every other mammal that only takes dust baths?

They might be smelly but their hair is usually fully moisturized/oiled and the best looking on the planet, and id imagine their skin isn't far behind. Is this due to their averse showering habits?

you think cavemen ever got rained on or waded through bodies of water?
>>
>>16195094
They did, and then they had the month or so of rebuilding the surface microbiome, where the modern man is expected to shower daily.
They also lived the much more natural lives that our bodies were evolved to live, replete with dust to add nitrates, heavily mineralized water, and probably even some skin parasites that our bodies are evolved to regulate with.
Showering (not even immersing) in treated chlorinated city water and rubbing formulated chemicals all over is probably completely foreign to our skin and does nothing for it

The confusion here is semantic. Is you multiply 1 by 1 then you get one, but if you multiply 1 for 1 you get 2. Terryology is correct, but it complements multiplications. It doesn't replace them.

Is math invented or discovered?

Are mathematical definitions invented or discovered?
Are mathematical theorems/results invented or discovered?
>>
It's a language humans invented to describe the things we discovered
>>
It's pure invention (either by conscious effort or biological evolution). It acts as a translator who sits between our brain to what we see in the universe. It's a funnel that captures natural observation and brings it to us in a digestible form.

"Discovered" implies that we are pulling something out of these systems that in itself provides understanding without a pre-existing mathematical context to filter it through. I think for many people it can feel discovered, because our brain naturally has rudimentary mathematics built-in by way of pattern recognition. When we see some phenomena occur, the brain naturally sees the pattern, processes it, and then projects the outcome onto the object and says "the math was there all along". That's fine for all practical purposes, but philosophically it's a bit of a trap.

You wouldn't say the color green was "discovered". It's the way we describe a specific wavelength of light. The "experience of green" is an abstraction and means nothing without the brain running some process on it. The wavelength exists, but we've obviously tacked on a bunch of shit after the fact to help facilitate understanding.
>>
Discovered for sure. To think about this question we need to ask what even is mathematics? For example, the fact that the square of the hypotenuse of a right triangle is always equal to the sum of the squares of the other sides is a mathematical fact. How does it make sense to say that some guy just came up with that (invented it)? It's something that just exists in nature (perhaps not literally in nature, I'm using the word 'nature' very loosely here) and someone had to actually discover that the said equality is true. Even if there are aliens out there, the aliens would have discovered the exact same thing.
>>
>>16195057
I think the "aliens would have discovered the exact same thing" makes a lot of assumptions. Ultimately, we have to filter the observations through our own uniquely-human brains before we start slapping mathematics onto it. That initial filter is completely unavoidable and we don't really have any other context to compare to (that we currently know of).

Things we take for granted as mathematical facts could be completely outside their cognitive framework or be considered esoteric, unhelpful nonsense. If you viewed the universe in a completely alien way, you would probably come up with other mechanisms. Something like basic trigonometry as we understand it relies on having eyes, conceptualizing 2D planes, etc. It's kind of a case of "it's correct because it slots into our cognitive framework and has practical applications". However, I do think that if we were sent back to the stone age and had our memories wiped, that humanity would re-invent the exact same mathematical facts.

What happened? I thought we were the science.

He idiot....they still need fertilizer. That's how I know you've never grown a vegetable. Grow a tomato in the garden and never fertilize it. Now grow an identical tomato next to it and feed it as much salt based fertilizer as it can handle without damage. Now weigh the resulting produce at the end of the season and see which tomato plant yields more. Spoiler the one you fertilize. So yes the nitrogen fixing will be more efficient but only a fool would "leave money on the table" and purposefully yield less per acre when a simple application of cheap nitrogen results in anywhere from 20-100% increase in end product aka a 20-100% increase in profits. If you use your brain and simple logic things like the above will not need to be explained to you, it will just come naturally.

The other book I found has little applications, but detailed solutions to every problem. This second book is called The How and Why of One Variable Calculus.

I use a 1.0mm tippen pen for my daily notes since 0.7mms are the goyest of the goy calibers for writing, its literally the minimum possible amount of graphite for the largest possible userbase
>Your tip broke? Just strap another one goy, that'll be .50$
>Your writing looks like shit since you are the child of two doctors? Well learn to write like a robot goy!
Meanwhile 1.0 technical drawing chads are writing with sturdy tips and readable words, now if the jews in charge of pen tips manufacturing were to be "persuaded" to drop their antics and just produce 1.0 tips, pens and pencils. I wouldn't have to pay a specific premium just because 1.0 is used less, people would produce less wasted tips and writing would be easier
TL;DR:
I hate 0.7 mm tips and would like 1.0 mms to be the standard for writing

Exxon's science on global warming changed between 1977 and the 1990s. They thought global warming was real and then they realized that they were wrong about it.
Science changes, its called learning. How come you're too dumb to evolve mentally the way the scientists at Exxon can? Why do you still believe in disproved 50 year old theories?

it's a feature. it's like to join the communist party, you have to be corrupt so they have something over you and know they can control you.
in some fields like social sciences or some fake transcattle research etc..., in order to progress the academia ladder, you have to join the cult and commit some fraud but not so obvious and not too stupid so that everyone know you did some fraud but nobody outside the cult bother ratting you out because it takes efforts. however, the people in the cult now know they have control over you and can trust you to never betray their tribe.
