I always thought it like this: the first square is being squished, squeezed, by the vector of the forces that are the curvy lines following it. The result of when you squeeze a square is it will look like the final picture.
I never really understood what was happening on the second and third lines though.

Ohhhh i get it.

Line by line.
Line 1. Square. Ok. Then there's those two curvy lines. Spin the whole second figure 90 degrees to the right and invert each of the lines. Combine them with the square and you get the last line.

Line 2. The square again. Ok. Now the curvy lines. Spin them by 90 degrees, to the right. Now invert them, each of the lines. Combine them with the square and you get the third figure.
Line 3. The square. Ok. The curvy lines. Spin them by 90 degrees to the right. You'll get some kind of U like this: )_(. Invert each of the lines. You'll get an U that looks more like (_). Combine them with the square. You'll get D.

Define genius level IQ op.

40 points and up from the average is considered genius. If the average is 100 then 140 iq is genius. If the average is 85 then 125 iq is genius.

A better question to ask is if there is a meaningful difference between 125 iq and 140 iq. Take into consideration that +120 (125 in some scales) is post-grad intelligence.

Being a NEET is only valuable if you use your "7 day weekend" to do pure mathematics. As you attempt to do this you will soon realize that you need a roof over your head and roasties to clean your balls, which cost money. Then you go to the nearest university and tell them "Please give money. I will do mathematics for you and maybe teach some of it when I feel like it" and then they give you a roof to put over your head and money to pay for roasties and then life is solved.

But if you can live with your mom like Papa Perelman then go for it. It is just that not everyone has that benefit.

Sorry that you're too much of a brainlet to understand that the best method of understanding the actual operation of neuronal circuitry involving millions of neurons is to introduce a stimulus and measure the reaction to it. I.e. behaviour. Its the same principle behind artificial neural networks: you visualize the layers by a feed-forward step from an input. Of course this is too basic for mathematicians, so instead they will shoehorn the data into algrebraic geometry or category theory, make some unfalsifiable claims, and pat each other on the back.

Is an intellectual goal ever worth the bodily harm that results being almost entirely sedentary in order to pursue it?

Medfag brainlet here. I am studying for the USMLE Step 1 exam a.k.a. "the boards," which will essentially decide my entire career. If you score high enough, you can match into any specialty at big-name research hospitals. If you fuck up, you end up as a family medicine doctor in bumfuck North Dakota. Unlike other standardized tests, this one is based almost entirely on content knowledge, not critical thinking , so your score is more or less directly dependant on your memory and how much time you put in. Unlike my naive classmates who still attend lecture and cling on to the idea that medicine requires critical thinking, I have been spending 12 hour days in the library for the past 5 months memorizing as much as I possibly can. I have 10 more months until the big exam. I know this is the only way to get to the big dick score score of my dreams, but I am worried about the toll it's taking on my body. They say sitting is the new smoking. What keeps me going is the idea that it's just temporary.
