Why would they? Modern ones are optical, very little interference.
Even for normal wires you just have to shield the from each other, like in any other system where interference can happen.

More bonds your body can take advantage of in fat and carbs, so typically they're more Calorie dense (more energy per unit volume). If your body doesnt use the energy, it stores it, making you fat. Being overweight is bad for you for many reasons (Google is your friend here). Hence the "crusade" against fat and weight gain.

Cholesterol is a different story. Also a type of far, but your body uses it differently

Nothing, the keypoint is if an identical copy of you is sitll you.
From the point of view of your copy they would also think they were the same person and they would also perceive no time as having passed.
From the same argument given an infinite time you could construct an a copy of you which would have disjointed memories, different orders of memories, etc and their perception would change. In the end your consciouness in that scenario isn't coming from anything outside, because all these bodies are different and not tied to you, yet they all think they are you.

Absolute pseud take,
you can't just say physics or quantum science explains your brain matter until you explain consciousness and where it lays in, what happens if you replace half of atoms in your brain? what if you steadily replace all of them with exact shape and form? Could you clone yourself by only replicating only half of your body in 1:1 form? Where would your consciousness be at then? Would you feel the transition? Which one would be "real you"?

Runs as in some genes give you a higher chance to have depression. Yes.

Lack of a strong family culture and a mid clear goal, which is a constant in the western world, makes huwhites more prone to depression as well.

Depression is real and its mostly caused by an imbalance of chemicals in your brain. Nothing to be ashamed of, see a psychiatrist and get that treated.
A good rule of thumb to know if you have depression is if you can't find a reason as to why you're feeling sad over long periods of time.
If you're sad/sluggish BC you don't have a purpose, your don't have a gf, or smth similar then it's not depression.

Inverse Functions

Anonymous Thu 07 Apr 07:55:28 2022 No.14371417 View Reply Original Report

Quoted By:

It seems as though there exists an inverse function for every function there is. Some people say the inverse function of a non-injective is useless, but you could set f(a) equal to f(b), and find all the instances when f(a) equals f(b), and use that to figure out all the possible x values for a particular y value. For example, the inverse function of x^2 is sqrt(x). If you set f(a) equal to f(b), you find that a can be equal to either b or -b, and vice-versa. Tell me if I'm wrong.

For non-injective functions, there exist multiple inverses. Take the function f(x) equals | x + 4 | . It has two inverse functions, f^-1(x) equals x - 4 and f^-1(x) equals -x - 4 . They can be expressed by a piecewise function. Let's take f(-2) and f(-6). They both map to 2. If we put 2 in place of x for the first function, we get 2 - 4 = -2 , and if we place 2 in place of x for the second function, we get -2 - 4 = -6 .

Quoted By: >>14371126 >>14372736

Why is IQ useful? Why does it represent more than just a score on a test? Because it correlates quite well with certain aspects of life, mostly academic (GPA etc) and financial (income etc), as well as being reasonably effective in testing for retardation. If IQ didn't correlate so well with any of these things, then it would be less relevant as a statistic. Given that the correlation of IQ with academic performance and career success is far worse towards the higher end, it is not really worth noting or comparing your scores so long as they are around 2SD or higher.

You could absolutely do more than 7 AR1s. From this infographic I calculated an AR1 size of about 1.72m diameter. NSF calculated about a 1.75m diameter from known variables and working backwards with the math. You could do 9 engines at the very least. More if you start doing more complicated packing techniques like 3 or 4 central engines, and some engines protruding off of the side with aeroskirts to protect them like how the Saturn V did it
