>be high IQ (tested) (adult)
>no internal monologue unless I literally talk to myself since my head feels pretty much empty most of the time, except there's always some music playing like a jukebox
>need external stimuli (like playing chess) to actually start thinking, but without even more outside pressure (like very little time left, nearing deadline, etc.) I barely even get going, do nothing but vaguely worry about it mostly
>not even sure how I manage to write essays and shit, as I write *before* verbalizing/visualizing/anticipating ideas
>lethargic and slow as fuck, lost in thought, melancholy except I don't really think, just space out
>feel absolutely retarded, only have IQ/"accomplishments" and reassuring friends to cope
>uppers like vyvanse, ritalin, etc. didn't "unlock" anything, just made me restless
>weed doesn't affect me much
>low dose of psilocybin removed my "filter" and inhibition somewhat but ultimately didn't change much
Is it just autism or something else?

geometric proof that 0.9999.. =/= 1

No.13752234 ViewReplyOriginalReport
let's call a line with infinity points the unit line, with length 1. if a line has 2 length, it has 2x more points than the unit line so it has 2infinity points and so on. since this proportionality holds, we can say that the length of a line is the amount of points it has devided by infinity. the length of a line with infinity - 1 points would be (infinity - 1)/infinity = 1 - 1/infinity = 1 - 0.000..1 = 0.99999999... therefore if 0.9999... = 1 the unit line and the line with one less point must be the same length. but for that to be true, every point would need to have a length of 0. however, if every point had a length of 0 then every line would have a length of 0, since 0 * infinity = 0, which is obviously not true, anyone who has seen a line knows this is not true. so the only possibility is that 0.9999... =/= 1.

To what extent can electrical engineering theory (like what you'd find in 2nd/3rd year EE classes) be self-taught?

I'm not looking to get a job doing this, just want to learn the material for fun. Is it like math where simply working through the usual textbooks suffices?

How random is our Universe?

No.13750582 ViewReplyOriginalReport
Guys I was just wondering about mathematical randomness in quantum mechanics. I'd like to know your positions on this. The anthropic principle is often touted as a way to justify our existence in a universe, familiar towards life. However, I'd like to go one step further and take quantum randomness seriously. Let's say we apply that the collapse of the wavefunction from the beginning to the present moment has always been completely random. By sheer probability one can show that even this universe, with all the "correct" laws, can outnumber the number of states that are hostile to life versus those that are conducive to life, let alone big organizations, the internet, etc. Do you think that quantum mechanics may have a hidden bias that we are not seeing?
