Suppose it was possible to attach a rope from the Earth to a space station.

Would it be possible to climb said rope from the ground into outer space? I have a vague understanding of rockets needing to 'punch' through the atmosphere in order to reach outer space, but that involves flinging hundreds of tonnes of metal from Earth's gravity. If it's just a guy, climbing a rope, is it theoretically possible to slowly pass through the atmosphere?

Assume also that our climber is a beast and can also carry any oxygen/food/spacesuit/whatever is needed for survival.

Pic included for clarity.

Yes, it's possible, assuming all the many assumptions needed.

No, there's nothing to "punch through". Real life isn't Spaceballs.

Also all of the other stuff you believe is wrong.

space station would have its orbit fucked by you climbing up it and without help it would fall

it would need to burn fuel to keep itself aligned. Fuel that would be better spent just launching your dumb ass on a new rocket

Why does the wave function only collapse in one specific way? It could collapse in many different ways, but why does it only collapse the way it does, out of so many other possibilities?

look up transactional qm, penrose interpretation, GRW, debroglie-bohm, etc, read them, then come back.

no one knows, it's not relevant day-to-day qm anyway, it is retarded philosophy.

despite what many say, MWI is not that bulletproof (preferred basis problem, probability, the paradoxes caused by the equal reality of all parts of the W.F, etc). It is strong in some respects, but overall it seems some form of objective collapse interpretation will win eventually (not until we figure out gravity though). If Penrose's conception of gravity is corrected, his interpretation will hold and he has devised some tests for it (they are just hard and expensive, and no one really cares).

Old school copenhagen (ie Von Neummann) is pretty dumb, but the reformulations of it (there is no single C.I.) make more sense. Also, modern C.I. thinks the wavefunction is a good descriptor/approxiamation, it is not the lowest level of reality. Recent discoveries suggest this is probably true, which takes away a tiny bit from the MWI.

Just read about it though, it's actually pretty interesting.

Also, not sure if this is true, but I have noticed a lot of overlap between sweaty euphoric neckbeards and staunch MWI supporters. I can see why some like the MWI for its simplicity, but the really staunch MWI fanboys that hate other interpretations are almost always neckbeards or groupies for Tegmark and Deutsch.

Don't be so verbose. Others have phrased it far more succinctly and eloquently before:

in the most unreasonable, anecdotal and baseless way, i believe a lot of it comes down to talent. i have a friend who is studying complex university level math, in his words most of the time he can reach the solution before he knows exactly why and what his thoughts leading up to it were.

for me as a grown pretentious man-child of 22 years i have severe problems even comprehending basic high school math, if i get it explained to me i still don't understand the reasoning. i didn't go to special-ed or whatever and i passed all my high school math and did ok in most subjects other than math.

i have interest in some scientific fields which obviously requires more math, can i overcome this borderline retardation? and what is it caused by? too little fish in my diet in infant years? is there such a thing as dyslexia but with numbers instead?

Yes.

Leave high school and take college courses in math. High school education in math (in the US) is so fucking retardedly structured it's unbelievable. It wasn't until uni that I developed a legitimate understanding of the material.

If you are out of uni, find a good textbook on the subject you want to learn. Go through chapter by chapter. Make sure you aren't skipping essential subjects. I believe curriculum typically goes algebra, pre calc (essentially algebra), calc, multi variable, DiffyQs, linear algebra, etc.

Instead of calculating, which are brainless alghoritms that computers always do better, you need to understand the basic concepts. and purpose of why they are invented, and what problems they are solved.

To know that you need to read any math history book. Like this https://archive.org/details/AHistoryOfMathematics

There are different processes at work inside our minds when we think in certain ways. Expressions as in societal interaction, fact retention, logical processes, abstract inductive reasoning, empathy, all of these are really important and generally a person is just better at one than others. It's actually rare to non-existent for one person to excel at most or all. If you're not great at one, don't sweat it, it probably just means you're really adept at another and you're not fully channeling it.

>other person is alright but unsure of herself and slow
>I am able to grasp and apply this stuff off quickly, but it takes forever to get my work done because I effectively have to tutor everyone in group and walk them through it

This is extremely frustrating. I can't decide if it's good or bad for me, on one hand it's definitely holding me back from stuff I want to pay more attention to personally, but on the other hand it's good because maybe it tests and reinforces my understanding by having to figure out how to show it to other people after I've just barely learned it.

Have any of you had an experience like this?

-Try to help your peers understand the math the best you can and try not to make their weakness yours
-Talk to your teacher about changing groups or separating yourself altogether

Don't sweat it. High school teachers are used to accommodating autistic children.

We choose to go to Mars in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.

It's so strange to be going trough 1st grade to high school math with khanacademy to prep for uni.
It's been 5 years since i went to school and i also find all these small holes in my math knowledge which is interesting.

Is anyone else prepping for the upcoming semester?

i did just what you did. it helps a lot, also its interesting to see how easy all this stuff is when you are older. so why even learn it over 8 years as a kid. when you can do the same over 3 months as a grownup.
