What would happen if you traveled back in time and killed your grandfather? If he dies yuo dont even exist ever, so you cannot kill him.
>>8527774
You can't travel back in time.

Different timelines i guess

OP, would you like the red pill or the blue one?
can anyone with an above average iq who has the money and is willing to work hard capable of getting a PhD?
yes
really you only need two of them
>>8527667
>above average iq
So, around 45% of the world is above average IQ, OP
>money
Well duh, how will you pay for the PhD?
>willing to work hard
You obviously do this and everyone does it as well but it depends on how fast you can learn is the actual difference
>>8527762
what are you getting at?
what I was really asking in the OP i guess is how special do you have to be to earn a PhD?
Are the Feynman lectures on physics a good place to start for someone who has studies all the hs physics courses but wants to brush up his skills and maybel learn something new? Or are they outdated? And if so, what would you recommend?
they deal with stuff that hasn't changed since they were written so it's OK. not outdated
i dont like the way it is structured tho
>>8527631
>all the hs physics courses
"All"? So you took algebra based physics, then took honors algebra freshman physics, and then took AP premed watered down physics?

You assume I live in USA, I don't. Your pre uni school system sucks, I know.
So I failed Calc 1 last year in College because I was a piece of shit that didn't go to class and missed exams. I knew the actual material since I took Calc 1 in highschool, but now my college won't let me reapply for Calc 1 unless I retake the placement test. Does anyone have some good pre-calc/calc1 books for review?
>>8527626
lol
patrickjmt.com has a fuck ton of video lectures for (self admitted) pieces of shit like you
beyond that, if you're dead set on conventional textbooks, go to bookzz.org and do a keyword search
Stewart's books are serviceable, assuming you need calc but aren't a math major

I want to become programming literate enough to A) land a comfy job hacking at Blockchain/Machine learning meme tech and B) eventually hack together my own projects in the future as a hobby. What is the best way to go about achieving these goals? Would the education path (Community College then 4 year school) be the best way, or self learning and getting some sort of credential?
I don't care enough to learn everything there is to learn about computers... just enough to hack shit together and know when I need other people to pick up my slack.
>>8527522
>comfy job hacking at Blockchain/Machine learning meme tech
lol

I was just coming in to chuckle at this too, gr8 laffs OP

If you think albegra/statistics is easy then go learn by yourself

Could Heisenberg's Uncertainty Principle be resolved if we had better tools to measure electrons?
>>8527495
But then we wouldn't have free will asshole
>>8527495
Literature says no
I say yes
>>8527495
I can't even imagine what "better tools" would be able to do that
There are quantum mechanical reasons for the inability to measure electrons, if I recall correctly the foremost explanation is that at a quantum level the electron reciprocates with its observer somehow, which changes its momentum or position.
The double slit experiment is really fascinating and illustrates this better than I can.
Alright, fellows. I'm in a deep one. I need to find the turning points (points where [math] \dot{r} = 0 [/math] ) of pic related.
The result should be given by the equation in pic, but the one I'm getting has minus at the second term in the second parenthesis.
Can anybody tell me where am I wrong?
>>8527447
Also, to use the initial conditions (r0, v0) to express the constants arising from the integrals of motion.
Appreciate your help
>>8527447
>has minus
I meant to say that it has plus in the second term of the second parenthesis.

Can someone explain to me how the sum of an infinite number of zeros can equal not zero.
I understand that we can do a lot of cool things by assuming that it doesn't sum to zero, but it seems apparent that the limit of pic related would be zero.
it is zero.
it's the sequence:{0,0,0,0,0...} which converges to zero
>>8527339
Why wouldn't it be zero? What is happening in this board? Is /B/ raiding us?
>>8527348
>>8527371
Doesn't integration require the sum of an infinite number of zeros not to equal zero, though. If you imagine integration as a Riemann Sum as the area of the box approaches zero, then you're just summing a bunch of zeros together and getting a non-zero number.
Or, since I'm more familiar with statistics, we know that, given a continuous distribution, the probability of getting any one number in particular is 0%, but the probability of getting a range of scores is non-zero. Thereby, summing an infinite number of zero probability events, gives you a non-zero probability.
I find it so strange that no one is talking about this, this might seriously be a beginning to a new era of mankind.
Can we connect logical thinking to our reward center? Would you do it?

Suppose that there exists infinite series that converges conditionally in classic space R of real numbers. Riemann series theorem states that I can rearrange elements of this series to get what ever real number I want.
If we look at R as algebraic structure, what is the main property that gives us this theorem?
What does group theory says about using operator infinite number of time?
group structures don't allow for infinitely applied operators
it's a purely sequential property
>>8526979
>If we look at R as algebraic structure, what is the main property that gives us this theorem?
The least upper bound property, and how any bounded closed set is compact. These properties form the basis for the proof that R is complete.
Monty Hall is psychological bullshit
After your first decision, the host will ALWAYS open a goat door. There will ALWAYS be one goat and one car remaining. You have no impact on this outcome no matter which door you pick. It will always end with the same result. The first decision has zero relevance.
The first decision exists purely to act as a mind game to make you consider additional variables in your second decision which ultimately hold no meaning. Monty wants you to hold a sentimental value towards one door over another, to frame the decision as 'stay' or 'switch'. But that's purely psychological.
When framing the decision as "stay" or "switch" you get 1/3 to 2/3. But when you frame the exact same decision as an isolated event, an individual choice between two doors - which is exactly what it is since your first decision made no impact on the outcome - it's unarguably 50/50
This is why abstract probability is just bullshit pseudoscience easily conflated by irrelevant data
Prove me wrong (you can't)
>>8526737
but each time you switch doors the average amount approaches 2/3rds of the time, this can be demonstrated experimentally. http://math.ucsd.edu/~crypto/cgi-bin/MontyKnows/
Surely if you deny the abstract theory, you at least support empirical evidence?
>>8526743
https://math.ucsd.edu/~crypto/Monty/monty.html oops broken link
>>8526743
You're missing the point anon
That experiment is still with framing the decision as "stay" or "switch", which is dependent on whatever initial decision you made
But your initial decision is meaningless. The outcome is always identical (one goat door opened). It serves no purpose for setting up the second decision besides framing it to be about some arbitrary attachment
Run the exact same experiment as "pick door 1 or 2" rather than "stay or switch" which is relative to having picked one beforehand in an old decision that had no impact. It will be 50/50

Lets say someone shot a giant space laser at the yellowstone caldera and burned a whole through the rock into the magma chamber, could it set off the volcano?
That's a solid maybe.

Why not just dump a bunch of thermite down it?

Depression is not a mental disorder, it's a rational response to having a shit life
So how do You convince your depressed mate that?
>>8526413
Then it's not depression.
Depression is being chronically sad when you should not be. Being sad when your life is shit is not depression.
When you're successful, have a loving gf you bone every night, a nice house and car, and a good career and are so sad you can't get out of bed and want to blow your brains out, that's depression.
>>8526418
But You are stating generic things. There can be other things in that Said persons Life. Things they want to be different, which they deem as depression, since they havent been true to Themselves about what they seek to change. For that Said person: he could be gay, only keeping that gf for his image to friends and family, while going to his job, to Pay for shit he Dont want. Like the House etc.
