Can someone explain why the anticausal form of a geometric series with |R|>1 is the same as the causal geometric series with |R|<1? This is completely unintuitive.

I'm talking about this shit:

what exactly are you confused by on that page?
>>
>>9166688
I just realized I misphrased my ask. I meant: why does that math actually match up with the original geometric sequence for |R|>1
>>
>>9166698
Why does the geometric sequence R^n where |R|>1 have the closed form of -R^-1/(1-R^-1)? Why do those two things have any relation? Why does a divergent series have a closed form?

NASA employees over 17,000 people. Every year you should expect a percentage of them to die, and of that percentage some of them should be somewhat weird deaths

Hello everybody!, I search a book, if anyone have it, can you share it with me?, the book's Introduction to Quantum Mechanics by David J. Griffiths, I mean, I want E-reader version.

Thanks!

Say Lord Phenotype was 20 years younger. Also say M-Theory was verifiable and tested and proven to the the Unified Theory of Everything and he wins the Nobel Prize in Physics. Would that guarantee he could get any job at any company in the world? Assume he retires from Maths and Physics after winning the most prestigious awards in both as well as solving the most important Physics problem ever. Even though his research doesn't tie into anything, could he just demand a job at some Wall St bank, Google job, Nasa, Military, etc? Would they try to hire him just because of his sheer geniusness?

Can anyone help me to find a common mendelian trait in humans?
In my genetics class we are going to make genealogy for a mendelian trait and it has been a little bit hard to define one.

Yeah, the Solar system isn't stable, but it'll take loooooong time before it will cause any trouble for us.

Remember, discard the number nine, to know if the results of their sums and multiplications are correct.

>times it by five

So what about an "infinite set"? Well, to begin with you should say precisely what the term means.
Okay if you don't, at least someone should. Putting an adjective in front of a noun does not in itself make a mathematical concept.
Cantor declared that an "infinite set" is a set which is not finite. Surely that is unsatisfactory, as Cantor no doubt suspected himself. It's like declaring that an "all-seeing Leprechaun" is a Leprechaun which can see everything. Or an unstoppable mouse is a mouse which cannot be stopped. These grammatical constructions do not create concepts, except perhaps in literary or poetic sense. It is not clear that there are any sets that are not finite, just as it's not clear that there are any Leprechauns which can see everything, or that there are mice which cannot be stopped.
Certainly in science there is no reason to suppose that "infinite sets" exist. Are there and infinite number of quarks or electrons in the universe? If physicists had to hazard a guess, I am confident that the majority would say: No. But even if there were an infinite number of electrons it's unreasonable to suppose that you can get an infinite number of them all together as a single data object

Set S is infinite if there exist T proper subset of S such that S and T are equinumerous
