Why is sexual desire so ingrained into us? Why does it keep coming back even after copulation? Why do we start developing carnal desires at such a young age? Why do sexually appealing traits commonly no longer appeal to us post-orgasm? Why do a lot of us value purity? Why do a lot of us seek existential knowledge and value it more than sex? Is purity even needed anymore? Is promiscuity the way to go now? I can't fathom this inherent burden.

We haven't evolve that much, OP

The tl;dr of your shit is that we are supposed to impregnate all the girls you see every day, but also purity became with religion since we naturally don't want a girl that has taken the D before
But IMO, purity shouldn't matter to you if you're not a virgin, just get a non-virgin girl and be happy with her
>>
>>8495094
I feel you OP.
I have two primitive desires: fap, and advance science. I could do much more on the latter if my sexual appetite wasn't so damn high.

Hello. Looking for students at NYU, Columbia, Johns Hopkins, OSU, GA Tech, Harvard, Princeton, York, and UC Boulder - preferably grad students in math or physics. I am doing PhD applications at these schools and will be visiting soon - if you'd like to meet up for coffee, talk about research, explore campus, etc then we can exchange emails and such.

The sun transmits energy to us from thousands kilometers away. Energy enough to feed our plants needs, which feed our animals, which feeds us. Why cant we use electromagnetic waves to transmit wireless energy, like the sun does? Maybe using a Teslas Coil?

Honestly, what is the benefit of using an operating system that is specific to your application?

And I mean it, it is a genuine question. Windows can run all the scientific software too so what specific benefits do you get from getting "scientist" operating systems?

My topography book uses some dumbly obfuscated matrix operations instead of saying something like "add each angle to the previous and divide the sum by C".

Why do you have to do this you dumb cunts?
I can tell you're trying too hard to make this look important. Just stop and make everyone's life easier.

One of the lab managers on my floor has toxo (he's from India). He's a very fun guy and seems very well balanced, has a wife and daughter and is well-liked. Toxo may indeed be a meme "disease."

this is the weirdest bait I have ever seen

go to a sheep farm and tell a farmer toxo doesn't exist, watch him laugh at you

>>8496477
I think he might be talking about toxo in humans. While the microbe definitely can infect human, whether it constitutes a legit disease with serious effects is controversial.

I'm trying to give a precise proof that the limit is false ,did I succeed in doing so?
41 posts and 4 images submitted.
>>
seems like you're on the right track but the wording/logic is very awkward

what is N? why is 1+1/n^2 <= 1+1/(1/sqrt(epsilon-1))?
>>
>>8495906
Your proof falls apart for all epsilon greater than 1. For example choose epsilon = 10 then the left hand side equals 4 which is clearly not greater than 10.

To prove a limit is false its best to show that there exists an epsilon greater than zero such that for all natural numbers N, |asub(n)-L|>epsilon if n>N. Try that instead of proving it for all epsilon which most of the time won't work.

Basically you can sort elementary particles into two groups: Fermions (like electrons), which have half-integer spin numbers, and Bosons (like Photons), which have full integer spin numbers.

The Pauli exclusion principle says that no two Fermions can occupy the same state, this is why in Atoms each energy state is only populated by two Fermions (spin up and spin down).

Bosons however can occupy as many states at the same time as you have particles. Now, what happens when you put a lot of Bosons into some system (like some harmonic potential, or just a box) coupled to a heat bath, you will find that Bosons will occupy the possible states according to some statistic (or rule or formula). And what we find for Bosons is that even though the system provides heat to populate higher states, most Bosons will only sit on the lowest energy state. This is what's known as the Bose-Einstein condensate.

Btw, did you know Bose was an Indian?
