What is the evolutionary advantage of death?
>>7835919
It gives us hope that some day we will have peace from all this suffering.

I can't help but notice that while we say the second law of thermodynamics in inviolable, most imagined violations of it are also violations of the law of conservation of energy; for example, if a system spontaneously reorganises itself, there's a gain in potential energy but no loss of energy, therefore allowing free energy, explaining why a system cannot spontaneously organise itself.
However, if an electron where to somehow build up energy from weak photons then release it all as a strong photon, no energy would be gained or lost, but entropy would decrease;...

Entropy is not solid at all its just like quantum mechanics as its a great model as far as the math goes and accurately predicts the real world but it makes no sense from a cause and effect standpoint
>>7835518
But then if it's so vague, why don't we have a lot of technologies supposedly ruled out by entropy?
For example, simultaneously lighting and cooling something by having electrons go up energy levels from infrared absorbtion then drop to their lowest energy level again emitting a visible photon in the process.
>>7835522
Laser cooling exists
Entropy is empirical. Theoretically there's no reason why something couldn't reorganize itself or time move in opposite direction. It just doesn't happen

Why does fraud in academia persist?
>>7835392
Subpar researchers need to eat too.
publish or perish
>>7835392
Academic career these days is sheer murder. There are far more newly minted researchers with a PhD than there are rsalaried research positions and even fewer open positions for tenure.
Add to this that universities knowingly loos away when peole enter publishing cartels to pump up the statistics and you are approaching the rot that is academic state of today.
So you get Retraction Watch and people out for revenge like Francis Claire, a pseudonym for someone hunting down and exposing frauds.

What does /sci/ think of the STEAM movement?
>Science
>Technology
>Engineering
>Arts
>Mathematics
>>7835165
Arts is more or just as important as sience and mathematics.
>>7835171
But it shouldn't be in the same category as STEM
>>7835165
We discussed this years ago. That OP actually posted sources, unlike your lazy ass.
Anyways, the website from the people pushing these said that the goal was to make more jobs for liberal arts people inside of big tech and science companies.
Their excuse was that 'pure creativity' was needed to keep a business running but that is bullshit..That assumes that people that do engineering, or high level math, or whatever, cannot be creative and have ideas on their own and need a babysitter liberal arts major to help them out. That is not the case.
Most start ups are made by STEM graduates and most CEOs are STEM graduates. We don't need 'idea guys'.
And this leads to the main point. All that I have said is known. We know this. They know this. So then why use that as their main catching point? Obvious. Liberal arts degrees are becoming literally worthless, with people reporting not getting jobs for 2 years after graduation at all. They just want to push this agenda to trick companies into hiring their liberal arts graduates because if not, they will all be stuck making minimum wage at Mc Donalds.
And that is all there is no it. It will never catch up because it doesn't bring anything interesting to the table. It just wants liberal arts majors to feed off the prestige that 'STEM' has.

Hey /sci/
Of late a few of my close friends have fallen into the crowd that inhales n2o (nos). I have done a fair bit of reading up on this and I really can't get a conclusive answer as to whether its bad for you or not. I would love to try it if its not going to cause long term side effects. Can chem majors or chemists or doctors for that instance give me a decent answer?
tl;dr: Is inhaling NOS bad for you?
Thanks in advanced :)
From what I read, it doesn't seem to be bad for you, but I didn't go too deep.
I can tell you that that shits not worth it. I knew a guy who was doing it and I tried it one night. You get high for like 5 seconds off one and that's it. The high was kinda funny, but it's just stupid. Who the fuck wants to be high for 5 seconds and have to do another?
Okay, see thats my issue, there is nothing very conclusive.
As for the high, if I tried it, it would generally be a one off thing.

There's a real chance you can freeze your lungs and die, depending on delivery method of course. I know someone who had this happen to his girlfriend. There was no saving her.
Anyone else have a high interest in math and science but low intelligence?
I have 99 IQ and taught myself up to differential topology and QM.
I have really shitty initial comprehension skills. As in i will need to have something explained multiple times or have to study something in proper context to understand it. However when i do understand it, i understand better than most other people. Not sure if this is a condition.

I'm this way too.Tbh I reckon nobody is good at first read comprehension.
Chesscademy is a great place to start learning.

5 flips so possible combinations are 2^5
Only 1 out come t t t h h
So probability is 1/32

It could be HTHTHTHTHTHTHTHH

The preceding flips are irrelevant.

And breathing through your mouth is essential for any kind of physical effort.
Running to hunt your prey or escaping from a predator is millions times more beneficial than not choking on food even if you're a retard who can't eat properly.

Is this book a good starting point for someone studying proofs for the first time?
Can you guys recommend some other intro to proofs books?
>>7833056
This is my favorite intro to proof book.
It's very short, very well-written, and covers some useful (and interesting, in my opinion) things as well rather than the contrived examples many how-to-prove-it books are filled with.
It's also cheap, which is nice.
Keep in mind that there's very little to actually _learn_ about doing proofs. Only a few pages.
The important part is to do a fuckton of them to get experience with writing and reading proof.
How can I calculate the volume traced by a circle in R^3 that rotates x radians while translating a distance d along a line? (center of circle stays on the line)
At the start the circle is oriented along the xy plane and it's translated along a line in the xy plane while rotating "forwards". For example if r=1, x=2pi and d=0 it's obviously a unit sphere.
How to plot the resulting shape?
