>That picture
Is literally the dumbest thing I've read in my life (okay except the flat earth threads). They either aren't there or are just to far away to find. Based on all available evidence, you should pick the later, they aren't there.

I mean seriously, how do people not go insane by deriving and proving such equations? I want to understand what makes people love doing this?

There's a lot of information in these symbols. I'll admit right now that I have nfc what this is actually saying. I know what the individual symbols mean but they're all crammed together without explanation so it's hard to get the whole picture.

In short:
On one hand when you say something like "the hessian is the jacobian of a gradient" you need to understand what the jacobian and gradient are. On the other hand, if you define the hessian without bringing up what these other terms are, using the definition of a limit or something even more elementary, you'll end up with a ridiculously unwieldy definition that reinvents the wheel at least three times.

>that the universe just "clicks" into place
It never just clicks, the moment when it clicks always comes after years of hard work. I remember watching Horizon interview Wiles about his proof, and he said that (after a decade of work) he a sudden moment of clarity and it all just fell into place.

make a real question with your chemicals..

biochemist here
let me try

>>8973935
Chemist means youve run reactions that arent from a kit

It wouldn't have been that extreme. It would happen in very tiny increments, with many levels of pseudo-consciousness in between what you consider conscious and not conscious. We are only used to such extremes because homo sapiens happen to have developed the highest level of consciousness, and also out-survived everything even remotely close. This leaves a large gap between humans and the next highest species.

>>8971841
>non-human animals aren't conscious
How/when/why consciousness evolved in animals is a better question
I think it is an emergent property of cephalization

most likely small change, starting with awareness of surroundings, then others, both seen in most modern mammals. monkeys have very basic society since they ae aware of others. then goes to awareness of self-seen in modern man

If it fell into the wrong hands, they could bring entire countries to their knees.

Time for the Redpill on antimatter.

#1 Antimatter Weapons
When an antimatter particle makes contact with normal matter they eliminate each other almost instantly.
This means that the other antimatter particles that haven't made contact with normal matter are now being pushed away or vaporized by the blast.
You'd need to come up with a way to make every antimatter particle in the warhead make contact simultaneously.
A "real" antimatter bomb would likely use a 1 atom thick wafer and be many little bombs for carpet bombing.
The main benefit is that, in theory, antimatter bombs would have much less mass than comparable ordnance.

#2 Antimatter fuel
Lasers, particle accelerators, and other tech used to make antimatter is not efficient at all.
It cost more energy to produce antimatter than what output you'd get from the antimatter.
The only reason to produce antimatter as power source on earth would be for low-mass, space based applications.
Assuming cost is not an issue.

Basically antimatter is extremely inefficient but it has a high energy density making it good for low mass applications assuming you have billions and many power plants.
>>8975436
that's wrong

>This means that the other antimatter particles that haven't made contact with normal matter are now being pushed away or vaporized by the blast.
Your anti-matter bomb doesn't need any regular matter in the explosive. All you need to do is release the anti-matter into the air, and it will annihilate with nitrogen and oxygen atoms in the air.

mutations happen all the time and have been observed, what's the problem? sometimes they are bad, sometimes good, sometimes you can't even notice

The benefit doesnt have to be enormous when the timescale is.

Most of those in the list were officers in the military, and they had to pass some kind of IQ test to become officers. Schacht was a mathematician or something. Anyway, history has proven them not so smart after all.

they were 'master race' for a reason

>Jüdische Physik

If they were so smart why did they mistake themselves for Gods chosen people?

your university should have methods of alternative testing (like taking it at a different time in a different space and getting more time), so try taking advantage of that.

ive heard of people being prescribed benzos for this as well, just a one time thing for whenever you have a test. but you want to keep the dose low as fuck for that because an actual benzo high would be a really bad choice for that sort of thing.

Sometimes, I dont prepare for exams realy hard to feel extremely excited to work in a harass conditions. It's such a pleasure to solve everything, then you done it without cheating.

Holy shit shut the fuck up! The boomerang is one of the few objects that can aerodynamically work only because the earth is flat, being the ultimate proof of what we already all know but (((they))) want to hide.

DELETE THIS THREAD RIGHT FUCKING NOW.

wow dude you're like a comedian! so fucking funny.

Because once we figure out peroskvite solar cells we can put solar cells on pretty much everything. Your house, your car, your shoes, your dog, etc.

We'll generate so much solar power it won't be funny. Coal, natural gas, nuclear, and wind power will succumb to the mighty sun!

Pv is only 30 percent efficient

kek, good thread. Is this a real doc in you or your friend's lab?

Phenomenology of the Spirit and competency in Non-philosophy are the bare minimum

Don't book usually sum up in the introductory chapter the thing you're supposed to know? If so then just get books from areas they mention and you should be golden.

We don't, we just accept it.

The picture says it all. Lopsided boobs with one missing nipple? We don't want to think about it.
