Are there actually any high-tier mathematicians /logiciens or even scientists or inventors that were also drunks or drug-addicts?
Seems like litreature is littered with them, but in hard sciences it seems like the worst you can find is einstein smoking his pipe.
Why is this?
>>7922092
Erdôs was famous for using amphetamines, a popular habit among a lot of the mathematicians I know
>>7922092
Because history is full of addict in general.
Because high-level math is a drug in and of itself
So /sci/, a uni I'm interested in going to is starting a "robotics" course this year. They arent saying what's on it because all the modules are still yet to be confirmed. If I apply, what's the likelihood that it'll be a legit mechatronics engineering course and what's the likelihood that it'll just be CompSci feat. Arduino?
>>7922008
Chance of being comp sci with arduino, 100%.
Be disappointed anon
>>7922008
The answer lies at the level.
Is this a course offered to seniors and graduate students or to anyone?
If it is to anyone you can be sure that it is just coding in C and touching some arduinos once every month. If this is exclusive to PhD students and seniors then it probably is a legit mechatronics engineering course.
>>7922034
Its a course offered from straight out of high school but the course lasts 4 years. Sounds like a dead end then? The alternate route is doing a BSc in physics then doing a postgrad masters in Robotics in another uni

Basically all the parts in chemistry where 2 atoms bond. I know the theory, but I only know how, not why they bond.
>>7921862
>People who didn't understand things
>why they bond.
I am no chemist but when my high school chem teacher would get asked why certain reactions happen in certain situation he would always give an answer similar to 'nature likes it that way' or 'nature prefers it'.
I think nobody knows. It's like asking why are the laws of physics like that.

Where were you when Petey Norvig's book proved that Alphago can't play 25x25 go and AI is impossible?
AI fanatics make me sick. cLEARLY they haven't read the works of NORVIG
>>7921703
And humans can? Only a few people in the world can play top level go on a 19*19 no reason to think it does not drop near to zero on a 25*25
>>7921706
You clearly don't know what you're talking about. Have you ever played GO? I bet you haven't. well, just to let you know, you don't need lot of time to become a GO top player, it's not like chess where you should spend literally all your life to become GM.
Six-seven months of study should be enough to become a GO top player, I heard that lee sedol started to play in its late twenties.
>>7921706
humans will always be better than AI at 25x25. clearly you don't understand deep learning since you havent read norvig
Could somebody please give me one scenario in which a proof by contradiction is the only proof possible or otherwise explain why it's good to learn proof by contradiction.
It's a very useful technique
Try to prove sqrt(2) is not rational without it
>>7921648
For all positive integers a,b we have:
[eqn] \left|\sqrt2 - \frac{a}{b} \right| = \frac{|2b^2-a^2|}{b^2 \left(\sqrt{2}+\frac{a}{b} \right) } \ge \frac{1}{b^2 \left( \sqrt2 + \frac{a}{b} \right) } \ge \frac{1}{3b^2} > 0 [/eqn]
I'm trying to build a short scifi story around these 2 events:
* aliens come to earth and abduct some humans
* humans send a rescue squad to go kill the fuckers and bring back the humans
1) What's a semi-plausible reason why aliens would come down to earth and abduct some humans to take back with them?
2) And how do humans with their primitive technology locate where the aliens came from and travel there?
>>7921603
>What's a semi-plausible reason why aliens would come down to earth and abduct some humans to take back with them?
plot twist, the aliens are future humans trying to save the race, but the humans of the now manage to destroy them and therefore their only hope for survival

1) because that's what they used to look like - to study their own [pre]history (been done before, Asgard aliens in Stargate)
1) to brainwash them and train them to act as proxy jihadis in their holy war against the decadent human infidels who insult the Creatrix by preparing delicious beverages from Her holy beans
1) to study the state of human technological and societal advancement... are these guys about to take their plundering ways into space and fuck everything up kinda thing, and how can we steer...

Hello, I have a few questions about what plants would grow best in a simulated Marian soil? Also what plants would produce the most bio mass with a minimal amount of fertilizer? This experiment is inspired from the Martian movie.

Look guys, I have been looking for a straight answer on this for a while. I don't like drinking or smoking weed, they fuck with my head too much, but I like tobacco. I have grown up with additive free cigarettes, and want to know if they are significantly safer than normal cigarettes. Every website I have looked at about this says the same thing, that it doesn't matter whether cigarettes have additives or not, they are all just as bad because inhaling all that smoke is bad. Well, inhaling smoke may be bad, but extreme stoners never get lung cancer, so how is smoking...

Logically speaking, safer than additive cigarettes, but they're not safe.
>What is the part of the cigarette giving everyone cancer, all the chemicals or the tobacco itself?
'Yes'.
Seriously though, consider just vaping. Who gives a fuck if you look like a fedora, it's much less risky.
>>7920949
Didnt read your post but I assume you are trying to rationalize smoking, which is fucking pathetic.
I used additive free cigarettes to transfer to vaping. Due to the lack of additive regulations you would be shocked how vile a Marlboro red is and they were a bit cheaper to quit when I did. When I was smoking I "felt" better moving to the nochems cigs but vaping is the way to go.
What is the difference between a shell and an energy level? Why do shells have the octet rule but more than 8 electrons should be able to fit into any energy level above 2? My uni does a "structure and properties, electrons and quantum first" style of learning chemistry and im halfway through the semester and doing well on tests but i still dont understand this shit
>>7920914
Cool, how's Chem 101?
>>7920926
This guy thinks he's cool
>>7920914
>difference between a shell and an energy level
apparently none. In intro to chemistry, energy level is defined as the quantum number 'n,' and a shell relates to valence. If you ask a physicist however, they'll tell you that each energy level 'n' can hold n^2 pairs of electrons, making them basically the same thing.
I think the difference is just the perspective you view them from, which is taught for simplicity
WHY ARE THE FUCKING BEES DYING
They figured this out awhile ago basically chemical runoff from farming stuff caused a disorder in the bees making them dessert the hive and die or go away or something.

How can the sum of all naturals numbers up to infinity be -1/12?
divergent series are not scalar values

try turning off your computer and turning it on again, then tell me if your problem is fixed
Is QM correct? Are particles really 'everywhere' until they interact with a classical system? How can a classical system confine a quantum object to a definite location if it itself is made up of mere quantum objects?
Personally it seems more reasonable to posit that things always have a definite position, but we're not always capable of figuring it out to arbitrary precision.
>>7920675
no rationalism is correct. Math do not describe the world, no matter what you fantasies are.
Mathematics is a choice of a framework to look at the world. Then the people embracing the scientific method choose to sort out what well formed formulas make sense according to them. since they know that it remains a choice to say that ''such well formed formulas describe the world (like the one of the free energy or the one of a black hole)'' but they cling to the notion of ''explanation'',...

Our conception of objective reality has this evaporated into a mathematics which describes, not the behavior of particles, but rather our knowledge of this behavior -Heisenberg
