Anybody know the name of a mathematician that owned very little physical items and just saw them as a burden? He only owned clothes and focused on his math work all the time.

Diagnosed schizo, by medical professional. not internet. so please do not post in my thread if you're an anti-psychiatry faggot, bat-shit insane christfag fuck you guys are crazier than me, or someone cliaming you can't know you're schizo and be schizo. stop watching movies you dumb little bitch faggots and stop spewing disinfo shit. fuck off. you always infect my threads. okay so I had to do a speech type thing for some class. 5 minute talking, 2 people. 15 minute total. 5 minutes of responding to class questions as well. I have not given a speech since the age of 13 sober. I took zeros until 18 when I got on Xanax and Oxy. I needed about 400-500mg of Oxycontin and 4-6mg of xanax for calmness during public speaking in community college. i developed schizo symptoms at age 16 or so. but visual hallucinations have not came until 6 months ago. I am 23. I did this speech sober, cause my dealer is a faggot about his opiates. his doesn't make much cash so it's "when he's around not wasting gas' and i can't afford a car. he couldn't bring me a packaged needle and the vial of liquid hydrophone i needed before the speech so I went sober. well I took 1 mg of xanax but that didn't dent the shit. first ever as an adult. jesus christ the stress. I have had a gun pointed at me and this was more horrifying and stressful and the fear. i started seeing things and this has only happened like 2-3 times before. never with this level of discomfort. I was fine for 45 seconds, and then it got hard to read. like i couldn't remember how. shadowy evil looking shit went over the cards. and evil shit on my hands too. shadowing evil things on the walls as well towards the end. I am pretty sure i sounded like a retarded fucking cunt and ruined this girls grade who was partnered with me. i stopped talking mid questions and stared at the cards and uggh. i did horribly. but i dont talk to anyone at school. ill just show up drugged and try to get a C. but since i saw shit, im feeling off

a new thing to worry your pretty little heads over /sci/... a hole in space, very close, aching to eat your fucking family... (sorry, I never post this stuff-- weird mood)

/sci/ will we start colonizing planets by the end of 2060. I would like to see humanity start to colonize other planets before I will die and I'm assuming after 2060 I will be dead.

Can you find the next number in this sequence? 4, 26, 324, 5116, 93740 Hint: it is a 7-digit number, followed by an 8-digit number.

I come to /sci/ to query as to whether any of you are on the same path as I. I do not want to simply learn a multitude of skills and/or subjects; I want to master the art of learning. This way, I will be able to learn and master any subject (such as hardware design, quantum mechanics, etc) within the minimum amount of time possible. This thread is dedicated to those who do not simply lack motivation, but to those who choose to remain still because they don't want to learn until they have mastered learning itself. If you guys know of any books, or simply want to share your own ideas, please post in this thread. Now, of course, one way to "master" learning is to apply yourself constantly and eventually learn "how to learn" by brute-forcing you way through. I see this as highly inefficient and this approach requires too much effort for someone like me. Thank you for reading.

I am doing an undergraduate degree in environmental science. All my subjectrs are chemistry, ecology type pure science subjects. I am interseted in geopolitics and I know little about how graduate research works. Can I proceed on to doing honours or a masters thesis in natural resource geo-politics, or another non-science type piece of work, say with an arts or economics department? Where could I go and do this? Is it normal? Will I have to get specific other training, or can I just jump right in. I know obviously that I will not be doing any 'empirical science' per se as my training has given me.

What does /sci/ think of nootropics? Do they actually increase memory, focus, creativity, etc.?

As the Aussie mining boom accelerates in crashing and burning as through this year, geologists will be the first to go, then regular mine workers including engineers, then down the line workers in metallurgy (chem eng)... How willl it all stagger out. Obviously exploration funds dry up and mass layoffs for geologists, oversaturated market since so many have joined but are too late; much less affected but still will be mine workers, who return to the cities. I'm guessing it will be an extra year or 2 of operation? Then finally down stream another 2 years staggered out?

How does /sci/ work through textbooks on their own? I figured I'd offer this for discussion because everyone has their own methods for teaching themselves material, and it would probably be helpful to talk about them. Maybe get some ideas for how to improve your pace/comprehension from others, and give some ideas of your own.

How come water can burn skin at temperatures below 100 degrees celsius? It's obvious that once the water in our cells starts boiling, things will go south, but why does a mere temperature difference have such an extereme impact on molecules in the same state of matter?

Emagine you're standing outside of our known universe, looking straight at it. Zoom into the universe, eventually you'll find galaxies. Zoom into a galaxy, eventually you'll find stars and planets. Zoom into the hand of a human, eventually you'll find atoms. Zoom into the atom, eventually you'll find a whole new universe. Is there an end to how far we can zoom? If you think about it, what's outside of our universe? Is the universe alive? Are stars and planets some kind of atom in a world beyond our universe? tell me what you think of this theory or if you've heard of it before.

So how much math do economists know, do they have to take PDEs, Complex Analysis and other stuff ?

Studying physical-chemistry (Atkins book). Author separates the wave equation in radial equation and angular equation. Says that if the angular part = something proportional to l(l+1) the solution comes immediately. I cannot seem to understand how he made this assumption.

group theory question- I have to show that in a multiplicative group, Ord(aba^{-1})=Ord(b) where a,b \in G . I've found that (aba^{-1})^{n} = ab^{n}a^{-1} . Now it seems we have to use the fact that G is a multiplicative group but I'm not sure what to do. Anyone have any ideas?

Something I have been wondering about for quite a while now. Does darkness exist? Darkness can't be broken down into smaller fragments, it can't be seen, touched, smelled, heard or tasted. So how do we know it exists? Scientifically, it can't exist because it can't be observed.

Let's say you were to design a spaceship that would be then built in space on a space station. The ship is supposed to go to other plantes fast. How would you go around delivering the parts to the spce station and all that? You have infinite funda.

OP is in need for a background image for his poster for a presentation about a dark matter project. Give me something to work with. >no text on it >it should underline important aspects about dark matter (don't just give me some pretty space pictures) >it should look professional
