What sort of math classes do you guys use LaTeX for? I have always heard on here about people using LaTeX for math homework.
I'm in a differential equations class this semester where the homework is just assigned problems from the book.
I'm kinda curious and I have always wanted to give it a try, but do people do that for math classes like differential equations or is it better suited for things like proof classes? Would it be more trouble than it's worth? Would I look like a tryhard?
you'd look like a tryhard. I started using latex for discrete mathematics/intro to proof class, then I kept using it for abstract algebra, real analysis, PDEs, etc.
I use LaTeX in my Differential Geometry, Real Analysis, and Modern Algebra classes. I didn't start before this year because I was
>le smart but too lazy to learn how to do it
It's good for anything with math notation
>An recent analysis showed that 15-year old students in countries that are high-performing in Math memorize less compared to their contemporaries in countries which are low-performing countries.
>It is common belief [among brainlets] that mastery of math skills require memorization. However, it is i̶n̶t̶e̶r̶e̶s̶t̶i̶n̶g̶ [common sense] to find out that those countries who have the highest math performers do not rely on memorization at all.
>"For example, fewer students in East Asian countries reported that they use memorization as a learning strategy than did 15-year-olds in some of the English-speaking countries to whom they are often compared," an excerpt in the 93-page report said.
>Some of the highest performing countries in math include Japan and Macao, China. The report said that mathematics instruction in East Asia has greatly changed throughout the years with students relying less in memorization or rote. On the other hand, the percentage of American students who said they do not use memorization have an OECD score that is just above average.
>The survey also revealed that when students are most happy, they use memorization less as well. With happy, it is defined as the student having a positive attitude, confident about their math abilities, experience no or less anxiety in math, and highly motivated in solving mathematical problems. Aside from that, the study also revealed that boys memorize less than girls and these results are similar across all participating countries.

Said nobody ever, the actual stereotype is that they cheat.
>>8415315
national averages in asian countries are based on a few top schools, in western its an actual average, so the top schools average grade is barely better than the average. Whites>everyone else. And jews are totally not trying to make a sub-intelligent genology so they can be smartest.

My lecturer was project manager for a sensor that was embedded in the lander. He once said me "...let's hope the new Alenia retrorockets work properly"; he didn't seem very confident.
There's a chance Schiaparelli will smash into Mars.

Feel free to post about mathematics in general, just keep the shitposting about 300k starting, CS, and stuff out of this thread. Let's actually talk about something meaningful this time.
>what are you currently reading?
>any problems?
>any suggestions for cool exercises?
Personally right now I am doing some reading in Kähler manifolds, in particular from the viewpoint of symplectic geometry.
I was wondering if anyone has any good books on differential equations as that has been a very abandoned subject for me since my undergraduate years. Maybe there is a good book in Springer's library? Thanks!
I wake up in the morning and the first thing I remember is that I have my goddamn doctorate in mathematics, this results in an immediate rush of endorphins and testosterone which will last for the rest of the day. I then get to work writing down the proofs to the theorems that I solved in my head last night. After that I fuck my 10/10 wife while thinking about my research. I then leave without eating breakfast since I no longer require sustenance. Next follows morning lectures gracing plebs with some invaluable insight into my mind and its firm grasp on the most important field of study in human history. The rest of the I spend developing various mathematical structures on blackboards, the results of which will applied to curing all cancers and building thermodynamically efficient cold fusion reactors. As the day winds down I ponder my surreal existence, I have to dig up my degree to remind myself of the reality that I do in fact have a PhD in mathematics. Finally I fall asleep holding my doctorate and 300k salary slip in my arms.
And then I do it all again.

I'm a mathematics undergraduate and I'm doing a bonus-project on stochastic processes. Right now I have gone over the Brownian motion (properties, Lévy construction, filtrations), and I at least want to go over the stochastic integral after this. Any recommendations for other things I can include? Or recommendations for literature?
>>8416227
You could take a look at ergodic theory afterwards. It might be a bit off to the side but you never know.
A reference suggestion for that if you wanted to look at it:
"Ergodic Theory, with a view towards Number Theory" - Einsiedler, Manfred, Ward, Thomas

How do you approach this type of probability problem?
What's the probability of a bag containing X white balls given that the bag contains T white and black balls (each with the same probability) and you sampled (with replacement) Z balls out of which Y were white?
I have a value of right ascension and declination and need to find "pixel size on the sky" in arcsec/pixel from these (Context is aperture photometry) but I can't find any information about how to do this. Is this just (RA/dec)/1 with both values in arcsec?

I am dumb so I need help with this
Say I have an electric motor that can put out 1492 watts of power (about 2 hp). If I put it on a small bicycle, how can I use this info to determine force, acceleration, velocity, etc..? Say the bike with a person on it weighs 150lbs ( about 68kg of mass)
I know Power = Force x Velocity but then what?
I've tried picking an arbitrary velocity to find Force, but I am unsure what this result represents.
Say friction is negligible and velocity is at 9 m/s. So 1492 Watts = Force (N) * 9 m/s
which leads to Force = 165.7 Newtons.
Is it appropriate to move onto F=ma with this result? That would lead to acceleration = 2.44 m/s^2 but I am unsure of these calculations.
Thanks

Small fucking world. I was in that lecture.
>>8389942
Hw are you defining "chemical graph" in this case, so that BeH2 and H2O are different? N-1 loops on a node for atomic number N? What about isotopes, stereoisomers, etc?
I saw a book calling itself chemical graph theory once but I'm not aware of any seminal achievements
Group theory, though, is open season
Are there any actual people here attending ivy leagues? Or are the majority of people on here college drop outs with an interest in science? I wanna know who I am associating with here.
The majority of the people here, at least in my understanding, are those who attend an average or higher standing science oriented university

Hey guys, is CRISPR going to help humanity in the near future?
Not like end aging or cure death, but more like take care of smaller problems?
Minor disorders, Male pattern baldness, blindness, intelligence, better immunity or anything along those lines?
To be hones my biggest fears are;
1) being old and bald
2)not being able to stay in shape when im old
seriously, i just want to know if we can at least cure some minor shit. I dont want to age like my grandfather and have alzheimer's at the age of 60, thats just fucking sad.
(i know cure isn't exactly the proper term but it works, i also know minor doesn't = easy to fix but im just curious)
what do you guys think? can it do ANYTHING to change our lives in the near future? (10-40 years)
>5-7 years
cure minor shit like baldness
>10-15 years
cure chronic diseases
>15-20 years
designer babys, give your baby extra ordinary intelligence, strength and other shit
>20-30 years
immune to every disease
>30-40 years
slow down/stop aging
>>8419942
>30-40
>become immortal
you made me feel nice but i have to be skeptical, is it realistic that we can cure things as minor as baldness?
Would people even do research for that shit?
all i see is people talking about designer babies and super powers, but what about every day shit? can this shit cure my allergies? will people even care to do research for minor problems? or will they brush them off as being not important enough.
i think CRISPR wont cure shit, not anytime soon, because folks would concentrate on fixing disorders and big issues, not small ones. (and that would probably take longer)
that, and the "ETHICAL" aspects of this thing (like its ok to be high and mighty about having ~pure~ kids, even if they can literally be born with NO FUCKING BRAIN)
I so fucking hope im wrong.
>>8419955
You have to start small and convince people that CRISPR isn't some new meme technology that will be forgotten in a week, but a life changing technology.
Curing baldness would be a good start.

How do you feel about the Chinese being the first to genetically modify embryos with CRISPR?
Can you imagine a society that's so collectivist and pragmatic that they don't value human life at all like the Chinese, taking over the planet with genetic super babies? Are we entering a dystopian future?

How can we make math more trendy?
I'm a (pure) mathematician working on my phd. When I'm in bar with my CS buddy, women always find it cool that he makes websites and mobile apps for a living. Meanwhile no-one is ever interested in what I do, and I couldn't even explain it to someone who hasn't the sufficient math prerequisites (i.e 99% of population).
>>8419992
People usually tell me that it's cool and that they loved math and that it's for smart people. But yeah not much of a conversational topic regardless.
>>8419992
Say 1 thing that a pure mathematician do that is directly relatable to an average person. None.

Why is Titanium so fucking great?
>doesn't rust
>twice as hard as steel
>60% lighter

Anyone know if jet fuel can melt titanium beams?
>>8419921
Melting point is at 1668 °C.
So no, it can't.
>>8419919
>doesn't rust
>Like aluminium and magnesium, titanium metal and its alloys oxidize immediately upon exposure to air.
Sure, it forms a protective oxide layer that prevents penetrative rust, but if you are working with nanoparticles (and if you aren't, then you are losing the game) that doesn't help you at all.
They can't even get a rocket into orbit without it exploding, so why do people think that they'll be able to build THIS in 5 years?
Serious question.

What >>8426078 said
Every space program and company has had its explosions. And accidents are bound to happen when you push for new things
That's the reason people love SpaceX though, it's because they're pushing for new innovative tech and what they've developed already is groundbreaking.
Personally though, I am skeptical that they'll develop the mars colonial transporter in the next 5 years, but I would love to be proven wrong
But people love SpaceX because they're pushing for new innovative tech. SpaceX fanboys don't just fap to SpaceX, they fap to Blue Origin too usually
