>>7842190 calculus and differential equations preceded analysis. Analysis is a more rigorous "version" of calculus and other theories(complex, functional anaylsis) and is consider more fundamental while calculus is more about application and function.
Linear Algebra is quite a different subject but has applications within differential equations
>>7842190 >>7842193 Oh, and you usually take calc first, then diffy Qs or linear algebra after your 2nd semester of calc. If you want to take a real analysis course you need an introduction to proofs. There is also sometimes a more advance differential equations course aimed for mathematicians instead of engineers/scientist witch requires knowledge of proofs and linear algebra as well
>>7842183 I actually imagine they'd temporarily shut down her reproductive system else she'd be hindered in training when she's having to experience cramps, illness etc every 12 months. There are drugs like that that can last 3 yrs at a time.

I made a thread a while ago asking why if /sci/'s IQ is so high and you all attend top schools why has no-one here developed anything new and in addition to getting the usual "smart but lazy" bullshit but also many claimed that it's impossible for anyone without a PhD and huge research group to create anything new so why is it that many of the technological advancements of the 20th century were conceived of by amateurs? The airplane was invented by two bicycle mechanics, The stealth bomber was invented by the Horton brothers who were flying club members who never spent a day in university. The wankel engine, Felix Wankel never had a degree. Fast forward to the end of the 20th century the electronics age was virtually run by degree-less amateurs, Jobs and Gates etc. So why /sci/, why are untrained plebs pissing on all of your achievements? It is because you are not really smart, you're just good at passing exams. >tech is too advanced nowadays That's a "everything has already been invented" cop-out there is always new fields popping up. The 70s was pretty advanced what with trips to the Moon and fusion research going on yet Wozniak still managed to innovate. You can call yourself smart not when you have gotten into some college course or worse scored high in some online IQ test but when you have either published a research paper or hold a marketable patent.
>>7842002 It's good for normal people who are curious about basic scientific concepts and interesting anecdotes. It's not very suited to the flat earthers and moon landing deniers who infest this board, though.
On November 2nd, 2019, a letter arrived at the office of the president of the united states. It read, "On November 4th, 2019, the Washington monument will disappear. In two years, the entirety of the Hawaiian islands will vanish in a similar fashion." After a brief panic about a terror attack on the monument, security swept the area, found nothing, heightened surveillance, and sent a few more guards out to make sure no one was doing anything suspicious near it. On the 4th, the security teams observed the monument throughout the day, and closed it to tourists. At... Comment too long. Click here to view the full text.
So I wonder if there is scientific evidence that excessive masturbation and porn use is negative?
After hearing a lot of stories on nofap I got curious and tried it. Have been nofap/noporn for the past 3 weeks and honestly it feels amazing and will continue with it. But I also believe if it may possibly be placebo.
One of the few studies I've found show that on the 7th day of nofap testosterone in men is increased to 150% and then levels out after that:
There was another study that says it takes 3... Comment too long. Click here to view the full text.
Yes and no. Casios are generally inferior to the TI 8X series, and my scientific basis for that statement is that any time I play with a Casio, I just plain don't like the layout relative to the previously mentioned calculators.
I've played with 83s, 86s and 89s. They're fun for games and HS-tier stuff, and can even be used for arithmetic. Talking about the various functions of TI calculators is a total anachronism these days though, what with the much more powerful computers/calculators everyone... Comment too long.

If exoplanets discovered by scientists are what they were thousands of (light) years ago what if life developed on them thousands of years later in our present time? Theres no way to confirm the existence of alien life because you're always looking back thousands of years into the past with the telescopes!
Is the heat death of the universe theoretically survivable?
I'm arguing with my jackass brother, he says that as long as an inhabited planet produces enough heat and energy, that it can sustain itself through the nearly absolute-zero temperature of the rest of the universe.
>>7843142 No one thinks he's the smartest guy alive. He's just a mathematician who disagrees with the current dogma about the foundations of mathematics, and he has plenty of great mathematicians on his side.
