1. Set an absolute time to get in bed. Do not negotiate with yourself. 2. Do *not* bring a phone/tablet/whatever into bed. If you can, don't have a TV or computer in your bedroom. 3. Stop working an hour before bed, and read a book or something else like that.
^ Good advice

@BernardMeurer Believe it or not, those hours at night spent installing Linux on a potato actually make you get less done overall because you don't perform as well the rest of the time.
At least, not if you have to get up to go to classes, etc.
@3075 TL;DR: College is expensive; Brazilian billionaire has a foundation that gives scholarships for Brazilian students going abroad; ultra super competitive; 6-phase selection process; I got to phase 5 which is a panel Monday at São Paulo (I live in Rio); Life changing opportunity, very nervous, very worried
All the things the DS says about sleep are true. And while you can force your way through a week on very little if you have to it takes it's toll. It will eat into your fitness, degrade you focus and memory until you get caught up, and tends to cause unhealthy weight gain.
It gets harder to force through it as you reach middle age and the consequence hit sooner and harder.
So establish the right habits while you are young.
I'm learning groups now. I have to do 30 more exercises to move onto the next section. Sometimes I wonder if it's even worth doing all the exercises qq
well some people say working through every exercise in a text is time not spent efficiently. I think that I learn something new in almost every exercise though so I'm going to keep doing them @mafia
until it becomes repetitive/i'm not learning anything useful/new then I'll keep doing them I guess
@MAFIA36790 Yes. You'd think smart people would make the decision to behave in a way that doesn't get them banned. Getting banned means you can't share what you know as much, which is less good. Unfortunately, not all smart people think this way, or they don't prioritize being able to participate as much as they prioritize standing on principles.
This is extra-unfortunate, because by participating you can help improve the rules of the community.
I am new to calculus and during my mathematics class my sir defined $\dfrac{dx}{dt}$ as $$dx/dt=\lim_{t\to t_1}\dfrac{f(t)-f(t_1)}{t-t_1}$$ and my sir made a clear statement that
$\dfrac{dx}{dt}$ is not a fraction it only behaves like a fraction!
(it means $\dfrac{dx}{dt}$ is just a notati...
@ramsay "Like, you shouldn't feel bad about thinking of these things as infinitesimals. That's the idea. But the reason people say not to think of dy/dx as a fraction is twofold. 1) Mathematically, that's not literally what it is. It's a limit etc etc. 2) Sometimes, if you are too uncareful with treating these terms as variables, you can come to a result that's just actually wrong. I don't have an example off the top of my head, but when I was teaching calculus, I saw this happen now and then. On the other hand, I don't have a problem with people reading this as "infinitesimal change of y o…
