Do you meditate /sci? Seems it has a lot of health benefits.
>>7781910
Waste of time. Doesn't work.
>>7781921
Not with that attitude it won't! Modern life is so full of instantaneous gratification it's important to be able to quiet the mind.
>>7781921
you talking shit about meditation faggot?
Is this the best book for learning multivariable calculus?
It was pretty good for single variable. I have the exact same book and will be comparing it with Sallas's or so this semester.
>>7781889
pretty solid. This book got me through my E&M course with an A.

is physics 90% math? or 100% math? or 50% math?
and what is the remaining percentage (unless you say it's 100% math) ?
i could only come up with quantum physics (possibly) which i guess is statistics and probability... but that's also math, isn't it?
to me it seems like physics is 100% math + real world situations. essentially applied mathematics.
quick help me so i can win this debate vs my gf.
>>7781779
Physics is 0% math.
Applying math is not doing math. Physics is 100% physics and nothing more.
>>7781782
... you are an idiot. that's okay though, i'll just wait for the next anon to pop by.

How hard is a Physics major? What should I start off with?
>>7781732
Fairly easy
>>7781759
kek
>>7781732
Easier than math but harder than biology.
ITT: You sum up your major in one sentence.
I'll start:
>Chemistry
>bonds form, bonds break.
machine learning
we need more computers
mathematics
we assume things and find other things out
>algebraic geometry
What if rings were geometric spaces?
Also acceptable:
>lol functors
is it true that every chemical reaction can be reduced to fire
>>7781583
Burning is oxidation, not reduction.
just as true as energy can be turned into anything
>>7781585
Reversed fire

Why did retarded mathematicians invent something as stupid as limits? This is the most amibguous shit I have ever been forced to learn. Even when trying to PROVE that a limit for a certain series exists, the proof just suddenly stops and q.e.d. Then you just whatever the fuck you want for your inputs and you're done. Circulatory logic at its finest. If only maths were the domain of engineering, then everything would have nice and clean order. Thanks for nothing, math-FAGS!
>>7781558
it's all tautologies anyway senpai
>>7781558
>itt anon has a hard time when meeting rigorous mathematics for the first time.
It'll come to you eventually, brah. Remember you get the freedom to conjecture some limit and some N.
Just identify the co-domain and then find the supremum or infimum of that set, it it necessarily well-defined. Thats it, shitstick faggot.
As I understand it (please do correct me if I'm wrong) at each moment of time the universe's ground state of energy fluctuates in multiple different ways which is the fundamental basis for nature as we know it.
However are these fluctuations deterministic? Why do certain actions with that ground state happen when they do? Is that something we're still trying to understand or am I just completely misrepresenting the issue?
It's all a long deterministic chain reaction that started (presumably) with the big bang. Everything after that is a result of action-reaction transfer of energy, which is based on completely physical, deterministic laws dictated by mathematical rules. That's all there is.
>>7781450
I assume you're talking about vacuum fluctuation.
This isn't actually a time-dependant fluctuation - the ground state does not change over time.
Vacuum fluctuation means that if you were to measure the magnetic field, say, of the vacuum, you'd find that the result is not zero, but oscillates around zero. This is essentially the same as Heisenberg uncertainty, but in field theory,
>>7781459
No, no, I'm talking about within a moment in time and not time temporally. If the fundamental elements of nature moved how did it move and why in that way in that moment?
I don't believe this is about the Big Bang.
Hey guys
I'm asking this here since I guess it's more to do with physics
Is it easier to knockout someone with a blow to the chin if his lower face is shaped like pic A than pic B? I'm assuming the head will yank easier and cause the brain to slam inside the skull
Also would a bigger skull provide more punch resistance or just an easier target?
Thanks
there are much more important variables at work here
this is the equivalent of asking
"hey /sci/ will I be able to make more money gambling wearing red socks or blue"
No, the structure has very little to do with it. It has more to do with how dense you can make your jaw when you receive the impact. Which is why mouthguards are a really good thing. But in the end it doesn't matter what you do, if you're getting hit by a force strong enough to knock you out you're going down no matter what.
>>7781449
>is shaped like pic A than pic B?
Wheres the damn A and B on the picture ?
How am i supposed to know which one is which
I've applied for a computer science degree and got offers but I don't really know what I should be looking for within the course structure that makes it a good course. Could someone help me out?

I choose to believe this is a joke

Well...it's copy-pasta, but the original poster was dead serious.
Is it even possible to learn maths by yourself? Learn how to do exercises and tests with faculty-tier difficulty, all by myself?
How would I go about that?
>>7781257 (OP)
Just open a textbook and read what's inside. That exactly what lectures are, reading from a textbook out loud. Sometimes lecturers add in their own stuff to make it more "understandable" but that really isn't necessary.
However, I do advise you to bring your brain when learning math, especially by yourself.

With open coursework on YouTube anything is possible senpai
>sample size 50 is enough for statistics
When will this meme die?
That source. Is that suppose to mean something?
>>7781183
>muh large sample maymay
With just 50 randomly chosen people from the population we get a pretty good fit. Pic related, the distributions of height of 25,000 UC Davis students.

Hello,
It appears that you are in Trig Identity Hell. Stay there for a bit. There is much to learn.
Cordially,

What did I do wrong.
I've had a another try and got to ...
4sinxcosx +1 +2sin^2x=0
>>7781168
Remember Sin(2X) = 2sin(X)cos(X)
I've been trying to think of a new science experiment. I want it to be spectacular. I don't know if it will work though. Can you do some checking of my work?
The plan is to get a string magnet and accelerate it with the help of a spring to a few hundred meters per second, then have it pass through a magnesium ring.
The magnet needs to impart enough energy into.the magnesium ring that it heats up to.The.point of ignition.
Can this work? Can the spring get the magnet going fast enough to induce enough heat in the ring to get it hot enough to.combust?
So what are you trying to do? The point of an experiment is to test a hypothesis.
>>7781133
My hypothesis is that the ring will explode with material I can easily and cheaply procure.
Why do you think the magnesium will ignite from a supersonic magnet passing through it?
Fucking shit /sci/. Fucking fuck fuck shit, /sci/.

Stopped reading right there. There is absolutely nothing of value a europoor econ major could possibly say. Saged.
