ask someone with a phd in math anything
>phd in math 300k starting is not a meme
give me a quick rundown on your thesis
For those of us who have a nagging feeling they like math but were too fucked up in HS to get it, can you do a brief escalating explanation of the diff levels of maths, from arithmetic through algebra, calc, geometry etc up to the highest level? That would give me/us a conceptual framework for what has always been the equivalent of a jumbled mess of Chinese. I'd like to know what they all are and how they relate and build off each other bc I was farting in class when I was supposed to be learning.
Thanks man.

>liberals think that global warming is an actual problem
I mean shit dude, why not just have a ton of refrigerators open. That'd solve Earths heat problem in like a day. Too bad their stupid cult wont let them hear any obvious and different opinions.
what really triggers me is the people who say "why do i care about rising sea levels lol"
because these people are often the ones who get worked up at refugees coming into the country and they really don't see the problem
Ikr! I mean it just snowed yesterday. People need to stop accepting the lies being fed to them by china.
>>8727870
but the people who don't care about rising sea levels also don't care about refugees
i.e. if the government wasn't forcing them to accept refugees into their country there wouldn't be any problem to begin with

yes, he certainly has explained magnetism in a way that you could comprehend. The only problem is you just have to watch a shit ton of his videos and he makes them each 20-40 minutes long and repeats himself a lot. Still awesome to see the shit he does with ferrocells and dangerous magnets.

NASA has announced the Cold Atom Laboratory (CAL), developed by Jet Propulsion Laboratory, is in the final stages of assembly at JPL, ahead of a ride to space this August on SpaceX CRS-12.

https://www.jpl.nasa.gov/news/news.php?feature=6765
My friends and I argued about the measurement of "colder" in the last sentence above, and my proposed solution is to measure coldness by an inverse Kelvin (K) unit, and call it Nivlek (N). Thus one billionth degree Kelvin (10^(-9) K) is equivalent to one billion Nivlek (10^9 N) which is indeed 100 million times greater (colder) than the 10N (0.1K) depths of space. What say you, /sci/ ? Genius or madness?
>>8727278
or they could just call it a nanoKelvin (nK), you daft faggot.
>>8727278
>Nivlek
I prefer degrees Tiehnerhaf, personally
Are you stupid? Taking the inverse of something doesn't need a new unit.
Also, measuring coldness is a dumb idea because temperature is a measure of energy, it's stupid to measure an absence of something. That's like measuring the darkness by the lack of photons.
Temperature already has a rigorous definition as the inverse of the derivative of internal energy with respect to entropy.
In total, you're a brainlet

Alright /sci/, so I've come to understand that in order to become good or great or even exceptional at something, one must practice the ever living shit out of it.
But the thing is, there are four things I want to become great at: Math, Art, Programming, and Writing.
So, how many hours a day should I dedicate to each of these subjects? In order from how much I care to the least I care:
>Math
>Programming
>Art
>Writing
Alright, so I should distribute the most time out of my day to Math, with the rest of the time falling into the rest of the subjects appropriately.
I wake up at 10:30 AM every day, and usually go to bed at about 12 AM.
So that leaves me about 14 hours or so in my day to do stuff.
So, 3 hours per subject? Or would it be more efficient to have days where I practice 6 hours of Math and 6 hours of Programming, and then days where I practice 6 hours of Art and 6 hours of Writing?
Am I trying to bite off more than I can chew here? I'm kind of a NEET so I have time. I'm not sure if I'll be able to do shit like this forever though because I plan on doing STEM.
>>8727217
Pick one thing and get really good at it.
Jack of all trades, master of none.
Then supplement the focused hard studying in one subject by giving yourself a couple hours a day to decompress with more enjoyable subjects with less pressure applied.
>>8727223
So, pick one subject to study 8-12 hours a day, every day. Then leave yourself free time to explore the other topics without as much rigor.
THAT would be most efficient for your learning of a subject, whichever you pick.

If you only use fluids and gas, then there is no friction right?

Anybody know how to solve this? I have been trying to solve this for the past few hours ;_;
Since it's symmetric, you can draw spokes coming out from the middle which divide the figure into 8 identical right triangles. You can just solve one triangle and then extrapolate the answer from there.
Let's consider the one triangle that is formed by drawing a line segment A from the middle point to the left, parallel to the bottom of the square, and the line segment B drawn from the middle point up and to the left so that it hits the top left corner of the square. There is a 45 degree angle between line A and B. We know line segment A has length 1, and B is length sqrt(2) from Pythagorean theorem.
The shaded region of this triangle can be calculated easily using trig because it bisects lines A and B, and we know the angle between them. Note that besides line A and B, the third boundary of this region must be a line because of the properties of the problem, so the shaded region is also a triangle.
>>8727001
I tried that, but isn't the region not a triangle? It is curved, so doesn't that not apply?
>>8726965
>besides line A and B, the third boundary of this region must be a line
whyy
shit doesn't look like a line to me, it all looks curved and there are no break points in the "sides" of the orange figure

Mistakes accumulate in our DNA because of increasing entropy. Evolution favored the ease of reproduction more than DNA repair tool kits. Actually DNA has very extensive repair kits. Think about it. The entire sequence is copied every single time your cells divide. During your life, there's about 70 trillion * 2000 divisions (you have 70 trillion cells and on average each cell divides every 2 weeks, 80 years has 2000 two-weeks)
