>You are standing in a field looking at the stars. Your arms are resting freely at your side, and you see that the distant stars are not moving. Now start spinning. The stars are whirling around you and your arms are pulled away from your body. Why should your arms be pulled away when the stars are whirling? Why should they be dangling freely when the stars don't move?
What did he mean by this?
Based Mach
He means exactly what he says tho?
>>8566244
Maybe I'm just retarded but I fail to see how the stars are relevant.
>Why should your arms be pulled away when the stars are whirling?
It is the spinning that creates the centrifugal force that "pulls" one's arms away, and the "whirling" appearance of the stars is just a byproduct of the rotating frame of reference. I just don't see why the relationship between the stars and the person spinning needs to be questioned?
Unless this is meant to be a thought experiment that pokes holes in the concept of causality, like Hume and other causality skeptics, but if that was the case I still don't understand the reasoning.
Thoughts?
Pure what? Pure logic?
All aspects of science carry the same significance and truth.
Mathematics have gone to far and is now riddled with thing that do not connect to the real world

They think that's good for some reason.
What is the most thermally efficient engine ever produced?
The Carnot engine. Though it doesn't work very well in practice because of the isotherms.
what kind of engine are we talking about?
The fact is that the sky is an artificial projection. We have gone to space. The images are not fake. Our governments are not aware of the Ringworld. However, it is the true structure of our world.
If we dig deep enough into the ground, we'll encounter the artificial vacuum of space, not a molten core, not China.
A species of ape was deposited here millions of years ago; over time, offshoots developed intelligence, agriculture, metallurgy, militaries, economies. This was expected by the aliens who put us here, who are still in contact with various groups on the ground, having gone into hiding on artificial constructs across the galaxy, like our Ringworld but in many cases larger (i.e. Dyson spheres, O'Neill cylinders, etc. to survive a holocaust being perpetrated by another faction of beings from beyond our habitat (we ourselves, being aliens, are also simply a faction of beings).

The scientific 'community' will never admit it. We have to build a spaceship ourselves and go up to space, expose the alien plot.

Any physicists here that can answer this question?
Give us some exact numbers faggot
It's never the same temperature as the water from the faucet because it's an exponential response. It'll infinitely approach the hot water temperature, but it'll never actually get there unless you add a bit of hotter water.

What do you do to get as comfy as possible when you're studying, /sci/?

I put on socks and sweatpants and study at the kitchen table with the divider shut between the living room and the kitchen.

Put down the metronome on a table. Sweatpants and a white shirt. Book and pen. Start the metronome and begin studying

Which book is more likely to get me a job /sci/?
Neither. Those are trivial books for dummies.

>Math challenges threads
Gave me interesting things to think about and help me realize my knowledge boundaries are farther than I thought they were, by solving problems people had no idea how to solve.
Also, not related to any thread, now I have a nice hobby which I can engage in whenever I am bored of real life and which does not take too much time nor is destructive: advanced shitposting. Like right now, I'm posting this from my work. Great.

This might be basic, but I'm still having a hard time understanding it.
Say 100 pieces of pie has to be distibuted to 100 different plates and the way they are distributed are random. (n=100, r=100)
Then what is the chance of all the pie pieces to be distributed evenly? I know that there are 100^100 (n^r) different ways of them to be distributed total, but don't really know how to find a formula for them not to "collide"
[eqn] \prod_{k=1}^{100} \frac{101-k}{100} [/eqn]
Try your problems with 3 pieces of cake.
It's a piece of cake.
>>8571278
Alright. Let's say 3 pieces of cake has to be distributed on 10 plates then. There are 10^3 (1000) different ways that the pieces can be distributed.
I still don't know how to calculate the probability of then getting their own plate. I figured I have to divide with 1000, the total amount of combinations, but how?
Is Mochizuki just meming us?
Not consciously.
What the actual fuck is this dharma product?
I'm only familiar with Mochizuki from the memes. What is he supposedly trying to accomplish with ITT?
>>8571165
I don't know shit about ITT, but why does he have to use these ridiculous symbols and fonts? Why can't he just abuse notation like a regular mathematician?
When are you guys going to adress the issue that geoengineering is the sole reason for climate change and not carbon emission?
The only reason that the elite has been pushing climate change being caused by carbon is because of carbon taxes which you know is a trillion dollar market.
There's 400+ weather modification patents that you can easily just google, private corporations investing billions of dollars into technology that they have no interest in?...uhhhh... does that make sense? Keep in mind, weather affects all global financial markets, stocks, commodities, currencies, you name it.
Also, all NATO countries have signed weather modification treaties.
How could they possibly alter the weather? Quite easily desu haha, nano sized conductive metal particles sprayed in the upper atmosphere, then electroMAGNETIC frequencies to coerce it around, can pick up moisture, or cause droughts, both of which crank prices for things like food and water, who profits when that happens??

This is not a conspiracy. This is fact. 400+ patents just for fun? Uhm... Ever been outside of your basement and looked up into the sky? Chemtrails all over the place bud.
Gee /sci/, why is Theoretical Computer Science a field of study at the MIT Math Department?: http://gradadmissions.mit.edu/programs/math
I thought they were all code monkeys, and shit. Really makes you think.
so the maths department get more free computers, brainlet
>>8571075
Because Computer Science is a subset of math.
If your university has CS classes taught by the math department then take them, those are good classes and they are mathematics.
Just look at those names. Algebra, Topology, Analysis, etc. That is a math degree!
But if you take CS classes taught by the Codemonkey Studies department then you will get 0/10 garbage.
>>8571075
Computability and complexity theory are really interesting and worthwhile branches of logic (in my opinion)
Analysis of algorithms slightly less so
There is other who think that this guy may be real ?

Need to solve for x. Been trying for 2 day. Any ideas?
The first two are merely definitions of a function. There is no nice closed form for inverting the Gamma function, but there are papers out there on how to compute/approximate the inverse.
The expression on the left hand side of the last line is equal to pi·csc(pi·x), where csc is the cosecant. If I'm not confused, it only takes values between 1/2 and 1, monotonically growing, and for all other values they are mere periodic repetitions of those. And At 1/2 it's pi, which is larger than \sqrt(3·\sqrt(3))/2, so there's no solution.

[math]x_{\pm}^{(n)} = 0.318\left( \pm 1.672 i + \pi \left( 2n + \frac{1}{2} \right) \right)[/math]
There's probably a really smart way to do this, good luck.
>>8570936
I thought at 1/2 it's sqrt(pi)/2 no?
