Between chemistry, biology, and physics, which of those is the closest related to mathematics?
Physics
>>8586202
Geology
Physics. But there are plenty of sub-disciplines in chemistry and biology that are math intensive.
Does anyone use this or a tablet to take notes/do homework? Do you find it superior to pen/pencil? Debating if I should use this or go back to paper.
I've found that tablets are much better for consuming information while laptops are much better for producing it.
I also don't like thumbprints all over my screen.
Not superior but very close to the feeling of pen/paper.
It is superior, however, due to its organizational power and ability to have all your notes on one device.
My daily carry has been reduced from a textbook or two and 3 notepads to just a textbook and a surface.
I recommend it fully, but you should try it out at a store first to see if you like how it feel to write.
Also as a laptop it works quite well, the only downside is that it won't support itself without your legs, so you need to have it closer to your body than a normal laptop.

that's about the same isnt it

Do any of you /sci/gays actually unironically find your studies "fun"?
You often hear from autists that they find math "fun" or they find physics "fun" or whatever, but I imagine that they either have an extremely skewed view of what "fun" is, haven't made it very far in their degree program yet, or are just pretentious cuntbags who think they're super cool for studying math. So, which is it?
>>8586054
Sounds like you hate your field of study. That's a mistake other people haven't made.
>>8586054
I study my field not because it's "fun" but because it requires less effort than the others.
i like some parts less and some parts a lot
im sorry you hate your choice of direction in life.

Numberphile said that the sum of all natural numbers, which allegedly equals -1/12, is used in many various areas of phyiscs. Can someone explain where and how?
>>8586024
There are THREE (3) threads about it
>>8586024
Why don't you pick up a copy of Polchinski and find out?
>>8586024
I only know that it is used in String theory. What are the other areas? I wanna know and see things actually works out when this comes into play.
I think that this whole manipulation of different series is a nice way to avoid dealing with infinity.

About what
>>8585876
Darwinism becoming an almost cult-like belief.
>Prof. Nagel’s thesis is provocative, no doubt. In just 128 pages, Mind & Cosmos argues the modern scientific story of the origin of life through evolution is “ripe for displacement” and it represents “a heroic triumph of ideological theory over common sense,” which will be seen as “laughable” in a couple of generations.
>Its main failing, he argues, is it fails to account for how consciousness fits into the natural order. Instead, it regards it as an afterthought, an accidental quirk, a trinket on the tree of life, less important to life’s story than the random physical mutations of genes.
>By putting physics at the top of a scientific hierarchy, he argues, modern Darwinism offers a dogmatic system of thought that is intoxicating precisely because it offers the illusion of freeing us from religion.
>“For a long time I have found the materialist account of how we and our fellow organisms came to exist hard to believe, including the standard version of how the evolutionary process works,” he writes in the book, which is subtitled “Why the Materialist Neo-Darwinian Conception of Nature is Almost Certainly False.”
>“I realize that such doubts will strike many people as outrageous, but that is because almost everyone in our secular culture has been browbeaten into regarding the reductive research program [about the origin of life] as sacrosanct, on the ground that anything else would not be science.”

How accurate is this?
Why did they choose this ratio and not the inverse??
If I say "If you take 5 times the active dose you die", or "If you take 100 times the active does you die", this makes sense. But with 0.2 and 0.01 nobody can quickly get it.
>>8585825
If you take 0.2 times the lethal dose you don't die

Because this way it makes the graph more intuitive so damage extends along both axes
So here is something I've been wondering. One of the biggest things which sunk infinite universe theory was Olbers paradox, which in a nut shell states that if the universe was infinite, then there would be no dark space in the night sky since in every direction would be a star, but reading into general relativity one has to acknowledge that it is actually possible to apply infinity into calculations (as this explains black holes), which removes infinity as being an illogical number, and due to black holes it is known that light is actually effected by gravity. With this one could assume that at a certain distance light emitted by a star would be shifted due to moving such a vast distance, while being pulled by gravity transferred on to it by dark matter.

The reason we don't see an infinitely bright sky from infinite stars around us is because those stars have not been around us forever, they have only been around us since the Big Bang, which is not enough time for their light to reach us. The reason we don't see an infinitely bright sky from the energy of the dense universe of the Big Bang is because that light has been so redshifted by the expansion that it is only visible with microwave detection. So the "paradox" means that the universe cannot be static, it has nothing to do with it being infinite.
>>8585796
Thanks, that's not really what I was asking, but that's my fault for not articulating the question very well.
>>8585796
>Let me try it another way
Let's say that if we where on a fixed point, would it be possible for a fixed light emitting object to be so far away, that the light does not reach us, due to gravity slowly altering it's course?
Is this true? I watched the Numberphile video but it still baffles me. Could an anon explain?
First, this is literally the most obnoxious maths mene and notation abuse ever devised by humanity.
Second, Numberphile's "proof" mistreats divergent series and basically isn't a proof at all.
You should check out Riemann's functional equation and how it's used to construct Riemann's zeta analytical continuation.

The video is long, but very well made and explain all.
To sum up :
In the domain of real, 1 + 2 + 3 + ... does not equal -1/12. The main argument used by numberphile (that 1 - 1 + 1 - ... = 1/2) is false, because you can just arbitrarily change the order of the terms of a sum that does not converge.
However, the function defined by [math]f(s) = 1 + 1/(2^s) + 1/(3^s) + ... [/math], more known as the Zeta function, can be artificially prolonged outside of where it exists.
When you uses this prolongation at the point (-1), then you have [math]f(-1) = -1/12[/math]
That does not mean : [math] 1 + 2 + ... = -1/12[/math] ; the sum [math] 1 + 2 + ... [/math] does not exist, mathematically speaking. It is infinite. However, we can artificially extends f in a way that f(-1) = -1/12.
>>8585801
>notation abuse
Classical analysis shouldn't have the monopoly on those symbols
It's notation out of the context of more relevant math, but there's no abuse. If I use [math] \omega [/math] to denote both a rotation vector and it's magnitude, then that's abuse of notion. An equation from some context that also has an interpretation in a more common context isn't abuse..
Hey there scientists, /ck/ here. Have there been any breakthroughs in food science recently? Also: how far are we from making "meat" (I guess like mushroom or corn based) that equals or surpasses the nutrition in real meat? I'd love to go vegan for the environment, and I know that flavor is getting much better, but I'm worried about important micronutrients like b-12 and omega 3 that you can't really find in plant sources.
>>8585724
just take the b12 pill and algae oil capsules.
Looks like you fell for the environmentalism hoax. Sad!
>meat that surpasses real meat
We won't ever do that. If we do it won't taste like real meat. It's going to be a tasteless nutrient slab.
It's more likely we genetically engineer animals to produce more meat per amount of feed and water we give them so they shit less. A humanitarian effort would also work on genetically engineering the animals so they don't feel pain at all, and are pretty much brain dead biomass cultivators, but that might be more effort than its worth.
