>The Dunhuang map or Dunhuang Star map is one of the first known graphical representations of stars from ancient Chinese astronomy, dated to the Tang Dynasty (618–907). Before this map, much of the star information mentioned in historical Chinese texts had been questioned. The map provides a graphical verification of the star observations, and are part of a series of pictures on one of the Dunhuang manuscripts. The astronomy behind the map is explained in an educational resource posted on the website of the International Dunhuang Project, where much of the research on the map has been done. The Dunhuang Star map is to date the world's oldest complete preserved star atlas.

Is it possible than our species or the evolution of our species in the very far future stop feeling emotions (love, fear, etc)?
I'm afraid about consequences of messing with natural reproduction and that it would lead to us stopping to reproduce with consequences such as the one I mentioned above.

How would natural selection react? Can humans survive longterm without emotions?
>>
>>13110101
Hard to tell but basically without emotions there is no reason to do anything at all. Nothing logical about survival.
>>
Quite opposite, everyone will cry about literally everything.

Which route will you take, anon?

I got my master's, going to grab 3 to 4 years of industry experience and if I hate it, I'm going for a PhD. That way once I complete my PhD (most likely at a R2 uni), if I cannot find a comfy small uni job to teach and do my own research, I can hop back into industry.

Now that the blue banana of innovative Germanics are being demographically replaced, where will the next innovation and research capital (per capita) be?

My bets:

The blue banana is based on cities that have a high urbanization rate with highly advanced economies contributing to a very high GDP per capita and innovation index. This is due to an early adoption of the knowledge worker model and emphasis on the production of high value products such as automobiles, pharma, specialized chemicals etc., but also financial instruments.

They are known as research centres because a disproportionately large number of innovations (high impact papers and patents) are generated there (just over half of all OPEC innovations today, and an 90% historically and over a quarter up until the modern tech boom in the USA). Almost everything else happened/happens in Paris/USA.
>>
>>13104079
why do presume the replacement ethnics will need further innovation? they have been content in thier civilisation have been stagnant in development for thousands of years.
>>
>>13109994
Literally this, without whites there will literally be no innovation, the chinese are incapable unless its stolen or reverse engineered, even then its of an inferior quality.
From the very first boats and ships to landing space craft on mars, no other peoples have even come close, they've had the same time to catch up too.
Today africans cant even build ships to such a design and quality like the ships built in the 1600s, they'll never reach mars or beyond.
No whites, no innovation. Stuck forever in a malignant status quo.
>>
>>13104079
some other region will emerge eventually, once our civilization collapse. just like before it used to Greece, middle east and China.

6/π2 ≈ 61%

Well, /sci/?
>>
You can't "pick a positive integer at random," since each integer would have probability 0 of being picked.

What you mean is that if you pick two integers uniformly from the range 1, 2, ..., N, then the probability that they are relatively prime approachs 6/π^2 as N approaches infinity.

But yeah, other than that, the math checks out.

I go to the kitchen to grab thing B. However, on the way to thing B also lies a thing A that I have to grab.
I can either grab thing A on the way to thing B, or grab it when going back after grabbing thing B.

I grab thing A on the way to thing B (option 1) because I know that it's better to grab the thing the first time I see it before I forget that I need to grab it.
On the way back, I no longer think of option 2.
Now, a question.
Is there a way to determine whether I didn't think of option 2 because I had no need for it or because I forgot about thing A (like I assumed I would)?

>>13098670
The need for A is what prompts remembering A in the first place, so I don't think so.

Is there something more imaginary than complex numbers? i.e we say that √-1 doesn't exist but cool stuff happens if it does, what about things like 1/0, going past infinity, a statement that is neither true nor false etc?

One thing you need to understand about mathematics is that it needs to be consistent to work. Any new axiom or definition that leads to contradictions instantly breaks math. Truth and falsehood lose their meaning and doing any kind of reasoning becomes impossible. Introducing square root of negative one leads to a consistent theory, so we can do it. Giving a definite value to 1/0 would lead to contradictions, so we can't do it.
>>
>>13109573
>Introducing square root of negative one leads to a consistent theory
*consistent theory where the usual rules of arithmetics hold (well, most of them)
>Giving a definite value to 1/0 would lead to contradictions

From everything I've seen, the laws of thermodynamics haven't actually been proven. We know that for macroscopic systems they should be essentially true due to simple probability. However, I haven't seen any proof that an atomic-scale device couldn't reverse entropy. While it's very unlikely that a random youtuber can create energy using magnets, it isn't inconceivable that a complex organic molecule or a small nanobot could reverse entropy. Hell, the proof that Maxwell's Demon is impossible relies on the assumption that the laws of thermodynamics hold anyway.

I'm taking Abstract Algebra this semester and so far Rotman's book has been good, it's both rigorous and easy to read. For practice problems I've been using Herstein's "Topics in Algebra".

As for introductory Linear Algebra, I'd go with Friedberg. It has a good balance of theory and applications and it's very readable. I think Shilov is a bit too dense. Hoffman it's a classic but probably a little difficult for a first course in Linear Algebra. Either way, it's always good to learn from different sources :)

What can I do bro/s/? I'm 26 and feel like my life is already over.

I didn't believe in myself when it mattered and now I feel I lost out. I was admitted to a program I wanted to go and chickened out because I was scared.
Should I go for the CS or math undergrad and graduate with 29? Or should I work first and code on the side?

I feel lost and thought we might get our own support group going on /sci/ because there might be more of us here.

PhDs are honestly overrated in their difficulty.

If you find a niche field where you can specialize, you usually don't have the same issues as in a Master's program, which is basically just studying a lot of different things, even if they're related.
