Well /sci/ after all we are animals. Mammals.
I grew up watching animal kino on Discovery and Nat Geo but still didn't realize most of that shit applies to humans as well.
What are some animal instincts things humans do? What are some animal behavior human females do to attract a mate? What are some of our animal tendencies people delude themself don't exist because we are humans?
No political or incel shit. I want a purely scientific discussion.

Disgust is something a lot of people don't really think about. Why is the sight of a naked man *disgusting* rather than anything else? The need to lash out is very animalistic, too. Honestly, most things people do just makes me think of animals. Not necessarily negative, but I do abhor the refusal to acknowledge this truth.

It's not really strange. Math in the way we know it today is tied with Europeans like Euler, Newton, Lagrange, Laplace (say 1600-1800) before the age of specialis and formalization kicked in. There is lots of important earlier maths associated with Greeks and Arabs, even if we may not know many names. The French revolution happened, England and the Dutch dominated the work for a while, and the famous people we know most hence are from that time.
I can also tell you names of Brazilian and Japanese mathematicians etc, but they just came 100 years too late to be in the modern basic bitch Engineering canon today.
So like with many things, look at the invention of Capitalism and the Dutch East India company and people who affected the modern world as you know it come from that time and onwards.

Science doesn't progress.

SCIENCE
Is a process.

We do science, science doesn't do without us. Saying "science progresses", is like saying "I built a robot and it progressed". Therefore science is not some conglomerate that progresses alone.

Stop saying "science progresses" or anything like that. It's making me stupid.

"Gravity" =/= "things go down". "Gravity" is an abstract concept based on a fuckton of notions that you take for granted but are actually bizarre, like magical, invisible "forces" exerted by some vague concept of "mass" which causes a change in the rate of change of "displacement".

he Time Travel Interpretation of the Bible

Abstract
We describe the Biblical work of ages as a time travel program for saving humanity from extinction. God's existence is proven as a consequence of the existence of time travel, which is supposed. We present the case that Abraham's grandson Jacob, also called Israel, is Satan. We make the case that the Israelites are described as God's chosen people in the Bible despite their identity as the children of Satan because God's Messiah is descended from Abraham through Satan. They are chosen as the ancestors of the Messiah rather than as Satan's children. We propose an interpretation in which God commanded Abraham to kill his son Isaac to prevent Isaac from becoming the father of Satan. We suggest that God stayed Abraham's hand above Isaac because preventing the existence of Satan would also prevent the existence of Satan's descendant the Messiah. The history of the Israelites is summarized through Jesus and Paul. This paper is written so that the number of believers in the world will increase.

So the main problem with fossil fuels is not pollution or global warming or any of that crap, the main problem with them is that they are finite and we will run out of them rather soon (1-2 centuries I would say).

Right now human civilisation is built exclusively on fossil fuels as an energy source. Nuclear/wind/solar are gimmicky bullshit fads. They exist solely on govenment subsidies, they are not profitable, they have scalability issues, they require fossil fuels to set up and to operate and most importantly, their output to input energy ratio is very low compared to fossils.

Because energy will become more and more expensive as time goes on, humanity will slowly decline and revert to pre-industrial state. Technological progress requires a lot of cheap energy and that is gone forever, meaning technological progress is mostly over, we will never have a significant QoL improvement ever again, we will not invent AI or fusion or travel space.

It's very sad and I don't want it to be that way, however it seems like this is our future. Is there anything wrong with my line of thinking?

Conventional oil and gas will last less than 50 years cheap. It's all about cost and return of invested energy more than "reserves".
Unconventional gas could last 200 years max, but not exactly an easily available source.
Coal actually is relatively scarce.

>humanity will slowly decline and revert to pre-industrial state.
No, the reversion from pseudoindustry (Romans) to pre industrial isn't because of energy price. With current tech the max reversion would be 1920 to 1950 but with better efficiency.
The most affected things would be conventional (concrete) construction, steel (right now steel is 5 times cheaper than meat) and air transport. Also common transport but that is easier to make efficient (like post-war small and slow vehicles).

Wind and biomass have far more potential that thought although it would require huge political and economic changes as most of the energy is in the southern hemisphere.

Unironically nuclear fusion is probably useless and nuclear fission in its current form us scarcer than oil (less than 0.3% of the uranium is used, thorium is a meme).

Minerals are other problems unsolved and probably worse than energy.
