How do I make a computational model of a fission reactor? What is the best level of abstraction for acquiring a wholistic view of the operation and function of a reactor from the fission reaction through to the electricity generation by a turbine?

Are speed reading techniques worth it? I will not use it on math and physics books, but simpler stuff like Novels.
There's information claiming it to be false, for instance this:

im kinda retarded
had to move a lot as a kid, didnt get to focus on school all that much, and then i went to a school with unironically more difficult maths than anything ive seen before (different country). i get mad at myself for not knowing maths well and screwing basic calculations over, so, is there any site or any resources I can browse to grow some grey mathematical matter? first time posting on 4chan btw
🧵 Should We Terraform Mars?

>A desert moss could be the key to terraforming Mars, according to a recent study published by Chinese scientists
>Due to its extraordinary resilience, Syntrichia caninervis (S. caninervis), a moss found in extreme desert environments from Tibet to Antarctica, has been touted a "pioneer plant" for establishing a livable environment on Mars. Basically, scientists believe this plant could enrich the planet's rocky surface to enable the growth of other plants
>The scientists subjected whole S. caninervis plants to conditions typically found on Mars: high doses of gamma radiation, low oxygen, extreme cold and drought. They report that the plants could withstand combinations of these conditions, even losing over 98% of their water content and still bouncing back within seconds —"drying without dying” is the term that was used. Perhaps even more astounding is the plant's ability to recover and grow new branches after being stored in a freezer at −80 degrees Celsius (-112 degrees Fahrenheit) for five years or in liquid nitrogen (-195.8 degrees C; -320.44 degrees F) for one month
>"Unique morphological features of S. caninervis, such as twisted leaves, conserve water by minimizing surface area and reducing transpiration, and the awns provide efficient photoprotection from intense UV radiation, extreme temperatures and water loss," wrote the team. "Meanwhile, the cell wall, cell membrane, and chloroplast and its membrane structure remain intact even in a completely dehydrated state."
>Under stress, S. caninervis enters a state of "selective metabolic dormancy," strategically preserving key metabolites — products of cellular metabolic pathways — needed for its speedy resurrection.

I have to write a research paper in psychology and I'd like to denounce the NPC phenomenon. I can pick almost anything so it's hard to decide which aspect of the NPC phenomenon I could research and highlight. Do I go wide or specific? What defines an NPC? What are the specific symptoms I could focus on? Do I talk about the vaccine? So many questions, help me out a little please.

🧵 Why hasn't gene therapy exploded yet?
Anonymous at Thu, 11 Jul 2024 10:19:52 UTC No. 16277103
Every single individual has the capacity to edit genes in their own home using CRISPR kits and similar, and we have literally every concievable reason to upgrade our own software (namely, so we don't die or suffer). So with that being said, why haven't megacorporations and pharmecutical companies started openly researching and developing gene therapies like China has (or, at least, to the extent that they have)? I mean for God's sake, there is a man who lived with lactose intolerance all his life and CURED it, just with at-home gene therapy (linked below). This is a modern miracle, and the fact that we are not sprinting toward the further development of such technology when there are tens of millions of people born every single year hopelessly mentally retarded, physically deformed, or otherwise severely disposessed and suffering, is a massive moral failing of every country on Earth (other than China, who are seemingly the only ones who really breached these waters with no hesitation).

I am prescribed 300mg of lyrica and 250mg of tapendatol daily. Is this safe to continue taking for the next couple years? I'm already at the point where if I miss my lyrica dose I withdraw quite badly. My doctor says this is fine to continue indefinitely but it doesn't seem fine to me. What happens if I continue taking this for 10 years?

okay that's kind of an odd title. But now that Musk is creating these underground highways it got me thinking, wouldn't it be beneficial for us to have pods instead of cars? Think about how much effort we're making to make driverless cars with AI, wouldn't it be sort of a shortcut to instead of that, do pods like the movie logan's run
i think logan's run paints an elegant picture of how our future society could look like
cars are a big issue, think of how many starts and stops you have to make for all the pedestrians walking from street to street
i say we go turn to pods
I'd like to live in logans run

A recent study has exposed a method of artificially inflating citation counts through "sneaked references," which are extra citations included in metadata but not in the actual text of articles. This manipulation, uncovered in journals by Technoscience Academy, distorts citation metrics that are critical for research funding and academic promotions. The Conversation reports:
The investigation began when Guillaume Cabanac, a professor at the University of Toulouse, wrote a post on PubPeer, a website dedicated to post-publication peer review, in which scientists discuss and analyze publications. In the post, he detailed how he had noticed an inconsistency: a Hindawi journal article that he suspected was fraudulent because it contained awkward phrases had far more citations than downloads, which is very unusual. The post caught the attention of several sleuths who are now the authors of the JASIST article. We used a scientific search engine to look for articles citing the initial article. Google Scholar found none, but Crossref and Dimensions did find references. The difference? Google Scholar is likely to mostly rely on the article's main text to extract the references appearing in the bibliography section, whereas Crossref and Dimensions use metadata provided by publishers.

>Turing may have been a raging creep but he still did more for biology than every single biologist ever by predicting morphogens
>Natural selection is a roundabout way of saying shit happens because shit has a way of happening
>Biologists don't even know how to solve lotka volterra analytically because they don't even understand how to make reasonable assumptions
I'm a physicist and was worried about specializing in out of equilibrium thermo until I found out that mathematical biology was a thing. Biologists don't deserve the privilege of studying life, form and structure, they're too stupid to see past taxonomy.
Biologists would rather believe there is such a thing as recessive genes instead of figuring out that it's way more likely that precisely because genes are used primarily as mediators between other genes that the recessive genes are performing communication functions.
>Biologist sees a human
>Biologist sees a fucking shroom
>Biologist concludes the shroom is more complicated than the human solely because it has a longer genetic sequence
This is why you don't have a nobel prize for biology, this is why Mullins could get away with a nobel in chemistry for fixing your problems and why Prigogine and Schrodinger were better biologists than any crackpot "evolutionary biologist".
Either learn some math or shut the fuck up, biologists should be allowed to look cute in miniskirts and name bugs but nothing else.
