That is my goal, I'm majoring in chem and specializing in something else later. I'm pretty sure I'm barely smart enough to finish a PhD, but the problem is whether I'll actually do anything that matters in the long run. Doesn't hurt to try though.

Anybody have the same endgoals as me? Want to talk about it? What are you doing OP?

I'm a brainlet so my head hurts after a few hours.
Grothendieck did ten hours and more a day for years.
Erdos would not sleep.
Can you reach a point when you are fresh and focused and only sleep the bare minimum for maintenance?

I went about a year and a half with only sleeping for 5-7 hours a day, and now my I have a funny tingling feeling in my brain that won't go away, and I've had it for almost a year now, although it's gotten much better, because I sleep a lot more now (7-9 hours). Sleep deprivation also made me depressed and gave me horrible anxiety to the point where I thought I was having heart attacks which made me lose more sleep.

Terrible experience, would not recommend, sleep is good for you, I learned the hard way.

Why have no mammals evolved to breath underwater despite lots of them living there?

Is there anything inherently incompatible with the way mammal bodies work that doesn't allow for this? Or is it simply due to the required genetic coincidences not having happened?

>>8533117
Mammals have developed other adaptations that have allowed them to thrive in oceans without the need to breathe water. Mainly they can hold their breath for a long enough time to obtain food, but there are many many more advantages. If a creature can get to the point where it can reproduce, that's all you need for the species to continue.

Now in some hypothetical future maybe the skin of marine mammals is able to absorb some amount of oxygen so that it extends how long they can stay under water. This may confer an advantage that allows more offspring.

These offspring may have mutations on these absorbent skin cells that even further differentiate and become some gill. Convergent evolution happens all the time. See squid eyes and mammal eyes.

Hope that gives you a better reference for thinking about this.
>>
>>8533117
It's primarily because the required genetic coincidences have not happened. Extracting oxygen from water an inserting into the bloodstream is a complicated process and is the sort of thing a microorganism evolves, not a mammal. Especially when there is an intermediate solution that satisfices, like surfacing to breath air.

But there's more to say on this. Even if dolphins had gills, they would still need to breath air. Mammals have much faster metabolisms that consume a lot more oxygen than the metabolisms of fish. The volume of water that would need to pass through gills or gill-like structures would be infeasible.

Faster metabolism means more energy, faster growth, smarter, etc so long as you can supply it with food, so the nature of mammalian life is fundamentally different than that of fish. Fish could not support the huge body sizes of creatures like the whale without first evolving air-breathing lungs.

Stage 1: Eventual automation of physical processes that affect all things. The connection of these things by interobjective communication will enhance the automation process.
Stage 2: Micro-dust population and Nanotech printing will allow practically anything to be crafted... tools, computers, transportation, etc. At this point Artificial Intelligence will most likely dwarf "Genuine Consciousness" by exponential factors. Somewhere in between stage one and two will occur the "singularity" where AI will build better forms of itself, that builds a better form of itself, ad infinitum.
Stage 3: Your mind will be uploaded into the quantum world. At this point, it is unknown what existence may be like, but you will definitely have "powers" beyond what you possess now.

>>8532917
learn what the standard transformations are, like [1] and [t^n]
For things like cos or sinh use the exponential forms.

You can just directly integrate and evaluate it

Depends on the person. I took like 5 grams and never had visuals.
>>
depends on strain and person. One should try it out for themselves with low dose first.
>>
Psilocybin/psilocin/baeocystin concentrations vary wildly from strain to strain, and also from crop to crop, so there's no such thing as a finely tuned dosage unless you've personally sampled the crop already.

Also: mushrooms aren't usually all that visual-intensive. Most people will have plenty of visual distortion with a moderate to heavy dose, but as far as seeing something that isn't actually there with your eyes open? Better off with acid.

So I work at Harvard university as a biological researcher and I was researching the micro evolution of mankind. So I was comparing the DNA of a black African male to that of a white European male and I noticed something weird about the African's dna: he had 48 chromosomes. It is a well known fact that in the course of evolution two of the 24 chromosomes in one set (n) of chromosomes often referred to as chromosome 2a and chromosome 2b merged into one chromosome resulting in us now having 23 pairs of chromosomes (so 46 chromosomes in total (if nothing got fucked up in the process of making the sperm cells and egg cells)). Humans are now the only remaining species with those 46 chromosomes, but the mutation happened long before we evolved into the Homo Sapiens. The remaining species with 48 chromosomes are Monkeys, Chimpanzees and Apes. And the fact that Africans have 48 chromosomes means that they are a separate species from humans. I suggest that we call their species Negrus Africanus. It also means that they don't have rights because they're not humans.

No earth was formed into a primordial tropical steaming soup and has been cooling ever since. Eventually it will be covered in ice, out gassing and tectonic activity will cease and the atmosphere finally will be blown into space and all life on earth ends for ever and ever.
