I agree, the climate has been quite stable for the past several million years and life has adapted quite well to said stable conditions. And far more importantly as I'm not some kind of Gaia worshipper I'm far less concerned with abstract concepts of "ideal states" and far more concerned with the climate humanity relies survival. As human civilization has only existed for about 10,000 years in a period significant stability, and we're entirely dependent on a handful of species of inbred plants which have been carefully selected to do well in exactly the conditions we're used to. To claim things will be better because of geologic records 10 million years ago. Has virtually no relevance and is just utter insanity.

Well sure but for most healthy people taking a few high quality supplements (vit b12, vit D) is going to be helpful. Most omnivores get deficient in B12 as they age.

I'm referring to the mindset people have where they believe they can eat whatever they want, take a multivitamin and actually think "yup, my body is getting everything it needs." In reality, high doses of synthetic vitamins can actually compromise your immune system, as the isolated compounds are seen as foreign invaders. It's nothing compared to the complex matrix of fiber and compounds that all vitamins are found in nature. Note I'm referring to plants. All essential vitamins are first created in plants (besides B12, D, long chain ?3s) before animals may eat them and do some biochemistry to them. (turn beta-carotene in retinol for example)

The cool part is you don't need to eat animals to get everything your body needs. :D

Literally all of them. Getting good at a field takes time, and there's not enough hours in a day to get good in every single area of math. Everybody sucks at something.
But natural talent is not so specific that somebody is going to be a natural wizard at combinatorics and at the same time be genetically incapable of passing a PDE class.
If you're good enough at math to excel in one field, you're good enough to not suck at any of them if you try.

The only story I've ever heard of Grothendieck embarrassing himself is the "lol 57 is prime" anecdote, which is a trivial little flub that gets blown out of proportion by redditors who want an epic story about how he was so le abstract he didn't even know any prime numbers.
Grootendick started his career as a functional analyst and then pivoted on a dime into AG and category theory. He's not a particularly good example of specialized talent.

Axioms are unprovable, yet all of modern math is founded upon them. You can’t build something truly great on a shaky foundation. Isn’t Science and Math supposed to be about objective, verifiable truths and not mere postulations taken on faith?

I'm going to bite. Okay here is an axiom for you. If I have an apple and another apple and I line them up side by side this is either 2 apples or apples that are next to each other. Obviously it's silly to say the latter but if you say 2 apples that makes sense. So from this axiom we can produce a result like 1+1=2 or for any object x+x=2x.
So axioms are things that are so painfully obvious that they don't need to be investigated further. Look at That one Euclid's axiom for geometry. It's says something like if I have one point here and one point there I can draw a line through thoughts points or connect them (I don't recall what it actually said). How would you go on about proving that? Easy! Take a pen, place two dots on a piece of paper in any orientation you desire and draw a line that reaches one from the other. Here's the thing, you seem smart so you know for sure that you don't need a piece of paper and pen to show this works. You can imagine it. That makes it axiomatic. So why would we bother proving axioms if we know that they work irrefutably?

Absolutely. The evolution of metabolism is guided by chemical realities. The simplicity and controllability of certain chemical reactions is universal.

This is an erroneous conclusion. A build rate could approach one nuke plant coming online every day even if one single plant takes a few years. You would just have so many in the pipeline being built that the finish rate matched what you needed.

Minor quibbles. Replacement reactors may not not require the same effort as fresh station construction: swap out the core.

Construction timelines could be sped up with effort to reach this goal.

This is going to sound ''out there'' but it is perfectly credible. We are on the verge of a revolution in space transport with fully reusable rockets and they can allow ultra rare metals sourced from space mining from sources such as asteroids to be a possible affordable option for replenishment of this vital material supply. Don't believe me? Wait five years and the space transport revolution will be readily apparent.

What nuclear needs is a state involvement model the coddles the research and development and deployment and massive investment of new next generation reactors that improve construction cost and deployment timelines and other goal objectives, and the current economic model that has propagated in the past 50 years or so of lesser state involvement for civil improvement ends in exchange for lesser tax regimes on the wealthy and the spread of ideology to support that objective by its proponents and believers thwart that critical support nuclear needs to propagate and prosper.

Does drug addiction actually exist? Obviously there are a lot of people who enjoy taking drugs, but we know from the teaching of Epictetus that 'feelings' are ultimately created in the mind, and that the mind has ultimate control over our sensations, and how we respond to them. Drug "addicts," therefore, are choosing to be that way. "Withdrawal" is a psychosomatic condition, similar to "chronic fatigue syndrome" in mentally-ill women. It's something that the user ultimately chooses to experience.

Given that fact, isn't the solution to drug addiction just to tell the "addicts" to knock it off, and to quit pretending? To jolt them out of their fantasy-world and back into reality, by demanding that they use their own minds to kill off the fake "addiction"?

Am I wrong here? I will clarify a bit - I accept that it's possible to die from a lot of psychosomatic ailments. Psychosomatic doesn't mean "fake" - it means that the source of the illness is in the mind of the sufferer. Change your thinking, change your condition. Non-psychosomatic illnesses are things like broken bones, or metastatic cancers, where outside forces determine the nature of your condition. Drug 'addiction' inheres in the mind, and is thus subject to resolution through purely intrinsic processes.

What’s 10% of 20 million for 30 days. But what ever number you get you add it to the Total then divide by 10%. So 1st day is 2Million so now you have 22 million then you find 10% of that ... but for 30 days.
