>which they already are mostly
until they aren't, like every single time they weren't.
The cool thing about mega death by super volcanism is that it will be agonizingly slow, in two respects. As a species and as individuals. Firstly, its a very slow process, a volcano will start chugging out toxic fumes over hundreds of years, and then another, then another, in a process that could take thousands of years to kill off most life on this planet.
And even if we are completely aware of what is happening there will be ABSOLUTELY NOTHING we can do about it! *chuckle* Imagine that! Knowing your entire species is fucking doomed, along with anything else bigger than a single cell, and being utterly helpless to prevent it! *snorkle!*
Then secondly, when the toxins reach unbearable levels, after many generations of watching life expectancy and general quality of life decrease we will resort to all sorts of desperate measures, NONE OF WHICH WILL SAVE US! *guffaw!* People will watch their children die while they find it more difficult to breathe with every passing day, as the filtration systems fail and the last vestiges of civilization fall into savage barbarism before the last inevitable extinction! *lololol!*

>I have got to do something different with my life, anons.
Lol I’m in a math program, with the same feeling—like I should try for medicine, at least I would be helping people for once. Anyway, khan academy is a great start. Other things that come to mind
> https://www.edx.org/school/mitx
These are online intro university courses from MIT. They are free (but they nag you to upgrade to a “premium” version). There is a schedule, with online lectures, homework due dates, and a functioning online grading system. I like this because its lectures are very good and it imitates the structure of a real course, which hooks into your brain a little better than
MIT’s older online courses. These are good, just less polished and less advanced in terms of user interface, and without the enforced structure
Computer programming and math and closely related skills

Anyway even if you do stick with healthcare, it is always a good thing to learn something on the side. Studying out if interest is one of the easiest hobbies out there other than beer and video games, and obviously a lot better for your life
That's what happens when you fall for the pure math meme without being equipped with enough schizophrenia and autism.
Appreciate it, anon. I was half expecting to get shit on for asking here so thanks for the genuine info. But yeah, good chance that I do end up sticking in healthcare because it’s definitely not a bad place to be, but either way I’m going back to school and need to brush up on my math regardless. Also I’m finding it to be weirdly enjoyable.

What the fuck is vitamin D even doing to me? I thought it was just calcium?
Am I really so deficient that I'm passing out after missing 1 day of my dose?
I was concerned I was taking way too much vitamin D, but will I need to consume this shit forever? I thought the body was supposed to produce it naturally?
It's not a miracle but I have noticed the affect on my mood, I am exercising 10% more... from 0%.
How do I know when I'm getting too much because I looked it up online and it said too much can cause diarrhea and calcium stones.
If you were prescribed a dosage of 20k then yeah, you must be really fucking deficient. A normal regime would last a few weeks or months. You'll be fine if you keep to that.

Can anyone help me identify this organism? I know I've seen it but I'm drawing a blank. Doesn't need to be the exact species, even the order would be fine.
A professor told me there are Chinese manuals with problems from specific universities for PhD qualification exams. Where can I find them?
Assuming there is an "island" of stable superheavy elements, and assuming they can only be naturally produced in meaningful amounts during stellar events like supernova, would they have a tendency to sink to the core of planets during accretion?

Does the atomic heaviness of a small amount of an element matter that much when thinking about how it interacts via gravity/density on a macro scale?

Nutrient found in beef and dairy improves immune response to cancer

plants that grow faster due to growing in a CO2 enhanced environment also root deeper, which means they have access to more soil micronutrients in a CO2 enhanced environment

how did that happen if CO2 is really a greenhouse gas?
Because CO2 isn't a greenhouse gas.
Yep, it basically makes plants obese.

>The catholic church tried to kill scientific progress
Galileo's entire career was funded exclusively by the church. So was Copernicus's. Galileo was only prosecuted because he was too much of a sperg to wait for higher powers in the church to review his findings before proclaiming them the one and only truth.
And as it turned out Galileo was completely wrong about his assertions with respect to where "the center of the universe" is. Geocentrism and heliocentrism are just the same phenomenon explained via two different coordinate systems
The industrial revolution was related but separate. The cause of the industrial revolution was specifically the textile industry.
It's always the environment
Not to mention religions writers and artists were enamored with the idea of heliocentrism once it got going, and you can see its influence in works like the Divine Comedy.

People who go through life presuming they're some sort of unique special snowflake genius mostly deserve to be killed. Having those kinds of delusions of grandiosity is a primary characteristic of narcissistic personality disorder
