Boring example, and it gives people like the other guy the wrong idea about math, the same kind of people who hear about "incompleteness" and then start saying how we don't know 2+2=4 etc, which is all cool until the rest of us just kill you with working tech lol.

A 3 dimensional complex vector field doesn‘t exist because imaginary basis elements are bivectors of hypercomplex basis elements. The vector space generated by two hypercomplex bases contain the usual imaginary number field, but three hypercomplex bases contain the quaternions, necessarily generating a 4d complex vector space instead of 3d.

Cantor's Diagonalization argument, godel's incompleteness theorem, very fun philosophical implications to these.

In terms of being profound for its use in conceptualizing nature or even simply making more math questions answerable, Fourier Theory is EXTREMELY underrated and I feel like many undergrads go their entire experience without grasping just how beautiful and useful it is. There are other things that accomplish something similar, taylor series, bezel functions, legendre polynomials, etc, but something about Fourier using sines and cosines (and their inherent connection to waves) has made my understanding of physics feel far far more profound than it would've been without it

https://en.wikipedia.org/wiki/Tarski%27s_undefinability_theorem

This is a much stronger result than Godel's incompleteness theorems. Profound implications for formal systems and mathematical logic

Omicron is looking to be the worst wave in the evolution of coronavirus

1. We have the highest rate of growth seen in South Africa, including % positive.
2. We have unknown severity in a young, relatively healthy, highly prior infected and 25%+ fully vaxxed population

The low average age of those affected so far is probably masking severity and the speed of spread is also hiding it due to lag. There is no reason to believe Omicron will not be the worst wave of the entire pandemic. In fact all signs point to it being the worst wave.

The public is being silly right now in not pivoting to maximum defensive measures. Similar events happened in 1918 pandemic when the later waves really ripped through places like San Francisco after the populace got "bored" of being safe.

HELL IS FUCKING COMING WORSE THAN EVER

> demonstrate that the vaccine caused the lethal heart damage is a fool's errand
How? It's already known thay mRNA vaccines can cause myocarditis, if the number of deaths in young people was to go up in the following years it would probably be because of that

Stop thinking. Get vaccinated. If one vaccine doesn't work, get vaccinated again until Doctor Fauci says the pandemic is over.
>>
>>13940232
>if the number of deaths in young people was to go up in the following years
Which is completely different from determining "direct deaths from the vaccine years later". Sure, what you said is true, but the original goalpost was about the vaccine killing people in the future IN GENERAL, including people who were still hale and healthy at the time of vaccination but stopped being so later, people who were heart-unhealty to begin with, and, oh, the middle-aged and elders.

Scientifically speaking, is this thing a meme?

That's a good thing anon. Before I proceed,I should preface this by saying I'm Indian. We don't have a grading curve system here, so we rely on percentages. 80 is typically the highest, and if I didn't get higher than 75 (again, really fucking hard), I would have to face the wrath of my parents. Now I'm in research, the perseverance is paying off.

In South Carolina the requirement was precalculus minimum to graduate. Calculus I could be substituted by probability and statistics, which most people took, as anyone taking calc I just took AP Calculus which was only offered the first semester. Second semester AP calc required students to take it at the local community College.

I don't find it surprising that a shithole like California has such low standards. In my experience, it seems very liberal states are the most likely to have POC students all go to technical highschools and limits their chances at university. This is the case in most of the northeast states like NJ and NY. Good highschools require middle school "students"(parents who care) to fill applications like college, and find their own method of transportation as the busses aren't going to go all over the county to pick up stray kids. Even at the middle school level, liberal states and cities set up immigrant and non-white neighborhoods to fail, with insanely low standards. When I was a new immigrant child in Newark, they were teaching times tables in 7th grade. In the middle of my 7th grade school year I transfered to South Carolina and they were going over algebra.

Southern states are desegregated by law, and the gated neighborhood kids go to the same school as the poor trailer park and low income housing kids.

Math education isn't racist. State level administration in liberal states is filled with racists who want to make non-whites unskilled slave labor with no opportunity to work their way up.

It's a self-replicating machine created by pure chance through chemical reactions.
