This student died after taking LSD - https://www.thesun.co.uk/news/3366552/british-gap-year-student-lsd-death-canada-hallucination/ (apologies for the sun)

The article mentions he had 1.3micrograms in his system for every microlitre of blood, which would mean he had around 6,000,000 micrograms of lsd in his sytem, am I missing something here?

It is so sad that pi was derived and used as the basis of calculating circles and not tau. Area of a circle tau squared over two. In other words it is the integral of the circle, and tau lays out the method of integration. The greeks might have figured out calculus if they used tau.

Say, charging your phone while you walk next to power sources?

Would there be any health concerns?

New /sci/ meme.

But seriously holy fuck linear algebra I is fucking exhausting. The proofs are easy and interesting but the first two components of the course are "matrices and determinants" and "systems of linear equations".

At least we are almost done with this component and the next is vector spaces which means matrix hell stops now.

his quote:
>
The idea of man-made climate change is silly. Here are a few reasons why:
The Gulf of Mexico sends more CO2 (the hobgoblin of choice for climate alarmists) into the atmosphere on its own every year than all of human civilization. If you consider how much of the planet is covered by oceans and compare that CO2 output to our own on a pie graph, our contribution would look like a straight line drawn with a very fine-tipped pen.
The world's ecosystem consumes as much CO2 as it can touch. More CO2 means trees grow larger and faster, therefore expanding their capability to process it. Also, trees are capable of processing far more CO2 than they currently have access to, so it would require a massive increase from current levels for the existing forests of the world to notice a change.
The earth underwent periods of warming and cooling in ancient times, well before human civilization had developed, and some of those periods were more severe than any we've seen in modern times.
The earth's climate is driven by energy, not the kinds of molecules we have floating around us. All of the planet's energy originally came from the sun. It provides heat. It nourishes plant life. It infuses matter with energy, allowing it to exist in fluid and gaseous states. The sun fluctuates, and every time it does, we feel it in our weather.
Climate science is used as a political tool, and therefore cannot be trusted, especially after UN researchers were caught red-handed falsifying data.
I'm in the southern US, near the edge of the temperate zone where winters are usually somewhat mild. This year, winter weather for my area ended in April and began again in November. If the planet is warming, I sure can't tell.on-climate-change

Does the gulf of mexico really have an output of co2 that is greater than all of human civilization?

>Abstract

...

We hypothesized that plasma of an early developmental stage, namely umbilical cord plasma, provides a reservoir of such plasticity-promoting proteins. Here we show that human cord plasma treatment revitalizes the hippocampus and improves cognitive function in aged mice. Tissue inhibitor of metalloproteinases 2 (TIMP2), a blood-borne factor enriched in human cord plasma, young mouse plasma, and young mouse hippocampi, appears in the brain after systemic administration and increases synaptic plasticity and hippocampal-dependent cognition in aged mice. Depletion experiments in aged mice revealed TIMP2 to be necessary for the cognitive benefits conferred by cord plasma.

We find that systemic pools of TIMP2 are necessary for spatial memory in young mice, while treatment of brain slices with TIMP2 antibody prevents long-term potentiation, arguing for previously unknown roles for TIMP2 in normal hippocampal function. Our findings reveal that human cord plasma contains plasticity-enhancing proteins of high translational value for targeting ageing- or disease-associated hippocampal dysfunction.

Why do we need to check if x = w? Why?

If on input <M,w> we create a machine Mw that simulates M, why do we need to check if the input to Mw is w? Mw will ALWAYS check if w = w and it will always be true, for all inputs possible

I don't understand this. I mean, why check something that is by definition true? We construct Mw when we need to use it to check M on w, of course Mw will be given w and of course x = w.

It's like saying:
>I'm going to create an equation that has a solution of {2}
>that equation is x - 2 = 0, i'm 100% sure it is
>wait, first let me check if it has a solution of 2
>2-2=0, yep, it does work, thank god
what?

36 year old brainlet here. Is there any hope of self-learning computer science and math as a hobby at this age?

I tried some Calculus courses and it was pretty easy to understand. So I'm not completely retarded, right?
