I'm insulted, frankly.

No, its currently a cheap and relatively healthy caffeine vehicle with lots of historical acclaim.

Hell, when Coffee and Tobacco came to Europe, Europe soon after began the enlightenment and the industrial revolution.

Coffee is great and probably caused the enlightenment. Your sleep patterns are meaningless.

>>7770758
please explain how coffee "controls" society. As you suggested

You could teach a 5 year old the algorithms behind it.

He would most likely need a cheat sheet but he could do it.

>>7770762
I mean actually deriving the algorithms yourself.
There's not much puzzle solving done when you're just given a walkthrough, right?

Do you mean "deriving the algorithms" on the fly or implementing the algorithms on the fly? Because on is possible but not the other. One is also dependent on the other. One takes hours, perhaps hundreds of hours for a noob while the other would take minutes, perhaps even seconds but most likely minutes.

>Kripke was labelled a prodigy, having taught himself Ancient Hebrew by the age of six, read the complete works of Shakespeare by nine, and mastered the works of Descartes and complex mathematical problems before finishing elementary school.[4][5] He wrote his first completeness theorem in modal logic at the age of 17, and had it published a year later. After graduating from high school in 1958, Kripke attended Harvard University and graduated summa cum laude obtaining a bachelor's degree in mathematics. During his sophomore year at Harvard, Kripke taught a graduate-level logic course at nearby MIT.

Dude, just walk up to that unproven analytical philosophy conjecture and, like, be confident lol. Works every time bro!

[math] \int\limits_\mathbb{R} {{e^{ - {x^2}}}dx} [/math]

>>7770664
Note that this (and many other integrals) can be determined using dimensional analysis. I recommend the book "Street Fighting Mathematics" (its free google it) for that and many more useful techniques.

>>7770659
[math]\int{ \frac {(1+x^2)dx} { (1-x^2) \sqrt {1+x^4 }}}[/math]

Not an easy integral.

When we do a wick rotation, i.e. using an imaginary time coordinate [math] {t_E} = it [/math], the path integral we use to describe a theory will become a euclidean path integral. [math] \int {\mathcal{D}\varphi {e^{iS\left[ \varphi \right]}}} \to \int {\mathcal{D}\varphi } {e^{ - {S_E}\left[ \varphi \right]}} [/math]


This allows to equate a QFT with a quantum statistical mechanics theory as the path integral takes the form of a partition function. The euclidean path integrals tend to me easier to evaluate and diverge less.

Well, consider how we view the universe.

We see a three-dimensional world with one dimension of time, seeming to move unilaterally from start to finish.

In order for Hawking to be able to imply that the universe had no beginning or end, he simply suggested that maybe TIME has an additional dimension orthogonal to the time we perceive.

If time is shaped how we think it is, then imaginary time, according to Hawking, would be spherically-shaped. This implies that the universe has neither beginning, nor end.

Topics that are actually about science that get answered correctly without anyone getting called a faggot or diverting into far right political rants. Boring.

>>7770481

There's a smugness and fake sincerity pervading the whole place. At least here people are honest about being egotistical cunts that need to constantly categorise people in categories of superior and inferior, of which they themselves are in the former, during every moment of every day.
