For the record, I think I should have it pointing into my room. I figure that the air will be coolest lower down outside my door, and forcing that air into my room will help the most, but I don't know if that is helpful with the AC also blowing into my room

since you dont have a source of cold air input, only heat input (computer + sunlight and hot air from outside) you'll want to have the fan blowing cold air into your room

blowing the air out wont help since new hot air will replace it immediately.

blowing cold air in will reduce the temperature of the hot air in your room

>>8093024
oh i missed that you have an AC vent. then what you could try is positioning the fan over the AC vent so it passes that cold air better through your room.

i tilt a small desk fan over my AC vent so it isnt blocking the grate and it blows cold air all through my room, whereas with the vent alone, it just hovers around that area.

since you have a lot of heat sources this would probably work best, and just leave your door open for air circulation

Because if you dont study youre gonna end up like the guy who picks up your trash every week and barely make enough to support yourself.

Looks like the product rule of differentiation...

Let a = b = 1/2, f(x) = 1. Your welcome.

>>8092982
Good one, I didn't think of that.

Now suppose a and b are real numbers not functions.

>Forget a fact? Write what you know, get part marks, and move on to the next question.

Biofags really due enjoy their word vomit, don't they?

>>8092954
>Forget an equation
It doesn't matter if you forget the equation. You can always derive it.

>>8092954
I am not going to lie, there is some memorization in math. A lot of the times you need to memorize postulates and the most immediately useful theorems so that you can do anything.

The difference between bio and math is that the things you memorize in math there is a sense of logical continuation. Many propositions immediately follow from another so as long as you are sharp and remember just the fundamentals, you can come up with the rest.

In a recent test of set theory that I took, to prove a proposition I needed to use a tautology that at the time I did not remember was given to us. I constructed the tautology that would make the proof possible and then made the entire truth table for it, calling it a lemma, and then finishing my proof as an immediate consecuence of the lemma.

Then I checked my notes and that was one of the first tautologies we were ever taught.

However, if you forget what is in the left side of the heart you cannot take one of your classmates and fucking dissect him there to find out. You absolutely need to know that or else you are fucked forever, as you will never be able to derive it.

If you are asked to name something, you will never be able to derive the train of thought of the biologist from 300 years ago who named it, you better remember that because you will never derive it.

fear of the unknown

>>8092956
But why? At least in my circumstances, it's completely irrational. I'd accept it as a phobia, yet I can't pin any environmental factor or traumatic event that would cause it.

Also, it seems to be a somewhat common fear.

>>8092978
uhh of course its common its the like the only fear all humans have. And it makes perfect sense, Going into an unknown is dangerous, especially when it's nearly pitch black, plenty of evolutionary reasons for it to be bred into us.

The second law of thermodynamics indicates the irreversibility of natural processes, and, in many cases, the tendency of natural processes to lead towards spatial homogeneity of matter and energy, and especially of temperature. It can be formulated in a variety of interesting and important ways.

It implies the existence of a quantity called the entropy of a thermodynamic system. In terms of this quantity it implies that

>>8092640
Causation is just another word for correlation.

Example 1:
We observe that smoking and lung cancer often appear together. Therefore we conclude that lung cancer causes a greater appetite for cigarettes.

Example 2:
We observe that climate is changing. We also observe that humans are doing things. Therefore climate change must be caused by humans and has never changed before humans influenced it and anyone who disagrees with this truth is a dumb evil republican capitalist who knows nothing about science, statistics or common sense.

none of them.
Ethics has destroyed science, and no one can come up with revolutionary stuff like einstein did.
As long as scientists will be constrained to work in one field by the richest universities, no good science will come out of it.
Too bad the french universities and schools are too small to be relevant. At least they produce polymaths, but science doesn't pay enough to interest them.

For that time period? 3D printers might actually reach a milestone.
And the thing it brings to the table isn't just cheap, its insane.

Currently its a expensive plastic novelty.

Thanks. The definition of gamma is listed in pic related. Second to last equation on the right. This is all the information that the authors provide.

>I've checked the wikipedia and there is a page with a short list of so called "hypercomputers", i.e. models of computation more powerful than Turing machines, but for some reason none of them seemed to have gained any popularity. Why?

Because, while novel and cool, they rely on science which isn't yet entirely understood?

Was that a real question?

>Considering that neither quantum mechanics
What do you mean? Quantum mechanics IS computable. It is not deterministic, but that doesn't mean it can't be computated probabilistically.

>nor consciousness
So you are saying that a brain is a hypercomputing device? How? Its a purelly physical system that doesn't seem to rely on any quantum shenanigans and so.

>none of them seemed to have gained any popularity. Why?
Because none can be built, nor aproximated to arbitary usefulness (unlike turing complete machines)

>>8091928
They're not even that novel. Turing himself already thought about the possibilities.

If research in hypercomputation became more popular, maybe we'd find out how to do it, instead of wasting too many resources on questions which in comparison appear useless (e.g. P=NP).

>>8091935
I posit that neither the collapse of the wavefunction in QM, nor the creativity of human consciousness are algorithmically computable by a Turing machine. They are strictly stronger.
