>Wasting 30 years of your life studying a meme degree.

But why?

>>7720238
There should really be a list of what is and what isn't a meme degree now.

>>7720244
The official list of meme degrees, as judged by all /sci/ posters:

>Non-meme degrees: my degree (if I am happy with my job), my friend's degrees
>Meme degrees: your degree, all other degrees, my degree (if I'm not happy with my job)

If you and I got the same degree, yours is a meme degree because you went to a meme university, or at least specialized in a meme subfield.

Sometimes, but I haven't really found it to be so.

Sleep deprivation facilitates deep and blunt honesty, and introspection. Though sometimes I suppose it can provide the means for inspiration, but lack the ability to really do much with it.

Sleep deprivation seems to shorten the mind's general processing chain, and the width of that chain as well.

>>7719662
What evidence is there for you to assert that sleep deprivation simulates "deep and blunt honesty and introspection?" Is this just personal experience? What do you mean by the minds "general processing chain?"

>>7719685
>What evidence is there for you to assert that sleep deprivation simulates "deep and blunt honesty and introspection?"
It's an anecdote.

I'm sure I could dig up some literature on fMRI studies showing a shift in what brain regions are most active during certain tasks, and as a general baseline, then extrapolate that to memory and reasoning, etc. Or observational studies, changes in brain chemistry / hormone secretion. All that. But it's just an anecdote for now. As I type this, I've been awake for ~26 hours. Done this frequently throughout my life.

>What do you mean by the minds "general processing chain?"
Can't really describe it. Means a lot of things at once.

Imagine a stimulus. Then it ripples and branches out. Eventually the reactions to that initial action are such a departure that they can be said to no longer directly relate. The mind is full of feedback loops and multiple systems working on various tasks.

When I say processing chain it tries to describe the whole of any given instant. You see something. You interpret it. You think what you think about it. You do what you do about it. Between the source and any arbitrary point afterwards, there is a chain of processing and changes in the mind that have accumulated. Width refers to how many branches, and how much evaluation and split offs and spillover occurred. Thoughts you might have suppressed, or diverted. Length means actual time, or amount between points you might see as distinct or meaningful.

A bit metacognitive, but that's as best as I can put it.

Civil Engineering is rather underrated. The problem with the modern discipline is that research has started to stagnate. The only active fields seem to be transportation and advances in material science propagating from other fields.

Let's not get started on the green architecture meme, optimizing heat exchange networks is not real research.

>>7719609
Eh, I'd say Environmental is doing fairly well nowadays.

what's aerospace engineering like?

no trolls pls

You can't jump directly to a grad CS degree unless your bachelors was in math or such

>>7719241
It would probably take me about a year to work up to the 300 level courses, right?

>>7719241
You can, there are many programs out there that let you in if you either have the mathematical aptitude, or are fine taking the prereqs to gtake the masters. In most situations I would just retake the BS in CS, although masters are more impressive

There is always fuckery afoot.

I'd like to resurrect Tesla so he could put the screws right to all you luminiferous aether deniers.

After unusual night, when he fired the sky above not only New York but also above all vast area of Atlantic Ocean during his experiment, Tesla suddenly left his laboratory without a clear reason and left all things untouched. As we know, he never crossed the threshold of Wardenclyffe, never visited it and never appeared on this territory. It was very strange, he didn’t take any calculation, drawing or document, none paper. It was a turning point in his public scientific work. He was living for 40 years continuously working, but he patented his mechanical discoveries only and published only the articles in newspapers.

>My question is "what about MACRO-evolution",

There is no qualitative distinction between "micro" and "macro." What some call macro is simply micro on a longer time scale. Thus your "for example" is not really an example of anything, but just a specific question.

>for example, how a specie can increase its number of chromosome ? An organism with this mutation, with one chromosome more, would be sterile, no ?

In most cases yes, but not always. Fusing or splitting a chromosome actually has very little effect on the genes themselves.

Because it's GREEN™! Nukular is bad coz Churnobyl.

Never mind the terrible energy density, rarity of materials or the environmental impact of mining them.

>>7716417
because they actually work.

>>http://www.sciencealert.com/rooftop-solar-is-now-cheaper-than-grid-electricity-in-these-6-us-cities

Because it's already cheaper than nuclear, despite nuclear being established. Graphene is the next generation solar component, and it can be manufactured out of methane, co2, glucose, and many other molecules.

Why don't you justify your centralized, expensive front for weapons manufacturing? Fusion is coming along now too, and graphene emits electrons when shot with photons, and this produces thrust. Graphene is light and strong enough to scale up to any size you want, and if you have a giant spacecraft you also have the area to install the solar systems to power it.

No.

Why so? Doesn't knowing science mean you can bring progress to the humanity? Solve energy problems? Develop medications?

The typed lambda calculus with [math]\to, \times, +[/math] and bottom type is the proof theory of intuitionistic logic, and the Church encoding is a model for the Nats (like the Von Neumann naturals)
All those terms have their own Wikipedia article.

traditionally, through the curry howard correspondence.

I think the more intuitive one is the curry howard lambek taken not just over CCCs, but rather over topoi (at least I usually imagine semantics are possible because there is a "truth object" - some "table" of truth values G such that maps A->G correspond to subobjects of A).

I believe that adding this puts a few more restrictions on the logic and calculus (martin lof?) But I really don't care that much because I never run into expressiveness issues.

But yeah, basically, curry howard lambek says exponentiating in a cartesian closed category is lambda abstraction is a function symbol etc.

>>7719922
after googling, I'm wrong. The jump to the traditional topos semantics is non trivial. However, the CHL and exponentiation example are true.

row 2 and 3 are flipped then row 2' is multiplied by δ and row 3' by γ so det = 1 => det = -δγ

>>7719569
What happens to the determinant if you multiply a row by a constant?

>>7719569
>if the determinant of a matrix equals 1, that matrix has to be necessarily the identity matrix?

det(
[cos(ϕ) sin(ϕ) ]
[-sin(ϕ) cos(ϕ)]
)=1 for all ϕ
