I second this. No joke. Everytime something happens there are 5 million threads about it in the following months and not only do I get to hear the story, but also I get direct knowledge of the opinion of students, scientists, racists, sexists, trump voters, hillary voters, black people, white people pretending to be black, black people pretending to be white, europeans, americans, americans pretending to be europeans and europeans pretending to be americans.

This is probably the best news source.

Hey guys.

I'm trying to prove that u.v=|u||v|cos(theta) without using the law of cosines.

But rather by showing it with the law of cosines I want to use a triangle like this:

hypotenuse v, base proj v onto u, final side v - proj v onto u.

I feel really close in doing this but like I'm missing something.

I have (u.v)/(|u||v|)=cos(theta)
then
(u.v)/(|u||v|) = (proj v onto u)/v

but can't get the next step. writing out (proj v onto u) as the definition of orthogonal projections (with the dot products) doesn't help me.

Has anyone done this before? It can be done, right?

I wish I took this shit in uni

>>8596951
You have it backwards.

[math]cos (\theta) = adj/hyp [\math]

implies u.v is adj. And ||u|| ||v|| is the hypotenuse
>>
>>8596991

so you're telling me that

u.v = proj (v) onto (u)

and

||u|| ||v|| = v ?? that can't be right.

i have a right triangle drawn - imagine u on the x axis and v at (1,1).

Hello you wise /sci/. Is it worth for an aerospace engineer to do a MSc in Air Traffic Management or Airport Planning? Can you even consider them engineering fields anyways?

I was just wondering if they can be a good studies for anyone to take (in terms of salary and work conditions). Obviously they seem appealing in terms of being interesting, but it seems much responsibility for an unknown but probably standard salary.

Powerful men. Some achieved this through being physical freaks, others through cunning and prowess (which would correlate with intelligence).

Sup /sci/ I'm a 3rd year chem student and looking into getting a phd because a bs alone doesn't pay shit.
Here the problem: I can't decide on what to specialize in, and as the masochistic retard that I am, I'm contemplating doing two simultaneous phds. So here's the question: if I do that, do I have to do two doctoral thesis or can I make one thesis that encompasses both areas? Because I don't mind taking extra clases but two investigations is sort of overkill.

Yo,

so im starting uni next year and i wanted to do comp sci, however when i look at my unis course it actually seems pretty shit, theres no architecture units at all and i really cant tell what its even focused on, it looks like a bunch of random subjects to me

http://handbooks.uwa.edu.au/majors/majordetails?vdir=mjdcmpsc

the level 1,2 and 3 units barely rely on the ones before it.

So i looked at the engineering degrees and the electrical engineering degree barely touches on that sort of stuff in the third year.

http://handbooks.uwa.edu.au/majors/majordetails?vdir=mjdengsc

idk what i should do, i have a partial scholarship / grant whatever but its too late to apply to other unis.

I agree. This barely scratches the surface of a real computer science program.

>i really cant tell what its even focused on, it looks like a bunch of random subjects to me
That's not necessarily a bad thing; computer science doesn't really have a deep focus that everything builds towards. But it is true that this program is far too shallow to reach anything interesting.

>So i looked at the engineering degrees and the electrical engineering degree barely touches on that sort of stuff in the third year.
Yeah; electrical engineering is not in fact computer science.

>idk what i should do, i have a partial scholarship / grant whatever but its too late to apply to other unis.
Find some way to get your ass to a university that actually teaches the subject you're interested in, I suppose.
>>
>>8596567
Not random at all. The requirements are essentially the basic requirements of all CS majors. The only difference I see is only 1 mandatory programming course (normally there are 2-3) and no architecture.

OS, Networking, Compilers, Automata, Programming Languages, etc tend to be electives. You have to build a core before you can take specialized classes.

im looking at curtins program http://handbook.curtin.edu.au/courses/32/320911.html and it seems way better. their double major also looks interesting but its a 5 year degree

http://handbook.curtin.edu.au/courses/31/319545.html

or

http://handbook.curtin.edu.au/courses/31/319544.html

im not sure which one to go after though, ill probs see if i can apply for the july intake or something

the electives dont really cover any of this though, at best theres python as an elective

The proof that [math]e[/math] is a transcendental number is super easy compared to the proof that [math]\pi[/math] is a transcendental number. In fact, just look at this proof: http://www.cs.toronto.edu/~yuvalf/Herstein%20Beweis%20der%20Transzendenz%20der%20Zahl%20e.pdf

You then use the property that if [math]e^x+1=0,[/math] then [math]x[/math] must be transcendental. Now, [math]e^{i\pi}+1 = 0 \Leftrightarrow i\pi \text{ is a transcendental number } \Leftrightarrow \pi \text{ is a transcendental number, because } i \text{ is an algebraic number.}[/math]
