nothing says "I can't think for myself" more than that last thing you said.

You don't deserve a degree if your only competence is to rewrite what's in a fucking book.

No.

No. Please, post the list, OP.

No.

Note to people attempting them: don't get discouraged, they're not particularily easy.

How is gcd defined for real numbers?

>>8081466
Not for real numbers.
the entry of i-th row and the j-th column of the matrix is gcd(i,j).

>>8081311
Define "smart"

>>8081311

Tesla.

>>8081314
Yes, Perelman might be better at pure mathematics but Einstein might be more creative.

>>8081064
I imagine it like a 2D space with 3 dimensions condensed into 1.

>>8081064
Math exists by itself, but not outside of itself.
Applied math is just situations that are similar to math.

It helps if you don't think of math in lower dimensions as physically existing in some space.
It's hard to conceptualize below one axis, so picture a line for that.
With two axes, you have a line with varying properties.
With three axes you have a line with varying properties and those properties have varying properties.
With four axes you have a line with varying properties and those properties have varying properties which have varying properties.
With five axes you have a line with varying properties and those properties have varying properties which have varying properties which have varying properties.
... and so on.

As a function with n dimension, i just think that the Y result depends on n things.
It doesnt have to be a thing visualizable per se.

>>8081032
how many times do you plan to post this shitty rewording of zeno bait here

>>8081038
Maybe I'm ready to prove how Zeno was on to something now?

So why and how do you disagree with what I've stated?

Zeno's paradox is irrelevant to everything, but also bullshit. It's on the level of "what's the sound of one hand clapping?"

Get a life

This is beyond briliant. A drug that literally makes you cum, the amount?of potential junkies this product could bring, the revenue, if only we could?make it so no does in fact ejaculate and incoprate that in the drug. Jesus Christ whoever could make this would be filthy rich.

I think the opposite (a drug that can be taken at will to prevent you from ejaculating) would be more profitable.

Why would a lazy person go for a fucking PhD?

What the actual fuck. Why would you get a PhD if you are not the most dedicated person in your field in the entire universe.

Faggots like you keep telling universities that they have easy money by simply opening more spots than there should be so retards like you come in there, barely hang on for 2 - 3 years while having payments up the ass, and then leaving with no degree at all.

Just go get a job and go on with your life, you are clearly not even the type of person who should go to a university.

I can tell you right now, 50 years ago, you wouldn't have gone to a university. You'd be going to a tech school and smoking crack. AND YOU'D BE HAPPIER THAT WAY.

But you had to swallow the "university prestige" meme that simply says that instead of paying 500 dollars to get your electrician degree, you pay 50000 dollars to get your trans dance folklore studies degree.

Good job.

Other general stupid things I've done: pointlessly took 40 credits more than whay was required for my degree. Also, my semester grades are all over the place. I once literally had multiple (2) A+es and (3) As in the same semester as I had two Bs. My transcript literally makes me look like a genuine autist.

>>8080991

I'm lazy about doing class work. Certain class environments make me not lazy. I'm also not lazy when it comes tobmy research. (Research is why I want to go for a PhD.)

Also, I didn't pay anything for my education.

>>8080839
It just gets passed around that subject's qual committee members here.

If you make it to the point where you're hired as a professor of math at a uni ID assume you'd be able to teach pretty much anything.

>>8080839
Every faculty member and graduate student is qualified to teach those courses. Ideally the instructor in topology is a 1. a professor and 2. topologist so he or she can answer more advanced questions from curious students.

>>8080736

I don't think anyone cares what school you went to, or who's dick you sucked.

If you can do the job you're told to do, then that's all there ever needs to be.

Should've stuck with economics bro.

>>8080736

Dammit OP. Do you realize how hyper-competitive physics is?

Any discovery that you make would've been made by someone else 10 minutes later.

For fuck's sake, if you're actually not a retard, work on something that actually matters, like nanotech or biotech or 3d printing or AI.

The last thing this world needs is more fucking physics majors.

>>8080756
b-b-but the memes told me to do physics

I am interested in condensed matter physics and its industrial applications, and computer security.

I'm not doing it for the pop sci physics like cosmology and particle physics.

>>8080647
>scientific disciplines
>astronomy
I hope you meant astrophysics, pleb. Astronomy is better than astrology, but only slightly better than photography in terms of actual science.
>Astrophysics master race here

>>8080667
Isn't astronomy pretty much experimental astrophysics? Like astronomers observe shit, astrophysicists explain said shit.

>>8080671
No. "Experimental astrophysics" is experimental astrophysics. Explaining the shit that experimental astrophysics observes is theoretical astrophysics. Astronomy is just a hobby.

With survivors?

>>8080537
WITH NO SURVIVORS

>>8080528
this was a real stunt, so yeah

>>8080526

did you consider that maybe you are autistic and nobody else feels like this

>>8080526

>why are homo-sapiens attracted to water and vegetation

>>8080526
These colors are false colors. You knew it.

no one ask why, just ignore the thread.

>>8080891
why?

Computerphile has gone to shit lately too, case in point:

>internet censorship is... censorship of the internet

I made a comment about how shallow the video was... and they censored it.

>>8080466
if it is modelled in 3d and you have roll/pitch/yaw you just set 2 of those to 0 and one to 90

What happens if you just pick the edges of the first image and apply the same transformation?

>>8080488

OP here:

I need to do this for multiple images, which all have different roll/pitch/yaw.

I want to create a birds eye view, so I don't know if what you're suggesting would help
