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...

Okay so ejaculation is caused by AFAIK release of epinephrine/norepinephrine release, causing contraction of the smooth muscles in some part of your genitals.
Would it be possible to design a drug, that through alpha 1 reuptake inhibition (NERI) or maybe agonism, would cause immediate ejaculation upon administration (I think IV would be the most pharmacocinetically interesting RoA) ? It could have some medical (for exemple in sperm banks) and recreational uses, but I'm interested whether or not it could be weaponized as a non-lethal incapacitating agent, released just...

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.

Finished undergrad today. I was generally lazy and not very meticulous about my studies; as a result, I was only able to graduate with a 3.85 and cum laude (despite my last semester pushing my GPA over magna cum laude). I am doing a research-oriented MS before applying dor a PhD to redeem myself. How retarded am I?

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.

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'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.

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.

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.

Hey /sci/

I am going to be a freshman next year at a top 10 school in the USA, hoping to major physics.

Physics majors have Intro Series I, which can be completed in 3 semesters, and I will probably be able to get an A in it.

Then there is Intro Series II, which is very accelerated, takes two semesters, and is often described as the most difficult course on campus by both students and advisers. I would probably end up with a B in this course; it is very difficult to get an A.

Should I go for Intro Series I or Intro Series II? Does difficulty of your...

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.

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.

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.

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

How can you transform any image from the left one to the right?

I want to do this WITHOUT choosing 4 reference points, but i DO have access to metadata like roll, pitch and yaw

>>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?

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