Nice introduction. My colleague works exclusively in raytracing around black holes (although he uses the Kerr metric) and he has produced some really cool images. I highly recommend looking at the literature for really cool images with more

True. I'm just a lazy relativist though ;)

Since these are Euclidean spaces, the difference between contravariant and covariant indices is non-existent. So it doesn't matter whether the indices are upstairs or downstairs.

I've attended Palantir tech talks before and they try to "hide it". Everyone in the room knew and the person giving the talk kept talking about the other uses of Palantir beyond government things. However all the examples the

I think the greater problem is not with the standards (which I know nothing about) but with who is teaching it. I have talked to people who are elementary school teachers who know nothing about mathematics, yet they are given the task to te

I was very lucky, from an early age, to be told that I should focus on learning how I learnt. I figured out how I learnt best in high school and never looked back. Now I have no problems learning any skill becase I know how my brain learns

Why is it the government's job to tell companies they cannot be monopolies, especially in non-essential services?

No one is forcing you to use Google, Facebook, Amazon or any other Internet website. End of story for me.

I don't believe it was borrowed as it is something that is definitely taught in courses. I remember learning it at some point early on in my mathematics education. I definitely know I knew it by my vector calculus course (2nd year) whe

And that's why they have 8 month co-ops in addition to 4 month co-ops.

I don't think it's that uncommon. The advanced GR course I took used tetrads and spinors. It seems to me that this is rather standard for a graduate GR course.

I agree and disagree with what you're saying. I agree it is laziness and bad science that physicists stopped caring about the philosophical underpinnings of quantum mechanics but I disagree that it was because quantum mechanics not bei

What does this mean? I've seen this before and I don't get what it means. Look more like the actual equations? Can you give me a concrete example of Haskell code that solves a simple PDE?

Not really. Intro calculus hasn't changed much in the last 100 years beyond becoming more and more streamlined. Although in a newer book you might see more modern applications and maybe some more streamlined proofs.

Most introductory discrete mathematics textbooks should cover basic graph theory.

Sorry if I am sceptical but I don't really believe your claim that you were able to obtain a sound working knowledge of calculus from the Principia. For one thing, Newton barely makes use of calculus in the textbook and instead opts fo

Analysis of Over 2,000 Computer Science Professors at Top US Universities I was expecting universities from all around the world but this is just the US.

Another interesting point is looking at the time of graduation. There is a big difference between a high school diploma in the 1960s vs the 2000s thus making it an unfair comparison. Back then it was much easier to go places without a diplo

Zuckerberg, Gates, Gaga, and Dell all had upper class parents and attended exclusive private high schools. Jobs was brilliantly smart but did come from a lower class family. Oprah comes from a very poor background and did make it successful

I agree completely. I am very fortunate to have been taught a young age on the importance of learning how to learn and is something I was able to work out in my early teens when life is a lot simpler. I absolutely ate up university because

I guess, but at an HPC conference I went to last year there was a big session on Hadoop and introducing it to the researchers as a potential alternative for certain tasks. I also believe that technologies take a lot longer to penetrate acad

Apparently people didn't like what I said. But I stand by it. If you are using the built-in random number generator in your simulations you are doing something VERY stupid. The built-in random() is not a good source of random numbers f

If you are a computational scientist who is using random() for any part of your simulation, you are an idiot.

Absolutely! Has anyone written a server in Fortran?

by cabinpark 12y ago
I think people forget that Fortran was designed to only do mathematics. I don't know of any other languages that are designed just to do number crunching and nothing else. Even though C is very low level, you can write almost anything

I was going to write a long post but you really summarised my thoughts exactly. Haskell and Clojure don't even make my list of scientific programming languages. My old university switched from C++ to Python for teaching the physicists,

That's a poor reflection on his education then. Even the purest mathematics majors I knew still were aware of the applications of most of what they learnt.

What are multivariate differential equations? Is that another name for partial differential equations? If so, then I assume your office mate was joking?

Unless you misunderstood your professor, what they said is entirely and utterly wrong. Calculus of variations is one of the guiding principles of modern physics. Pull out any textbook on quantum field theory or general relativity and there
