That doesn't answer the question. When I hear the term data scientist, I assume that the person has extensive training and background in statistics and mathematical modeling. I work with large data sets all the time as a scientist and

While I can understand that for basic stuff, there is no way I would ever attend an online course on some advanced undergraduate topics in physics or mathematics online. There is a benefit of being in a classroom environment when learning a

Linear algebra is insanely important. I would consider the most important area of numerical mathematics to know. Any sort of mathematical modeling you do is going to involve linear algebra at some point. I have argued that almost all numeri

And yet in every scientific paper I have read they still spell out the abbreviations the first time. And these are written by experts in the field. Why? Because it removes ambiguity and makes it completely clear what you are talking about.

I've always interpreted Linus's law in the following way: given a bug, there will exist someone to whom the bug is obvious and will immediately spot it. However the law doesn't state how many people you would need to check, i

I would argue that almost every single linear algebra routine can be interpreted in some form as a matrix-matrix or matrix-vector multiplication. Considering that matrix-matrix and matrix-vector are fundamental numerical operations (they ar

So? Why does it have to be computer parseable and checkable? I've never heard anyone complain about that before. As for your other comment, DerpDerpDerp provides a good answer.

> I think if the purpose is merely to transmit proofs and axioms unambiguously, I think we can have a language that performs just that and nothing else We do. It's called mathematical notation.

A big secret in mathematics is that many ideas in mathematics are rather simple and straight forward. Formulating and proving these ideas in a rigorous and logical manner, however, is the difficult part.

Wow that's the worst. I would NEVER pay for a PhD out of my own pocket. I mean, yes the PhD isn't "free" in the sense of I don't pay tuition. I do but it's included in my funding. I asked a former university st

I have never heard of a PhD student who isn't getting paid to do research. Even at the Master's level, most students were getting paid, with the exception of the coursework people. Are there people who are actually paying for thei

Never assume something is common knowledge! I've seen many links to mathematics things here on HN that I would consider "common knowledge" yet many people were unaware of them.

Haha, completely true. Still it's not as explicit as it could be. Am I being nitpicky? Sure, but the word "graphical" only appears in the context of the IJulia notebook. Again if you want to really sell this to scientist, rea

I'll admit that is an interesting feature honestly the first thing on the list? It's certainly a cool and interesting idea, but I'll admit it's not a super important feature in my view. Thinking back on all the research

I keep seeing Julia promoted as the grand new language but honestly, I am incredibly sceptical. Working in the scientific programming community, I am keenly aware at how slow things move. In only the last few years have I seen a push toward
