It doesn't surprise me in the least. Germany is a country of insane regulations and rules. They absolutely love paperwork - all the Germans apologized to me when I first moved here and set everything up - and have a very strict way of

I cannot emphasize this point enough. If you are new to the gym, please get a personal trainer (or someone who knows wtf they are doing) for a session or two to show you the correct form. It's more important that you are doing the exer

If you've never been to a gym before or done weights, please, please, please get a personal trainer for a session or two to show your the correct form. I see way too many people at the gym who have shit form but "lift" a lot

I was very lucky, growing up, to be the son of a sports medicine doctor because, from birth, healthy eating and exercise and their benefits were grilled into my brain. Unfortunately I see too many people in my job (academia) who don't

I have no qualms with mathematical physics at all. I love mathematical physics to the extent my undergraduate degree is in mathematical physics. But the problem is that they are calling it reality. To my mind, string theory is nothing but a

Sorry it was late but I know what you mean. I meant "theoreticians" in the sense that the article is talking about, i.e. those who work on string theory or loop quantum gravity. Many of my colleagues are nuclear physicists who wor

I think high level theory is wandering aimlessly through a field blindfolded with little guidance or where to look. This is because our current theories are so good, we have no idea where to look. So it begins conjecturing and conjecturing.

What's a thing explainer? But unfortunately since quantum computing is still really only an academic pursuit, you're only going to find technical literature or dumbed down to the point of not being worth it. Saying that, there is

Despite me not liking what he has done, I can't really find any faults with what he has done. If he purchased the drug legally then why can't he charge as much as he want? Can anyone point me to the law that says he can't do

What I love about bouldering is it is very easy to mark progress. You can get higher on the wall or do a move. Very motivating. You can see it. I find that in the gym, progress is measured by moving the rod one weight down or adding another

When I was at Waterloo almost everyone I knew at the climbing gym was some combination of engineering, physics, mathematics, and computer science. This doesn't surprise me since bouldering problems, as discussed here, are puzzles, akin

When you use this method you are implicitly making the function periodic. I can give you any function on some interval (sufficiently well behaved) and you can compute the Fourier series of it. Even though it's only defined on the inter

This is called a spectral method and is widely used in numerical codes. I highly recommend Spectral Methods in MATLAB by Trefethen (who someone mentions above) for a very good tutorial. You can freely ignore the MATLAB part and use whatever

I work in numerical relativity and our group produces many, many gravitational waveforms. I even visited LIGO this past summer. If Lawrence Krauss isn't bullshitting (and I have no reason to doubt he would be) then this is absolutely h

Yeah I know. It's hard to squeeze information out of them. I actively tell them to please, please come to me if they don't understand something and I have office hours for a reason. Yet no one takes advantage. At a certain point,

Interesting. Eigenvalues and eigenvectors are one of the most fundamental applications of linear algebra. In physics, quantum mechanics is a giant eigenvalue-eigenvector problem. One application I really like is in machine learning: the eig

Interesting. I used linear algebra with quantum mechanics where eigenvectors represent quantum state of the Hamiltonian which is how I initially understood them. And as for TAing, have you ever TA'd? You definitely get a feeling but I

I always see linear algebra on HN and many people comment on how they never understood the subject. This makes me ask: what exactly is it that people don't get about linear algebra? What makes it appear to be a difficult subject? As so

I'd love to see new physics! Every physicist I know loves new physics. But if you claim to violate the conversation of momentum, everyone is going to be skeptical and not believe it. We have hundreds of years of experiments and observa

This is actually my PhD research! Yes the current thought is that neutron star mergers are the source of heavy elements (iron and greater) over supernova. Looking at the elements produced by nucleosynthesis from the outflow yields very posi

Bullshit. I live in Germany and am learning German but everyone here speaks English. If you even sound the slightest bit non-German they respond in English. It does vary from city to city but I have experienced this universally and have col

Course-work based masters perhaps, but definitely not thesis-based. My Master's degree was entirely paid for and I actually made money. I wrote a thesis that contained original research and published a paper with my supervisor on the r

Good stuff! I love Fibonacci algorithms and if you dig deeper, there are even faster algorithms that exploit even more identities like the fast doubling and look-up tables. It's a fun recreational mathematics thing, but unfortunately I

I am doing a PhD here in Germany and I absolutely love it. It's completely free (except for the 300 euro fee per semester, but that includes the UBahn ticket which is like 200 of the 300 fee and is worth it) and I actually get paid rea

In all my time working in scientific computing and talking with others, I only know of one case. The huge amount of libraries for Python, C, C++, and Fortran make them the obvious choice. Plus functional programming paradigms aren't al
