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 operating. The American way of doing things, as the article briefly mentions, is very different. I'm not saying it is better or worse, just different. This is a cultural thing that doesn't magically change overnight. I know I still get annoyed at how different things are sometimes compared with back in North America, but that is the way things operate here and you have to learn to play the game otherwise you will lose.

The credit card thing is also true too. Cash is king here and I routinely see people with hundreds of Euros of cash like it is nothing. I always see people paying for groceries with 100 Euro notes. Furthermore, I know Germans are much more concerned with personal security and privacy that there is also going to be a push back about having to share personal information with an American company.

Also I live in Frankfurt, and, to be honest, I have no idea why people even use taxis. To get from the Hauptbahnhof to practically anywhere in the city is only a < 20 minute U-Bahn ride. Also, the public transportation in Europe tends to be insanely good and efficient so a ride-sharing app will also have to compete with this as well.

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 exercise correctly with no weight than incorrectly with a lot.

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 of weight and it is ineffective and can be dangerous. Form is way more important than weight. Remember, many exercises are designed with a specific muscle to target and if you don't do it properly, you won't get any of the benefits.

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 exercise despite the huge potential benefits to their productivity and life. So this makes me wonder: what is it about exercise that turns people off? Is it a communication issue? Is it the lack of confidence? Lack of knowledge? It seems that there are constant pushes in the media to be more healthy and exercise but it never seems to stick.

> The end state is fairly obvious - every light, every doorknob will be connected to the internet.

Why does my doorknob need to be connected to the internet? Does my fork need to be connected to the internet as well? How about my shelf? Or my towel?

And if they are connected to the internet, who is collecting that data? Is it secure? What will it be used for?

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 mathematical exercise that likely has nothing to do with reality.

I hate when theorists take some abstract crazy idea and then say the universe has 10 or 11 dimensions when they have no basis for saying that.

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 work exclusively in theory.

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 it ends up with is nonsensical garbage that does little to advance physics.

But yet, there isn't a crisis in physics at all since these theorists are so far removed from reality, I don't really care what they think. They don't really tell use anything useful or interesting so I tend to ignore them. Instead, I focus on things we do know exist but cannot explain, say astrophysical jets, pulsars, or supernovas. We know they exist and we can see them, yet we understand them very little. We have models that are getting better and better over time, but they all exist within the current understanding of physics. This is where physics really is. Whatever garbage the theorists put up on the arxiv can be ignored with little loss.

Instead, those of us "in the trenches" can continue our work trying to explain observed phenomena with our current theories. There is no need to add in extra dimensions or cohomology. Maybe, when we've done really understanding our current theories can we talk to those theorists again.

Incidentally, since I started my PhD in physics doing numerical relativity, my views on science have changed completely. I used to be interested in stuff like string theory, but actually sitting down and trying to do it left me feeling empty inside. Now that I work in an area that is very closely related to observations, I feel like I am actually learning something about the universe. It's hard to explain philosophically, but I really believe in experiments as the guiding principle of science. In my case, we see pulsars (2500+ of them) and we have yet to provide a full explanation of their nature. To me there is something more real and scientific about this then trying to explain multiverse theory but I don't know the words to describe it.

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 one book I like called Quantum Processes Systems, and Information by Schumacher (who coined the term qubit) and Westmoreland since it is an introductory text and has a good discussion of the basics of quantum computing. It does, however, assume you are a physics student with a good understanding of linear algebra.

>There needs to be more people chasing their dreams rather then being cranked through the academia process.

I am reminded of the following story I experienced in my first year chemistry class. The class was being taught by the head of undergraduate studies for science and he asked us (a room of 500 students) how many people wanted to become chemists and maybe 20 or so people put up their hand. How many people want to become physicists? Maybe 30 or so put up their hand. How many people want to become doctors? A good 400 people put up their hand. He then said "only 20 of you will make it to med school, I hope you have a back-up plan."

The problem is that we only hear about the success stories not the vast amount of people who fail. That isn't to say don't follow your dreams, but be realistic about them and have other options available when things don't go your way.

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 that? I'd be curious to know if he has done anything illegal.

Additionally, I wonder if he is doing this on person to make a point about drug pricing in the USA.

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 plate on the bar. Not a very visual thing.

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 to programming puzzles, where the solution is often some clever trick that, once known, makes a problem easy.

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 programming language you want, as long as you have an FFT routine.
