What is the CATRA scale? Searching brings up a fictional character from a cartoon, and something to do with knife sharpening.

The order seems fine to me.

Thermodynamics/statistical mechanics was taught as a junior level class at my undergraduate alma mater. During that year, students would take electrodynamics, classical mechanics, and statistical mechanics as separate classes in some loose order, although of course simpler versions of these topics would have been introduced in first year physics.

The lack of fluid mechanics also, unfortunately, tracks with my experience.

Your experience matches mine, except for the libraries. In my experience at 3 private eastern US universities (two ivy leagues and one liberal arts), all libraries required university IDs or a pass to enter beyond the lobby. I do not know what was required for a non-university person to obtain a pass.

I doubt it. The bullet movement may be chaotic, which means that tiny changes in initial conditions will drastically affect the trajectory, but it is theoretically possible to predict the trajectory. However, it is likely that quantum effects such as the movement of an electron through slits is actually non-deterministic, so we can only predict it in a statistical way even in principle.

This is also my experience with Patreon. Recently, I have been receiving popups from them about opting out of marketing emails. However, they do not seem to save my choices and ask me this every several days.

His books are everywhere in airport bookstores in Canada and the US. I think I have also seen them in large bookstores, such as Indigo.

A few months ago, the Canadian government chose to prioritize first doses first. I know the BC government changed their vaccination schedule after this announcement such that everyone should be able to get their first dose by June or July. https://news.ycombinator.com/item?id=26360556

I believe this was addressed in the first few paragraphs of the article: this problem is not about 'information', which is a vague phrase. Rather, it is about how black hole evaporation is fundamentally time irreversible.

But every side faces the sun at some point. The first paragraph of that article even says so.

I have the opposite experience on this site. I am not a software engineer, so every time I see the word "go" in a submission title, my first thought is of the game.

Are you referring only to the title?

Any undergraduate level textbook on E&M. Griffith's 'Introduction to Electrodynamics' is a commonly used one.

>Take a look at Primark seams and then take a look at Brooks Brothers seams

I'm not familiar with either. Which store is supposed to have the better seams?

According to his Wikipedia article, he held a professor position without a PhD. Is that usual in parts of Europe? That seems unthinkable in the US.

I suppose this is as an appropriate time as any to ask for advice: I am a multimillionaire from inheritance, and am about to complete my masters in physics. I wish to work on long term theoretical physics problems that do not seem to be possible under the current publish-or-perish academic system. The plan was to complete a PhD, then leave academia, but lately I have been having severe doubts about continuing onto a PhD, partly due to the cruft that comes with academia. Obviously, future employability due to financial reasons is completely irrelevant to me.

I would greatly appreciate any advice.

I've been reading this site since 2009 and can barely write anything more complex than Hello World. The guidelines on submissions say nothing about software engineering, and the definition of hackers as written by Paul Graham does not limit it to software engineers.

I will definitely bring this to the attention of my PI.

The process is blind, but it's fairly easy to know who the author is just due to the topic at hand. At least for specific subfields.

In British Columbia, the speed limit is defined as the maximum speed limit when the road is bare and dry and visibility is good. From the driver's guidebook[1]: >Aim for a speed that’s appropriate for the conditions in which you are driving. The posted speed is the maximum for ideal conditions only. Choose a slower speed if the conditions are not ideal — for instance, if the roads are slippery or visibility is limited.

If a driver was driving too fast to react and stop without hitting that deer, then that driver was driving too quickly.
