You can extend the dot product to imaginary fields, there are a couple of standard extractions. If I remember correctly (but my quantum physics background is really poor, so I’m ready to be proven wrong) the one compatible with the bra-ket notation is
a dot b := sum_i conj(a)_i b_i

I don’t. It’s the sort of thing that is “evident” so no one talks about it much. Plus, professors don’t want to point out how much the whole system sucks

Where does this definition come from?
All the geometric definitions of tensors I have met always assumed a base, such that a change of coordinate or of parametrization would change the values of the tensor. Unless you define the tensor by its action instead of its values?

- Comment on better paying job dealing with egos vs peace of mind job that pays poorly. I'd be taking a 20% financial hit. Worth it? 4 days ago:
To build up on it: think long term as well.
Nowadays, it’s a 20% pay reduction. How does it look for long term? Will you have growth options in the new position? Will it sabotage your resume? Will you be able to keep adding to your 401k? How likely it is that a rotten apple coming would spoil the mood in the new job?
And: are you really really absolutely sure that the new job would be more chill for you? Think about yourself and think about how you would feel in that job after 6 months to a year. Would you still appreciate it? Would you get resentful because you have little to do while you could do so much more? What would be your frame of mind after a while?

- Comment on Anon tries to meet girls at college 4 days ago:
Honestly, I have seen many classrooms in which no one was talking to anyone. There would be a break in the lecture, and the lecture hall would be absolutely silent for 10-15 minutes until the lecture resumed. Other classes were a bit more chattery, or even way more. As a teacher now, it seems anecdotally that the problem is getting worse, but that’s what every teacher always said (“these younger generations!! Mumble mumble”)

Me too! That wasn’t even the inly time I got comments on my code. Since then, I make a point of doing at least a cursory check on codes when I review as well

Yes. Yes, everything works a-okay. Somehow I fixed the code but never removed the obnoxious, full cap comment…

- Comment on Wife has COVID and I've had a lung infection for almost 2-weeks. Should I worry? (background in post, mods read the first bit!) 6 days ago:
As a general statement: worrying doesn’t help, only raises your stress levels and negatively impact your immune system.
There are here causes for concern, and your fear is justified. Other than isolation from your wife, there is not much to do.
As a side note: being in constant contact with other humans raises your immune responses, because you are constantly trained to fight off mild infections. Coming back from full isolation was really rough on my partner, they kept getting “the flu” (something or other) every time they went to a crowded place, even just the supermarket at rush hour. It took them a year to develop a normal immune response again.
- Comment on Wife has COVID and I've had a lung infection for almost 2-weeks. Should I worry? (background in post, mods read the first bit!) 6 days ago:
As long as you don’t have symptoms, assume you are healthy, and stray separated. Obviously, if you already got Covid yesterday, then that ship has sailed, but what if you didn’t? What if your immune system is still fighting it off and will give out in two hours? Chances are slim, but not none.

About your brain chemicals rewriting reality: I remember giving birth as totally chill time, nothing difficult, all smooth. While I also know for a fact I was crying that I couldn’t make it and my kid ended up overnight at the NICU. Somehow, your brain still tells you “all is great”
- Comment on If your happiness is derived from your enjoyment of a false (i.e. fictional) stories, is that truely happiness, or is that technically a delusion? 1 week ago:
Good point!
Other hypotheses: we say “true happiness” when it’s sustainable (for a bit) without obvious negative effects. Thus drugs are stereotypically not sustainable and with negative effects, so they are not true happiness [obviously many would disagree, e.g. Baudelaire] and finding true love is true happiness. Thus, stories are also true happiness.

I think the concept of “false happiness” is given by the ends result of such behavior. Doing fruits gives you a high, but also addiction, so in the long run it’s bad for you. Having a fake relationship does not allow you to develop a real one, thus being a negative over time. True happiness is something that should make you happy in the moment and in the long run.
For this reason, media is true happiness.
I wad happy reading the lord of the rings and I’m happy I read it. The happiness reading produced has kept being a source of additional happiness. I remember Bilbo’s songs, and think about them when I take a walk. I remember small little details, or big plot points, and I’m happy to remember them. Same can be said about films and video games (I am just less passionate about them, but that’s just me)

I agree on the first part, I am unsure about the meaning of the second one. Reading a book is for me a great source of happiness, and I wouldn’t completely replace it even given infinite resources.

Personal must try in Munich that hasn’t popped up yet: the Residenzmuseum. In general, the whole city center is incredibly pretty, but the museum of the palace of the “kings” (not always really king, I mostly forgot the story but the local area boss) is positively stunning. Each new big boss built a new section of the palace, making a very complex architecture with the specific intent on impressing the visitors. Even hundreds of years later, it still does its job.
Neuschwanstein is the Disney castle. Equally fake, equally magnificent.
If you go in September, you have to pass by the Oktoberfest. It’s a huuuuuge town fair, mostly centered around beer, rowdiness and chanting, but if you go before “drinking time” (aka 4ish pm) it’s quite family oriented, with plenty of food stalls and general fair flair.
Tollwood has already been pointed out, there is the summer version and the winter one. It’s a “hippy” festival centered around discovering world cultures. Lots of music, from local artists to world known (for which you need to buy tickets in advance).
If you go not in winter, you have to try out a beergarten, traditional places with beers and a limited selection of local pub foods. If you go in winter, the Christmas markets are fun, even if the Munich one is not particularly well known.
Have a good walk by the Englisher Garten, a massive park in the city center. Avoid eating at the Chinesiche Turm, that’s too much of a tourist trap.
As others have pointed out, you are in the middle of Europe, so you can easily consider small trips all around: Berlin, Paris, Vienna are all a direct train away. Rome, Madrid, Barcelona, London have direct flight connections.

Incredible how much changed in 20 years! Thanks for sharing!
- Comment on Funny how there were no food allergies 2 weeks ago:
Adding to this (not wanting to engage on the main post): allergies have been increasing also because our environment is getting more polluted by the day. Unfortunately, allergies not being known and detected earlier means that good studies on the “real” increase of allergies are really hard to make. Same with mental health issues, that “didn’t exist” some decades ago (people either could bare it or committed suicide, that was incredibly often covered up by the family because it was shameful)
- Comment on Anon saves up 2 weeks ago:
My position is a state position in Europe. Since the specifics of the contract are standardized, and can be found online (theoretically), I didn’t have to sign a contract to start working. I hated it… still do, even if the job is overall good. I only have a piece of paper from HR stating that the state granted me the position.
- Comment on Socially inept, introverted employees. How do you survive the workplace? Because I’m in dire need of some serious advice. 2 weeks ago:
I might come across as abrasive myself in this comment, you are free to completely discard anything I write.
You were fired after only 8 weeks from a position as ER nurse. Aren’t ER nurses quite difficult to find? 8 weeks is a pretty short time. So the managers considered, after such a short time, that it was better to loose you than to keep you. That having you in their team was a negative. And they didn’t warn you, so they thought that either you would not heed the warning or that your behavior was too serious a liability for them that they would skip the warning all together.
Considering this, I would encourage you to find their point of view on the matter. Even if it seems to you that everything was good, did you overlook communication? Did you act as a lone wolf in a team? Did you overlook to show off your own contributions? Each one could have significant ramifications.
The examples you give are quite extreme, did you communicate about them correctly or could you communication look like pointing fingers? Did you follow up on them in the way that is usually used in the team? Did you make an enemy of a key player?
I know work politics can be exhausting. In this direction, I don’t have advice other than learning from every experience.
