I'd like to stress the term "unwittingly"!

Plasma is hard. If you go down that route, we will meet, someday. It's not a terribly large community. :)

Absolutely, it came on its own while I was trying to understand what exactly you were talking about last week here.

    Plasma is hard.

Good! I crave for hard problems. It's definitively not your standard QFT where I could bumble through most of the problems in Radovanovic's problem set purely on my knowledge of operators. Introductory books for plasma stretch my limits, and you can't put the price on that.

    If you go down that route, we will meet, someday.

It would be cool, although with my US visa being declined, anything like that is likely a good few years away from me.

Just saw this, my bad. (Great pun thread over in the new pub, btw, let's keep it going indefinitely)

I think plasma is just a new regime of physics for you to explore. Hopefully you don't tire of it too quickly. :)

Speaking of, I've gotta do a proof today of the convolution theorem for both Fourier and Laplace transforms. It's on wikipedia, though, so what's the point? Also on wikipedia: incredible animations. My favorite is this depiction of Liouville's Theorem. These are popping up in a lot of new places over the last two or three years. Class notes are becoming more and more irrelevant, unless they are used as an attendance grade, i.e. burying requisite information for homework in the middle of a lecture.

I tallied the total number of graphics from my course's content this semester. It's like... 10. Static, 2D plots, all of them, and the count even includes a graphic showing the definition of the coordinate system used to handle large angle scattering. The rest is equations and some words. I'm a spatial intelligence person, that's pretty much why I went into this ruckus, and to have some of that taken away is rough, especially when this is absolutely a physical system, not an abstraction like QM. Still, it helps you grow, but growing hurts. Fast growth, especially.

I've been a little more than slightly alarmist, recently, but I do worry about the state of academia. My plan is to (re)join and cultivate the growing number of "private sector" academics, but I worry my doing so is contributing to a greater problem. The money, first granted to one gov't branch by another, must then exchange hands once more, through contracts between gov't and the private/industry group. Dude, I don't know what it's like in your realm, but every time I turn around, someone high up in an institution has agreed to roll out someone else's kid's software (or whatever reason), and it takes all of the clerical people suspiciously long to learn the new workings. The argument that the bureaucratic structures have ballooned to wholly inefficient entities holds many buckets of water, and we've simultaneously made it more difficult for small business owners to get off the ground, especially small business owners seeking federal $'s. I've digressed, sorry. Pretend that I gracefully made my way back through the rant to establish that without some type of intervention, scientists will be leaving the United States in measurable numbers over the next few years. [edit: since concrete predictions are always preferable, I'm guessing 7% - 9% of scientists will leave the U.S. over the next 5 years. Total number of scientists is ~6 million, so I'm saying about half a million scientists throw in the towel] Trump's not even so much as a kick out the door. Maybe I'm wrong, but I know I've seen some characteristics in several different departments that I wouldn't peg as "healthy". And nowhere's perfect, but we've got several of the worst problems extending across the nation.

Sorry for the doom n' gloom. We'll be OK, bro. Compared to the rest of society, things will just about always look better for us, so it's hard to get bent out of shape. Speaking of, I might postdoc in Stockholm, Austria, or Norway, but I might not postdoc at all. Got options, at least.

Cheers!

I don't know. Even if that would be the case, I like it a lot more than what I have seen in some of the other disciplines. I only definitely know that I don't want to be involved with mathematical physics and that's about it.

    Speaking of, I've gotta do a proof today of the convolution theorem for both Fourier and Laplace transforms. It's on wikipedia, though, so what's the point?

In the words of one of my lecturers "Always practice the basics!". Forgetting about them or deeming problems as 'too trivial' is, in my opinion, a path to complacency. Seeing how my programmes at uni seem to have a student half-life of around 2.5 semesters you bet that I'm going spend some time on freshman problems, just to hone the edge. ;)

Even if it's a boring chore, that's a type of training. And you don't skip the mathematical analysis day.

    The rest is equations and some words. I'm a spatial intelligence person

But aren't these complementary?

    Dude, I don't know what it's like in your realm, but every time I turn around, someone high up in an institution has agreed to roll out someone else's kid's software (or whatever reason), and it takes all of the clerical people suspiciously long to learn the new workings.

I'm not privy to this type of stuff but seeing how administration at maths department has been recently reduced I hope that's the new management purging the excess fat from this delicious bacon. It's not much, but even I could see some of the people literally doing nothing there. No matter the time of day, it seemed to always be the break time.

I guess that you can't really live without administration, but some of it seems like a pure waste of space and money. I got my fucking tax return faster than they processed my request to requisition a laptop and projector for school outreach.

    Pretend that I gracefully made my way back through the rant

Dude, come on. I think that I'm making tangents to tangents every other time we talk. Don't mention it and let us embrace that state of things. :P

    Stockholm, Austria, or Norway

Yey, these are places that I can actually visit. Word of warning about Norway and Sweden: food and housing are quite expensive there, especially in Stockholm. I know that you likely did your own research but I can confirm that one bit. No idea about Österreich.
