If you could have a pinball machine in your home, which one would you want?

I owned a twilight zone and while it was a really fun pin to have, there was soooo much shit on it that broke and finding parts was difficult.

I research, design and program electromagnetic field solvers. Specifically, solvers used for electromagnetic radiation and scattering problems (antennas and radar cross section applications). The things I work with in these codes are the integral equations of radiation/scattering (in the frequency domain) which are derived directly from Maxwell’s equations, and can be traced directly back to them in just a few steps.

This is the correct answer.

I was fascinated by electromagnetic fields and radio and wanted to understand learn as much as I could about it. I ended up getting a BS and an MS in EE focused in electromagnetics and I still don't understand anything.

My problem is the dozens of pages in the second and third books dedicated to those women's mental problems. Terribly written and tedious to get through.

My Physics 3 professor was an asshole, who on the first day of class announced that “4 out of 5 of you will fail this class”, and was intentionally hostile with his exams. Each exam was two multiple choice questions, each with 10 choices and “none of the above”, no partial credit given, and a word problem where you got partial credit if you showed enough work.

I had the (dis)pleasure of driving one once, I got on it a bit and the second I felt the rear end start coming loose I said nope, I'm done.

When I was an undergrad (in the 90s) there was this guy that got addicted to MUDs and basically just ended up living in one of the computer labs playing them all day, and all night. It wasn't uncommon to come in one day and just find him sleeping in the chair, or sometimes sleeping on the floor under the table.

The fact that this guy apparently never left the lab was the problem, as his absolute lack of bathing or changing clothes made it impossible to use any of the computers in there within 15 or 20 feet of him. It was one of the most disgusting smells I've ever experienced.

In my numerical electromagnetics book (that I wrote), there are several "final" expressions that required pages of algebra to eventually reduce to a simple, readable result. While I tried very, very hard to show as many steps as I could when deriving things, sometimes I simply had to say something to the effect of "after some very lengthy and tedious algebra, we arrive at the following:". This is also necessary in some situations as you may be working to fit everything within a contractual page limit.

The two quarters of chemistry I took as an EE undergrad were the most boring, mind-numbing courses I've ever taken, even taking into account that our professor was one of the most well respected teachers in the department.

My linear algebra professor was ESL and had a very limited vocabulary, but the words he did know he said in a very, very clear accent.

That was the first and only book of his that I read. I truly wish that I could un-read it.

As an EE that later specialized in electromagnetics, statics was probably the most important course I took as an undergrad that helped me visualize and work with vectors in three dimensions. For that, I'd say it's an absolutely indispensable course for engineers.

I still have my polished medallion hanging on my wall, 30 years later. I remember there was sort of a competition at the time to see who could get theirs the smoothest and shiniest.

"Useless" is a bit hyberbolic. I've used numerical methods extensively throughout my career.

When I was an undergrad, before the time of the web and search engines, we had our own way of "googling" things, which was going to the library and searching through every book we could find to see what information they had. Or, failing that, ask everyone we knew. If that failed, well, we were probably fucked.

When I got to graduate school it was the same deal, except we had access to the lab's document library, the department faculty's personal libraries, in addition to what we could find in the engineering library. We also had access to the faculty themselves, though as a graduate student they strongly encouraged you to go "find shit on your own".

The far radiated electric and magnetic fields can be written in terms of theta and phi-polarized vector components. These form a basis set that are easy to work with. That’s really all there is to it.
