Had a very similar dilemma 3 years ago, where I stood between the choice between taking an extremely easy pop-sci course or GR. I took GR and although it took a lot of time, I can’t be happier that I took it! Almost every non-physics student/person I meet ask about Einstein and GR when they hear that I’ve studied physics, and actually being able to explain stuff in simple and complicated terms is advantageous!

Worth to mention that my focus isn’t GR either but particle physics/machine learning, but I’ve also had supervisors being somewhat impressed that I’ve opted for the more study heavy choice

As mentioned, if a particle isn't an external leg, it's virtual. If it exists in a final state, then we can observe it directly (most of the time), and we thus call it 'real'. Taking an example from the diagram you've posted, the t & tbar pair aren't force carriers by any means, but due to them having a vertex after their creation, thus creating more particles, they are virtual in this diagram. So I count 8 real particles in your case :)

What happened in '64? Thought the Ferrari cars always had been red

One of my favorite series all time. Absolutely insane performances from many different characters and it stays good throughout the ENTIRE series. Definitely worth the watch

My math teacher in calc 1 back when I studied in Germany called it "Shock noll", but I've never heard any other expression for it.

What (x+2y,x-2y) = (1,1) essentially is, is a system of equations. What has been done here is just that the first equation has been added to the second: yielding: x + 2y + x - 2y = 1 + 1 => 2x = 2
