Also, beyond general appreciation of science, I don't know how much application modern physics has in daily life. I'm an actual practicing physical chemist and I barely ever have to consider relativity (it does occasionally come up) much less stuff like the strong force.
I agree with you here, especially the first sentence.
Re: relativity -- relativity is generally something that doesn't need to be considered directly yet modern physics is impossible without it. That is, sure, you don't have to directly consider relativity but it's rather impossible to perform the vast majority of anything in the sciences and its applications without it. It's more or less 'encoded' into everything and just taken for granted (not a reply to you Gibonius, but more of a general exposition for those who otherwise would misconstrue your statement).
Re: the video. Yeah, pretty dumb. The problem with learning anything from the 20th century is that the mathematics are far more advanced than possible for the average high school student. It's pretty useless to talk about even basic concepts in relativity like the Lorentz transformation when the students don't have the necessary mathematical knowledge to understand it in any meaningful sense.
Besides, there's enough to be learned before the 20th century. Heck, it's hard at this point to find a general university-level physics book with more than the near-useless integral forms of Maxwell's equations (I assume the video maker chose 1865 to make the comment about slavery and because Maxwell's equations which govern nearly all of electromagnetism were formally published that decade). So yeah, until vector calculus becomes part of the standard mathematics curriculum in high schools it's probably best to stick with f=ma.
(Really calculus should be taught alongside Newtonian physics, but even that's a tall order).
