Historically this stuff was covered in Dynamics at the sophomore or junior level, though these days a lot of it has been moved to an “advanced mechanics” class at the senior level in a lot of programs. And that’s unfortunate for exactly the reasons you mention, since students are often being exposed to QM before or at best concurrently with that material. Hell, some programs treat it as a damn elective, which is complete madness.

Graduate programs get into it, of course, and my classical mechanics course at the graduate level was one of my favorites because once you start to get a handle on this stuff it’s actually really cool. I should actually take a look through the resources you posted, it’s been a long time since I engaged with it since I don’t teach those particular classes.

Anyway, for what it’s worth basically no one has a grasp of QM that I’d call “intuitive.” ;) It’s just too outside the scale and framework our brains evolved to deal with.

I’m not exactly sure why calculus physics isn’t taught this way in introductory courses. It’s not terribly difficult, and you can easily derive Newton’s laws from Lagrangian mechanics and vice versa. (In fact, it’s way easier to derive Newton’s laws in rotating reference frames–or really any coordinate transformation–using Lagrangian mechanics.) It would be helpful to have some context for what energy is and why it’s conserved (actually, almost by definition, it’s just “what is conserved under time invariance”), where conservation laws come from, etc.

I feel like most first year physics courses are almost taught as a survey: mechanics, statics and angular dynamics, thermodynamics, fluid mechanics, optics, electromagnetism, cosmology. But there’s very little effort to present the framework that undergirds all of these and makes them all the same subject.

They don’t have the math yet. Most students are taking calculus 1 concurrently with the first semester of intro physics (which is where mechanics is, of necessity, introduced) so anything more than a simple derivative or (later in the semester) integral is too damn much.

It’s a problem physics programs are well aware of, and as secondary math education deteriorates the issue is getting worse not better.

At my school they offer two flavors at the freshman level: calculus physics and non-calculus physics. I really can’t imagine how you can get very far in a physics without calculus, so I’m not sure what is in that class. But the fun part is that, as nearly as I can tell, they leave it up to the students which they should take, and don’t really look to see how prepared they are.

I took a year of non-calculus physics at my local community college when I was in high school. Then another year and a half of calculus physics after that in college. The non-calculus physics course was my absolute favorite science course I ever took: rigorous, thought provoking, fascinating, difficult.

Yeah, this makes sense. Electrical engineering curriculums face the same issues, so that a significant fraction of course-work is simply math foundations: complex variables, domain transformations, statistical analysis, multivariate calculus, and linear algebra are taught during courses on EM fields, communication theory, control systems analysis, etc.

The standard split is that bio/pre-med students are required to take at least algebra-based physics, while physics/chem/engineering students are required to take the calculus-based one.

There is also generally an even lower level survey class that’s primarily conceptual for interested non-science majors.

I teach both and truth to be told the differences aren’t enormous, since as I mentioned you can’t do much calculus in that first semester anyway with folks only just taking calculus 1 concurrently. At that level it’s more about instilling an understanding of the concepts and a baseline for problem solving methods (i.e. a good intuitive sense of how forces work on a system, the difference between velocity and acceleration etc). The intro courses are, as you say, surveys for better or worse. Many attempts have been made at institutions I’ve worked for to try to retool things to create a deeper intro mechanics course, but no one’s yet found a way to do it within the restrictions of a four year schedule with students prepared at the level we have.

Gotta say, in another life I think I’d be a physics prof in a heartbeat. I would love that job.

I am not a science guy, but I have to speak in general in favor of surveys. There are students who will take only a survey class in the field. A good survey class will give them a broad overview—that overview serves as a foundation for further study, of course, but it’s also part of a liberal education.

I used to teach in a college where the history prof (yes, there was just one) didn’t appreciate the survey. She wanted to go more in depth particularly in her field and had activities that were potentially engaging so she generally got good evaluations, but her students—particularly her social studies ed students—weren’t prepared for what they needed. A good, broader survey would have served them better.

I completely understand the struggle between breadth and depth. I used to teach Intro to Education which was required for ed majors, but others could take it as basically a sociology elective. There were parts of the course (technology, intercultural education, special education, assessment) that were covered in separate courses for majors and/or were integrated in basically every majors course. It was a balancing act in deciding what to cover for a) foundational purposes and b) an overview for students who weren’t continuing in the field. I have adjuncted US history, world history, and Western Civ surveys, and there’s a similar tension although not as significant since most students in those courses aren’t going to major in it.

Sorry for the rambling. TL;dr—I really like survey courses!!

You touch on some really interesting issues. When I started teaching at the college I am at now, over 20 years ago, I was teaching intro World and American History surveys, and a handful, like literally one or two, upper-level history courses, all with fairly general themes. The colleges is a professionally focused institution with zero liberal arts or humanities majors, and most of the programs are pretty full so that students don’t have a ton of electives they can take.

About 15 years ago we swapped over to an integrated, interdisciplinary approach to gen ed, ditching nearly all the single-discipline survey courses from the general education pool and replacing them with a “Core Curriculum” consisting of courses that focused on using different areas of the arts and sciences (mostly humanities/social sciences; we couldn’t get the math or science folks to shift on their survey courses) to look at relatively broad themes. Our logic was that, with no majors for students who liked a humanities survey to jump into, and limited elective space anyhow, having students take the same sort of generic gen ed surveys they could get for a lot cheaper at a community college was not exactly a winning proposition.

The new system worked quite well, really, and we are now in the process of rolling out version two of the beast, with an even more direct focus on critical and integrative thinking competencies and interdisciplinary and experiential work. The trade off, and there always is one, is that unless a student is getting an Education degree and needs something for certification, no one takes a single-discipline survey course in the humanities at all. The courses they do take end up covering a wide variety of topics due to how individual professors tailor their versions, but there is no guarantee anyone will even be exposed to, say, American history in general, or American government, or world history, or a dedicated literature class, etc.

I taught surveys long ago at a state university, too, and personally I loved teaching them. The students, well, I found that mostly very little stuck with them from their survey courses. Students in the major usually tested out of the basic courses anyhow, and the engaged ones you had left were few and far between. The idea that students need to be exposed to a variety of different disciplines is sound, though survey classes as a way of doing this are just as problematic as the way we are doing things by focusing on intellectual skills using a wide variety of humanities subjects.

One issue too that comes up all the time in things like history, which is where my Ph.D. is for example, is that getting anyone to agree on what should go into a survey class is nightmarish. I’ve worked with faculty whose idea of a solid American history survey consisted of essentially The Golden Story Book of Great Americans, and those whose approach was so theoretical and abstract that even a grad student would faint dead away. Same with literature, poli sci, anthro, etc.

Math and science are perhaps different kettles of fish. I can definitely see how non-tech/science majors would benefit from surveys in physics, chemistry, biology, etc., and at my school they of course have to take at least one lab science. As we have no actual majors in any of those fields–though our game programmers and software engineers in general need the physics and math for sure–the surveys don’t have the same burden that intro courses might have elsewhere I guess.

West of Eden by Harry Harrison immediately popped into my head when I read this.

I feel like this could also go in the “what could possibly go wrong?” thread.

Love it.

Is that the one where some kind of creature eats all of the hair and nails off of a person?

It is! Co-evolution of humans and reptiles, the humans are kinda stone age, the reptiles have super-advanced biotech things.

This is so awesome.
