"General physics" vs. "Classical physics"

Click For Summary
SUMMARY

The discussion highlights the distinction between "General Physics," as exemplified by Halliday's textbook, and "Classical Physics," represented by works like Fowles and Purcell. General Physics often employs simpler mathematics, which can lead to frustration among students seeking deeper understanding. In contrast, Classical Physics utilizes advanced mathematical concepts, such as vector calculus, to elucidate complex topics like circular motion. This difference in approach can significantly impact a student's appreciation of physics, particularly in undergraduate programs where course structures vary widely.

PREREQUISITES
  • Understanding of basic physics concepts from General Physics courses
  • Familiarity with calculus, particularly integrals and vector calculus
  • Knowledge of classical mechanics principles
  • Awareness of different physics curricula in undergraduate programs
NEXT STEPS
  • Explore Fowles' "Analytical Mechanics" for advanced insights into classical mechanics
  • Study vector calculus applications in physics to enhance problem-solving skills
  • Investigate the curriculum differences between algebra-based and calculus-based physics courses
  • Review Halliday's "Fundamentals of Physics" to understand its pedagogical approach
USEFUL FOR

Undergraduate physics students, educators designing physics curricula, and anyone interested in the pedagogical differences between General and Classical Physics.

Dear fellows,
I wonder about what is the difference between general physics (i.e. Halliday and the like) and the classical mechanics/electromagnetic theory/etc sequence (i.e. Fowles, Purcell, etc). Someone told me that it is only about the mathematics required, but in that case, is general physics needed at all? I mean, a book like Halliday seems to avoid slightly more complicated maths (if you can say that integrals are complicated at all) like the plague.

Actually, I'm only complaining because I'm an undergraduate student (major in physics) and the General physics course is so annoying. It makes me think that physics is only about cumbersome text-problems that involve cars or other ridicule stuff. What is worst, with so little mathematical insight that you think perhaps you are just a chimp...

On the other hand, I came across Fowles' book on analytical mechanics and, suddenly, many things started to make sense. For example, circular motion using only algebra is so difficult, but when you look through the glass of vector calculus it become so easy. And, what is most important, so beautiful.

So, can someone give me some insight here please? Thanks in advance!

A lot about can depend on how the program is set up at your university. Unfortunately the reality is that most students who take first-year physics take it because it's a requirement for medical school or the program they've signed up for an have little interest in the "beauty" of problems in classical mechanics. Some schools will even have separate first-year classes for physical science majors (ie. a calculus-based physics), and everyone else (algebra-based). Other schools will lump everyone into the same course and more often than not, end up teaching to the lowest common denominator. If that's the case for you, just get through it. Things will get more interesting in your second year.
 
Dear Choppy,
thanks for your answer. I think you are right: just look forward and be cool, although in my case we are talking about third year.
Best regards!
