Discussion Overview

The discussion revolves around the initial topics one should learn when starting high school physics, with a focus on foundational knowledge and the relationship between mathematics and physics. Participants share their perspectives on the best starting points and the importance of mathematical skills in understanding physics concepts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests starting with the SI unit system and dimensional analysis, followed by Newtonian mechanics.
  • Another participant emphasizes the importance of a strong mathematical foundation before tackling physics, arguing that physics is fundamentally mathematical.
  • A contrasting viewpoint is presented, where a participant reflects on their own experience with a conceptual approach leading to difficulties later on, advocating for a more math-focused preparation.
  • A later reply acknowledges the need to learn pre-calculus and calculus as a prerequisite for studying physics.

Areas of Agreement / Disagreement

Participants express differing opinions on the best approach to learning physics, with some advocating for a conceptual understanding first, while others argue for a strong emphasis on mathematics before engaging with physics topics. No consensus is reached on the optimal starting point.

Contextual Notes

Participants' recommendations depend on their personal experiences and educational backgrounds, highlighting the variability in learning paths. There is an acknowledgment of the challenges posed by concurrent math and physics courses in college curriculums.

When you take a high school (A-Level) physics course at school, what are the first couple of topics you learn? I want to begin with the most straight forward basic stuff. I've looked around but can't seem to find a high school syllabus.

I guess you have some basic knowledge in algebra, geometry, pre-calculus and calculus.

I suggest the very first topic is SI unit system, and densional analysis.

Then, you may start to work with Newtonian mechanics.

By the way, if you are green in physics, you may start with some conceptual introductory text.

I disagree, respectfully of course. The conceptual route was the route I took 20 years ago, which resulted in my getting a BA in biology. A BA means you went the conceptual route and stayed there because you thought you already learned it and, well, I've got my degree, right, doesn’t that prove I know the material?

The problem is that it's a red herring. I'm now studying to reenter academia in an engineering-informatics area and my “conceptual” background is haunting me like a Halloween hangover. I’m having to start from the beginning doing the real math and science and I’m finding out that physics looks entirely different from the calculus point of view.

In any case, I would recommend going all-in with math first perhaps even a year or so you before get into physics. The reason is that physics IS math, and if you’re weak on the math you won’t get the physics and you’ll be wasting your time. Not only that, but you might get discouraged and dump science altogether. That is the real danger with being weak on math, because, believe it or not, math is really easier than physics. Math is a bunch of straightforward rules. Physics is a bunch of confusing word problems. Don’t go into that battle with a Halloween costume sword and a coat of arms with a BA plastered on it.

This is a problem with many college curriculums where they try to match the level of math classes being taught concurrently with the level-physics being taught. I personally think you should learn the math required well before you tackle the physics. But that is just me, the hard lesson I learned.

Guess I need to learn pre-calc and calc then :D and thanks Dirac :)
