What Are the Prerequisites for Beginning a Self-Taught Education in Physics?

Click For Summary

Discussion Overview

The discussion revolves around the prerequisites for beginning a self-taught education in physics, particularly from the perspective of an 8th-grade student. Participants explore various resources, mathematical foundations, and programming skills that may be beneficial for learning physics independently.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant suggests reading "Physics for the IB Diploma" for a college freshman level understanding and "Physics for Future Presidents" for conceptual insights without heavy math.
  • Another participant emphasizes the importance of mastering algebra, geometry, pre-calculus, and calculus to prepare for physics studies.
  • Some participants recommend using Khan Academy for algebra-based physics, while others express skepticism about its depth and usefulness.
  • There is a discussion about the relevance of programming skills, with some advocating for Java due to its widespread use in physics simulations, while others question the necessity of programming altogether.
  • Concerns are raised about whether in-depth knowledge of trigonometry and calculus is essential for understanding classical mechanics.
  • One participant mentions that physics can be learned at various mathematical levels, including without calculus or even algebra, and recommends "Conceptual Physics" by Hewitt as a resource that requires minimal math.

Areas of Agreement / Disagreement

Participants express a mix of agreement and disagreement regarding the necessity of certain mathematical skills and programming knowledge. While some advocate for a strong mathematical foundation, others suggest that physics can be approached with less rigorous mathematical prerequisites. The discussion remains unresolved on the best approach to self-taught physics education.

Contextual Notes

There are differing opinions on the depth of mathematical knowledge required for learning physics, and the effectiveness of various educational resources is debated. Some participants highlight the potential for approximations in physics calculations without advanced math, while others stress the importance of a solid mathematical background.

Hello!

I'm an 8th grade student with a strong interest in the field of Physics. I was wondering what prerequisites I should have to begin learning Physics, and what I should read/do to dive into a self-taught education in Physics.

I am currently in the process of reading "A Brief History of Time" by Stephen Hawking and watching some of the Feynman Lectures on Physics.
 
Physics news on Phys.org
There's a good book called Physics for the IB Diploma by Tsokos which is used in some HS AP courses that is pretty good. That should give a college freshman level of physics understanding.

For a conceptual book consider Physics for Future Presidents by Richard Mueller, good book for concepts without too much math.

Pay attention to your math: algebra, geometry (trigonometry), pre-calculus and calculus learn them well enough to help other students and you should be well prepared.

Learn some java programming. Generally useful for some projects. and/or Matlab (clones available: Freemat, Octave...) used by physicists/engineers to do assignments, simulations and other projects.

Checkout the Open Source Physics website www.compadre.org for computer simulations.

and Khan's Academy for videos on Physics and Math topics.
 
8th grade eh? Impressive.

Have you started calculus? I think the Feynman videos are calculus based physics. I'd look at the stuff on Khan Academy first. He has a bunch of algebra based physics that allows you to do calculations and grasp the concepts.
I've heard from a lot of people that the MIT stuff on youtube is excellent but I'm sure that's calculus based as well.

Why use Java over a language like Perl (which I know)?

From what I've watched, the Feynman videos are a lot more conceptual (I may be wrong, I've only seen three).

As far as Mathematics goes, do you think I need to go in depth on Trig and Calculus? I haven't taken either yet in my regular schooling.

Perl is a good scripting language but Java is everywhere. One example is the Open Source Physics link I mentioned where people are doing simulations of physical systems using Java. There are many more libraries and tools that support Java and many more software engineering related jobs in Java. Java is also a cross platform language. I can write code on Windows that runs on Linux or MacOS without worrying about platform differences for the most part.

Yes, unfortunately you do need trig and calculus to do Classical Mechanics. But as I said, Khan Academy has excellent algebra based physics where you can still learn to do calculations. The only thing is that they will be approximations. For an example, to calculate the torque on a see-saw you need to use integrals but you can get a good approximation with algebra.

If the Feynman videos are conceptual then it's all good.
 
There are lots of different mathematical levels at which you can learn physics. You can do it with calculus or without. You can even do it without algebra.

Khan academy is very superficial; I wouldn't waste any time on it.

Programming is totally unnecessary. Do it for its own sake if it interests you.

A good book that doesn't use a lot of math is Conceptual Physics by Hewitt. Many public libraries have it. It assumes only very basic algebra.

Here are some free books that you might want to browse through: http://www.theassayer.org/cgi-bin/asbrowsesubject.cgi?class=Q#freeclassQC
