Where do I begin if I want to self study physics?
How much maths is needed to know for a beginner?

>> No.11082123

>i want to learn qm/gr
dont bother, go back to popsci videos.
if you are serious start with mechanics, algebra and trigonometry

>> No.11082128

You need a basic working knowledge of calculus and vectors. Probably start with one of those big old broad 'physics for engineers' tomes that they use in first year like Serway or something to get context for everything that comes later. Then do classical mechanics properly.

>> No.11082172

yeah id suggest getting aquatinted with some vector algebra. it'll help you move onto classical mechanics + you can find most equations already derived and won't require any calculus for these basic topics. basic 2D projectile motion problems. momentum, work, heat, fluids,
simple harmonic motion, sound waves, light interference and diffraction.

that should keep u busy for a while...

you dont need to know calculus for basic physics just count the squares under the graph lol

>> No.11082223

>>11082210
not really. you cant develop any of the basic formulas symbolically without calculus

>> No.11082255

Honestly if I knew of a book that developed calculus and mechanics side by side I'd recommend that as a starting point in a heartbeat. The intuition from physics makes calculus come naturally and the language of calculus gives you a solid basis on which to build mechanics in a rigorous and general way.

you don't need to develop them.. they've already been derived into formulas..

To arrive at these equations you need calculus. My first semester of physics was in a public community college where tuition was $100 a year, and even there they took the time to derive them. How fucking shit was your freshman physics?

congrats on the CC education. I spent my freshy year learning physics like SR, optics and such. calc was for maths. completely transferable knlowdge, so im happy with the way it panned out.

No you don't pretty sure they were derived before calculus was even invented.

I guess we should just be taught that the half life of a substance is ln(2)/lambda without any comment on where that figure comes from, huh? Even if it takes 0.025 seconds to derive it? We should just write all the equations you need on the board at the beginning and have students memorize, without any explanation.

I have a similar question, how much maths is needed for chemistry? I'm planning on doing some self-study and then going to university. Please don't tell me I have to learn calculus and shit

>> No.11082469

>>11082351
Well, you should know Arithmetic and Algebra.
The (aptly titled) books "Arithmetic" by J.P. Serre and "Algebra" by S. Lang should be a good start

>> No.11082497

>>11082351
highschool maths should be fine.

early chem is basically all arithmetic and ratios

>>11082351
you have to learn way more math than you would like to.
analysis, linear algebra, complex numbers

if you dont have a passion for the programming language of this world, just let it be.
All science is basically math in the end, thats why everyone here has such a hardon for mathematics,
