What level of physics and how much maths do you know?

If you are not good with maths: https://lightandmatter.com/cp/
If you are not good with calculus: https://lightandmatter.com/lm/

i am sophomore right now, i have algebra 2 this year i just really want to progress my math understanding. i pick up on math subject very quickly, which is why i want to learn new math stuff because math class gets very boring after the first day of new subject.should i study calculus first?

It's up to you. Do you have any particular goals in mind, or is it just to satisfy your curiosity?

Pic related. Dude drops major redpills all throughout.

Learn trig as well if you want to do calc

>motion
- A force is a push or pull
- Space has an x y z and time dimension
- Displacement is when one object changes its ​position to another location
- Velocity is the movement of an object in a given direction at a certain distance over a ​time
- Speed describes how fast an object moves ​over time
- Accelerationism is the change in velocity
- Most objects have resistance towards motion we call this mass or inertia
- pressure describes the amount of force in a given area
- when an object is in motion it stays in motion until its hit by another force likewise an object at rest will stay at rest
- When a force hits an object that object moves in proportion to the force that hit it
When an force hits an object an equal force hits back
- Energy is how much distance a force travels
- Energy cant be produced or destroyed only extracted and transferred
>heat
- under KMT(no google it yourself dumb dumb) the average speed particles move at is referred to as its temperature, faster moving particles higher temperatures
- particles like to spread out causing diffusion and likewise heat diffuses naturally into areas of lower heat causing lower particle collisions and hence lower temperatures
>light
- light is made of fundamental particles(particles that cant be divided into smaller pieces) called photons, photons often come from radiation released as light(radiation can be described as the diffusion of energy)
- light travels in waves often times in straight lines
- visible light is waves of light that are small enough to contact the human eye with red light being the lowest energy wave and purple to white light being the highest energy wave, the smaller the light wave the higher the internal energy per ray of light
- light is affected by its surroundings and reflects, refracts(changes direction through a surface) or goes through different surfaces
- the speed of light in a space where it cant collide with anything is the fastest speed objects can travel at
>sound
- sound is caused by the vibration of particles and is recently discovered to be a fundamental particle
- visible sound is sound that travels in waves small enough to be heard by the human ears
- areas without vibrating particles cannot create sound
- sound can create a force through the vibration of particles with some studies showing fundamental sound particles can transmit really tiny but existant forces
forces
>electricity
- Objects have charges that allow them to experience forces when in an electric field
- a charge is a quantifiable measurement of how much an object can or cannot create a force on objects with opposing charges
- negatively charged objects attract positively charged objects while same charges repell each other
- electrons are negatively charged fundamental particles while protons are positively charged, neutrons have no charge
- current describes how many electrons flow through a given region
- voltage describes the pressure of electron flow
- resistance describes the resistance or "mass" towards electron flow
- an electric field is like a force field( a region where theres alot of forces moving in a specified or unspecified directions) but the force is composed of charges

And that's most of classical physics, if your working with modern physics than I have to write about QM, relativity(bad but somewhat helpful summary,how the world of physics behaves isnt the same everywhere on a large scale and depends mostly on what's being observed and how fast objects are moving as the slower an object moves the faster it experiences time compared to objects moving at faster speeds(we call this time dilation))

If your interested in engineering read this after reading through my artistically long post

Is this the guy who thinks both Lenin and Stalin were Jewish CIA agents?

>>6895
I have the long term goal of learning more about physics, but it also is for myself since i love math and learning new topics in it.

>>6898
just found a college trig textbook pdf, should that work well? i already have some understanding from what was taught in my geometry class.

Nah he writes a lot against imperialism. Not only that but his theories go in line with dialectical materialism and expose systemic errors in culturally-biased research that have become accepted purely because of the profit motive. For example take the kinetic energy equation. The modern one in bourgeois science books (E=1/2mv^2) exaggerates the importance of velocity. Applying this model to the work environment creates the guise that in order to produce a larger output, more velocity is required ie. the workers have to work faster to maximize the transfer of energy and productivity. Thus the porky indoctrinates the masses with this to increase his rate of profit. Every marxist should read mathis.

Even if you ignore the blatant anti-Semitism, it's still full of gems like this:
> But since we know Socialism was manufactured from the ground up by Capitalists as misdirection, we may assume all these Marxist and Communist documents are manufactured, forged, or faked in some way.

I agree he uses leftcom talking points too much in his works on history, he should have stuck to physics

>>6908
some parts are still based ngl

The guy is deranged, even Foundation Encyclopedia Dialectica makes more sense than him.

WHAT
this is by far the most deranged thing i have read since i stopped visiting /sci/

These sound really cool but I did not watch them yet: https://theoreticalminimum.com/
