I have started studying math, but I am unsure of the right path to take. I have my old middle school textbooks (6th, 7th, and 8th grade) that I am hoping to whiz through so that I can take on pre-algebra which I really struggled with. Then after that is I plan on studying: Algebra -> Geometry ->...

Thanks for the suggestion! It will be good reading as I slog through the prerequisite Maths.

I am definitely not strong with algebra or trig, so I may need to brush up on that before doing Calculus.

What maths will I need to learn? Calculus? And for Physics, is there a text that covers the prerequisites to understand String Theory? I just need to chart a path for myself. Also, Eric Clapton is the goat.

So basically I have no chance to learn this? That’s depressing :(

I don't want to pay for college courses. Is there a textbook that explains it?

Hi, I have heard all this hype about a Physicist named Ed Witten and how instrumental he is to something called “String Theory”. I tried listening to one of his lectures on YouTube and reading one of his papers and I couldn’t follow anything. I was hoping to figure out the prerequisite...

Thank you for the tips! I will make sure to keep these in mind.

1. I am a US citizen looking for a job in the US 2. Yes, this past May and June 3. There were career fairs but no interviews came as a result.

Recently graduated with a degree in Computer Science. I have been sending applications daily and got to final rounds with a FAANG company but they went on a hiring freeze. I recently again got a final interview with another FAANG company at the end of the month and have an online assessment with...

So here is my next attempt PEspring = Wgrav + KE (1/2)kx^2 = mgsin(theta)x + (1/2)mv^2 Is this correct?

This is my attempt PEspring = 1/2m(Vx^2 +Vy^2). I know this is not right. I am confused and have been trying to figure this out for two days now. I do not know how to incorporate the angle of the launcher.

I am really stuck and confused. I just need the equation. Thanks! Here is my attempt at solving: PEspring = 1/2m(Vx^2 +Vy^2)

Oops. took out the square when I took out ##r^{2}##. I got the answer right for the first part. But for some reason I am struggling getting the percentage with the rod wrong. For the rod I get ##24.75 mg * m^{2}## and for the actual Inertia I get ##25.02 mg * m^{2}##. Then I take ##(1 -...

Oops. It's 30 that will make up the entire length So would a correct formula with a series of distances be: ##I_{O} = 15mr^{2} + 2mr^{2}(2 + 4 + 6 + 8 +10 +12 + 14)##
