How much does high school contest skill improve your grades in university math courses? Currently I find that all the contest tricks that I've learned play almost no role in my university courses, and studying my textbooks is all that matters now. Any clever thinking I had for those contests...

Hi, I have a definite interest in mathematics and physics...it has long been a dream of mine to become an astronomer instead of an astronaut. But I wonder if it's too late for me to do that. First you should probably have a little background information. I'm a 20-year-old high school...

Hi. This may not be the best place to ask this, but I have a friend who is very interested in quantum mechanics and is trying to learn a lot of it on his own (he's told me that he knows the equivalent of someone who has taken 6 months of a quantum physics 101 course). We're both freshman in high...

Ok I am new to physics forum but I am sure if I am going to get help ill probably get it here, this problem has gone UNSOLVED by everyone who has tried it to include my physics and calculus teacher. Here is the problem: There is an object 10 Earth radii from the CENTER of earth, it is...

I am currently a junior at a high school, and I've been recently scheduled for my senior year in hs. Anyway the classes related to physics i took are, I took Calc AP, Phys AP, Chem AP. They are AP, they should cover me and prepare me for physics in college right? I hope so. After reading...

is it a good idea to, let's say, stay in a high school where your grades are high and you're highly ranked because all the other students don't care about their education and the teachers don't as well, as opposed to transfering to a different high school where you can actually learn something...

Hello, Since few days, I was looking forward to start some pre-calculus classes...but I am kind of confused with the 'types' of classes offered. Oh and I am in 9th grade...prob. I'll take it next year(its not available in my school, I will probably have to learn somewhere else,can anyone...

Hey there, I am high school student in South Africa, and I'm passionate about maths. I'm not too sure why, but it's fascinating. In South Africa we don't do courses, we follow a set curriculum, and we have a program similar to the AP program in the US, which I take. I'm in grade 11, and...

hi, I am at high school level, I just started with vectors,but topics given in my school books didn't seem enough to me, they are just too brief and unorganized. could anyone tell which book could best for me, to study vectors?

As exam time is right around the corner I'm looking to "brush up" on the cirriculum of my physics 11 course... I have looked at many of the university videos on here, and although they are very interesting and broaden my physics perspective, they are far out of the scope of my course, so that...

Hi there. I'm having issues with a high school lab that deals with acceleration of objects down inclined planes. At the top of my lab questions, there's a simple diagram (just a triangle with a rectangle on the hypotenuse, representing a cart), and one of the questions pertains to it: What is...

I'm a senior in High School, and took BC Calculus as a Junior and this last semester a 1-semester Calc 1&2 honors class, mainly for those those who took AB in High School at the University of Utah. (It's surprising how bad you can do on the AP test and still get a 5). I'm signed up for the next...

Several friends and I have a great yet unexplored interest in Astrophysics, and interesting Math not taught in the typical high school course.

Today I asked an upper-classman friend of mine what she was doing currently in pre-calculus. She told me she's doing differentiation, I woulda guessed that. However, she has a friend in calculus AP and I asked her what they did in AP, if she knew, since I'm planning on taking AP calculus my...

Hi, uhh, well I don't exactly know how to start here. I am a sophomore in high school and I am really interested in astronomy and physics, so obviously this was the first place for me to look. The thing is though, I don't know that much about neither astronomy or physics (due to my counselor not...

Why did textbooks (when I was in high school 5 1/2 years ago) always associate photons with the visible light part of the EM spectrum. Wouldn't the radio, x-ray, gamma, etc. areas of the spectrum exist as photons too? What about the transverse waves; would it not form a helix shape instead of...
