I have started a class on the analysis of calculus. We are three weeks in and have covered some basic set theory, fields and axioms, and now we are beginning induction. It is a very rigorous course and I hoping someone might know of some helpful resources that could aid me throughout it. Ideally...

I've been relying on Wikipedia and some other questionable sources for a basic understanding of these studies, and i don't think I should rely fully on these sources. If anyone can point me to a place that is reliable I would greatly appreciate it.

Hello, I am struggling with vectors, and general problems tagged along with them. How can I get some more practice aside from my book? What are some trusted resources that work well? What is your personal experience with vectors? Are (were) they a challenging obstacle for you? What is the best...

Hi, I just started college and was pleasantly surprised to see that a lot of my classmates know a lot about different engineering stuff. Some would know all the parts of a car and maybe how the ac worked etc... for me other than programming I was ashamed of how limited my knowledge of these...

Hi, I was just wondering if there were any good resources/sites for learning to plot and solve differential equations and any other math for that matter, specifically in Python? The physics program at ASU is great but we aren't really given any class time to learn how to program, it's all on our...

Hi there, I was just wondering if anyone knows of any good materials, books, websites, Youtube users etc for me to teach myself Complex Analysis for school. Some good practice problems with answers and explanations would be wicked too. Thanks :)

I saw the samsung edge released and I thought it would be very cool if I learned how it works. So are there any patents, blueprints, etc. that is on the curved display technology? I want to see it for myself because it's cool. Is there a way to see other patents or blueprints legally?

Hello, I was wondering what websites you would suggest for resources? Physics, mathematics, programming(any language), and engineering? By online resources I was thinking resources like wolfram mathworld. Any online resource as extensive as wolfram mathworld would be great.

I am self-studying Physics in the second year of my undergrad(too late i know) as I never really understood many basic concepts in my high school as clearly as i now do. In my enthusiasm to teach myself Physics I bought a number of books but none seem on par with stuff described on many forums...

Hi, I'm looking for an in-depth guide/tutorial about how to use and understand SI notation. As it stands, I've realized it's a source of confusion in physics for me because i never took the time to properly learn. If anyone knows of any resources which would help me to understand it would be...
