I am in my freshman year majoring mathematics,which I chose independently right after the entrance examination.I really admire the well-constructed logic and symbolic system in math,and I hope to have a good graps of it. During the first year, I take the mathematical analysis and advanced...

This is incredible. This archaeological find predates Stonehenge and the Great pyramids by 6,000 years and makes Stonhenge look like rubble in comparison to this 12,000 year old find. It's before stoneage man had agriculture, before the wheel, a time of hunter gatherers. This site brings up...

Im currently 15 years old and in grade 9, but I feel as though the math and science program at my school is moving terribly slow for my liking. What are some good physics textbooks for self-tutoring? And most importantly, what are some good calculus textbooks for self-tutoring? thanks!

Let's say I have a Gaussian sphere 1 light year across with synchronized clocks and sensors all over its surface. All clocks are co-moving, not accelerating, and the spatial curvature is negligible. If I have only one charge inside the Gaussian sphere, 1 centimeter from its surface for an entire...

I'm a 4th year physics major. I really love physics (specifically astrophysics) and my dream career is to do astrophysics research, but I've never gotten an A on a physics test (=> never gotten an A in a physics class) and I have no idea how to (I have some time to bring my GPA up because I'm...

I know that the definition of the second is a precise value based on some natural oscillation of a certain isotope, with a day being exactly 86400 (i.e., 60 x 60 x 24) seconds - whether or not the actual average day is a little different (and hence the leap seconds we've been getting lately.)...

A quick bit about myself, I went to college for 2.5 years right out of high school(I ended with a 3.0 gpa), that was about 5 years ago now. I am now wanting to go back to college to finish my degree. My major back then was Business Management, however I have lost all interest in that field and...

I am a 1st year Masters student. I started working with an adjunct out of department faculty member last semester and she mentioned that she'd fund in Spring. But now she says it won't be until this Fall. In the mean time I applied for a few TA positions, but didn't get any of them. Just heard...

Hi, I've made many threads on these boards over the past year about college and very soon, I will have to make a final decision. I wanted to apply to the USA but for a few reasons, wasn't able to do my SATs in time. I then decided to do a gap year and focus on a few other activities (mostly...

I've heard that using Lagrangians to solve mechanics problems is much more efficient and easier than using Newton's laws. In your opinion, is it too early for a student to learn lagrangians for a first year due to a lack of exposure of the mathematics required?

Junior in Highschool, and I'm only in Algebra 2 because my school system is stupid. (take algebra 1 in 7th grade, again in the 8th grade because my school doesn't have Geometry for 8th graders, and then come 9th grade, I was told that the Geometry classes were full and I'd have to repeat Algebra...
