I am wondering if there is such a subject as I am about to mention, I think it may be somewhere along the lines of computational fluid dynamics. Molecular/atomistic modeling of the components of a fluid to determine the flow properties of that fluid. This is a topic that would bridge the gaps...

In your opinion, what is the hardest topic in math? I don't really know many high high levels of math, maybe differential topology, or K theory, idk, what is it in your opinion? Oh, and don't say "some people think Calculus is hard" or other stuff like that, think of a high level math topic.

Hi all, I'm planning on doing a one-on-one tutorial my math department next semester. However, I don't know what topic I want to study, so I'm looking for some suggestions. Note that I'm interested in high energy physics (string theory, etc.) and theoretical condensed matter. I will be...

I am self teaching myself some of the math that will be needed for university physics. I have just finished Calculus 1 and most of 2. I have been told I should learn ordinary and partial differential equations, vector calculus and linear algebra. In what order should I learn these topics?

I am a high schooler, I have studied a fair amount of calculus probably up to about calc i level, I then skipped some stuff and did the vector calculus chapters in my calc book because it seemed interesting, I did grasp all the concepts, but I'll admit my integration techniques were not yet calc...

When you take a high school (A-Level) physics course at school, what are the first couple of topics you learn? I want to begin with the most straight forward basic stuff. I've looked around but can't seem to find a high school syllabus.

I wanted to ask from my intuition of Newton's First law that body in motion remains in motion. Assume we kick a ball on earth, we does our force of kicking stops. I mean ultimately it comes to a stop due to resistance and gravity. Now, assume it is in space with no gravity or air. When we kick...
