One path would be to develop a computer science and programming background that can convince employers that you're a better hire than a CS student for a software development position. There are positions like this where a a physics degree is appreciated. Some people speak of self-study and...

I was and I was lucky. I did physics for my undergrad then computational science for my masters. I got a job doing some backend development without having any actual software dev experience (just MATLAB and some numerical analysis) because the people at the company were really nice. I learned...

So I've gone through the problem numerically and the results that I'm getting are identical, regardless of whether or not I include the viscous term ## -\frac{\eta Av}{mh} ## in the differential equation. So, without the viscous term, \frac{dv}{dt}=\frac{P}{mv}-\frac{1}{2m}C\rho Av^{2} While...

Ah OK. Thanks, mfb.

Just wondering how you determined the limit velocity to be ##V=\sqrt[3]{\frac{c}{b}}##.

Homework Statement I'm attempting to solve the differential equation, \frac{dv}{dt}=\frac{P}{mv}-\frac{1}{2m}C\rho Av^{2} where P, \rho, m, A, C are constants. The differential equation is used to approximate the velocity of a cyclist undergoing air resistance. It's actually presented as a...

I can appreciate math as a subject and all of it's achievements, philosophical aspects, etc. But I'm not going to deny that for the most part, doing serious math blows. Probably because I'm not very good at it.

I'm probably going to fail a 3rd year physics course at utoronto so if you want to do me a personal favour and strap the university for some cash, don't come here. :)

Oookay, here's a more serious attempt at an answer: The instantaneous axis of rotation for this problem is the axis where the cylinder is in contact with the plane. So, the motion of the cylinder can be described as a rotation around this axis (not sure how to imagine this, but ok). This...

Homework Statement Pretty picture: I am currently stuck on #1. Homework Equations Not exactly sure but... For #1, I assume the relevant equations are those relating the (i) gravitational force to momentum and (ii)torque due to gravity to angular momentum: (i) F = dP/dt (ii) K = dM/dt...

MAT157 is a good course. I recommend anyone going to UofT to take it, regardless if you're in Math&Physics/regular physics.

Thanks guys. \hbar :redface:

Homework Statement "A particle of mass m is in the ground state of a one-dimensional infinite square well with walls at x=0 and x=a. \psi_1(x) =\sqrt{\frac{2}{a}}sin(\frac{\pi x}{a}), E1=\frac{h^2\pi ^2}{2ma^2}* What is the initial wave function \Psi(x,0)? *h is supposed to be h bar, I...

Well -- not good. Hear me out: Studying physics in Canada, in my second year, almost finished the semester, and my marks are ****. I've hovered around class average (a range from D to C+) in most of my classes since year one and I don't feel like I can improve - rather it seems like the...
