Obis, I literally do that exact same thing for how I visualize bijective functions or linear combinations. An example I'd like to share for when I am thinking of a linear hull of a set of vectors. I imagine two sides separated by a line. On the left region I visualize what the n-tuples of the...

This might be naive, but I have no interest in having a high paying job. I'm if I'm able to get a PhD, whatever job I end up with give me sufficient money to pay for living expenses and money to help get my kids through school (if I have any). I don't understand why people want to be rich...

Thanks, glad it helps. I am currently living at home, my brother is a philosophy student and my parents are pretty supportive of education (they run a school themselves), so it is a really good studying environment. I'm sure I would find it very distracting if I lived on campus, in that case I...

I'm not in engineering, I'm doing Pure Math and the theoretical side of Physics. How would I not focus on courses alone? For me, that extra time that sets me apart would be working on coming up with my own ideas about math and getting some preliminary research interests. I have about 3 or 4...

I feel in a decent position to offer a bit of advice, but I only just finished my first semester in university in a Double Honours Astrophysics and Pure Mathematics program, I took: Calculus I, Honours Math: Proofs in Set Theory & Number Theory, Logic I: First-Order Logic, Introduction to...

I really appreciate everyone commenting with a massive amount of advice. It's been somewhat on an eye-opener to me about how a lot of people who have actually been through academia don't play it out to be as amazing as I (and many others) "think it is". In developing somewhat of a plan, in case...

Vanadium, is the situation similar for Mathematics? I'm not sure whether I wanted to go into Physics or Mathematics, which is why I am doing both for an undergraduate and taking an extra year (it can only help me). Thanks for the advice.

I'm finishing my first semester in university with a 4.0 GPA taking Honours classes, I'm working on a paper that will be published with a post-doc in Physics, and I have a summer research position lined up. I'm doing a double Honours Astrophysics and Mathematics program and I've already read...

You need to break up each vector into horizontal and vertical components and then add those together separately. So for example if I have a vector that is 5N 75 degree North of East, I would know that F_{x} = 5N cos(75), F_{y} = 5N sin(75)

So I've finally figured out question 3 but now I'm lost on 4. Any ideas?

Yes, I've got that far but how is it that "it tells me how far the beam has to move due to the change in the position of the ball" I conceptually understand everything you mentioned and I've calculated everything I just can't put it together.

Homework Statement A person with mass m1 = 69 kg stands at the left end of a uniform beam with mass m2 = 108 kg and a length L = 2.5 m. Another person with mass m3 = 67 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 9 kg (assume that the medicine ball is at...

What is your current career? What has drawn you to consider this option? It is all means possible if you really want to put your all into it and try as hard as you can, but you will be in school for a good 10 years at least in order to get a PhD before your career will start. Hey, I have a 93...

I've heard from a friend that I know that his first year math classes were ~400-500 students for things like Calculus I, and that the class sizes exponentially decrease over the years, so that when you are taking Lebesgue Measure and Integration, there are only about 15 people in the class.

Thank you for the responses! I talked to an academic adviser today who was not particularly helpful, but I think I am going to drop the course sometime soon and attend the lectures for the rest of the year so that when I re-take it I can be sure to get an A... I was mostly just unprepared for...
