    Tips for Keeping Your Books Clean: Highlighting, Marking, and Note-Taking Habits

    Hmmm, pretty divided. I guess the growing prices of books to some extent are the reason.

    Tips for Keeping Your Books Clean: Highlighting, Marking, and Note-Taking Habits

    I use sticky notes as well. They're great when a page references a diagram because I usually redraw it. When the book is cheap enough, I usually own two. Sometimes I highlight since it makes referencing a little more easier, especially when the book is wordy. I would like to add that my...

    Tips for Keeping Your Books Clean: Highlighting, Marking, and Note-Taking Habits

    Keeping books "clean" Do you guys/girls highlight, make marks, write notes, etc. on your books? I've found myself trying to keep my books as clean as possible. I guess cause some I consider part of my collection and some because I may want to sell them eventually. I was just curious. I know...

    Regenerative braking for bicycle

    Hi, I was wondering about the idea of having torsion springs as a means to store kinetic energy when braking in a bike. I've thought about using compressed air but I am having troubles designing a gear system for both so that you can get the energy back to accelerate from rest. Can anyone...

    Are people who are good in math good in physics as well?

    This doesn't apply to everyone, of course. But, this is interesting. When I took my Integral Calculus class before, we were doing a kinematics problem and one student asked what was the difference between a Kilogram and a Newton. My professor had no idea, and one of my classmates who was also in...

    Books for a Course of Private Study

    Those are some awesome books. By the way if you don't mind me asking, I've wanted to try Bamberg/Sternberg but because I don't have the solutions to the answers I didn't. Can you tell me the methods of studying you used for the book? If it's not so much to ask, maybe for all the books. I'm...

    Solving the Equation for Bacterial Growth in Experimentation

    Thanks, I just got it. Can you tell me why I needed the limits? The other one before this didn't have the R (reduction) so the equation was just N = N_0e^{Kt} When I was solving that I didn't need limits.

    Can You Simplify csc(θ) - sin(θ) to cos(θ)cot(θ)?

    Muliply both sides by some thing that will make it look more familiar.

    Solving the Equation for Bacterial Growth in Experimentation

    The answer in the book is, N = Ce^{Kt} - (R/K)(e^{Kt}-1)

    Solving the Equation for Bacterial Growth in Experimentation

    I tried that but I just can't seem to get it right. I don't get the same solution as the book. By the way the question is No. 22 of Section 2 in Chapter 8 of Boas' Math Methods for those that have the book. I integrate those and get, (1/K)*ln(KN-R) = t + ln(C) , C is the initial number of...

    Solving the Equation for Bacterial Growth in Experimentation

    Homework Statement The growth of bacteria is proportional to the number present but is being reduced at a constant rate for experimentation. Find the equation for N Homework Equations d(N)/dt = KN-R , N = number of bacteria, K = proportionality const., R = reduction rate. The...

    Mathematical treatement of electrodynamics

    Sorry for the off topic question but when you went through Bamberg and Sternberg's book was it for a class which gave solutions to the exercises? I want to go through the book but I do not like not knowing if my answers were right. If it was for a class, I was wondering if it had a website that...

    Which Books Are Best for Physicists Learning Manifolds and Differential Forms?

    Does anyone know of a solutions manual to Bamberg and Sternberg? I'm self-studying and I want to make sure I get the right answers.

    Which Books Are Best for Physicists Learning Manifolds and Differential Forms?

    The reviews on Amazon kind of deterred me from getting the book. Is it worth it? Any comments?
