    Why do most formulas in physics have integer exponents?

    F, m, a, L, etc are just symbols we use to represent concepts. If m=2 then m0.123=20.123. If you are asking why the equations that describe the universe are not strictly linear then it's an interesting question but not one I'm certain can be answered.

    Self Learning Calculus From the Beginning

    Yes, it is very much an introductory trig text.

    Self Learning Calculus From the Beginning

    Anything specific? I haven't used the book in 10 years but I remember enjoying it and it was recommended by the most respected professor in my math department.

    Self Learning Calculus From the Beginning

    I strongly suggest you spend the next year supplementing your math courses with a self-study of trigonometry. Buy this book and work through it until it is coldly understood. After that start tackling calculus.

    Is it possible to learn physics by myself?

    It takes a very, very, very special person to self study a subject like physics and have what could be considered a successful career. Whether you are one of these rare people I do not know, but the odds are against it. Study it because you enjoy it and see if it bears fruit.

    Is 19 credit hours too much?

    My calculus class was very rigorous, and very difficult. I am a math major that aced calc 1&2 with flying colors in my sleep. I really enjoyed my teacher and I learned a lot, but he is a known gpa killer. Most difficult exams I've ever taken, period. Other than that, I'm rather bad at managing...

    Is 19 credit hours too much?

    I took 19 hours last semester, and it wasn't fun but I passed all my classes with decent grades (but not as good as I hoped). I was pretty burned out by about the 8 week mark and finals week nearly gave me a nervous breakdown. Calculus 3 Physics 1 + lab Chemistry 1 + lab Western Civ 1 English...

    Age, future, anxiety.

    When you're 30 you'll look back and realize what a silly question this is. Study hard and good luck.

    Calc 3 - Tough/Messy Divergence Problem

    I really don't know. My teacher is rather "disorganized" to put it lightly and frequently makes mistakes on our exams. For example our last exam had 12 problems, and 5 of them had pretty critical errors and were not corrected until around an hour into the exam. He also assigns us problems that...

    Is kinematics/dynamics an everyday part of the job?

    My lab instructor invited me to sit in on his QM class next semester but I'm not sure my schedule will allow it. I bet it's awesome (and probably a little intense)! :)

    Is kinematics/dynamics an everyday part of the job?

    Thanks. I've heard the same sentiment about E&M from a couple other people. I'm definitely looking forward to it and I suppose I will continue taking physics courses and see how it goes.

    Schools 19 credits next semster, community college

    Depending on how comfortable you are with the math that will be covered in your algebra class I'd say your schedule is do-able. I'm currently taking 19 hours and it is pretty rough to be honest. I have calc3, physics 1 + lab, gen chem 1 + lab, english 101 and western civilization 1. I never took...

    Is kinematics/dynamics an everyday part of the job?

    I'm a math major currently in calc 3, and I'm also taking my first ever physics class. I've always had a very strong interest in physics from pop-sci books and Feynman's lectures, and I fantasized about doing some work in physics, possibly even changing majors. The problem I find myself having...

    How i can be a physicist

    I'd love to become the next Gauss! I'd even settle for the next Euler or Riemann!
