    Programs Should I major in Physics or Geology when I am terrible at math?

    Again, stressing that videos cannot replace taking the course. You need to be challenged by the tougher concepts not offered by the rigged nature of video problems. I'm not advocating that videos are overall better than textbooks. Obviously with the harder courses you NEED the text and an...

    Programs Should I major in Physics or Geology when I am terrible at math?

    Also, it is worth noting that today, many videos can help teach ALMOST as good as a textbook (provided it is guided by a professor or coursework, and for the simpler courses). I'll never say that reading a textbook is not worth it or hurts or should be abandoned. The textbook is a great source...

You OBVIOUSLY need the course and a knowledgable professor to help teach you how to APPLY the mechanics and concepts...

    Simple pendulum in different situations

    Equation needed: T=2π√(L/G). If the water is uniformly distributed and also fills up the entire sphere (to avoid sloshing which changes this whole problem), and we're ignorning friction, expansion, etc... Then no there should be no difference. The bob's center of mass remains in the center of...

I got my GED in HS and left for the military to go serve in Iraq. The last level of formal education I had was HS Geometry. After 9 years of service, I decided...
