    Sum of 6th Roots of x^6 - 1 for n

    Sorry, of course there are; I foolishly put the others down to "complex" roots. Hmm. The 6 [real] roots are: x = 1 x = (-1)^(1/3) x = (-1)^(2/3) x = -1 x = -(-1)^(1/3) x = -(-1)^(2/3) That's the hard part done.

    What is momentum and how does it relate to running?

    Momentum is just a property that all bodies have (to be pedantic, an object does not need to have mass in order to have momentum). Think of it in a similar respect to inertia; imagine the sitution where someone is running at you, and you need to stop them. Now, the heavier the person is (the...

    Double Slit Experiment: Wave Interference & Particle Like Patterns

    Closing up one of the slits does not recreate any sort of observation. You're merely removing one of the possible paths for the electron (or whatever particle you're experimenting on) to traverse; as a result, there are no longer the two possible states (and thus, no superposition of the...

    Flux vs Fluence: What's the Difference?

    Fluence is the number of particles that intersect a unit area. Units: 1/m² Flux is the rate at which something flows through a unit area. The units depend on what you're measuring.

    Sum of 6th Roots of x^6 - 1 for n

    The only roots of x^6 - 1 = 0 are +1, and -1. Thus: 1^n + (-1)^n = 1 + (-1)^n

    Feynmann Lectures Volume III: Quantum Mechanics Intro Book?

    It's an excellent book, with a reasonably gentle introduction to QM. However, if you have not studied QM in much detail before, then you will likely find the math rather vague - you'll want to complement it with a more in-depth book. If there is much math involved in your course, then the...
