    Is computation synonymous with functions in computer science?

    Pity, I don't know rather it helps you, but all the computer could do is addition... Minus is plus with opposite sign, multiple is many times plus and division is many times minus. That's computer in real.

    Distance traveled given acceleration?

    Consider a = delta v/ delta t where delta's are finit then S = delta v * delta t = a * (delta t)^2 So it seems for a moment.

    Complex variables and classical mechanics

    Not exactly complex numbers, rather trick with I = Sqrt(-1). It appears in both equations and successfully excluded, giving correct answer.

    Complex variables and classical mechanics

    Once, looking through elementary school textbook I have encountered a problem dealing with axis orientation. It was very strange, but without using complex unit this problem couldn't get proper solution.

    Momentum, position vector dot (scalar) product action

    Real lagrangian dimension is not Energy

    Why Does the Lagrangian Depend on Time and Position?

    No derivation or experiment, pure theorie supposition...

    Uncertainity Principle: possible to know the momentum and position?

    There present h/mc value, but if we consider h/mv where v is nonrelativistic then it seems all right.

    Logic: All Comedians are Funny?

    First say is overall. Second is exasperate. So they mean differ.

    Why can photons only move at the speed of light?

    Is it the only way for photon to move at c? It's just max possible or?

    Photon Mass: Is It Really Zero or Infinite?

    Possibly photon has some mass, but doesn't interact in gravitation, while it's an electromagnetic transmitter.

    Independence of Energy and Momentum Conservation

    Now you simply took from the very beginning that P1 = F12 P2= F21 I.e. P1 = -P2 and then easily concluded P1 + P2 = 0 Seems like it's NOT quite correct.

    Independence of Energy and Momentum Conservation

    1) Strange tricking: R = r1 + r2 dR / dt = r1/dt + r2/dt V = v1 + v2 dV / dt = dv1/dt + dv2/dt A = a1 + a2 Proceed? 2) How the j sum become jk sum?

    Independence of Energy and Momentum Conservation

    Excuse me, could you explicitly derive momentum conservation equation (don't forget, momentum is vector value). Many thanks before.

    Differential Equations in simple mechanics?

    I could easily agree with you latest example. Us just wanted to underscore the difference between "definition" and "equation".
