    High School Quantum Teleportation Question from a Curious 10 year old

    Q: How do the scientists actually entangle the particles. A: The particles are already entangled. It is a condition of their physical existence in nature. The scientists do no invoke this condition. Q: How does zapping the entangled sending particle with a laser actually set it off to teleport...

    Undergrad Can angular momentum be applied to non circular rotations?

    They taught you using a circle since it is the easiest to visualize and grasp the concepts. Just like in entry level physics when they have you calculate aspects of a ball rolling down an incline they do not include atmospheric resistance, surface frictions between the two items, or atomic...

    Undergrad A perfectly stiff wheel cannot roll on a stiff floor?

    Envision: High tinsel steel ball bearing, High tinsel steel plate, no deformation of either will occur, however, apply any force to the bearing either directly (even with a simple magnet to avoid physical contact) or by tilting the metal plate (imposing gravity) and it will roll quite well. No...
