    Is the collapse of a wave function deterministic or random?

    Also, please don't choose Bohm or the consciousness thing. :smile:

    What is the Exact Meaning of F=dp/dt?

    F=ma, like the concept of frames, is purely empirical from the beginning. Force and momentum are circularly defined.

    What causes current decay in plasma collisions?

    Thank you. So in this "simple picture", are we neglecting current decay due to ion-ion collisions? And I guess electron-ion collisions are too effective to ignore.

    What causes current decay in plasma collisions?

    1. Current is induced, I assume no collisions happened. 2. The current dissipated into "heat". My problem is about the concept of heat.

    Electric Potential Energy Concept

    Your second point is true as long as you offset the potentials of all the charges in the system wrt. the ground you take.

    Electric Potential Energy Concept

    q(Vf - Vi) is correct for the work done by the force opposing the electric force. If the work done by electric field was being considered, it would be q(Vi - Vf).

    What causes current decay in plasma collisions?

    Hello PF, This has been frustrating me for a while: The plasma inside a tokamak is being heated by current induction, which accelerates the ions and electrons in specific directions, thus the velocity of ions increase. These ions collide with each other, eventually randomizing the motion. Now...

    Is the cat alive, dead, both or unknown

    Thanks for the correction.

    What absorbs Ultraviolet radiation?

    TiO2 absorbs UV well and it is also very resistant. Beryllium and these are other materials used.

    What absorbs Ultraviolet radiation?

    Your English is confusing, but are you saying that UV is re-emitted as visible light in the atmosphere?

    Is the cat alive, dead, both or unknown

    Unknown, or more technically, in the superposition of two states.

    Induced Electric Field inside Faraday Cage

    Thank you both.

    Induced Electric Field inside Faraday Cage

    His first sentence sounds to me like he has understood the question differently, as if the field is generated inside the chamber.

    Induced Electric Field inside Faraday Cage

    I am asking what if the solenoid is outside the chamber, in the middle of the toroid.
