…what the inductance per unit length is or the inductance of anything is one, the energy in the thing, the magnetic energy is one-half Li square and the energy can also be computed as we saw as epsilon rc square over two times the integral of the square…

…the square of the magnetic field over the volume. So the magnetic field is known, I integrate over the volume and say that's one-half Li square and then I get the coefficient tells me what L is. Turns out it's proportional to the length of the line. So…

…that there's an emf in the single coil, which is equal to the inductance constant times the current in the single coil. E equals Li dot. And this is what we call, this is in a certain sense an analog of inertia, of electrical inertia in a circuit. You…

…of work, or the energy content of the coil, in getting its current built up from zero to Current I is the integral of Li di I. L is a constant, supposing the coil is fixed. And this is Li square when you integrate, because if you differentiate back,…

…from zero to Current I is the integral of Li di I. L is a constant, supposing the coil is fixed. And this is Li square when you integrate, because if you differentiate back, it checks. So that the energy content of a coil, electrical coil, is 1 half…

…when you integrate, because if you differentiate back, it checks. So that the energy content of a coil, electrical coil, is 1 half Li square. I must... remark, but I left myself not enough time, so I'll leave it to you to figure out because it's just…

…And the suspicion gradually grew that possibly the deep law of the reflection symmetry in nature may be false. And so Li and Yang suggested that other experiments be done in related phenomena, related decays, to try to demonstrate that the law, whether…

…I was scared to ask for myself. But that was the first time that it was publicly suggested in a serious way. And then Li and Yang took it even more seriously and proposed various experiments to try, two among others, which were tried by one by Wu that…

…it's supposed to be small. Now we'd like to find out how much is the voltage fluctuating here. Answer. We know that 1 half Li square is the energy associated with a coil in a resonant circuit. Therefore, the mean value of this thing is equal to 1 half…

…the voltages all over the place from the mean squared current. Example, if you want the voltage across the inductance, the formula is Li omega i. And the mean square of this, that mean absolute square is that. If this is the voltage on the inductance,…

…is equal to L squared, omega naught squared, I squared. And then putting in mean I squared, mean current squared, and putting in for Li squared kT, we obtain L omega zero squared kT. So you too can design circuits and tell when you're going to get what…

…the particles together and call it the total torque. then this will be the rate of change of the sum of all the particles, Li. And that defines a new thing, which we'll call total L, or just L, the total angular momentum. We know about total momentum…

…puzzles. I won't go into detail. We got into tighter and tighter difficulties, more and more paradoxical situation until somebody proposed, Li and Yang proposed, maybe the principle that right and left symmetry, that nature is the same for right and left,…

…that nature is the same for right and left, is not right. And that would help to explain a number of mysteries. And Li and Yang proposed some more direct experiments to demonstrate this. And I'll just mention the most direct of all the experiments, the…
