How great? Enough to lift the Empire State Building? No! To lift Mount Everest? No! The repulsion would be enough to lift a weight equal to that of the entire earth!2- You may ask: If this electrical force is so terrific, why don’t the protons and electrons just get on top of each other? .. The answer has to do with the quantum effects. If we try to confine our electrons in a region that is very close to the protons, then according to the uncertainty principle they must have some mean square momentum which is larger the more we try to confine them. It is this motion that keeps the electrical attraction from bringing the charges any closer together.3- The nuclear forces have a short range, their force falls off much more rapidly than 1/r^2.4- The energy of the atomic bomb is usually called nuclear energy, but it is really “electrical” energy released when electrical forces have overcome the attractive nuclear forces.5- One part of the force between moving charges we call the magnetic force. It is really one aspect of an electrical effect.6- A field is any physical quantity which takes on different values at different points in space.7- the electric field is not the velocity of anything.8- With just these two ideas—flux and circulation, we can describe all the laws of electricity and magnetism at once.9- We define a quantity called circulation .. if there is more momentum heading one way around the tube than the other. We can again extend our ideas and define the circulation for any vector field (even when there isn’t anything moving).10- The attempts to try to represent the electric field as the motion of some kind of gear wheels, or in terms of lines, or of stresses in some kind of material have used up more effort of physicists than it would have taken simply to get the right answers about electrodynamics. It is interesting that the correct equations for the behavior of light were worked out by MacCullagh in 1839. But people said to him: Yes, but there is no real material whose mechanical properties could possibly satisfy those equations, and since light is an oscillation that must vibrate in something, we cannot believe this abstract equation business .. two charges moving in space, both at the same speed and parallel to each other; because they are moving, they will behave like two currents and will have a magnetic field associated with them (like the currents in the wires of Fig. 1–8). An observer who was riding along with the two charges, however, would see both charges as stationary, and would say that there is no magnetic field.11- magnetism is really a relativistic effect .. Now we realize that the phenomena of chemical interaction and, ultimately, of life itself are to be understood in terms of electromagnetism.Chapter 212- Dirac said: I understand what an equation means if I have a way of figuring out the characteristics of its solution without actually solving it. So if we have a way of knowing what should happen in given circumstances without actually solving the equations, then we “understand” the equations, as applied to these circumstances. A physical understanding is a completely unmathematical, imprecise, and inexact thing, but absolutely necessary for a physicist. .13- the subject of physics has been developed over the past 200 years by some very ingenious people, and as we have only a limited time to acquire our knowledge, we cannot possibly cover everything they did.14- The argument that grad T is a vector did not depend upon what scalar field we were differentiating. Feynman proves eloquently the decoupled property of the vector itself from the type (which in this case happens to be temperature) of the scalar field whence it has been derived; Feynman describes the process conducted with the following words: we have abstracted the gradient away from the T.15- operator algebra is a little different from ordinary vector algebra.16- direction of grad T is that in which it has the largest possible component—in other words, the direction in which T changes the fastest.17- The sum is invariant under a coordinate transformation, grad.h = grad.h for every point in space. So grad⋅h is a scalar field, which must represent some physical quantity.18- combinations like ∂hy/∂x are neither scalars nor components of vectors.Notes:For the derivation of The Feynman Lectures on Physics, Volume II, Fig. 2–6 equations.http://scontent-a-ams.xx.fbcdn.net/hp...
