If you* read his "Six Easy Pieces" (which you can read in a short afternoon -- and* for 1961 physics, not too bad), he uses analogy and descriptions and* illustrations to take the place of the mathematics. There's also a fantastic lecture he have in 1979 in New Zealand which is* available online where he tries his darn'dest to explain QED to regular* folks. (not even college students, per se - a lot of the audience* apparently were NEWSPAPER REPORTERS!) It was a series of four weekly* lectures and while he is explaining QED in terms of particles,* nevertheless, it shows how a very difficult to understand concept CAN be* explained, if given enough time and some good analogies plus a little* teaching of "shorthand" (and feynmann diagrams are pretty simple to grasp* once explained). As a physics enthusiast, I want to know how the world works, what lies* underneath it all, whether the descriptive text is words, equations or* algorythms, analogies, metaphors, pictures, movies or animations, musical* compositions, or even parables. ("Once there was a boy named Tyler. Tyler* was a ripple....") According to Gardener, there are at least 7 styles of learning. Visual,* Acoustic, Kinetic, Introspective, Interspective, and a couple more that I* can't remember right now. But the gist of it is: If you are teaching, you* have to use a variety of teaching methods in order to get your points* across. (or should I say, "get your standing waves across?" Not "points"!) The process of developing a learning program can go in many directions at* once. For example: Someone who is familiar with explaining things to* physicists, in terms that physicists should understand, should begin by* explaining things to physicists in terms that physicists should understand. Another who is good at taking complex concepts and explaining them in* analogies or in word pictures, should do so, perhaps taking what was* intended for the physicist audience and writing word pictures, stories,* analogies, metaphors, parables. Another who is good at computer animations could take the equations and* render them graphically, but can also animate the stories being used for* explanations, assisting both efforts at once. The direction can go from simple --> complex AND from complex ---> simple* AT THE SAME TIME. For example, when I think of WSM, I think of ripples in a pond. It* doesn't matter whether it was rocks thrown in the pond that caused the* ripples, or whether there is 'something' unseeable in the pond which is* causing particular ripples at a particular spot. Either way, there are* ripples. In this pond, there are multitudes of ripples of different sizes and* frequencies. Each of the ripples interact slightly with the others but in general, most* ripples seem to do their ripplings almost independently of each other,* only really touching on the fringes. But, at the fringes of the waves, where waves are touching, they reinforce* each other, interacting in such a way that waves are not only traveling* out from the center of the ripple, but also travelling from the fringe of* the ripple back inwards towards the center of the ripple (making it a* standing wave). But there are more than just ripples on the surface of the pond that you* can see! There are much larger ripples that are barely noticable. These ripples* that come from deep within the pond itself cause the little ripples on the* surface to move with the big ripple, almost unnoticable -- yet it affects* all other ripples on top. Yet this pond does not exist in isolation of the rest of all things. The* pond ITSELF is moving at a rate of speed, so much so that all of the* ripples in the pond are affected not just by the undulations from deep* within the pond, or from their own ripplings, or each others ripplings,* but also from ripples created from the velocity of motion of the entire* pond! These particular ripples are akin to the sound waves heard when a* train is coming towards you (higher pitch) and then passes you (much lower* pitch) - the doppler effect. And THIS pond that is moving at a rate of speed is also interacting with* OTHER ponds that are moving right along side it, in front of it, on top of* it, at the bottom of it, all acting somewhat independently of each other,* yet still somewhat influencing each other. I suppose you could call them.... ahem (::; clearing throat :::) ....* "Space Ponds". It's a horrible analogy perhaps, but it's the closest word picture I can* paint off the top of my head to describe how I mentally envision WSM at* this point in time. (rather, "at this standing wave in time")
