I've got a couple of superconductivity-related questions: 1. I keep hearing people say you can "cook up liquid N2 temperature superconductors in any microwave" on the news and in some magazines. Is this an oversimplification by the media or is it true? And if true, anybody have a recipe? 2. Can anybody give me any good references on a description of the Meisner effect (probably spelled wrong, I refer to the effect that allows a magnet to levitate over a superconductor). I'm mainly interested in an overview of what kind of magnetic fields are setup and what governs the hight that the magnet floats at. Also I would like to know if anyone can think of a way to cause the floating magnet to spin. Thanks in advance for whatever help I get. Greg Corson

MacNeil/Lehrer did a spot on Superconductors the other day. It wasn't too bad. The production of the material (don't know how much they glossed over) seemed to be mechanical mixing of the products and then placing the thing into a press (sorry no microwaves=N.I
