Exciting Project

A third editor responded to my proposed magnetometer today -- which has been on store shelves in Australia now for two weeks. He wrote: "I find the project very exciting," and noted that it "can even be turned into a saleable product". Alas, too late. I thought that that submission had vanished in the aether. There wasn't a receipt. OBSERVATION: It is a "deeply analogue design", notes the editor, which would require testing in the lab. That makes good sense. Digital or modular designs may merely be a matter of logic, while analogue designs may be more or less impenetrable to logic, and beyond the powers of the best of simulators. That in itself is interesting -- that fairly simple science may befuddle the best minds and computers.
