    Imaginary numbers have had a great effect whether direct or indirect on the microwave oven. Although the concept has come out of left field, there is still a plausible explanation for their influence on the microwave oven. The fact remains that complex numbers have much less direct relevance to real-world quantities than other numbers do. An imaginary number could not be used as a measurement of how much water is in a bottle, or how far a kite has traveled, or how many fingers you have. There ar...

    'If I had my life to live over again, I should devote myself to psychical research rather than to psychoanalysis,' wrote Sigmund Freud to associate He reward Carrington. Freud had this late-in-life wish, but alas -- time would not grant its fulfilment. Such testimony by the eminent father of psychoanalysis bears witness to the fact that psychical experiences are indeed central to our lives.

    My project's goal was to make a metal detector that can successfully detect pieces of metal (actually anything conductive) within a range of 15 cm depending on the object's conductivity and its surface area parallel to the plane of the search coil (and I did it! ). My detector is a simple one with almost no discrimination, which means that it will detects metal objects independent of their chemical composition or provides no further information about their properties. There are some specialized ...
