Video: The Casimir Effect > Zero Point Energy

Notes With Video In a guest lecture at the University of Waterloo's Institute for Quantum Computing, Dr. Peter Milonni of the Los Alamos National Laboratory explains Casimir effects. Casimir effects are generally regarded as manifestations of zero-point energies of quantum fields. The best-known Casimir effects are those associated with the electromagnetic vacuum field; these are of great current interest not only for basic physics but also for their implications for nanotechnology. Following a brief review of the concept of zero-point energy, and experimental evidence for it, attention is be focused on the most famous Casimir effect—the force between two perfectly conducting Read more…

Exponential Function

The following are two different views of the same thing. Constant probability in a given interval of time = an exponential function Constant rate of growth = an exponential function. Now given a fluctuating currency market where a steady 5% is charged to exchange money how much does the Casa do Cambio make?   A simple model would have a fixed exchange rate at 1:1.  Starting with 1000 USD and charging 5% how does the money grow with 1 transaction per day? 1000 1050 1102.50 1157.625 1215.50 1276.28 1340.09 1407.10 1477.55 1551,33
