A Time to Kilo: The Quantum Bookie

A Time to Kilo: The Quantum Bookie

In “A Time to Kilo”, BSR writer Anna Lieb describes how new technology is being used to redefine the kilogram in terms of fundamental physical constants. One method being used relies on being able to measure a phenomenon called interference. The simulation below shows how interference is used to calculate the probability of a particle ending up at a particular location. Move the slider to change the frequency of the clocks (how fast they spin). Press “Start” to begin the animation, and “Reset” if you would like to try again. An explanation of each step is shown in the gray box below the animation.
