Millikan / Electrão - Measure the electron's charge
    MILLIKAN simulates one of the most important physics experiments of our century: that done by Millikan to determine the electronic charge.
    Many school activities may be done with this simulation, which include, like all our programs, protocols suited to the actual curricula. Here, we may ionise one oil drop by X-rays, switch on and off an electric field, and measure the terminal velocity of the drop with a rule. We have inserted an automatic simulation, which contains typical experimental errors.
