__ **Experiments** __
 * One early experiment was when he attended Foxhill School. He used the speed of sound to determine the distance to a firing cannon. This helped him estimating the distance to the lightning flash.
 * He developed two devices; a simple mechanism for switching two electrical circuits with a time interval between them.
 * Also a magnetic detector of very fast current pulses.
 * In Rutherford’s Gold Foil Experiment, he discovered the ATOMIC NUCLEUS.[|click here to see a tutorial]



In this experiment, a beam of positively charged particles were sent through a sheet of thin gold foil. Nearly all the positive charged particles passed through the gold foil with little or no deflection. A few deflected beacuse those went head on with another nucleus. Rutherford reasoned that the undeflected particles traveled through the gold foil that were empty space. He concluded that each atom must have an atomic nucleus.
