Generally speaking, the folks in Princeton set up machines all over the world that generate random numbers [in quotes since we're still pushing an understanding beyond what goes on further below the Planck scale but I think we're as random as we're psychologically evolved to gather and dispel heat] they collect and display the data signifying correlations of the data with real world events.
The lock cylinder turns with the key. As it turns it actuates the ignition switch which closes electrical contacts and provides power to gauges, lights, engine and starter. If the key won't turn, chances are the lock cylinder is worn out.
We call them Sleeping Policemen in the UK!! I did read that Col Edgar Rothkrug (US Army) was credited with inventing a type of speed bump in WWII and the bumps were referred to as the Rothkrug bump in Army manuals. But as the city of Chatham in New York first used speed bumps to slow traffic back in 1906 I hardly think the Col. was the original inventor.
