1957: Stokes nuclear weapon test conducted by the United States.
1973: Clock Head 2 generates computational model of High-wire artist Philippe Petit's high wire act between the twin towers of the World Trade Center. A year later, Petit will use this model to improve his balance during the actual walk.
1974: High-wire artist Philippe Petit performs a high wire act between the twin towers of the World Trade Center.
