Einstein's Clocks and Thought Experiments


 Einstein's Clocks 

 OR 
 A Flight Of Imagination  
 That Revealed The Real World
 In 1905 

 About Einstein's thought experiments
 and his ability to imagine in the moment

 Late one night 
 after struggling with the physics of light, 
 Albert heard the distinctive ring 
 of Bern's Zytglogge clock tower, 
 with its 500 year-old bell 
 struck by a figure 
 representing Chronos, the Greek god of time. 

 In a flash 
 he was riding a streetcar 
 at the speed of light 
 and looking back at the time 
 on the Bern clock 
 which froze 
 because the light from its later time 
 could never catch him. 
 Yet he could see the minutes 
 on his pocket watch were 
 continuing. 

 And then he knew 
 time was relative.

The man who arrives at the doors of artistic creation with none of the madness of the Muses would be convinced that technical ability alone was enough to make an artist... what that man creates by means of reason will pale before the art of inspired beings.
Plato

There comes a point where the mind takes a leap 
— call it intuition or what you will — 
and comes out upon a higher plane of knowledge, 
but can never prove how it got there. 
All great discoveries have involved such a leap.
Albert Einstein
