Gravity To Electricity Everything Inbetween

With all our knowledge of science and technology on how the world around us works and what incredible new inventions are coming on stream all the time, it’s hard to imagine how life was back a couple of centuries.  We had the greatest minds beavering away – developing electricity . . .  that breakthrough must have seemed so incredible.  Something we take for granted every hour of the day.   Einstein was one of the most famous men ever – very few will eclipse him.  A universit in the US is publishing all his letters and papers – hundreds of items show nuances about his genious and downsides to that huge personality.   Some highlight his despair at the lack of progress towards the unified theory of gravity and electricity – one of his major goals.   So many other inventions came along to distract work – take quantum ideas describing mechanics of electrons and subatomic particles and that was back in the 1920s & ’30s.  Todays scientific world take every new challenge and runs with it quicker and more confidently!
