“Two minds with but a single thought… how Newton and Leibniz invented calculus.”

I saw that jokey sentence somewhere but it’s funny only to people who know some history .

I find it very strange that quite frequently people in different parts of the world  invent or discover the same thing more ore less simultaneously………..this was true  long before people could share ideas on the internet.I believe that Charles Darwin’s Evolutionary theory was also invented by someone else and that’s what  pushed Darwin to publish it.Whether it’s true or not it has resulted in some dreadful consequences like Eugenics which was favored by Galton and influenced many minds[  of politicians] in Europe in the late 19th and early 20th Centuries with dreadful results…

Many of our discoveries have more than one face… like nuclear power.And now we need so much power,electrical and other to maintain our civilization such as it is now..Some people think we are nearing the end of this era…and some are bringing it on using post modernist thought which has links to Fascist thinking I read though I have never grasped exactly what it is.
