ahahah oh my god
NO Einstein is not the father of modern physics . what would mean modern physics by the way
I prefer Landau. Since he was working geniously on much more fields . His books are a reference in studies
Einstein worked in relativity .. the theory was not created by Einstein. there were many theories for explanation of an experiment and he was in the group of one theory. But he was the one to publish first and explain it very well.
In the same time he didn't believe in quantum physics theories : "god doesn't play dice" . he didn't like the genious theory that you cannot determine a movment if you measure it, and that a particle path cannot be predicted for sure but it is all about statistics
Modern physics is not physics of one man. they are a lot of genious who contributed .
And nano tech is not a consequence of his work at all . It is from quantum mechanics .
