According to his recollections, as he listened in horror to the reports from Japan, Heisenberg felt devastated....One week later, Heisenberg lectured to his colleagues and explained to them exactly how the bombs over Hiroshima and Nagasaki had worked….

In 1941 “Heisenberg traveled to occupied Denmark and met in private with Niels Bohr.Their respective accounts of that conversation differ significantly…Did Heisenberg go…to learn something about the Allies' intentions and potential progress with…an atomic weapon….
…the laws of physics…are really the laws of our observations of how things behave. Or, as Heisenberg would later say, "we have to remember that what we observe is not nature in itself but nature exposed to our method of questioning."

“As Bohr explained…no one could take seriously anymore the image of electrons orbiting a nucleus like planets...”

“…Hantaro Nagaoka, had postulated in 1903 a "Saturnian" model of the atom with flat rings of electrons…”

…no information actually travels between two entangled particles when one is observed.What happens,rather,is that one observer now has a knowledge of what some other observer will see if they observe the particle somewhere else.

…Heisenberg drew his famous comparison to Einstein's own work, pointing out that the revolutionary insight that enabled his relativity theory occurred when Einstein decided to disregard what everyone thought they knew about space and time….

Einstein's theories of special and general relativity explain to a remarkable degree of accuracy the workings of the universe…Quantum mechanics, for its part, has proven uncontested in its ability to probe the smallest constituents of matter….

Heisenberg's principle shows that the closer you home in on the location of a particle, the less you know about its momentum…Or, conversely, you can find out a great deal about its momentum, but to do so, you lose all sense of where it is.

“…in 1913, Bohr had demonstrated that inside the atom electrons…occupied distinct orbits around the nucleus and appeared to ‘jump’ from one to the other….electrons show up in their new orbit without seeming to have traveled in between.”
“…he knew that his ability to see himself clearly…had…been corrupted by his attempts to bring her into focus.”

The closer we look, the more the present vanishes from our grasp…the insight that hit Werner Heisenberg in Copenhagen….

It wasn't merely that the physicist isn't able to see a particle's position and momentum at the same time; astoundingly, the particle doesn't have a momentum and a position in any meaningful sense until the physicist decides to measure one or the other.
