Complementarity A principle proposed by Bohr in the mid-1920s, which argues that some pairs of physical properties, e.g. position and momentum of a particle, cannot be measured simultaneously ...
Jim Baggott is a science writer based in Cape Town, South Africa. He is co-author with John Heilbron of Quantum Drama. Quantum mechanics is an extraordinarily successful scientific theory, on which ...
Another Solvay Conference was scheduled for late in October 1927. Einstein had told Lorentz he never wanted to be invited again, and the French and Belgians still despised Germans, but the conference ...
Scientists are like prospectors, excavating the natural world seeking gems of knowledge about physical reality. And in the century just past, scientists have dug deep enough to discover that reality’s ...
The seeds of quantum theory were sown by Albert Einstein and others as early as 1905. But the theory came together properly 100 years ago in 1925 – and has exerted its influence ever since, as this ...
Niels Bohr seems to have won a battle over Albert Einstein, according to a study published in the journal Physical Review Letters. This debate was regarding the quantum mechanical principle of ...
So darkly complex, so fabulously remote from the familiar things of human existence is science’s probing into the fundamental secretae of the universe—of light, electricity, gravity, matter—that the ...
Scientists are like prospectors, excavating the natural world seeking gems of knowledge about physical reality. And in the century just past, scientists have dug deep enough to discover that reality’s ...
As one of the original architects of quantum theory, perhaps our most successful scientific idea, you would think that Niels Bohr would have been interested in the nature of reality. The subjects of ...
On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...
Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...
