But their ideas fell short of describing a complete theory. It was the German physicist Werner Heisenberg who, in 1925, first put forward a comprehensive version of quantum mechanics. Later that ...

Chemistry World welcomes letters, which should be concise (normally fewer than 300 words) and timely. Those selected for publication are subject to editing for clarity and length. Letters should be ...

Utilizing Ramsey interferometry, the researchers confirmed that the phase measurement sensitivity approached the Heisenberg limit. This long-lived Schrödinger-cat state paves a new way for atomic ...

R. Soc., including Paul Dirac, Werner Heisenberg, James Clerk Maxwell, Ernest Rutherford, and Erwin Schrödinger. The Proceedings started out in 1800 as the Abstracts of the Papers Printed in the ...

His work gave new insight between the old quantum theory of Planck, Einstein, Bohr and Sommerfeld, and the new quantum mechanics of Heisenberg, Dirac and Schrodinger. In June 1924, the first ...

When an electron dropped from a high-energy orbit to a lower-energy one, it gave out light with an energy equal to the ...

Quantum physics underlies technologies from the laser to the smartphone. The International Year of Quantum marks a century of scientific developments.

Yet, quantum mechanics is far from complete. Despite its success in explaining a wide range of phenomena, questions remain. The nature of dark matter, the integration of gravity into quantum theory, ...
