Hace 2 días · Niels Henrik David Bohr ( Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
Hace 4 días · In this article, I reconstruct an argument from Niels Bohr’s writings that the reality of the Einstein-Planck-de Broglie relations alone implies that no such properties can exist for momentum and position measurements, show how this argument responds to the challenge of EPR on general physical grounds, and advance that this reconstruction shows that and how Bohr’s “complementarity” is ...
Hace 2 días · The Niels Bohr Library and Archives has an example of such a book, printed in Germany in 1614, over a century before Jebb’s edition! This book contains the fifth part of Roger Bacon’s Opus Majus , known as Perspectiva (Latin for “Optics”), and is illustrated with figures throughout.

Hans Bethe (1906-2005): Lideró la División Teórica en Los Alamos y fue instrumental en los cálculos de diseño de las bombas. Leo Szilard (1898-1964): Junto con Fermi, demostró la viabilidad de una reacción en cadena nuclear.
Hace 1 día · But instead of the contraction culminating into a bright supernova explosion that would outshine its own galaxy, expected for stars more than eight times as massive as the Sun, the collapse continues until the star becomes a black hole," explains first author Alejandro Vigna-Gómez, who was a postdoc at the Niels Bohr Institute when this study set in motion.
Hace 1 día · New research by astrophysicists at the University of Copenhagen's Niels Bohr Institute presents the strongest evidence to date that very massive stars can succumb with far more stealth and ...
Hace 2 días · To address this, researchers at the Danish Research Center for Magnetic Resonance (DRCMR) and the Niels Bohr Institute at the University of Copenhagen have developed a quantum optical magnetometer. This sensor measures high magnetic fields and is expected to increase the longevity of MRI scanners while improving their quality and lowering costs.
