A nearly 400 year-old formula for pi has been spotted in a quantum-mechanics formula for the energy states of the hydrogen atom, according to researchers in the US. Derived by English mathematician ...

The Bohr Model of Hydrogen revolutionized our understanding of atomic structure and behavior. In this video, we simplify the calculations of force and velocity within the hydrogen atom using Bohr’s ...

Bohr’s atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a much ...

The Bohr atom is unquestionably a landmark in the history of physics. A century after its publication, it has inspired a remarkably diverse and ever-growing field of research. But to fully grasp the ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science ...

Born in 1885 to Christian Bohr – a professor of physiology – and Ellen Adler Bohr in Copenhagen, Denmark, Niels Bohr made numerous contributions to the field of physics over the course of his life, up ...

The Danish physicist and Nobel laureate Aage Niels Bohr died on 8 September at the age of 87. The son of quantum-physics pioneer Niels Bohr, Aage himself made critical contributions to the structure ...

The quantum world is notoriously difficult to comprehend. As Niels Bohr famously stated, “Anyone who is not shocked by quantum theory has not understood it.” One of the things we pride ourselves on ...

Quantum physics might not be the most approachable topic, but there’s a good chance you’ve heard of some of its elemental parts, like atoms. In the early 20th century, Danish physicist Niels Bohr ...

John L. Heilbron describes the route that led Niels Bohr to quantize electron orbits a century ago. You have full access to this article via your institution ...
