Some atomic nuclei are not shaped like rugby balls, as a longstanding theory suggests, but are instead somewhat flattened, like almonds, according to a new study by Japanese scientists. A team from ...

THE theory of atomic structure has, during the past few years, reached a stage of sufficient success and stability for it to be possible to describe many of its features in a simple manner. There is a ...

Students use the terms isotope, atomic number, mass number, and atomic mass. Atomic Theory: Structure of the Atom: Students use the terms isotope, atomic number, mass number, and atomic mass to ...

Many heavy atomic nuclei are shaped more or less like squashed rugby balls than fully inflated ones, according to a theoretical study by RIKEN nuclear physicists published in The European Physical ...

The present writer has briefly discussed the history of this law, in NATURE, vol. 1. 1894, p. 149. In two unappreciative lines in a footnote to the “Elements of Chemical Philosophy,” published in 1812 ...

Editor’s Note: Professor WERNER HEISENBERG, who was born in Duisburg in 1901, was awarded the Nobel Prize in Physics in 1932 for his work on the quantum theory. A member of the faculty of the ...

Every field of science has its favorite anniversary. For physics, it’s Newton’s Principia of 1687, the book that introduced the laws of motion and gravity. Biology celebrates Darwin’s On the Origin of ...
