THE successful manner in which the single-particle model of the atomic nucleus has accounted for many nuclear properties is well known to those who follow developments in nuclear physics. This model, ...

Part of Operation Upshot-Knothole, was a 15-kiloton test fired from a 280-mm cannon on May 25, 1953 at the Nevada Proving Grounds. 72 years ago the U.S. Army carried out its first and only nuclear ...

From atomic clocks to secure communication to quantum computers: these developments are based on the increasingly better control of the quantum behaviour of electrons in atomic shells with the help of ...

How big is an atomic bomb? It took a B-29 to carry the first one, dropped on Hiroshima, which may have weighed more than 10,000 Ibs. The Army’s announcement last week that it will abandon its ...

Key Point: The Soviets lost interest in launching nuclear weapons from tanks, but their usefulness has not disappeared. In the 1950s and 1960s when tactical nuclear weapons were expected to rule the ...

A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian University of Munich (LMU), and Johannes Gutenberg University Mainz (JGU) has succeeded in exciting the atomic ...

In Exercise Long Horn, the vast Army-Air Force mock war in Texas, the green-clad Aggressor forces had just seized a position deep behind the defenders’ lines and were massing for a new attack.

Extensive US nuclear testing in the middle of the last century yields a new tool for scientists to use today in dating endangered sea turtles. Freelancer Michael Franco writes about the serious and ...

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and ...
