Heavy water is a form of water with a unique atomic structure and properties coveted for the production of nuclear power and weapons. Like ordinary water—H 2 0—each molecule of heavy water ...

A model showing how metallic bonds are formed - the first diagram shows the outer electrons in their atoms, and the second diagram shows that the electrons have become delocalised ...

One of the largest solar storms in recent history was the 1859 Carrington Event, which released roughly the same energy as 10 billion 1-megaton atomic bombs. After slamming into Earth, the ...

That new language is the language of atomic warfare. The atomic age has moved forward at such a pace that every citizen of the world should have some comprehension, at least in comparative terms, of ...
