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 ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat. Now a series of experiments at atomic and electronic scales is revealing ...

Delve into the detail of atomic physics. As the basic units of matter, atoms are the building blocks for everything in the universe. Once thought to be indivisible, we now know they can indeed be ...
