A hundred years of physics tells us that collective atomic vibrations, called phonons, can behave like particles or waves. When they hit an interface between two materials, they can bounce off like a ...

Researchers have used equipment originally intended for astronomy observation to capture transformations in the nuclear structure of atomic nuclei, reports a new study. A group of researchers have ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...

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 ...
