The Bohr atom is unquestionably a landmark in the history of physics. A century after its publication, it has inspired a remarkably diverse and ever-growing field of research. But to fully grasp the ...

For millennia, atoms had been phantoms, widely suspected to exist but remaining stubbornly invisible — though not indivisible, as their name (Greek for “uncuttable”) originally implied. By the start ...

HOUSTON -- June 30, 2008 -- Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, ...
