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 ...

Niels Bohr's atomic model was utterly revolutionary when it was presented in 1913. Although it is still taught in schools, it became obsolete decades ago. However, its creator also developed a much ...
