Atomic physics although they could be described and classified by their properties (in bulk). The invention of the periodic system of elements by Mendeleev was another great step forward. The true beginning of atomic physics is marked by the discovery of spectral lines and attempts to describe the phenomenon, most notably by Joseph von Fraunhofer. The study of these lines led to the Bohr atom model and to the birth of quantum mechanics. In seeking to explain atomic spectra an entirely new mathematical model of matter was revealed. As far as atoms and their electron shells were concerned, not only did this
Fantastic Four: Unstable Molecules Fantastic Four: Unstable Molecules Fantastic Four: Unstable Molecules is a four-issue comic book limited series published by Marvel Comics. The series imagines that the creators of the Fantastic Four were inspired by people encountered in their own lives during the late 1950s and provides a backstory for those analogues. Dr. Reed Richards lives in the small town of Glen Cove and works at Columbia University, attempting to discover a practical use for the sub-atomic particles that he has discovered. He is so absorbed in his work that he forgets that he is due to host a cocktail party for his
