John Dalton, First Useful Atomic Theory; ... Max Planck, Inventor of Quantum Theory; Max Karl Ernst Ludwig Planck was a German physicist who is considered to be the inventor of quantum theory. In 1899, he discovered a new fundamental constant, which is named Planck's constant, and is, for example, used to calculate the...

Proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass. ... Using alpha particles as atomic bullets, probed the atoms in a piece of thin (0.00006 cm) gold foil . He established that the nucleus was: very dense,very small and positively charged. He also assumed that the electrons...

Two names clearly stand out: Max Planck (1858-1947) and Werner Heisenberg (1901-1976). Planck is recognised as the originator of the quantum theory, while Heisenberg formulated one of the most eminent laws of quantum theory, the Uncertainty Principle, ... Elements are distinguished by their "atomic number",

Both these relationships were synthesized by physicist Max Planck into what is called Planck's curve. All objects emit energy in the shape of Planck's curve, where the amount and the peak energy vary only as the temperature of the body. ... Planck's solution, while fitting the data, produces a contradiction for atomic theory...

The German physicist Max Karl Ernst Ludwig Planck, b. Apr. 23, 1858, d. Oct. 3, 1947, developed the concept of the quantum, or fundamental increment of energy--basic to Quantum Mechanics, and a cornerstone of modern physics. ... The quantum theory--which gained Planck the Nobel Prize for physics in 1918- ... Exit Atomic Magic...

; Arranged elements into 7 groups with similar properties. He discovered that the properties of elements "were periodic functions of the their atomic weights". This became known as the Periodic Law. ... ; Proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass.

This theory revolutionized our understanding of atomic and subatomic processes, ... By the end of the war, Planck, his second wife and his son by her, moved to Göttingen where he died on October 4, 1947. Max Planck made brilliant discoveries in Physics which revolutionized the way we think about atomic and subatomic processes.
