**Fact 1**

Max Planck was born on April 23, 1858 and died on October 4, 1947.**Fact 2**

Planck made many contributions to theoretical physics, but his popular reputation is chiefly because of his discoverer of the quantum theory.**Fact 3**

Planck was amid the few who instantly recognized the importance of the special theory of relativity and he also contributed considerably to extend this theory.

In 1918Planck was also given the Nobel Prize in Physics.

Planck got honorary doctorates from the universities of Frankfurt, Rostock, Athens, Cambridge, Berlin (TH), Graz, London, Munich (TH), and Glasgow.

The asteroid 1069 was named after him as "Stella Planckia" by the International Astronomical Union in 1938.

Based on the concept that energy produced by a resonator could only take on separate values or quanta, he deduced that the energy for a resonator of frequency ‘v’ is ‘hv’ where ‘h’ is a universal constant, now named Planck’s constant.

The finding of Planck’s constant allowed him to outline a new universal set of physical units like the Planck length and the Planck mass that were all based on fundamental physical constants.

Planck’s work on the quantum theory was published in the Annalen der Physik and his work is summarized in 2 books Thermodynamik (Thermodynamics) and Theorie der Wärmestrahlung (Theory of heat radiation).

In 1905, the 3 epochal papers of Albert Einstein were published in the journal Annalen der Physik and Planck was amongst the few who instantly acknowledged the importance of the special theory of relativity.
