Max Planck
German physicist (1858–1947)
Max Karl Ernst Ludwig Planck was a German theoretical physicist. Planck made many contributions to theoretical physics, primarily in his role as the originator of quantum theory and one of the founders of modern physics, which revolutionized understanding of atomic and subatomic processes. He is known for the Planck constant, , which is of foundational importance for quantum physics, and which he used to derive a set of units, now called Planck units, expressed in terms of physical constants. The Planck relation, E= ν, states that the energy of a photon is proportional to its frequency.
“Max Planck” enters the record as german physicist (1858–1947). Crown Archives preserves that source wording while asking what Planck, German and physicist can confirm, complicate or overturn.
Why this record matters
“Max Planck” is worth following because a concise public description often conceals a longer documentary argument. Here, Planck, German and physicist provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 12, 2026.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
