Definition

Proper noun A German theoretical physicist who originated quantum theory, revolutionizing physics. He discovered that energy is emitted and absorbed in discrete units called "quanta," which laid the foundation for quantum mechanics. He received the Nobel Prize in Physics in 1918 for this work.

Usage

Max Planck is used as a proper noun to refer to the historical figure, his scientific contributions, or institutions named in his honor. - The constant he introduced is known as Planck's constant. - He is considered the father of quantum theory.

Examples
  • Referring to the person:
    • Max Planck was awarded the Nobel Prize for his discovery of energy quanta.

    • Planck's law describes the electromagnetic radiation emitted by a black body.
Advanced Usage
  • "Planck epoch": In cosmology, the earliest period of time in the history of the universe, up to approximately 10⁻⁴³ seconds after the Big Bang.
  • "Planck units": A set of natural units defined using fundamental physical constants, including the Planck constant.
