The Planck constant, or Planck's constant, denoted by h {\textstyle h} , is a fundamental physical constant of foundational importance in quantum mechanics:...

In particle physics and physical cosmology, Planck units are a system of units of measurement defined exclusively in terms of four universal physical constants:...

Max Karl Ernst Ludwig Planck ForMemRS (/ˈplæŋk/; German: [maks ˈplaŋk] ; 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery...

The Max Planck Society for the Advancement of Science (German: Max-Planck-Gesellschaft zur Förderung der Wissenschaften e. V.; abbreviated MPG) is a formally...

Kelvin-Planck statements, such is not the case. To get all the content of the second law, Carathéodory's principle needs to be supplemented by Planck's principle...

Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013. It was an ambitious project that aimed to map the anisotropies...

In physics, Planck's law (also Planck radiation law: 1305 ) describes the spectral density of electromagnetic radiation emitted by a black body in thermal...

electromagnetic black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature...

chronology: The first picosecond (10−12 seconds) of cosmic time includes the Planck epoch, during which currently established laws of physics may not have applied;...

In loop quantum gravity theory, a Planck star is a hypothetical astronomical object, theorized as a compact, exotic star, that exists within a black hole's...

The Max Planck Institute for Human Cognitive and Brain Sciences is located in Leipzig, Germany. The institute was founded in 2004 by a merger between the...
