Planck Mass
The Planck mass (m_P) is a fundamental physical constant representing a mass scale derived from natural units, approximately 2.176 × 10^-8 kilograms.
History/Origin
Introduced by Max Planck in 1899 as part of his system of natural units, the Planck mass emerged from combining fundamental constants to define a universal mass scale in theoretical physics.
Current Use
The Planck mass is primarily used in theoretical physics, especially in quantum gravity and high-energy physics, to express natural units and scale phenomena near the Planck scale.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
