Robert Boyle Robert Boyle. The following are some of the more important of his works: Among his religious and philosophical writings were: Robert Boyle Robert Boyle (; 25 January 1627 – 31 December 1691) was an Anglo-Irish natural philosopher, chemist, physicist, and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a
Electron degeneracy pressure "E" is the total energy of the ensemble. Specifically for the electron degeneracy pressure, is substituted by the electron mass and the Fermi momentum is obtained from the Fermi energy, so the electron degeneracy pressure is given by where is the free electron density (the number of free electrons per unit volume). For the case of a metal, one can prove that this equation remains approximately true for temperatures lower than the Fermi temperature, about kelvin. When particle energies reach relativistic levels, a modified formula is required. The relativistic degeneracy pressure is proportional to . For the case of electrons
