Inconceivable nature of nature.
理查德·菲利普斯·费曼(英語: Richard Phillips Feynman ,1918年5月11日-1988年2月15日),美国 理论物理学家,以对量子力学的路径积分表述、量子电动力学、过冷液氦的超流性以及粒子物理学中 部分子模型 ( 英语 : parton model ) 的研究闻名于世。
Superfluids in astrophysics. The idea that superfluidity exists inside neutron stars was first proposed by Arkady Migdal. By analogy with electrons inside superconductors forming Cooper pairs because of electron-lattice interaction, it is expected that nucleons in a neutron star at sufficiently high density and low temperature can also form Cooper pairs because of the long-range attractive ...
The complete method was developed in 1948 by Richard Feynman. Some preliminaries were worked out earlier in his doctoral work under the supervision of John Archibald Wheeler . The original motivation stemmed from the desire to obtain a quantum-mechanical formulation for the Wheeler–Feynman absorber theory using a Lagrangian (rather than a Hamiltonian ) as a starting point.
