1 天前 · Using the theory of Herapath, he derived relationship between heat and kinetic energy in 1851. The next important development was due to John James Waterston in 1851. His work, however, remained unrecognized. The concepts similar to Waterston’s were advanced by Karl Krönig in 1856.
2024年4月25日 · The kinetic theory of gases is now a classical part of statistical physics and is indeed a sort of miniature display case for many of the fundamental concepts and methods of science. Such important modern concepts as distribution functions, cross sections, microscopic reversibility, and time-reversal invariance have their historical ...

21 小時前 · The internal kinetic theory temperature of a body cannot take negative values. The thermodynamic temperature scale, however, is not so constrained. For a body of matter, there can sometimes be conceptually defined, in terms of microscopic degrees of freedom, namely particle spins, a subsystem, with a temperature other than that of the whole body.

2024年4月18日 · Ludwig Boltzmann was a physicist whose greatest achievement was in the development of statistical mechanics, which explains and predicts how the properties of atoms (such as mass, charge, and structure) determine the visible properties of matter (such as viscosity, thermal conductivity, and.

2 天前 · A universal, one-parameter scaling theory is developed that describes transport behavior from the ballistic to the diffusive regime in multimode nonlinear photonic circuits. Figure 3 The ratio of thermal to power conductivity ϰ / σ versus temperature (black dots) for different values of nonlinearities χ = 0, 0.025, 0.05, 0.1, 0.25, 0.5, 0.75, 1.0, and junction sizes N = 150, 300, 600.
21 小時前 · In the present work, the behavior of the gas near the corner is examined based on numerical results obtained from the kinetic theory. Although the range of the flow velocity value in the kinetic solution is limited due to the significant velocity slip near the corner, the flow velocity is, nevertheless, multivalued at the corner.
