Intractable Problems

Theorists of the 20th century had failed to recognize an underlying law of physics governing the propagation of light: linearly propagating electromagnetic radiation (and neutrinos) is subject to the Principle of velocity differential propagation. The Principle, which is shown to rest on sound physics, has two manifestations: the second of these, the blueshifting of light (and neutrinos) within the internal portion of a gravity well, is explored. The Principle is applied to an end-state neutron star (a stable gravitationally collapsed body). Examined is its energy layer, the energy generation/amplification that takes place there, and the mechanism by which the energy escapes to the external world. Highlighted is the steady-state perpetual nature of the process; and its applicability in solving two of the most intractable problems in astrophysics. The implications for cosmology are profound and incontrovertible.

Abstract Excitation of molecules by incident incoherent electromagnetic radiation, such as sunlight, is described in detail and contrasted with the effect of coherent (e.g. laser) light. The nature of the quantum coherences induced by the former, relevant to transport processes in nature and in technology, is emphasized. Both equilibrium and steady state scenarios are discussed, Three examples: simple models, calcium excitation in polarized light, and the isomerization of retinal in rhodopsin are used to expose the underlying qualitative nature of the established coherences.

Electricity And Magnetism

A review of the basic elements of electricity and magnetism is presented with an introduction to Maxwell’s equations for steady-state in a vacuum. The modifications to these equations necessary to account for time varying sources are shown to produce to a causal unification of magnetic and electric fields. The application of Maxwell’s equations in the presence of matter leads to the concepts of electric and magnetic polarization of matter. Electromagnetic radiation arises directly from Maxwell’s time-dependent equations and the basic response of materials to this radiation is discussed. Finally, electromagnetic conservation laws are derived, including electromagnetic energy and linear and angular momentum.

Differential Pumping

Use of the electron microscope to examine wet objects is possible due to the small mass thickness of the equilibrium pressure of water vapor at room temperature. Previous attempts to examine hydrated biological objects and water itself used a chamber consisting of two small apertures sealed by two thin films. Extensive work in our laboratory showed that such films have an 80% failure rate when wet. Using the principle of differential pumping of the microscope column, we can use open apertures in place of thin film windows.Fig. 1 shows the modified Siemens la specimen chamber with the connections to the water supply and the auxiliary pumping station. A mechanical pump is connected to the vapor supply via a 100μ aperture to maintain steady-state conditions.
