Electrostatic and magnetostatic phenomena have been familiar to men since antiquity, though until recent times they have been matters of complete mystery. Knowledge of electrical current is relatively new because naturally occurring currents are usually either too small to detect or too rapid (as in lightning flashes) to study.

At high supersonic flight speed, gas heating within the bow wave gives rise to such physical and chemical processes as excitation of the internal energy of the molecules, dissociation, chemical reactions, ionization, and radiation. Intensive aerodynamic heating of the vehicle often results in destruction of the heat protection material.

Environmental and Chemical Effects
2003Abstract This article discusses the chemical susceptibility of a polymeric material. The discussion covers significant absorption and transportation of an environmental reagent by the polymer; the chemical susceptibility of additives; and thermal degradation, thermal oxidative degradation, photo-oxidative degradation, environmental ...
