IN the course of electron diffraction investigations, it is often necessary to have a more accurate method of measuring voltage than the spark gap affords. Reference films have been used by several ...

THE variation with pressure of the dielectric constant of the alkali halides has been measured, for selected salts, by Mayburg 1 and Jarman 2, whose work is summarized in Table 1. Jarman deduced that ...

New SOC (system-on-chip) process technology brings with it some process, voltage, and temperature effects, as well as IR drop, which all impact timing closure. Designers can model the on-chip ...

The equilibrium constant for this reaction, referred to as the acid dissociation constant, K a, is expressed in Equation 2.

The long-standing problem of the cosmological constant, described both as “the worst prediction in the history of physics” and by Einstein as his “biggest blunder”, is being tackled with renewed ...

The Hubble constant is one of the most important numbers in cosmology because it tells us how fast the universe is expanding, which can be used to determine the age of the universe and its history. It ...
