Hace 5 días · Zero-point energy (ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. Therefore, even at absolute zero, atoms and molecules retain some vibrational motion.
Hace 4 días · By applying a strong electric current via dark energy to the fictional Element Zero or "eezo", "mass effect" fields could be created and manipulated: a positive current raises the mass of any object currently occupying that spot and help to create artificial gravity effects, while a negative current does the inverse by reducing mass ...
Hace 5 días · Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.

Hace 4 días · Zero Defect Plan, also known as the zero-defect program, is an organizational philosophy that aims to reduce the number of defects in new products or processes. In other words, this is a commitment from the company to its customers that all goods will reach them without defects or “defectives.”.
Hace 1 día · View PDF View EPUB. The COVID-19 pandemic had an exceptionally long and consequential rally effect in China. Drawing on an eight-wave nationwide survey, this article shows that the Wuhan lockdown boosted public confidence in the central government. The persistence of the pandemic and the initial success of the zero-COVID policy sustained the ...
