Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

Judith Merril, James Blish, and Damon Knight founded the Milford Writer's Conference in 1956. [2] It is both a residential workshop and a writers' conference in which published science fiction writers convene over the course of a week to intensively critique stories and samples from novels (usually works in progress) and to workshop ideas on all aspects of SF writing.
The units of atmospheric pressure commonly used in meteorology were formerly the bar (100,000 Pa), which is close to the average air pressure on Earth, and the millibar. Since the introduction of SI units, meteorologists generally measure atmospheric pressure in hectopascals (hPa), equal to 100 pascals or 1 millibar.
Life, the Universe, & Everything: The Marion K. "Doc" Smith Symposium on Science Fiction and Fantasy is an academic conference held annually since 1983 in Provo, Utah.It is the longest-running science fiction and fantasy convention in Utah, [1] and one of the largest and longest-running academic science fiction conferences.

Comparison of a graph of International Standard Atmosphere temperature and pressure and approximate altitudes of various objects and successful stratospheric jumps The International Standard Atmosphere ( ISA ) is a static atmospheric model of how the pressure , temperature , density , and viscosity of the Earth's atmosphere change over a wide ...
In science and engineering the study of high pressure examines its effects on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure. High pressure usually means pressures of thousands (kilo bars ) or millions (megabars) of times atmospheric pressure (about 1 bar or 100,000 Pa).
WisCon or Wiscon, a Wisconsin science fiction convention, is the oldest, and often called the world's leading, feminist science fiction convention and conference. It was first held in Madison, Wisconsin, in February 1977, [1] after a group of fans attending the 1976 34th World Science Fiction Convention in Kansas City was inspired to organize a convention like WorldCon but with feminism as the ...
