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 .

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.
The lung's alveoli are not tiny balloons that expand and contract under positive pressure following the Young–Laplace equation, as is taught in some physiology and medical textbooks. The tissue structure is more like a sponge with polygonal spaces that unfold and fold under negative pressure from the chest wall. [288]

Science fiction poetry's main sources are the sciences and the literary movement of science fiction prose. [9]Scientifically-informed verse, sometimes termed poetry of science, is a branch that has either scientists and their work or scientific phenomena as its primary focus; it may also use scientific jargon as metaphor.

Many of the most enduring science fiction tropes were established in Golden Age literature. Space opera came to prominence with the works of E. E. "Doc" Smith; Isaac Asimov established the canonical Three Laws of Robotics beginning with the 1941 short story "Runaround"; the same period saw the writing of genre classics such as the Asimov's Foundation and Smith's Lensman series.
Steampunk is a subgenre of science fiction, fantasy and speculative fiction that came into prominence in the 1980s and early 1990s. The term denotes works set in an era or world wherein steam power is still widely used—usually the 19th century, and often set in Victorian era England—but with prominent elements of either science fiction or fantasy, such as fictional technological inventions ...
