Oxyliquit explosive was prepared ad hoc from sugar and liquid oxygen from an oxygen bottle to blast a hole in a collapsed cave in Stanisław Lem's 1951 novel The Astronauts. The same device was used in Andy Weir's novel The Martian and the movie adaptation to cause the intentional depressurization of a spaceship by blasting the airlock door.
In the fictional history of the world by J. R. R. Tolkien, Moria, also named Khazad-dûm, is an ancient subterranean complex in Middle-earth, comprising a vast labyrinthine network of tunnels, chambers, mines, and halls under the Misty Mountains, with doors on both the western and the eastern sides of the mountain range.
Orientation had become too difficult. Fankhauser and Schlick began to search for him that evening, but lost their way and sought shelter at first in a snow cave. Messner himself was no longer in a position to help the search. The following day, only Horst Fankhauser returned. Andi Schlick had left the snow cave during the night and disappeared.
Dark oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis.The name therefore uses a different sense of 'dark' than that used in the phrase "biological dark matter" (for example) which indicates obscurity to scientific assessment rather than the photometric meaning.
Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O 2 , like liquid oxygen , is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
Calypso's Cave (Maltese: L-Għar ta' Calisso) is a natural cave, located on the western side of the Ramla bay, in Xagħra, Gozo. [1] The cave is alleged to be the one referenced in the Odyssey as the cave where the nymph Calypso kept Odysseus prisoner for seven years after his ship was wrecked after a fierce storm.
Oxygen (δ 18 O) and carbon (δ 13 C) stable isotopes are used to track variation in rainfall temperature, precipitation, and vegetation changes over the past ~500,000 years. [6] [7] The Mg/Ca proxy has likewise been used as a moisture indicator, although its reliability as a palaeohygrometer can be affected by cave ventilation during dry ...
