In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
(The Big Crunch was a leading theory of the fate of the universe at the time this book was written.) The universe collapses (a process the starship survives because there is still enough uncondensed hydrogen for maneuvering outside the growing singularity) and then explodes in a new Big Bang. The voyagers then decelerate and finally disembark ...
Dihydrogen monoxide is a name for the water molecule, which comprises two hydrogen atoms and one oxygen atom (H 2 O).. The dihydrogen monoxide parody is a parody that involves referring to water by its unfamiliar chemical systematic name "dihydrogen monoxide" (DHMO, or the chemical formula H 2 O) and describing some properties of water in a particularly concerning manner — such as the ...
The list includes technologies that were first posited in non-fiction works before their appearance in science fiction and subsequent invention, such as ion thruster. To avoid repetitions, the list excludes film adaptations of prior literature containing the same predictions, such as " The Minority Report ".
Hydrogen sulfide is a chemical analog of water, but is less polar and a weaker inorganic solvent. [citation needed] Methane biochemistry (Azotosome) Non-water solvents Methane-based life Methane is relatively abundant in the Solar System and the Universe, and is known to exist in liquid form on Titan, the largest moon of Saturn. Though highly ...
Hyperion is a 1989 science fiction novel by American author Dan Simmons. The first book of his Hyperion Cantos series, it won the Hugo Award for best novel. [1] The plot of the novel features multiple time-lines and is told from the point of view of many characters. It follows a similar structure to The Canterbury Tales by Geoffrey Chaucer.
A chaotropic agent is a molecule in water solution that can disrupt the hydrogen bonding network between water molecules (i.e. exerts chaotropic activity).This has an effect on the stability of the native state of other molecules in the solution, mainly macromolecules (proteins, nucleic acids) by weakening the hydrophobic effect.
The Legacy of Heorot is a science fiction novel by American writers Larry Niven, Jerry Pournelle, and Steven Barnes, first published in 1987. [1] Reproduction and fertility expert Dr Jack Cohen acted as a consultant on the book, designing the novel life cycle of the alien antagonists, the grendels. [2] This is the first book in the Heorot series.
