A glide reflection is the composition of a reflection across a line and a translation parallel to the line. This footprint trail has glide-reflection symmetry. Applying the glide reflection maps each left footprint into a right footprint and vice versa.
Examples of this trope include Martin Gardner ' s "No-Sided Professor" (1946), Armin Joseph Deutsch ' s "A Subway Named Mobius" (1950) and the film Moebius (1996) based on it. An entire world shaped like a Möbius strip is the setting of Arthur C. Clarke 's "The Wall of Darkness" (1946), while conventional Möbius strips are used as clever ...
Science in science fiction is the study or of how science is portrayed in works of science fiction, including novels, stories, and films. It covers a large range of topics. Hard science fiction is based on engineering or the "hard" sciences (for example, physics, astronomy, or chemistry).
Mirror matter could have been diluted to unobservably low densities during the inflation epoch. Sheldon Glashow has shown that if at some high energy scale particles exist which interact strongly with both ordinary and mirror particles, radiative corrections will lead to a mixing between photons and mirror photons.

Individual left and right footprints are chiral enantiomorphs in a plane because they are mirror images while containing no mirror symmetry individually. In geometry , a figure is chiral (and said to have chirality ) if it is not identical to its mirror image , or, more precisely, if it cannot be mapped to its mirror image by rotations and ...
The Light of Other Days is a 2000 science fiction novel written by Stephen Baxter based on a synopsis by Arthur C. Clarke, [1] which explores the development of wormhole technology to the point where information can be passed instantaneously between points in the spacetime continuum.
The Ambidextrous Universe is a popular science book by Martin Gardner, covering aspects of symmetry and asymmetry in human culture, science and the wider universe.It culminates in a discussion of whether nature's conservation of parity (the symmetry of mirrored quantum systems) is ever violated, which had been proven experimentally in 1956.
"Surface Tension" is a science fiction short story by American writer James Blish, originally published in the August 1952 of Galaxy Science Fiction. As collected in Blish's The Seedling Stars , it was revised to incorporate material from his earlier story "Sunken Universe", published in Super Science Stories in 1942.
