The Holoscope: a cube of mirrors. A type of kaleidoscope based on truncated Platonic solids by artist Gary Allison. This holoscope is in the form of a cube with each corner cut off allowing light to enter through triangular holes. Through the symmetry of the reflections, these triangles appear as an infinite array of stellated octahedrons. Each holoscope has stained glass on the exterior and front surface mirrors on the inside which create the amazing and seemingly impossible spaces within. ➡️ Follow the link in my profile for more info on holoscopes and the artist that makes them, and where to get other amazing items featured here on @physicsfun #kaleidoscope #mirrors #reflection #multiplereflection #geometry #cube #platonicsolid #optics #light #infinity #physics #physicstoy #science #mathtoy #mathstoy #scienceisawesome

The furry scales on air plants are called trichomes. They help to reflect sunlight and collect moisture from the air. They close upon getting wet and re-open after a few hours. The Tillandsia tectorum species is prized for its highly pronounced trichomes. . Geometric planters: @fuxigold - love the chain!

Wormhole: a gateway between two distant part of the universe (or the multiverse) The basic notion of an intra-universe wormhole is that it is a compact region of spacetime whose boundary is topologically trivial but whose interior is not simply connected. Formalizing this idea leads to definitions such as the following, taken from Matt Visser's Lorentzian Wormholes. If a Minkowski spacetime contains a compact region Ω, and if the topology of Ω is of the form Ω ~ R x Σ, where Σ is a three-manifold of nontrivial topology, whose boundary has topology of the form dΣ ~ S2, and if, furthermore, the hypersurfaces Σ are all spacelike, then the region Ω contains a quasi-permanent intra-universe wormhole. Characterizing inter-universe wormholes is more difficult. For example, one can imagine a 'baby' universe connected to its 'parent' by a narrow 'umbilicus'. One might like to regard the umbilicus as the throat of a wormhole, but the spacetime is simply connected. Lorentzian traversable wormholes would allow travel from one part of the universe to another part of that same universe very quickly or would allow travel from one universe to another. The possibility of traversable wormholes in general relativity was first demonstrated by Kip Thorne and his graduate student Mike Morris in a 1988 paper; for this reason, the type of traversable wormhole they proposed, held open by a spherical shell of exotic matter, is referred to as a Morris-Thorne wormhole. Later, other types of traversable wormholes were discovered as allowable solutions to the equations of general relativity, including a variety analyzed in a 1989 paper by Matt Visser, in which a path through the wormhole can be made in which the traversing path does not pass through a region of exotic matter. However in the pure Gauss-Bonnet theory exotic matter is not needed in order for wormholes to exist- they can exist even with no matter. #science #education #physics #physicslovers #gravity #physicists #particlephysics #gravitationalforce #astrophysics #cosmology #theoreticalphysics #quantumphysics #PhysicsOfTheUniverse #ScienceOfTheUniverse DM for image credit/removal

Cryptocoins are all about abstractive thoughts and virtual representations. Some people cannot understand Cryptocurrecies because they are too involved with the customary construct that they exist in. Even this world that we call reality is an illusory construct that has been engineered in a certain way which makes people forget that it is an illusory construct. Humans create illusory constructs to come around full circle sometimes and realize that reality in itself is a construct — #matrix #humans #bitcoin #cryptpcurrencies #illusion #reality #money #future #scifi #philosophy #mind #matter #science #time #technology
