Who invented holograms?
The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region – such as a light-like boundary like a gravitational horizon.
Jun 29, 2015 · Some physicists actually believe that the universe we live in might be a hologram. The idea isn’t that the universe is some sort of fake simulation out of The Matrix, but rather that even though...

Photo: The dove on this credit-card hologram seems to rotate as you tilt the card in the light. Laser light is much purer than the ordinary light in a flashlight (torch) beam.In a flashlight beam, all the light waves are random and jumbled up. Light in a flashlight beam runs along any old how, like schoolchildren racingdown a corridor when the bell...
Photo: The hologram on this DVD case is designed to deter copyright piracy. Until the 1980s, holograms were a slightly wacky scientific idea.Then someone found a way of printing them onto metallic film and theybecame an incredibly important form of security. Proper glassholograms look much more impressive than the tiny metallic ones yousee on bankn...
Holograms were invented by a brilliant Hungarian-born physicist namedDennis Gabor (1900–1979) while he wasworking in the UK. He'd been researching optical physics in the 1940s, and carried out his breakthrough work inholography in the early 1950s. The remarkable thing about his invention is that it was many years ahead of its time:lasers, which mad...
Nov 16, 2018 · It turns out that this idea of the holographic principle or the universe is a hologram, although at first, it might seem like a completely random idea, it actually helps us to solve some of the thorniest puzzles that arise when you try to combine quantum mechanics and general relativity.
Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.
Aug 30, 2023 · Once you know the principles behind holograms, understanding how they can do all this is easy. This article will explain how a hologram, light and your brain work together make clear, 3-D images.
May 3, 2023 · IN NOVEMBER 1997, a young physicist named Juan Maldacena proposed an almost ludicrously bold idea: that space-time, the fabric of the universe and apparently the backdrop against which reality...
