Quantum leap: how we discovered a new way to create a hologram

Once, holograms were just a scientific curiosity. But thanks to the rapid development of lasers, they have gradually moved center stage, appearing on the security imagery for credit cards and bank notes, in science fiction movies—most memorably Star Wars—and even “live” on stage when long-dead rapper Tupac reincarnated for fans at the Coachella music festival in 2012. …

Black holes are like a hologram

The theory of relativity describes black holes as being spherical, smooth and simple. Quantum theory describes them as being extremely complex and full of information. New research now proposes a surprising solution to this apparent duality. Source: https://earthsky.org/space/black-holes-are-like-a-hologram…

Black holes? They are like a hologram

According to new research by SISSA, ICTP and INFN, black holes could be like holograms, in which all the information to produce a three-dimensional image is encoded in a two-dimensional surface. As affirmed by quantum theories, black holes could be incredibly complex, and concentrate an enormous amount of information in two dimensions, like the largest hard disks that exist in nature….

Canceled Dyson Electric Car Would’ve Had a 600-Mile Range Per Charge

Remember that electric car project that Dyson finally cancelled in October? It would’ve had a top speed of 125 miles per hour, going from 0 to 60 in 4.8 seconds, and “would have been able to go 600 miles on a single charge,” reports Digital Trends, citing Sir Dyson’s new interview with the Sunday Times: In comparison, Tesla’s Model S is…

The BBC’s 1992 TV Show About VR, 3D TVs With Glasses, and Holographic 3D Screens

dryriver writes: 27 years ago, the BBC’s “Tomorrow’s World” show broadcasted this little gem of a program [currently available on YouTube]. After showing old Red-Cyan Anaglyph movies, Victorian Stereoscopes, lenticular-printed holograms and a monochrome laser hologram projected into a sheet of glass, the presenter shows off a stereoscopic 3D CRT computer display with active shutter glasses. The program then takes us…

Ask Slashdot: What Happened To Holographic Data Storage?

dryriver writes: In an episode of the BBC’s Tomorrow’s World broadcasted all the way back in 1984, a presenter shows hands-on how a laser hologram of a real-world object can be recorded onto a transparent plastic medium, erased again by heating the plastic with an electric current, and then re-recorded differently. The presenter states that computer scientists are very interested in…

Hologram-Like Device Animates Objects Using Ultrasound Waves

An anonymous reader quotes a report from The Guardian: Researchers in Southampton have built a device that displays 3D animated objects that can talk and interact with onlookers. A demonstration of the display showed a butterfly flapping its wings, a countdown spelled out by numbers hanging in the air, and a rotating, multicolored planet Earth. Beyond interactive digital signs and animations,…

Leaked Documents Reveal Saudi Arabia’s Plans For Its Next Megacity

An anonymous reader quotes a report from The Verge: A new report from The Wall Street Journal shares some of the proposals for Saudi Arabia’s biggest megaproject yet: a city built in the desert named Neom, where robots will outnumber humans and hologram teachers will educate genetically-enhanced students. These are only proposals, of course, dreamt up by American consulting firms like…

Microsoft Demos Hologram ‘Holoportation’

Microsoft “continues to plug away at making holoportation possible,” reports ZDNet: In a new demonstration, officials showed off a scenario where a life-sized holographic representation of a person could be beamed into a scenario with real-time simultaneous language translation happening — a communication scenario on which Microsoft has been working for years. At Microsoft’s Inspire partner show (which is co-located with…
