Creating 3D objects with sound

Scientists from the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Medical Research and the Institute for Molecular Systems Engineering and Advanced Materials at Heidelberg University have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed.

These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering. The results of the study were published in the journal Science Advances.

Additive manufacturing or 3D printing enables the fabrication of complex parts from functional or . Conventional 3D printing can be a slow process, where objects are constructed one line or one layer at a time. Researchers in Heidelberg and Tübingen now demonstrate how to form a 3D object from smaller building blocks in just a single step.

This tech can print 3D objects with sound in ‘one-shot’ process

The “one-shot” process paves the path for cutting-edge 3D cell culture methods with biomedical engineering applications, claim the scientists.

German scientists have created a new technology that helps them print 3D objects with sound waves.

The design creates pressure fields using several acoustic holograms, which can be used to print solid particles, gel beads, and even living cells, according to the study released on Thursday.

Are Holograms the Next Zoom?

Proto is betting that companies will view their 7-foot-tall holographic projection boxes as an alternative for in-person meetings. At least a half-dozen startups and giants like Google and Microsoft already are.

Why more and more physicists consider space and time to be “illusions”

O.o! If the universe is some sorta hologram then this could be a clue to our actual reality.

Last December, the Nobel Prize in Physics was awarded for experimental evidence of a quantum phenomenon that has been known for more than 80 years: entanglement. As envisioned by Albert Einstein and his collaborators in 1935, quantum objects can be mysteriously correlated even when separated by great distances. But as strange as the phenomenon may seem, why is such an old idea still worthy of the most prestigious award in physics?

Coincidentally, just weeks before the new Nobel laureates were honored in Stockholm, another team of respected scientists from Harvard, MIT, Caltech, Fermilab and Google reported that they ran a process on Google’s quantum computer that could be interpreted as a wormhole. Wormholes are tunnels through the universe that can function as a shortcut through space and time and are loved by science fiction fans, and although the tunnel realized in this latest experiment only exists in a two-dimensional toy universe, it could be a breakthrough for the future represent research at the forefront of physics.

But why does entanglement have to do with space and time? And how can it be important for future breakthroughs in physics? Properly understood, entanglement means that the universe is what philosophers call “monistic,” that is, at the most fundamental level, everything in the universe is part of a single, unified whole. It is a defining property of quantum mechanics that its underlying reality is described in terms of waves, and a monistic universe would require universal functioning. Decades ago, researchers such as Hugh Everett and Dieter Zeh showed how our everyday reality can emerge from such a universal quantum mechanical description. But it is only now that researchers such as Leonard Susskind and Sean Carroll are developing ideas as to how this hidden quantum reality could explain not only matter but also the structure of space and time.

Skip Zoom? Holographic tech allows you to ‘beam’ into your next meeting

The hologram device has been announced as a CES 2023 Innovation Awards Honoree. That’s two times in a row.

Zoom-like webcam chats could be going the way of the dodo, a new holographic technology is making waves to bridge the gap between the real and virtual worlds.

The original, patented hologram device from Proto M, created by a Los Angeles firm called Proto, was this week announced as a CES 2023 Innovation Awards Honoree in the category of Digital Health.

You’ll Soon Be Able To Run Holograms On Your Smartphone

I had many ideas on how to improve Twitter, and a communication paradigm was one. The iPhone changed phones, and was a device. Twitter has no device to add to its portfolio. People have no desire to add products to Twitter portfolio to boost revenues. iPhone revenue surpassed computers, therefore it is very easy for Twitter to develop its portfolio to include better more reliable forms of revenue than advertising. A device can make a lot of money if it is a “paradigm” like an iPhone that completely changed our understanding of what a phone can be.

In 1943, Thomas Watson, the president of IBM, famously predicted the world market for computers would top out at “maybe five” of the machines. He was wrong – you likely have more than that in your own house, let’s face it – but at the time, it made sense. After all, if computers were still gigantic, vacuum-tube-powered addition machines, you probably wouldn’t want more than about five either.

It’s a similar story with holograms. Even back in the 1990s, more than 40 years after Dennis Gabor first came up with the idea of using wavefront interference to reconstruct images in three dimensions, science fiction was still assuming the need for entire decks and suites to power our holographic adventures.

In fact, they can run on a smartphone.

China Shows Off High-Powered Laser That Can ‘Write’ In The Air

Movie plots often use holograms to give the scene a scientific or cooler essence. However, researchers have made these futuristic scenes a reality. According to reports, Scientists in China showcased a laser that can create Chinese characters out of thin air.

Although lasers often have a long-range, you can only see them when the light lands on a surface. However, dust particles made an exception. But this is entirely different and looks like something out of a sci-fi movie.

Scientists have already used lasers to create a range of optical illusions. However, it required mediums like dust and clouds to do so. But according to reports, with the new device, researchers are able to draw patterns using ultra-short laser pulses.

Theory claims to offer the first ‘evidence’ our Universe is a hologram

While theories of holographic universes have been around since the 1990s, the latest study, published in the journal Physical Review Letters, contains the first proof, the researchers say.

To find the ‘evidence’, the researchers developed models of the holographic Universe that can be tested by peering back in time as far as 13 billion years, at the furthest reaches of the observable Universe. These models depend on the theory of quantum gravity, a theory that challenges the accepted version of classical gravity. The holographic principle says gravity comes from thin, vibrating strings which are all holograms of a flat, 2D Universe.

Recent advances in telescopes and sensing equipment have allowed scientists to detect a vast amount of data hidden in the ‘white noise’ or microwaves left over from the moment the Universe was created. Using this information, the team was able to make comparisons between networks of features in the data and quantum field theory. They found some of the simplest quantum field theories could explain nearly all cosmological observations of the early Universe.
