In this video, we’ll sit down in our time machine and go forward a few millenniums into the future, to see where we would be progressing as a civilization.

Researchers at the University of California, Irvine have discovered that the safe operation of a negative pressure room—a space in a hospital or biological research laboratory designed to protect outside areas from exposure to deadly pathogens—can be disrupted by an attacker armed with little more than a smartphone.
According to UCI cyber-physical systems security experts, who shared their findings with attendees at the Association for Computing Machinery’s recent Conference on Computer and Communications Security in Los Angeles, mechanisms that control airflow in and out of biocontainment facilities can be tricked into functioning irregularly by a sound of a particular frequency, possibly tucked surreptitiously into a popular song.
“Someone could play a piece of music loaded on their smartphone or get it to transmit from a television or other audio device in or near a negative pressure room,” said senior co-author Mohammad Al Faruque, UCI professor of electrical engineering and computer science. “If that music is embedded with a tone that matches the resonant frequency of the pressure controls of one of these spaces, it could cause a malfunction and a leak of deadly microbes.”
A trip deep into the far future, to the End of Earth. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ For most of human history, the end of Earth, the Universe, and Time itself were all identical, now we know the world will end in 4 billion years, long before the Universe begins to wind down. Today we will ask how we can extend that, and keep Earth around for far longer.

It’s not really a Star Wars story unless there’s a lovable or memorable droid stealing the spotlight. But, when you really stop and think about it, there’s also something profoundly tragic about the role artificial lifeforms play in the Star Wars universe.
The team had two alternate hypotheses: The first was that the optimal music tempo for beat synchronicity would be determined by the time constant of the body. This is different between species and much faster for small animals compared to humans (think of how quickly a rat can scuttle). The second was that the optimal tempo would instead be determined by the time constant of the brain, which is surprisingly similar across species.
“After conducting our research with 20 human participants and 10 rats, our results suggest that the optimal tempo for beat synchronization depends on the time constant in the brain,” said Takahashi. “This demonstrates that the animal brain can be useful in elucidating the perceptual mechanisms of music.”
The rats were fitted with wireless, miniature accelerometers, which could measure the slightest head movements. Human participants also wore accelerometers on headphones. They were then played one-minute excerpts from Mozart’s Sonata for Two Pianos in D Major, K. 448, at four different tempos: Seventy-five percent, 100%, 200% and 400% of the original speed.
2bsirius video about: Arthur C. Clarke formulated the following three “laws” of prediction: 1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. 2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. 3. Any sufficiently advanced technology is indistinguishable from magic.

With mathematical modeling, a research team has now succeeded in better understanding how the optimal working state of the human brain, called criticality, is achieved. Their results mean an important step toward biologically-inspired information processing and new, highly efficient computer technologies and have been published in Scientific Reports.
“In particular tasks, supercomputers are better than humans, for example in the field of artificial intelligence. But they can’t manage the variety of tasks in everyday life —driving a car first, then making music and telling a story at a get-together in the evening,” explains Hermann Kohlstedt, professor of nanoelectronics. Moreover, today’s computers and smartphones still consume an enormous amount of energy.
“These are no sustainable technologies—while our brain consumes just 25 watts in everyday life,” Kohlstedt continues. The aim of their interdisciplinary research network, “Neurotronics: Bio-inspired Information Pathways,” is therefore to develop new electronic components for more energy-efficient computer architectures. For this purpose, the alliance of engineering, life and natural sciences investigates how the human brain is working and how that has developed.
Gallery QI — Becoming: An Interactive Music Journey in VR — Opening Night. November 3rd, 2022 — Atkinson Hall auditorium. UC San Diego — La Jolla, CA
By Shahrokh Yadegari, John Burnett, Eito Murakami and Louis Pisha.
“Becoming” is the result of a collaborative work that was initiated at the Opera Hack organized by San Diego Opera. It is an operatic VR experience based on a Persian poem by Mowlana Rumi depicting the evolution of human spirit. The audience experiences visual, auditory and tactile impressions which are partly curated and partly generated interactively in response to the player’s actions.
“Becoming” incorporates fluid and reactive graphical material which embodies the process of transformation depicted in the Rumi poem. Worlds seamlessly morph between organic and synthetic environments such as oceans, mountains and cities and are populated by continuously evolving life forms. The music is a union of classical Persian music fused with electronic music where the human voice becomes the beacon of spirit across the different stages of the evolution. The various worlds are constructed by the real-time manipulation of particle systems, flocking algorithms and terrain generation methods—all of which can be touched and influenced by the viewer. Audience members can be connected through the network and haptic feedback technology provides human interaction cues as well as an experiential stimulus.
While the piece is a major artistic endeavor, it also showcases a number of key technologies and streaming techniques for the development of musical content in XR. The spatialization system Space3D, developed at Sonic Arts and implemented to run on advanced GPUs, is capable of creating highly realistic spatial impressions, and recreating the acoustics of the environment based on the virtual models in real-time using advanced multi-processing ray-tracing techniques.
“Becoming” premiered at SIGGRAPH 2022, Immersive Pavilion in Vancouver, Canada in August 2022. Opera America and San Diego Opera showcased an early preview of this work as part of the first Opera Hack presentations in 2020.
