This Mysterious Computer Could Prove Time Travel Exists | Nostalgia Nerd

Thanks to Curiosity Stream for sponsoring today’s video. ~ In 1984 something strange happened in the village of Dodleston. A BBC Micro was sitting on a counter, when it suddenly started receiving mysterious messages, which appeared to come from the 16th century. This might have gone unnoticed had local teachers, Ken Webster and Peter Trinder, not investigated to find that information was so accurate, it would be almost impossible to fake. This whole event was documented in the book “The Vertical Plane”, published in 1989. But here, tonight, we investigate deep to find out exactly what this is all about.

Mike Suffredini talks Axiom module additions to ISS, ensuring no gap in LEO station access

Posted by in category: space

It is a lesson the U.S. space program has had to learn many times over: don’t voluntarily give up a space capability without having a successor ready to go or already operational.

But for the ISS (International Space Station), a gap in LEO (low Earth orbit) scientific research capability will likely not occur when the iconic outpost ends its career, whenever that may be.

And that is in large part due to Axiom, a private space organization with private funding that will begin adding modules to the ISS in 2024 — with the goal that those added modules will then be easily disconnected from the ISS at the end of its life, thus ensuring no gap in low Earth orbit space station capability for the United States.

Artificial Intelligence Is the New Science of Human Consciousness | Joscha Bach | Big Think

Artificial Intelligence Is the New Science of Human Consciousness.

Join Big Think Edge for exclusive video lessons from top thinkers and doers: https://bigth.ink/Edge.

Can AI dream? Can it love? Can it “think” in the same way we do? The short answer is: no. AI doesn’t need to bog itself down with simple human tasks like love or dreams or fear. The AI brain posits itself in a much grander scale first and then works backwards to the more human way of thinking. Joscha Bach suggests that much rather than humanoid robots, we are more likely to see AI super-brains developed by countries and larger companies. Imagine a computer brain that is designed to keep the stock market balanced, or detect earthquakes an ocean away that could sound alarms on our shores… that sort of thing.

Joscha Bach — Reconciling consciousness with physicalism

Posted by in categories: cosmology, neuroscience, physics

Speaking at the 6th International FQXi Conference, “Mind Matters: Intelligence and Agency in the Physical World.”

The Foundational Questions Institute (FQXi) catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality but unlikely to be supported by conventional funding sources.

Exploring a New Transparent Solar Cell Breakthrough

Posted by in categories: mobile phones, nuclear energy, sustainability

We’ve been seeing a wave of innovations in solar panel technology, like perovskite solar cells, solar tiles and roofs, and organic panels. But what if we could harvest solar energy from the windows and skylights of our homes and skyscrapers, or even from our car windows and cellphone screens? Let’s explore transparent solar panels and how they stack up against conventional panels. Could transparent solar cells be the future of solar energy? Or does it remain to be unseen?

Three CERES satellites for French DGA successfully launched

Posted by in category: satellites

The French Armament General Directorate’s (DGA) ‘Capacité de Renseignement Electromagnétique Spatiale/Space-based Signal Intelligence Capability’ satellites have been successfully launched.

An Arianespace Vega rocket lifted off with the satellites from the European spaceport in French Guiana.

Known by the French acronym CERES, the satellites were designed and built by Airbus Defence and Space, and Thales.

Researchers are using artificial intelligence to create better virtual reality experiences

Posted by in categories: augmented reality, robotics/AI, virtual reality

Working at the intersection of hardware and software engineering, researchers are developing new techniques for improving 3D displays for virtual and augmented reality technologies.

Virtual and augmented reality headsets are designed to place wearers directly into other environments, worlds and experiences.

While the technology is already popular among consumers for its immersive quality, there could be a future where the holographic displays look even more like real life. In their own pursuit of these better displays, the Stanford Computational Imaging Lab has combined their expertise in optics and artificial intelligence. Their most recent advances in this area are detailed in a paper published in Science Advances and work that will be presented at SIGGRAPH ASIA 2021 in December.
