The Quantum Feedback Loop was pleased to welcome back Dr. Louis Rosenberg, an engineer, researcher, inventor, and entrepreneur who was a pioneer in virtual reality technology in the early 1990s. Louis speaks about his new book, Our Next Reality, in which he and co-author Alvin Graylin present the benefits and risks of virtual reality.

Louis traces VR's development from early days to present, when the technology's combination with AI is quickly enabling it to create immersive experiences that consumers may not be able to differentiate from reality. As Meta, Google, and other companies race to commercialize VR, Louis makes a number of recommendations for laws that could protect our immersive rights and help to realize the many benefits that VR could deliver in the very near future.

For more on Louis and his company Unanimous AI, which is developing technology to connect groups and amplify their collective intelligence modelled on the biological principle of swarm intelligence, listen to our discussion with Louis in early 2024 at https://rss.com/podcasts/quantum-feedback/1402711/.

Astronomer Lindsay House returned to the podcast to update us on her citizen science project called Dark Energy Explorers. Around the globe, 20,000 explorers are using data from the world’s third largest telescope to observe patterns in the movement of galaxies from between 9-11 billion years ago, to understand how the expansionary force of dark energy operates. As Lindsay explains, dark energy, which comprises 70% of the universe’s mass, is undetectable to our instruments but exerts an expansionary force by adding space between physical objects. Since 1998, we’ve known that the universe is expanding more rapidly over time, at rate that was thought to be a constant rate of acceleration. However, new evidence is pointing to an unexpected reduction in the speed of expansion. What function is dark energy exercising in time, if dark energy's force can both increase and decrease the rate of universal expansion? Would dark energy's variability lead to a revision of the “lambda-CDM” model of cosmology, which is based on a constant expansion rate? The observations of the Dark Energy Explorers community from 159 countries, sharing knowledge translated into 9 languages, are contributing to expanding understanding of the still-mysterious expansionary force of dark energy. The Dark Energy Explorers are, as Lindsay says, the humans “in the loop,” as the capabilities of AI and machine learning help to make vast numbers of groundbreaking connections with astronomical data. Hear Lindsay tell the story of Dark Energy Explorers, and how scientists are coming to understand more about dark energy, the fascinating and invisible force of expansion.

We speak with Dr. Deirdre Haskell, Director of the Fields Institute for Research in Mathematical Sciences at the University of Toronto, about how mathematics applies to so many aspects of our daily lives and is at the forefront of the latest developments in science and technology. The Fields Institute brings together specialists in different mathematical branches from around the globe to integrate knowledge and expand the frontiers of mathematics. Mathematics touches all of us, whether it’s with GPS navigation, medical and astronomical imaging, modelling for climate change and finance, or artificial intelligence with its Large Language Models like ChatGPT. Explaining the relevance of mathematics in a way that’s accessible to all, Deirdre brings us into a critically important conversation about the direction of a future that’s increasingly mathematical.
