In this stunning 360° video, former U.S. inmate Rickey Jackson, who was wrongfully imprisoned for 40 years (including being on death row and in solitary), tells the story of his rebirth. At the time of his release, Jackson served the longest sentence of any exonerated U.S. inmate. Read more: https://www.theatlantic.com/vi....deo/index/577639/sen

Join a physicist, a neuroscientist, and a linguist as they explore the deep enigmas of time. Time feels like it flows, but does it? Time seems to have a built-in direction, from past to future, but is that real or merely a quality imposed by the human brain? Time on earth elapses at a uniform rate, so why does the human experience of time seem so varied? How do various neurological afflictions change the perception of time? And underneath it all, how does human language impact our ability to think about time and fully experience its rich and mysterious contours?

This statement is false. Think about it, and it makes your head hurt. If it’s true, it’s false. If it’s false, it’s true. In 1931, Austrian logician Kurt Gödel shocked the worlds of mathematics and philosophy by establishing that such statements are far more than a quirky turn of language: he showed that there are mathematical truths which simply can’t be proven. In the decades since, thinkers have taken the brilliant Gödel’s result in a variety of directions–linking it to limits of human comprehension and the quest to recreate human thinking on a computer. This program explores Gödel’s discovery and examines the wider implications of his revolutionary finding. Participants include mathematician Gregory Chaitin, author Rebecca Goldstein, astrophysicist Mario Livio and artificial intelligence expert Marvin Minsky.

Forget what you think you know about dark matter. After a 30-year search for a single, as yet unidentified, species of dark matter particle that would make up some 25% of the mass of the universe, physicists are starting to consider novel explanations. Some envision invisible matter hiding within the folds of extra spatial dimensions. Others suggest not one kind of dark matter particle, but numerous species inhabiting a shadow universe. Others still conjecture that dark matter doesn’t exist, and instead propose that the laws of gravity need modification. We’ll bring together leading thinkers on dark matter—the revolutionary and conventional alike—for a distinctly unconventional discussion on the dark universe.
