Jul 15, 2014 — Understanding how things work in the quantum world is both fun and mind-bending. Physicist Adam Frank suggests spending a minute watching this video on the wave-particle duality.
Jul 9, 2014 — We don't have all the answers; many big questions hang over the world of theoretical physics. Is this business as usual? Or symptom of a major crisis in our understanding of nature?
Feb 5, 2014 — Stephen Hawking wants to do away with black holes (as we know them) so he can save the two pillars of modern physics: general relativity and quantum mechanics. At stake is our understanding of the nature of space and time, and how matter affects, and is affected by, both.
Dec 18, 2013 — What was there before the universe began? It's not a question we can really answer with the science we have at hand, says commentator and physicist Marcelo Gleiser.
Dec 4, 2013 — Is the brain a sort of quantum computer? What is consciousness? Marcelo Gleiser's brain is buzzing with big questions after participating in a conference that asked if quantum physics plays a role in how we think.
Sep 4, 2013 — Writing in Nature, a team of scientists say they've figured out how to reduce the infrastructure needed for such a system.
Aug 14, 2013 — A technological revolution that is still playing out today began with new ideas about how atoms and subatomic particles work. Commentator Marcelo Gleiser tells the story of Danish physicist Niels Bohr and the work that changed how we live today.
Jul 30, 2013 — For 60 years researchers have been searching for a way to unite our separate understandings of the very large and the very small into a single coherent theory. Now a remarkable new idea is raising eyebrows, and hopes, around the world. Has the path to solve this problem just been found?
Jun 12, 2013 — Science is often accused of extinguishing our enchantment with the world, of being too cold and rational. Quite the opposite is true, says Marcelo Gleiser. Modern science has restored a sense of wonder to the world with its revelations of objects unseen and realities unknown.
May 29, 2013 — Can we act backwards in time? We can if we're talking about the world of quantum particles! It seems that the human mind plays a role in this time puzzle, too. Our role may even have something to do with why the universe exists.
