Reality? Of a kind.
June 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.
Quantum entanglement: a little bit like dancing twins connected by unseen forces.
May 8, 2013 Physicist Marcelo Gleiser recalls his early interest in competing interpretations of the quantum world. Now a successful researcher in his own right, he wonders if it's time to switch gears and turn his casual interest into a professional pursuit.
May 1, 2013 How do you explain it when unseen forces act across time and space? The fact is that reality is far stranger than we can suppose when we step into the quantum world. Physicist Marcelo Gleiser lays out the bones of this modern ghost story.
April 24, 2013 The quantum world is mysterious. It behaves in ways that just don't match up with what we see in the larger world. Commentator Marcelo Gleiser probes the space between what we see and what we know in search of a bridge between both realities.
Not Schrödinger's (unfortunate) cat.
January 23, 2013 Reality is stranger than fiction; this is certainly the case within the quantum world, where objects can be in two places at the same time. Experiments confirm this can also be true for large molecules. The next step is to try it with living beings.
October 17, 2012 This year's Nobel Prize in physics celebrates amazing experiments that have the potential to elucidate some of Nature's deepest secrets. They also and have the potential to lead us down the path to a world transformed by revolutionary quantum applications.
October 15, 2012 These days I am kinda, sorta, maybe coming to think that until we understand Quantum Mechanics we may not understand much at all.
June 6, 2012 Can we explain the origin of all things from nothing? First we need to understand what nothing means and how the human mind creates.
June 5, 2012 The Uncertainty Principle says that at some level the world turns fuzzy and the idea of properties as perfectly objective, knowable attributes gets inherently fuzzy.
May 22, 2012 We simply can't imagine, as in draw a picture in our heads, what quantum mechanics is pointing us to in terms of a "picture" of reality. We don't have the mental machinery to create images in our heads that embrace the reality our experiments imply.
Heads or tails? It should be a 50-50 chance either way.

May 14, 2012 We like to think that every event we see in the universe has a cause. We are wrong.
May 10, 2012 Today I begin an ongoing series of little posts on what makes quantum mechanics so strange.
May 2, 2012 Has physics done away with the need for philosophy and theology? While the debate rages on, we might wonder if it's the job of science to deal with final questions.

November 2, 2011 Did the universe originate from nothing? In a new NOVA series, Brian Greene will be describing some of the modern scientific views on space and time.
