This is pretty good, and it will exercise your mind for a minute. Source: Saturday Morning Breakfast Cereal The distinction between mathematical notation and its underlying reality is a crucial one. The first is an invention of humans, the second is universal. In fact, I've increasingly become convinced that the second actually is the universe, … Continue reading SMBC: The universality of mathematics, but not notation
This is a subject that we've discussed repeatedly here, so I thought you might find Tegmark's narration of this video interesting. http://www.youtube.com/watch?v=HGG4HmlotJE I'm pretty sure that mathematics are not only something humans created, that they are based on relations we observe in the world, but beyond that, I remain largely agnostic on the Mathematical Universe Hypothesis … Continue reading Max Tegmark and MinutePhysics on the mathematical universe
A slightly different point of view on the mathematical universe, as only Zach Weiner can deliver. (Click through to see the full sized version.) via Saturday Morning Breakfast Cereal.
I recently read Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the fourth and final post in a series on the concepts and views he covers in the book. The previous entries were: Tegmark’s Level I Multiverse: infinite space Tegmark’s Level II Multiverse: bubble universes … Continue reading Tegmark’s Mathematical Universe Hypothesis
I recently finished reading Max Tegmark’s latest book, ‘Our Mathematical Universe‘, about his views on multiverses and the ultimate nature of reality. This is the second in a series of posts on the concepts and views he covers in the book. Tegmark postulates four levels of multiverse. In the first post of this series, I described Termark's Level I … Continue reading Tegmark’s Level II Multiverse: bubble universes
James Franklin has an interesting piece today at Aeon, asking what exactly mathematics is. He looks at Nominalism and Platonism, but discounts both in favor of Aristotelian Realism, which is something I'd not heard of before but seems equivalent to the idea that mathematics is empirical. What is mathematics about? We know what biology is about; … Continue reading What is mathematics about? – James Franklin – Aeon
If you’re a multiverse skeptic, you should know that there are many potential weaknesses in the case for parallel universes, and I hope you’ll find my cataloging of these weaknesses below useful. To identify these weaknesses in the pro-multiverse arguments, we first need to review what the arguments are. via Are Parallel Universes Unscientific Nonsense? … Continue reading Are Parallel Universes Unscientific Nonsense?
Jim Baggott has written an important book, 'Farewell to Reality: How Modern Physics Has Betrayed the Search for Scientific Truth', which takes a hard look at many modern ideas in theoretical physics, and finds that many of them are not science. Philosophy of science Baggott begins with a chapter on basic philosophy of science, identifying … Continue reading Farewell to Reality
