Can mathematics and physics be unraveled? What is mathematics making?

As I talked about in a recent post, string theories, and the multiverse models they imply, have been widely criticized for their lack of testability. Some physicists argue that the problem is that the theory is more mathematics than it is physics. Is the distinction becoming fuzzier? And why isn’t that discussed? Why not bring […]

String theories, illusions, and mathematics

Back in July, David Castelvechhi blogged about a conversation between John Horgan and George Musser. I missed it when it was new, but I’m glad I didn’t miss it completely. Most of their discussion focuses on the value or viability of what has come to be known as string theory. It was a thoughtful debate […]

The Nature of Time in physics, philosophy, complexity, neuroscience and Liebniz

I ventured down a series of paths today, no doubt related, but with no quick and easy way to tie them together. So I decided to invite you to look with me and let your mind play.

I started with a couple of talks at a recent at a recent Foundational Questions Institute conference on […]

Archimedes, particle accelerators and being visual

I feel like I was pulled into a little whirlpool of interesting bits of info this morning. I was attracted to the title of David Castelvecchi’s blog: Archimedes and Euclid? Like String Theory versus Freshman Calculus. The blog reports the opening of an exhibition at the Walters Art Museum in Baltimore, showcasing one of three […]

Time, memory, illusions and mathematics

In a recent post on the Scientific American blog network, George Musser reported on talks given by neuroscientists at a conference, organized by the Foundational Questions Institute on how the brain works to construct our sense of past, present and future.

Musser’s post made some observations that were familiar to me – like the idea […]

Outer and Inner Limits of the Brain (or the body)

A recent Scientific American article on the physical limits of intelligence raised more questions for me than it answered with its intriguing analysis of neural mechanisms. The point of the article is to consider that it may be physically impossible for humanity to become more ‘intelligent’ with further evolution. I think we would all agree, […]

Suppressed Geometry?

There are countless ways to explore what may be called the two faces of mathematics – algebra and geometry. Modern mathematical systems have their roots in both algebraic and geometric thinking. Like the organs of the body which are built on the redirected sameness of cells, algebra and geometry live in all manner of relationship […]

Bayesian Models from the Eye to the Cosmos

My last post caused me to survey some things related to Bayesian statistics as they relate to mathematics and cognition. First, I want to say that despite the fact that I have been looking more closely at 19th century developments in mathematics, I didn’t know until today that Laplace, in 1814, described a system of […]

Berkeley’s Analyst and Other Things

Some of George Berkeley’s fame comes from his vehement critique of Newton’s calculus. His criticism was harsh and inspired a number of responses from contemporaries who accepted the vanishing quantities Newton used to formulate his notion of fluxions or, in modern terms, his understanding of instantaneous rates of change. The discussion that followed Berkeley’s 1734 […]

Fields, Circles and the Wisdom of Immaterial Objects

I have spent some time pointing to milestones in the history of modern mathematics where a conceptual shift produces provocative new thought – as when Riemann gave a new foundation to geometry, or when Cantor brought precision to the notion of countability. Modern mathematics, partnered with physics, increasingly refines what the human mind can perceive. […]
