Things versus Relations and Objects versus Properties

In the August issue of Scientific American, Meinard Kuhlmann addresses, yet again, the conceptual difficulties inherent in the interpretations of experimental data of modern physics.

…the particle interpretation of quantum physics, as well as the field interpretation, stretches our conventional notions of “particle” and “field” to such an extent that ever more people think the […]

A brief note and a little from Deutsch

I’m short on time today and working on a guest blog which I hope to be able to provide a link to shortly. But I did begin exploring a website that has short video interviews with some of my favorite thinkers. I found among a list of participants on the website Closer To Truth, Gregory […]

Structure, structure and more structure

I was expecting to write about a paper I found recently by Oran Magal, a post doc at McGill University, On the mathematical nature of logic. I was attracted to the paper because the title was followed by the phrase Featuring P. Bernays and K. Gödel

I’m often intrigued […]

Wigner, Persig, Leibniz and the nature of reality

I saw an opinion piece by Stephen Ornes, in the March 16 issue of New Scientist which ties the ongoing debate about the nature of mathematical ideas, to a modern one about money and ownership. Ornes argues that patentability is one of the most hotly contested issues in software development. The problem, as many see […]

Are we finding the mathematical structure of reality?

I’m intrigued by Max Tegmark’s conviction that the universe is, itself, a mathematical structure. He presented his ideas, again, on February 15 at the recent annual meeting of AAAS, in a symposium called Is Beauty Truth? He said that he has just completed a book on the same topic. I listened to the entire session […]

Infinities, metaphors and being human

Our thoughtful, imaginative worlds are married to our physical experiences but the subtleties of their union are almost impossible to fully appreciate. Mathematics, I often argue, has the potential to provide a better view of the situation, perhaps because of the inexhaustible depth of its abstraction, together with the precision it brings to a concept, […]

Julian Barbour, from metaphysics to mathematics to us

Julian Barbour is a theoretical physicist with a clear interest in tackling foundational issues and the errors of judgment that can lead physics theories astray. One of these candidates for a mistaken judgment is time itself, and in 1999 Barbour authored the book The End of Time published by the Oxford University Press. He wrote […]

Computational Linguistics, Matter and Meaning

Not long ago I wrote about the work of Bob Coecke, an Oxford University physicist, who is pioneering an application of category theory to quantum mechanics. In that post I referred to the work he is also doing with language, using the same kind of graphic structures. I drew attention to the fact that category […]

Kuhn, Gödel, on being wrong and being heroic

Three things I read today converged in a way I had not anticipated and they all had something to do with truth. First, there was the announcement of the Foundational Questions Institute’s 4th essay contest. Entrants are invited to address this topic: Which of Our Basic Physical Assumptions Are Wrong? Scientific American is a cosponsor […]

That something out of nothing problem…

It seems that quite a number of categorical remarks got thrown around by Lawrence Krauss – about philosophers, theologians and physicists – in the discussions surrounding his recent book A Universe From Nothing.

But, as is often the case, these kinds of categorical judgments, that question the value of very different kinds of work, do […]
