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 […]

What can’t be sensed

Step by step, our ideas about the nature of our reality have moved far from the sensory constructions of space and time that define our immediate experience. And once fully outside the knowledge brought with sensation, we lose our footing.  It’s difficult to manage ‘what can’t be sensed.’  But our conceptual difficulties with quantum mechanics […]

What’s the tool, what’s the reality, what are we doing?

I am intrigued by the current debate in physics concerning the significance of the wave function in quantum theory.  The nature of the debate opens the door to a host of philosophical issues surrounding both physics and mathematics.  In an article appearing in the June issue of Scientific American, I was introduced to a relatively […]

Multiverse, busses and emergent space-time

There was once what many call a ‘foundational crisis in mathematics’ – disputes among mathematicians about both their ideas and their methods.  But while one needn’t now address the relationship between mathematics and reality in order to pursue a successful career in mathematics, the conceptual and experimental puzzles of modern physics likely reflect a similar […]

Quantum mechanical biology

In my guest blog for Scientific American, I wrote about the work of Bob Coecke who has designed a graphical mathematics, based on a branch of mathematics called category theory. He uses this diagrammatic calculus to describe and investigate quantum mechanical processes.  Coecke’s work has found application in biology and linguistics, suggesting some interesting links […]

Quantum Mechanical Words and Mathematical Organisms

My post appeared on the Scientific American Guest Blog this morning.  Here’s the link:

Quantum Mechanical Words and Mathematical Organisms

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 […]

The light that Einstein sees

I read another New Scientist article today. The article was written by Brian Greene. While it didn’t give me a lot of new information, it made an interesting point about what it means (and when is it particularly effective) to take our mathematics seriously.  He talked about Einstein’s insight regarding the speed of light.  It […]

Time, mathematics and Plato’s cave

Sean Carroll, Theoretical Physicist at the California Institute of Technology has recently published a new book.  Entitled The Particle at the End of the Universe: How the Higgs Boson Leads us to the Edge of a New World it discusses the importance of the Higgs boson as well as the significance of the extraordinary work […]

Mathematics and the Higgs

In general, I tend to resist talking about the thing that everyone is talking about, but I find reason to make an exception today.  I do want to say something about yesterday’s announcement from physicists at the LHC that they saw the Higgs particle.  Frank Wilczek describes the significance of this observation (particularly nicely) in […]
