Assume space-time is quantized. This would mean that space-time is broken up into discrete bits. It then follows that time is broken up into discrete bits. This disagrees with basic experience: we can start counting time at any arbitrary point. “Now” could be any time whatsoever. Moreover, we run our physical experiments at any given point; we don’t have to wait to start our clocks. But what if our ability to run experiments at any […]

Book Review: The Genial Gene
The Genial Gene: Deconstructing Darwinian Selfishness by Joan Roughgarden In The Genial Gene Joan Roughgarden seeks to replace the competitive understanding of evolution, known as sexual selection, with a cooperative one. The first sentence of her book reads, “This book is about whether selfishness and individuality, rather than kindness and cooperation, are basic to biological nature” (p. 1). So what is the argument? Taking this first line, she wants to conclude something about basic biological […]
Rewrite of Evolution
New theory of evolution! Hooray! Patched a bunch of things together to make a nice story. Fixed the little issue about fitness being circular. Expanded natural selection to apply more generally. Causal structure. Epistemological foundations. ooOoOO0Ooooooo. And it’s good fun. I swear. Epistemology, history of physics, evolution… makes me happy. You should really read it. Download here.

Genetic Drift and the Uncertainty Principle
I have previously argued that the history of species must be treated like a evolutionary trajectory: we can only appreciate a species in a relative sense, just as we must evaluate physical trajectories relative to our own motion. But what happens when we try to measure the very small in physics? We find there is a limit to the precision at which we can measure, as given by the uncertainty principle. This suggests that there […]
Dismantling Fodor’s Argument
Fodor argued that the theory of evolution is not a legitimate theory of science because it is either vacuously true or wrong. He accused Darwin of committing the intentional fallacy. (synopsis here) Insofar as he made no logical mistakes in his reasoning, we need a different strategy to defend the theory of evolution. In this post I will argue that his argument is an instance of gerneral underdetermination, and hence not a problem of evolution […]
Time and the Limits of Science
Measurement takes time; measurement is a process. So the measurement of time immediately yields this theoretical issue: Since measurement takes time, our ability to break time into ever smaller pieces will always be proportional to the method of measurement used. The faster our measurement device that measures time, the more divisible time will be. Insofar as there are limits to how fast a measurement process can occur (relativistic or other), there will be limits on […]
something about time
There is something about time that I can’t seem to stop thinking about. We measure time by agreeing upon an event and then counting from that point onward. Today is October 17, 2008 AD. It is this AD that keeps my attention. It has been 2008 years, ten months and seventeen days since the birth of Jesus of Nazareth: AD stands for Anno Domini, or year of our lord. Those not wanting to be explicitly […]
Where Does Probability Come From? (and randomness to boot)
I just returned from a cruise to Alaska. It is a wonderful, beautiful place. I zip-lined in a rain forest canopy, hiked above a glacier, kayaked coastal Canada and was pulled by sled-dogs. Anywho, as on many cruises, there was a casino, which is an excellent excuse for me to discuss probability. What is probability and where does it come from? Definitions are easy enough to find. Google returns: a measure of how likely it […]
Relativity as Informational Interdependence
Ever have the experience of sitting in traffic and believe that you are moving in reverse, only to realize a second later that you were fooled by the vehicle next to you moving forward? You were sitting still, but because you saw something moving away, you mistakenly thought you started to move in the opposite direction. Two different senses may be at work here: your sight and your balance. Lets assume that your balance did […]
