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 […]

Deriving Natural Selection = Fitness × Acceleration
As you can see from my previous post, I now have postulated a direct relation between Natural Selection and Fitness (N.S.=F.×A.). This relation follows from the theory. The short short short version of the theory is this general postulate: one organism’s traits are another’s environment and vice versa. Hence all competition can be viewed as environmental phenomena. This gives Natural Selection as a result of Fitness and an environmental factor, which I refer to as […]
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.

Hypotheses Natura Non Fingo
Newton famously wrote [1] [2]: I have not as yet been able to discover the reason for these properties of gravity from phenomena, and I do not feign hypotheses… It is enough that gravity does really exist and acts according to the laws I have explained, and that it abundantly serves to account for all the motions of celestial bodies. as a response to those who challenged him to provide causes of gravity. He said, […]
Aristotle’s Theory of TOPOS (Place)
[This is something I wrote before I had this blog, but I really like it and hope the readers here will find it interesting.] The task of explaining Aristotle’s theory of place lies in the interpretation of this sentence: “Hence the place of a thing is the innermost motionless boundary of what contains it,” (Physics IV 212a20). Now the idea of a motionless boundary for perceptible and obviously movable objects seems impossibly counterintuitive. However, using […]
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 […]
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 […]
Economics
Readers of this blog may have noticed a lack of updates recently. I can’t apologize: I’ve been eating, breathing and drinking philosophy for so long, that now that I have written everything I wanted to write, I feel free. I wish it on all of you. [Happy New Year Everyone!] But this doesn’t stop me from thinking. I was at a Christmas party and got talking with an Indonesian economics grad student. He was researching […]
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 […]
