How Scientific Experimentation is Superior to Rationality...

Now that we have looked at the differences between the experimental type of thinking and the other types we have discussed, we can see that it is superior to any of the others. Experimental thinking does, to be sure, emphasize systematization and classification, but as means, not as ends in themselves. And, along with rationalism, it emphasizes general principles and laws, but again, not as ends in themselves, but as convenient guides for making our inferences. Neither observation nor infere...

 What are Observations?

What are observations? Some philosophers have taken them to be sensory events: the occurrence of smells, feels, noises, color patches. This way lies frustration. What we ordinarily notice and testify to are rather the objects and events out in the world. It is to these that our very language is geared, because language is a social institution, learned from other people who share the scene to which the words refer. Observation sentences, like theoretical sentences, are for the most part senten...

 Natural Selection Resembles Bayesian Inference

The analogy is mathematically precise, and fascinating. In rough terms, it says that the process of natural selection resembles the process of Bayesian inference. A population of organisms can be thought of as having various 'hypotheses' about how to survive—each hypothesis corresponding to a different allele. (Roughly, an allele is one of several alternative versions of a gene.) In each successive generation, the process of natural selection modifies the proportion of organisms having each...

 An Eloquent Description of Science and Wonder

As I gathered information for this book, I was continually reminded of the reality that science, rooted as it is in the certainties of the physical world, is a process that necessarily unfolds over time. In school, science classes tend to work according to this linear model; there's a “beginning, middle, and end” to science investigations, no matter how hard teachers may fight the “cookbook” reductionism that threatens true scientific inquiry. Yet, in probing further, I came to unders...

 The Rate of Change of a Rate of Change

In scientific thought we adopt the simplest theory which will explain all the facts under consideration and enable us to predict new facts of the same kind. The catch in this criterion lies in the word 'simplest'. It is really an aesthetic canon such as we find implicit in our criticisms of poetry or painting. The layman finds such a law as dx/dt = K(d^2x/dy^2) much less simple than 'it oozes', of which it is the mathematical statement. The physicist reverses this judgment, and his statement ...
