(Jihyuck) catastrophe theory
One day Renjun asks him, “Do you think Donghyuck is hot?”
And, well, it all goes downhill from there.

A mathematical method for dealing with discontinuous and divergent phenomena has only recently been developed. The method has the potential for describing the evolution of forms in all aspects of nature, and hence it embodies a theory of great generality; it can be applied with particular effectiveness in those situations where gradually changing forces or motivations lead to abrupt changes in behavior. For this reason the method has been named catastrophe theory. Many events in physics can now be recognized as examples of mathematical catastrophes. Ultimately, however, the most important applications of the theory may be in biology and the social sciences, where discontinuous and divergent phenomena are ubiquitous and where other mathematical techniques have so far proved ineffective. Catastrophe theory could thus provide a mathematical language for the hitherto “inexact” sciences.

Of some fields it is difficult to tell whether they are sound or phony. Perhaps they are both. Catastrophe theory started out with impeccable credentials, then turned out to resemble a three-dollar bill. Dynamic programming overcame a questionable background to be seen as substantial.

Catastrophe theory analyzes degenerate critical points of the potential function — points where not just the first derivative, but one or more higher derivatives of the potential function are also zero. These are called the germs of the catastrophe geometries. The degeneracy of these critical points can be unfolded by expanding the potential function as a Taylor series in small perturbations of the parameters.

Faith and science
The two books offered today were both written in order to align later seventeenth century theories of the earth with the results of scientific exploration and a fair bit of conjecture with the anglican faith. The ideas set forth here can be discarded as a dead end path, but I like to think of them rather as a stop along a much wider road of speculation with much to offer as inspiration for New…
