Although the article makes a great case regarding the evolutionary design of the wheel, I was more interested in his continued reference to constructal law.
The Constructal Theory
Prof. Bejan has a web Portal for Constructal Theory. It's not much to look at (at the time of this writing) but buried within the hot pink boxes are loads of information regarding contructal law.
I would love to sum up constructal theory here, but I'm afraid that is just not possible. The multitude of examples on his website where contructal law can be used is nothing short of astounding: making biology and economics like physics; sports; technology; social interactions; web (SEO) traffic; and many many others. It is hard to tell if Adrian is an engineer or something else. To be able to take a single unifying law and apply it to any number of areas of study is something I think theoretical physicists would like to have for the universe.
I urge you to open your mind a take a look at the constructal theory web portal. As Adrian concludes in the article I read, the best way to describe constructal law is that it unites animate and inanimate design phenomena and therefore allows the study of evolution within our lifetimes, not the eons it takes in nature. Fascinating.
