“If you want to learn how cerebral blood flow works, study engineering. Study design.”

[From a colleague:] A few years ago, my brain research took some interesting turns. I was developing a theory of blood flow to the brain, specifically a theory of how the delicate blood vessels in the brain are protected from the strong pulsatility of the heartbeat. I realized that the system in the cranium that affords this protection seems to be designed. That is, it is a tuned mechanism quite analogous to vibration dampers widely used in engineering. I was haunted by the realization that the research that I was doing was essentially reverse engineering. Most of what I needed to know about pulsatile blood flow to the brain was in engineering textbooks! I was surprised as to how little some of the major paradigms in biology, especially Darwinism, contributed to my work. In fact, ignoring design obscured the most important aspects of my research. The assumption of design was heuristic.
Around that time, I came across Phillip JohnstonÃ¢â‚¬â„¢s Darwin on Trial in a bookstore, and went on to read Jonathan WellÃ¢â‚¬â„¢s Icons of Evolution, Mike BeheÃ¢â‚¬â„¢s DarwinÃ¢â‚¬â„¢s Black Box, and Bill DembskiÃ¢â‚¬â„¢s Uncommon Dissent. For perspective, I read Dawkins, Dennett, and Gould as well. When I finished reading, I was astonished. And angry! Although my scientific talents are modest, I have developed a fairly acute sense for scientific nonsense. Darwinism is nonsense. ItÃ¢â‚¬â„¢s more a philosophical bias than coherent science. It may explain some patterns and changes in gene frequency in populations, but the evidence does not even remotely support the DarwinistsÃ¢â‚¬â„¢ claim that chance and necessity fully account for the appearance of complex design in living things. That claim is nonsense. I believe that the best scientific explanation for the appearance of design in living things is that they are designed. This assumption forms the basis for my own research, and itÃ¢â‚¬â„¢s a very powerful tool. My advice to young researchers in my field is: if you want to learn how cerebral blood flow works, study engineering. Study design.
