Shoot! I thought I was the only one doing cavitation studies. It's a pretty neat process to observe. Granted my studies have not been at the level of 'supercavitation' I can only imagine the flowrate needed to produce a cavity large enough to enclose an entire airfoil. Does anyone know of the energy required to release the air from the water? I've observed that at small deltas in pressure at and at flowrates as small at 15 gal/min small bubbles can collect on the rough cavities of small air foils, while smoother ones fail to yield the same results. Save the dolphins-take a plane.
Having just finished the book yesterday I was pleasantly surprised to see the review on/. While reading it my mood alternated between excitement and remorse. Greene's description of string theory as the merger between relativity and quantum mechanics deserves an applause, however string theory seems to do away with some of the older convention such as infinitely small points and infinitely massive areas in space that seemed to give our reality that magical flare.
As quantum mechanics probes down to the sub atomic level I can't help but feel like physicists are merely creating conventions for the phenomena that they cannot theoretically explain. I think that this is one of the main differences between classical and modern physics. Classical physics discovered the physical laws that govern our universe while modern physics speculates a reality that fits absurdly abstract mathematical models, which is the feeling that the book left me with.
