Q:What is YOUR take on Louis Crane's idea of meduso-anthropic principle?
Well, weak- anthropic beats the hell out of strong- anthropic. One cannot, in good conscience, postulate God from the improbability of a good primordial soup kitchen, when beating the odds is the prerequisite for anything evolving sufficiently to be amazed. Life, however, plays hell with probability, because it’s possible for an improbably complex thing to create as many improbably complex things as energy allows. Introduce evolution, crank out a tool user, it gets worse. One dedicated farmer can create a vast and profoundly improbable flourishing of life. Now if we move out into the universe and find a vast and improbable flourishing, we will have cause to suspect the existence of cosmic farmers. This especially because it appears we are evolving towards that state ourselves. Dressing up this concept in pseudo science though, strikes me as a bit pretentious. Which is my take on Louis Crane's idea of meduso-anthropic principle

Q:What measures should be taken to make tower cranes stable?
The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3 times of the same structure light steel wire rope (laboratory comparable conditions), not easy to wear and corrosion is not easy to cause the service life of wire rope large amplitude extension. Manganese phosphating is wear resistant phosphating, which can solve the wear problem in the use of wire rope and improve the corrosion resistance. It is for reference only
