Empirical Reality from the Horse's Mouth
on 19 August 2017
When physicists insist on writing nonsense, it is helpful to get it from the horse's mouth, so to speak. With relativity we have to get our heads around the idea that no matter how fast we are moving, we will always measure the speed of light relative to ourselves as exactly the same. This defies the common sense of our daily experience. But, using everyday language and practically no mathematics, Einstein leads us to accept this experimentally confirmed truth in the only way it can be accepted: that our time and our space lengthen or shorten such that the light around us travels at 300,000 of our km per one of our seconds. OK. I'm sure he's right. But, he does another thing in this book which I found most valuable, and that is that he firmly ties the discussion of relativity to empirical reality, so that in the end we might accept relativity with no more fuss than we accept a 30 cm rule for measuring distances and drawing straight lines. One returns to the undergraduate texts much strengthened.
