The Trouble with Physics...and What Comes Next came out a year ago (September 2006) and occasioned controversy. What's your view on this? Is the controversy over? If not, how is it going? Is it a good or bad thing for the physics profession? Does it annoy you? Has anything changed as a result of discussion? On a quantitative level, what do you predict the Smolin/String ratio will be a month from now---say noon Pacific time on 1 October? Today when I happened to check the ratio was 6.2. That is the Smolin book's Amazon salesrank was 1603 and the average salesrank of the five most popular string books was 9942.4. In case anyone is interested, the five bestselling string books, when I checked at 3 PM this afternoon, were Greene fabric Randall warped Greene elegant Steinhardt endless universe Kaku parallel worlds (except for the Steinhardt, I assume everyone is familiar with the titles.) The ratio 9942.4/1603 is 6.2. In other words judging by salesranks, the Smolin book was selling around 6 times better than the five most popular string books' average. This is one measure of how the controversy is going---there are other measures we could use. What is your forecast of what this same ratio will be on 1 October, one month from now? This is a kind of reality check to gauge your understanding of the controversy, and to discover who the good guessers are. I will post some other readings of this ratio over the next few days to see if they show any trend. BTW I think the ratio today was boosted by the fact that it is the beginning of the college semester and university students are buying their books. By October that may not be such a factor. Can you suggest any other indices of how things are going, stringwise, that we could look at?
