I would have bought the book preorder, finally pushed up. See science as if some familiar friends and happy to chat. The book and the year before that in this Lost
the Math regarded as a question and answer it. Mathematics gives the revelation or miracles, only personal experience to personal experience, make it sound like a bit of metaphysics or religion, and here I mainly want to say is to enhance the force of a way of thinking. In addition to obtaining a reading outside of the main objectives is to enhance the knowledge power of thinking, my feeling is that reading books and literature in physics of the time when the role of mathematics in play behind the lifting force of thinking. Because mathematics into physics of the process is a grueling process, continue to practice the skill growth. Done to prepare handouts ready late, go back and read the first chapter, when to sleep. Author is very interesting, he was a graduate student in quantum field theory of the most successful of that era, that time he was convinced that guided the development of experimental physics rely, for the behavior of mathematical obsession miracles viewed as a pagan. This is referred to in his later years Einstein different way. Of course, we can say that Einstein wanted ahead of its time, but no more than to go. Later physical development allows authors recognize the leading role of mathematics in the physical development of the theory, the last paragraph quoted Nima completely, then the universe is the language of mathematics. A very interesting gossip, the first mention of Newton, he published as "natural philosophy" of his fame, when a 45-year-old bachelor. That era, there is no clear scientific or physical concepts, Newton's motivation is very simple, he wants a more accurate understanding and exposition of God, which is very cute for their own goal, to create a full field, from this point, Newton's physics is indeed the founder.
Prepare handouts when they re-read it again fundamental part of string theory, there are some new understanding, because for me this year CFT deeper understanding of it.
With expectations will always be some lost, and loss expectations are not wrong, a little child can understand a little Europe, because at that time she might expect too much of it, so the loss of the more deep. However, to keep looking for each other, is a healthy love it.
Today's arXiv ps lectures on 2 + 1 D duality looks very interesting.
