Was there a beginning of time? Could time run backwards? Is the universe infinite or does it have boundaries? A Brief History of Time will tell you the truth. A Brief History of Time is a great book by Professor Stephen Hawking, the world's most famous physicist, black hole theory and the "Big Bang" theory’s creator. It is a good book of modern theoretical physics. You can get an outline of our knowledge currently about gravitation, time, big bang and so on. I still cannot believe this is written by the most gifted scientist for general public. Using simple language, Stephen illustrated a full picture of what the universe is and what time is, within the bundary of human beings current understanding. Never imagine pure theratic physics could be so interesting and easy to understand, although I have to admit that I only understand 40% of what he is saying. After reading the book, I felt strongly pessimistic with the further advancement of theoretical physics. It is, in my opinion, quite a dead-end job. Any newly proposed physical theory 暑期读书笔记&影视剧点评精选读书笔记影视剧点评书评舞台艺术点评读后感 need to be in good accordance with experimental observation to be proved and publicly accepted. Theoretical physics focuses on the extremes -- the lightest particle, the earliest stage of the universe, etc. According to Hawking, we human being were not able to produce the required extreme conditions to test the new theories. Therefore we were not able to prove the authenticity of them, thus not able to advance. Prof. Hawking wrote the book in 1988. Twenty-two years later, we regrettably find that the improvement in experimental methods and equipments in the area of particle and cosmo- physics is trivial compared to what is really needed. But you should not go for understanding everything inside the book because the physics require proper math formulae for complete understanding. I can't understand "uncertainty principle". I think particles' position and velocity are fixed in a way that we are not recognized now. However, I agree with following opinion: 1, There is no single formulation of the fundamental theory. 2, The whole collection of different formulations could be regarded as a complete unified theory. As an unfortunately result of the theories not being able to be proved, or falsified, a whole lot of different theories, all interwoven with indecipherable mathematics burgeon. To catch up with the "state-of-the-art", a new theoretical physicist has to study the majority of these theories, and the very bespoke mathematics attached to each of them. In my opinion, the process would be very exhausting, and unworthy, since most of the theories will be proven completely nonsense. I believe the difficulty and boringness will not stop a small group of very ambitious people from pursuing, in the hope their home-made theory would someday equate the status of that of Newton's and Einstein's today. I personally would not be willing to see my child become one of them.
