Is this product review positive? Title: The original guide on path integrals. Review: This is an outstanding book for those who seek i) an intuitive understanding of quantum mechanics (QM) and quantum electrodynamics (QED); or ii) a guide on the Feynman path integral method. Within either of these contexts, the text and derivations are crystal clear and highly pedagogic.If what you are looking for is a complete, thorough course on QM or QED, this book should not be taken as a standalone text. It has to be used in conjunction with another appropriate textbook. For example, I use this book together with Rodberg and Thaler's book on quantum scattering theory for both research and teaching on scattering theory. Other textbooks would be applicable to other purposes. Answer:

Is this product review positive? Title: Tungsten E2 won't turn on Review: There is a problem with the E2, after some time, for me it was 6 months, it just stops working. No matter what type of reset you perform the unit will not turn on. Leave the unit for a week or disconnect the battery and something resets and it starts working again. There are many people having the exact same problem, however Palm takes no responsibility for this defect and blames the problem on 3rd Party Apps. I have an extended warranty but I am waiting for the E2 to be obsolete before I act on it, I don't want my unit replaced with another defective unit. It's a good pda for the money, when it works it does what it is supposed to do. Until this defect is fixed I would not recommend the E2. And since I have been disappointed by Palms customer support I cannot recommend any of their products. Answer:
