Ex Input:
Great Book For Interested Physics Students . When reading books about Chemistry or Physics, the level of depth is usually to the electron, proton, neutron, and there is usually some mention of quarks and antimatter and dark matter, but with no explanation of where these ideas are coming from. This book gives a good, nonmathematical description of the Standard Theory (Model) of particle physics, which gives a good account of what particles are known, how forces are treated using particles called Bosons. The books will answer any questions about what is known, but without proofs. I plan to study physics as an undergrad, and probably grad too, and have always been attracted to learning about the fundamental particles. This book was very satisfying for me, and will be for other interested students. Kane provides information about not only the standard theory, but also the facilities where research is done, where the field is going, and what a future student can expect. A quick read and definitely worth the time

Ex Output:
POS

Ex Input:
Run from the fork! Run from the Fork! . How many pages should a writer fill to explain that a character is afraid of forks, knives and mirrors? Two? Well Koontz takes over a hundred, and repeats, repeats, repeats. 500 pages should have been cut from this book. Repetition weakens writing

Ex Output:
NEG

Ex Input:
