This outstanding book, or some book with the same level of original ideas, might have substituted, long time ago, texts like Halliday and Resnick. Shame on us, Physics teachers, for we are so conservative and narrow-minded. Nothing against Halliday and Resnick's - it is a very good and well written book - but we should try to be more open to the difference. L.N. Cooper, a Nobel Prize in Physics, condensed in this relatively small book all the essential ideas of general Physics. The book also includes a set of problems. Many of the problems are "easy": they are for ideas, not brain gymnastics. In other words: they were not prepared for the market of qualifying examinations. Again, nothing against qualifying exams, but qualifying exams are not science. Sometimes I think my ideas are only reflecting the fact that I am from an underdeveloped country, but it is a shame that a book of this kind is now out of print !
