The passage discusses the challenges faced by compilers due to the rapid increase in data, emphasizing the importance of including measurement methods in tables and graphs. It expresses disappointment that the supplement to the compilation, which includes data from various sources, was not included in the current publication. The supplement is noted as invaluable for those interested in atomic energy. The review concludes by praising the well-presented compilation as essential for anyone working with neutrons and looking forward to future editions. The second part introduces a textbook on theoretical statistics by Prof. Paul G. Hool, highlighting its revised and improved second edition. The book is praised for its fresh and clear treatment of essential statistical concepts, suitable for first-year students with a background in deductive logic. The reviewer suggests improvements in terminology and additional content on algebra and generating functions.
