Molecular Origami: Precision Scale Models from PaperUniversity Science Books, 1995. gada 22. maijs - 223 lappuses This is a fun, hands-on guide to understanding the basic structure and chemistry of matter. Drawing on the Japanese art of paperfolding, the book provides rip-out patterns for 124 molecules, along with easy instructions for folding them into scale models, many of which are three-dimensional. The molecules progress from simple ones like methane to more exotic structures such as quartz and buckminsterfullerenes. Questions and discussions are included. "Who will use this book? Any chemist who is young at heart might like to snip, fold, and glue, and in doing so might well come away with a deeper knowledge of the bricks of their trade. Any teacher should be able to use them as an aid to teaching, at all levels ... Anything that renders chemistry less abstract, more tangible, is to be welcomed, and this unassuming, engaging publication deserves to be well received." P. W. Atkins, THES |
