Oceanographers, astronomers, mathematicians, biologists, geologists, psychologists, and experts in other - sometimes quite arcane - fields, contributed to this collection of lucid answers to puzzling questions. The questions were asked by lay readers of Scientific American; the responses address the true strength of a spider's silken dragline, carsickness, tooth decay, whisker specialisation, and tonnes of other questions. With questions on one side and answers on the other, these 48 fact-filled cards are a great source of condensed information - all in a deck the size of a pack of playing cards! Discover emergent theories and intriguing facts in this concise, stimulating compilation.
Cards are approx. 8.3cm x 10cm .
