切蛋糕的最佳方式 伦敦一名数学家在YouTube视频中展示了最佳的切蛋糕方式。您别说,还真有那么点道理。 Forget everything you know about cake cutting; this new method could turn the seemingly straight-forward practice on its head. Although, using the word 'new' isn't accurate, because the method is actually a 100-year-old trick unearthed(发掘,破获)by London-based author and mathematician Alex Bellos. In his latest YouTube video, Bellos describes how taking wedges out of cakes leaves them susceptible to drying - and we should instead be cutting them in lines so the whole cake can be sealed and stored. Known on YouTube as Numberphile, Bellos first explained the problems with modern methods of cutting cakes. Namely, he said that if a wedge(楔子) is taken out of a cake but the rest of the food is then stored in the fridge, the edges of the cake open to the air will be 'dry and horrible', Bellos says. 'You're not maximising the amount of gastronomic(烹饪学的) pleasure that you can make from this cake.' There is instead, he explained, a better way of cutting cakes that dates back more than a century. The method was first published in Nature on 20 December 1906 in the letters to the editor section by English mathematical scientist Francis Galton. Titled 'Cutting a round cake on scientific principles', Galton's letter explained how the 'ordinary method of cutting out a wedge is very faulty'. |
