Mathematical gift wrapping [video]
- deckar01 11y agoI wrapped some presents last night that did not turn out great. Measuring the paper to minimize overlap makes a pretty big aesthetic difference.
- LoSboccacc 11y agohere's the real hard one, the cylinder, wrap it around like this aaaaaaaand skip! we'll never know how to close cylinders sides I guess (ok isn't hard but annoying as hell https://youtu.be/dH_gpSfaA6E?t=1m55s https://youtu.be/dH_gpSfaA6E?t=1m55s )
- chestervonwinch 11y agoNeat. I wonder how this problem could be better posed mathematically. Minimize both the number of folds and surface area of wrapping used subject to the constraint the surface of the gift is completely covered? Yikes. It seems like predicting how a fold in the wrapping would affect the available wrapping left to cover the gift would be difficult.
- frogpelt 11y agoI imagine you could get more usage out of a roll of wrapping paper if you could minimize any paper overlap. But it would take for more time to cut the paper.
- Someone 11y agoThat would be a research subject in the mathematics of origami. That field is fairly advanced (See for example http://www.langorigami.com/science/science.php http://www.langorigami.com/science/science.php), but I am not aware of people studying 'boxes'.
- strttn 11y agoI'm always really impressed by the "Japanese" diagonal wrapping technique.
