DailyDirt: Is It Really That Hard To Cut A Cake?

from the urls-we-dig-up dept

Life is filled with small problems. Some more important than others. Mathematicians have attempted to solve some of these conundrums, and apparently one somewhat popular task is cutting things up. Here are just a few (useful?) examples of math applied to the task of cutting a cake. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!)

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    The cake cutting thing is BS.

    The cake cutting thing is BS. Think loaf of bread. How well would cutting it both ways down the middle keep a loaf fresh? Not at all. You are better off slicing off one end. Same goes for taking a single wedge of cake, which leaves only a *single* face open. Squishing the cake sides back is of dubious value and efficacy at best.

    Cutting a cake manually is so hard! What we really need is a 'smart' knife that will go on the net and look up the best way to cut each cake, then monitor the depth of the cut and the pressure being exerted so that we can know we're doing it right. It also needs to interface with the smart refrigerator so that it can look up the perfect proportion of milk to go with each slice. Also, the cake needs to be sitting on a smart plate so that it can tell how much is left and order another from the store.

    i think i saw a cake in a hollywood movie once, so either way it's illegal to cut your own cake

    I imagine there is an existing method patent on the cutting of cake, is the one for cutting cheese?

    My preferred method of cake preservation is to press a piece of plastic wrap against the exposed surfaces. No drying out, and it's a lot less hassle than this cutting method.

    Also... who keeps a cake in the fridge?? Refrigerated cake is the worst.
