It turns out that decorating your Christmas tree isn't necessarily all about taste. Mathematicians at the University of Sheffield in the UK have developed a formula for the perfect way to deck the halls. More specifically, what ratio of ornaments to lights to tinsel will make your tree most aesthetically pleasing.


Since the geniuses behind the formula hail from the UK and embrace that new-fangled metric system, you'll need to know the height of your tree in centimeters. But you're just a tape measure away from having the data you need to use their handy online calculator. Did you know your average six foot tree only needs 37 ornaments to look its best? And here Hallmark has been telling us to cover every last patch of green with tiny versions of Darth Vader and Spock. [The University of Sheffield via PhysOrg]
