A tale of three cultures? Some guys in the UK claim to have developed a formula for perfectly decorating the Xmas tree, lights, tinsel, ornaments, and angel or star based on the height of the tree. This article was published by Gizmodo Australia. As Australia is metric, I would expect them to appreciate that the formula is based on the tree's height in centimeters. But the author goes off in this strange rant about metric. I assume he might be American and this was originally published in the US. http://www.gizmodo.com.au/2012/12/the-mathematical-formula-for-the-perfectly-decorated-christmas-tree/ "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 centimetres." The comments section doesn't seem to appreciate his lack of love for metric. Oddly, no one comments on the formulas. The tree seems seriously under-decorated to me. Also, I would expect the formulas to consider the breadth of the tree at the bottom, and depend on the surface area of a cone approximating the tree
