The Mathematics of Gift Wrapping

Has this ever happened to you?

NotEnough

You place a gift on the wrapping paper. You estimate how much you’ll need. You cut. You place the gift on the paper. You fold over both sides.

Crap.

That’s when you realize your estimation skills are on par with those of a government contractor.

But, no worries! Math is here!

The hypotenuse of a right triangle is longer than either leg. Consequently, turning the wrapping paper at an angle will allow the paper to cover the gift.

Rewrapped

My wife hates it, but whatever! What initially appeared to be a terrible estimate yielded a 15.8% savings in wrapping paper.

Based on my calculations, if all gifts were wrapped this way, the country would save $147 million each year on wrapping-paper related expenses. (Where’s that statistic when politicians discuss the economy?)

Mathiest Week of 2013

Can you hear it? That’s the sound of the awesomeness approaching.

May 2013

It starts this Wednesday.

5/8/13

The month, date and year are consecutive terms in the Fibonacci sequence.

It continues on Thursday.

5/9/13

The numbers form an arithmetic sequence.

And then there’s Sunday.

5/12/13

That’s a Pythagorean triple.

Arithmetic sequence dates are a dime a dozen. In fact, there are six of them in 2013 alone. Pythagorean dates and Fibonacci dates are far more rare. There are only eight Pythagorean dates and six Fibonacci dates in the entire 21st century. To have all of them occur within a six-day span is incredible.

How will you celebrate?
