Somewhere out there a tortilla maker is striving to make a perfect Cardioid Tortilla.
But there is still work to do.

Math Quiz: NYT Learning Network
Through Math for America, I am part of an on-going collaboration with the New York Times Learning Network. My latest contribution, a Test Yourself quiz-question, can be found here:

This question focuses on the increasing number of Americans who are collecting Social Security early. What hourly wage is equivalent to collecting social security benefits?
Application Technology
Ancient Lego Robotics
The antikythera machine is commonly referred to as the “world’s oldest computer”. Dating back to around 150 B.C., the mechanism was discovered in a shipwreck around 1900, and it has amazed scientists and engineers with its precision craftsmanship. Recent x-ray analyses of the object helped bolster the conclusion that it was designed to predict eclipses, and probably was able to do so with remarkable accuracy.
What could be more amazing than a 2000 year old computer? Perhaps this working replica of it, made entirely out of legos.

This video shows the functioning lego replica and gives some of the mathematical background relevant to how the machine operates (apparently the ratio 5/19 is extremely important for calculating the cycles of ellipses) . Throughout the video, the machine is deconsrtucted and you can see the inner-workings of the various parts. Truly amazing.

There are probably a lot of things in this world that could use a Minus 10 button.
