Friday Math Movie - Google Tricks, Hacks and Easter Eggs

By Murray Bourne, 21 Mar 2008

OK, so it's Easter.

Easter is a 'movable feast'. It always falls on a Sunday somewhere between March 22 and April 25. Its date is generally agreed to be the first Sunday after the first full moon on or after March 21.

There is a lot of interesting mathematics arising out of Easter dates. For example, the date of Easter is supposed to repeat after "exactly 5,700,000 years" according to this Wikipedia article. There are calls for reform on the date of Easter since not everyone agrees on the date.

On to the movie which admittedly has only a little bit about Easter and not much about math 🙂 .

This week's movie contains some fun stuff you can do with Google. The math comes towards the end, when we find that Google has a mathematical solution for the greatest mystery of life - and the universe. It uses Google's calculator function.

    42 = the answer to the ultimate question to life, universe and everything - is straight from Hitchhikers guide to the Galaxy.

    Yeh - I wrote about this value before, in my Summary Review of the Hitchhikers' Guide movie.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
