Eigenvalues produce billionaires

By Murray Bourne, 08 Jul 2009

Did you know that Google's excellent search ability is based on eigenvectors of a matrix?

Here are some interesting articles on how Google works and how it all depends on matrices.

How Google Finds Your Needle in the Web's Haystack (for background)

The Anatomy of a Large-Scale Hypertextual Web Search Engine (the original article by Sergey Brin and Larry Page when they were students at Stanford, before becoming multi-billionaires.)

    I like to propose the manufacture of large dimension 8x6 inches of QR reader. Recently many newspapers (e.g Asbury Park Press )is inserting QR ads. The problem is that one must have expensive phone to read them. Could you approach an AMERICAN manufacturer and suggest the production of such device?. It must be large ( the phone reader is extremely small) and it is very hard on the eyes..Also the price must be reasonable.You could use such a device for teaching anything. There is no limit to the possibilities.

    Interesting idea, Adam. Anyone up for it?

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.
