Contact – Carl Sagan and pi

My previous musings about xkcd finally let me to read their whole archive … which means that I eventually found this one, which is possibly one of my favorites.

Got me thinking about Carl Sagan‘s novel, Contact.  Loved the book.  Film was ok, but I was really disappointed that the bit about pi never made it in.

Whilst browsing wikipedia about this subject, found a link to http://www.pisearch.de.vu/ (currently unavailable though).  Struck me that this would be a good way to collect personal details about people (‘try it with your credit card number’ 🙂

Further browsing has turned up Pi-Search, which you can use to look for sequences in the first 200 million digits of pi.  Did you know that the sequence 12345678 occurs at position 186,557,266?  Well now you do.

The Feynman Point is also interesting.  Maybe one day, I’ll give both Richard Feynman and Pi an entry of their own.
