DISCLAIMERS:

A while back, I thought it would be neat to learn the mathematical constant Pi, one digit a day, for an entire year - so by the end of the year, I would have 365 digits memorized. To make a long story short, I have a Pi trainer app and can punch in about 650 digits without making an error. My ability to recite is probably somewhat less than that, because some of the memorization in using the Pi trainer is that "muscle memory" helps my fingers know which digit to select next.

There is a point in the random sequence of Pi, which starts at digit 762 (after the decimal place), with a series of 6 consecutive 9s. This is known as the Feynman point, after some guy who thought it would be cool to learn Pi to this spot.

Since I want to be cool like Feynman, I wanted to find the next-closest sequence of 6 digits in a row. I wasn't particular - I would've settled for 6 3s or 6 8s - but it turns out, the next such sequence is also 9s. It is also over 193,000 digits deep - so I have abandoned this quest (considering the official world record for Pi memorization is only about 70,000 digits).

Anyway, as a result of my aforementioned quest, I found a site (http://angio.net/pi) where you can search for a string within the first 200 million (200,000,000) digits of Pi...which in turn led me to find the Project Euler website. This site presents a bunch of fun (*see disclaimer) problems that can be solved using math and computer programming skills. After discovering the site last night, I spent a few hours solving the first few problems, and stayed up way too late. At any rate, so far I have been able to use Microsoft Excel to solve the first 9 problems (I have a macro running as I type which will help to solve problem 10), but I anticipate using some of my limited programming skills to solve some of the more challenging problems. I think it will definitely enhance my problem-solving and computer programming skills.

Just thought I'd pass along, because I know there are a few others who are into math and computer programming. Enjoy!

- The term "Fun" in the subject of this thread is highly subjective. For instance, my wife rolls her eyes every time I talk about any of the topics I'm about to present. Read at your own risk.

- This is going to be somewhat of a ramble. I apologize, but I promise...there is a point to all of this.
