### Jim Rubillo Receives Lifetime Achievement Award

Jim Rubillo has been a member of the National Council of Teachers of Mathematic (NCTM) for more than 1.4 billion seconds. For his four decades of service to improve mathematics education, he received a Lifetime Achievement Award at the 2013 NCTM Annual Meeting.

Jim was the Executive Director of NCTM from 2001 to 2009, and he was my supervisor for the last five of those years. But he was more than just my boss — he was also a mentor, friend, and problem-solving companion. So when Ann Lawrence, chair of the Mathematics Education Trust, called to ask me to prepare a tribute video for Jim’s award ceremony, I was honored by the request.

I didn’t want to prepare a talking head video — I have a face for radio — yet I don’t have access to elaborate film equipment. Consequently, I opted to create a PowerPoint presentation with narration, which I then uploaded to authorSTREAM. Here it is, for your viewing pleasure.

Prior to its showing at the awards ceremony, Ann Lawrence mentioned that the tribute video had been created by me. Upon hearing this, Jim murmured, “Oh, no…” (Truth be told, I think I was rather kind.)

One of the many reasons that I loved working with Jim is that he always had a good math problem at the ready. He shared more problems with me than I can count, but here are two of my favorites:

- What percent of the numbers in Pascal’s Triangle are even?
- Many years ago, it was believed that the Earth was the center of the cosmos. This was a reasonable hypothesis — it appears that the Sun rotates around the Earth. But if Earth were the center of the solar system (instead of the Sun), and if Mars rotated about the Earth, what would it have appeared that the path of Mars was?

Both of these problems have non-obvious answers, which is a trademark of the problems that Jim likes to share. Jim often looks at things with a unique perspective, and he willingly talks math with anyone who’s willing to listen. Consequently, Jim was an exceptional choice for this award, and I’m proud to call this lifetime achiever my friend.

### Fishin’ for an April Fools Math Joke

My friend and former boss Jim Rubillo sent me the following email last night:

I am cleaning, and I found this book that you might want:

One Million Random Numbers in Ascending Order. Do you want it, or should I throw it away?

Seemed like an odd book, and I thought he might have gotten the title wrong since RAND Corporation published *A Million Random Digits with 100,000 Normal Deviates* in 1955. (Incidentally, you should visit that book’s page on www.amazon.com, where you’ll find many fantastic reviews, such as, “Once you’ve read it from start to finish, you can go back and read it in a different order, and it will make just as much sense as your original read!” from Bob the Frog, and, “…with so many terrific random digits, it’s a shame they didn’t sort them, to make it easier to find the one you’re looking for,” from A Curious Reader.)

Knowing that Jim is a stats guy, it seemed plausible. A little confused, I wrote back:

Is it literally just a list of random numbers? If so, I’ll pass. But if there’s something more interesting about it, then maybe?

His response?

It’s a sequel to

The Complete Book of Even Primes.

Gotcha!

And so it goes, with April Fools even afflicting the math jokes world.

Thank goodness he didn’t tape a fish to my back.
