Yes, I'll squeeze in one more bit about Martin Gardner before his day of honor tomorrow (to any who are tired of hearing about Martin Gardner by now, I apologize, but HEY! it's MY blog so deal with it ;-))

When Gardner's "

**The Colossal Book of Mathematics**" came out in 2001, I looked at its size, price, and the many chapters covering topics I wasn't particularly interested in, and ignored it (I already had plenty of Gardner books on my shelf). It was only years later that I checked it out from a public library and discovered not only how many chapters were of great interest to me, but also how many of the topics I wouldn't normally have found interesting were made so by Gardner's deft and insightful writing.

So again I highly recommend this volume to anyone lacking it on their shelves. If you're ever stranded on a desert island it would offer you weeks/months of mental entertainment (...and, as an alternative, just in case I got tired of math, I might take along Gardner's essay-anthology, "

**The Night Is Large**," as well!).

Meanwhile, 'Mathematics Rising' blog has just covered the 3rd of my 'Fab Four,' Bernhard Riemann, here:

Finally, a couple of recent math blog carnivals here for your enjoyment and delectation:

And I'll end today with a factoid lifted off an old Twitter posting

**:**

A 10,000

*number gap*in prime numbers: 9973! + 2 through 9973! + 10006 are all composite (non-prime).

...someone please double-check those for me over the lunch hour and get back to me to confirm.

Am I wrong, or _The Colossal Book of Mathematics_ is a collection of chapters from the column he had on Scientific American? If so, and since I am not stranded on a desert island and have at disposal all 15 books (in paper and pdf) I won't care for it :-)

You're correct, EXCEPT, that the book has wonderful addenda/updates and letters added that were not part of the magazine.
