Mathematics Carnival 51
By Murray Bourne, 24 Apr 2009
Welcome to the 51st Carnival of Mathematics.
After a not-so-short hiatus (6 weeks of deadly silence), I’m happy to present Math Carnival #51, aka “The Resurrection Carnival”.
Random bits of trivia about 51 throughout history:
- The year 51 (AD, or CE) in the Julian calendar shared one thing in common with today’s Carnival — it’s start date was a Friday.
- In the Gregorian calendar, 1751 also started on a Friday.
- Euler published his theory of logarithms of complex numbers in 1751.
- There is no truth to the rumor that this carnival disappeared for some time because the coordinator, Alon Levy, got lost in Area 51.
On with the show.
In Aspects Of A Topic, Vlorbik on Math Ed argues the case for considering the formula for the length of a curve parametrically, rather than the normal asymmetric definition .

Beginnings and Endings
Inspired by Benford’s Law and Pat’s article, I did a quick google to see how many search results appeared for various numbers, and came up with:
Indeed, the number of results decreases until 9, but there is an upset for 10:
Massively Collaborative Mathematics
Jason Dyer gives a “simple as possible” overview of Timothy Gowers’ initiatives in A gentle introduction to the Polymath project. The post gives the background to the density Hales-Jewett problem. The line that caught my eye was from Gowers: “Is massively collaborative mathematics possible?”.

An interesting coincidence occurred with the following 2 posts. Both talk about stacking spheres in square pyramids, but in quite different contexts.
Free Math Downloads
My contribution to this Math Carnival is the post Free math software downloads, which may come in handy in these tight economic times.
Future of the Math Carnival
I’m not sure where the Carnival goes from here. There seems to have been a slide in interest in recent months.
My proposal: Why not draw up a schedule so that we host once every (say) 4 months? Would that work, do you think?
That concludes this edition. Goodnight and good luck.
