# John Baez's Favorite Numbers

I've started my day with a new respect for the divergent series.

247 and 248 are both dimmed by the enormous halo surrounding 256. You can't get a good number with 20 of that thing.

What.

Albert Baez was also a physicist, father to Joan Baez and Mimi Fariña, and uncle to John.

He lost me at "quasiperiodic planar patterns with pentagonal symmetry of a statistical nature"

John Baez is actually a cousin (or something like that) of Joan Baez, and a math-physicist at UC Riverside. His 'This Week's Finds in Mathematical Physics' blog/column overflows with intersting things...

null terminated : do read the pdf slides of the 24 talk. Baez sketches out a brief history of Euler's approach and Édouard Lucas's challenge.

Here's a page on the challenge from Baez's column.

*If you're a mathematician doing a calculation and you get the answer 248, it means something completely different than if you get 247 — because the number 248 shows up in all sorts of amazing places, while 247 is just dull.*

247 and 248 are both dimmed by the enormous halo surrounding 256. You can't get a good number with 20 of that thing.

*One of the first hints of this fact was Euler's bizarre "proof" that*

1 + 2 + 3 + 4 + … = -1/12

which he obtained before Abel declared that "divergent series are the invention of the devil". Euler's formula can now be understood rigorously in terms of the Riemann zeta function, and in physics it explains why bosonic strings work best in 26=24+2 dimensions.

That's a "what" of "I need to know more about this formula and it's rigor" not a "what" of "lolmathclassishard".

The one thing that has proven to be most frustrating in studying any mathematics is the fact that Euler is pronounced like 'oiler.' This gets more interesting given the fact that I love Hockey, and imagining the very possibility that a team from Edmonton could be called the Eulers.

Pretty much every math department softball team in history has been called "the fighting Eulers."

The Fighting Galoises always manage to get get into a brawl and fall apart after a few great first innings. The Commuting Abels are all switch-hitters. The Gaussians though will fucking clean your clock every which way.

i too like 8. but i think it was in relation to 'herbie the lovebug' movie growing up.

I hate eight. Eight sucks. I have always hated eight. The only thing I like about eight is that I really enjoy writing it in the two-stacked-circles style.

I like six! Six is one of my favorites. It is a perfect number and a triangular number and it is the number of legs on a bee and it is the number of my favorite Final Fantasy game.

Actually, maybe I'll reconsider eight, because it is my shoe size and a good number of slices for a pizza, and I like octopi, though I have never liked spiders. I am also not a fan of octagons, except that's where they have UFC fights, and I find that amusing. So eight is okay after all.

I have very little understanding of what John Baez is talking about, but I'll credit him with teaching me to like eight anyway.

I only went through the first batch of slides and my mind is already blown. That last continued fraction equation makes me want to read a continued fractions textbook, and I forget the last time I experienced that sensation. Thank you John Baez and thank you vostok. I am going to take a short rest before I have a go at the second batch of slides.

Actually, the most frustrating thing about pronunciation of mathematicians is that Euler is pronounced "Oiler" but Euclid isn't pronounced "Oiclid".

Monstrous Moonshine. I have a good book on number theory that I need to spend a few months trying to understand before I can figure out where to start understanding it.

There's probably another step or two in there before I can start understanding what's going on. Let's go shopping.
