Hilbert's Place (Not to be confused with Hilbert Space)

Hilbert's Happy Day - bilingual edition - is currently the number one best selling book on Amazon!


Ok, so he's only number one in non-Euclidian geometry, but WOW, my Hilbert is outselling David Hilbert.  Of course, why anyone would pay $2.99 for a Kindle version of Hilbert's Foundations of Geometry when it's available in pdf on Gutenberg is an interesting question.

Of course, why anyone would pay 99 cents for Hilbert's Happy Day when it's available for free at least one Wednesday a month is another interesting question.  Two down, 21 more to go!

That crazy old lady with the rat terries


I was walking the dogs this morning.  It is cicada season and the storm last night knocked several from the trees and down onto the ground. 

Shoebert loves cicadas.  Every walk is like an Easter egg hunt this time of year.  Cicadas live most of their lives underground – seven years or more!  When they finally craw to the surface they have developed a shell covering a winged body.  They then hatch out of these shells, unroll their wings and mate.   Then they die.

Once the cicada is dead, it starts to give off an odor that Shoebert can smell from several feet away.  The fresh or dying ones, however, he often doesn’t notice, even when he walks right past one on the sidewalk.  Today there were several fresh cicadas on the sidewalk.

We were only a few houses down when he went right past a cicada that was lying on the edge of the sidewalk.  I stopped, tapped my foot next to it and said to Shoebert, “here’s one!”  He turned around, put his nose to the ground and started searching.  Depending on where he was I would say “you’re getting colder.  Warmer.  Warmer. Hot.”  The closer he got to the cicada the more excitement I put in my voice.  Finally, I was nearly yelling, “Hot.  Very HOT.  SPONTANIOUS CONBUSTION.  YOU GOT IT!”

I looked up to see a neighbor across the road who was loading lumber into his pickup.  He was standing still, his mouth slightly opened staring at me.  I smiled sheepishly and gave him a weak way from my wrist.  He closed his mouth and raised his eyebrows while nodding.  Then he quickly went back to loading the truck.

On the way back home at the end of the walk the neighbor was returning.  This time I gave him a full wave.  He smiled and waved back.  He may think I’m crazy, but harmless.  Just like Shoebert.
