You're right, Dr. Bill--this was very interesting. Dr. Lienhard, eh? Wonder who he liens on? Ah, har, har, har...
At first I thought it was a nice touch of humor that he had {theme music} at the end of the talk; then I remembered that there's an audio version. Shoot, woulda been nice. Anyway--I liked his final note: Bibliophiles might prefer that I had introduced the old Latin word codex for the first books. I'll excuse myself on the basis that the Germanic word "book" is more elegant. It traces back to the Gothic word boka, which means a letter of the alphabet. Codex literally means the trunk of a tree or a block of wood.
I don't think I knew that the Turks gave us books. Thank you.
