Query: I gave it to my professor

I was in awe of the book when I read it. But to be honest it was the title that enticed me to read it. I was refferd to it by books on chaos theory and cosmology. The manner in which Hofstadter approaches the complex idea of looped systems is what impressed me the most. Not "being good in maths" and the like is simply no excuse for one not to at least attempt to read the book. Beware! Read it during the day most certainly not for bed-time reading!
