It has been a very boring day today…
Though I wanted it to be constructive, I find very less to do.

Whenever I feel I have nothing to do, I resort to reading books… But alas, I have not yet accustomed to reading e-books. I find the paper books more convenient and healthy (to the eye).

So, just sat googling for some books based on topics. Though I wasn’t actually reading any book, I was skimming thru the synopsis part of the books that I found interesting.

Really, I should say, it had been a good learning experience. I hadn’t done such e-book browsing before, but I find lotsa interesting things out there…

For example, I’m interested in puzzles and riddles. I found a book called “Riddles of the Sphinx and other mathematical puzzles” by Martin Gartner. Just went thru the first riddle in which he had created a shape (a quadrilateral basically) which is formed by 4 small replicas of itself (he has named them rep-tiles). Riddle will be to divide a shape into 4 equal sized bits of the same shape…

While looking at the solution, at the end there would be another question which gives a puzzle for a simiar pentagonal shape…
At the end of second solution, he’ll again pose a question to imagine that rep-tile as living, and it multiplies itself in 1 min to form a bigger tile, which in turn replicate the next minute to form a bigger-bigger tile, and it goes on. How much bigger tile would result after 15 min, if the first bit has an area of 1mm2.

Might be I’m a bit too much here :), but I like such puzzles…

Looking forward to read many more such riddles, and become a riddler myself (is there any one out there ready to beat me? literally :) )
