The name 'Thoughtings' was inspired by a 5-year old who, when asked to explain what thinking is without using the word 'think' said 'It's when you're thoughting'. Children love pondering big philosophical questions like 'Does the universe end?', 'Where is my mind?' and 'Can something be true and false at the same time?'. These verses capture that impulse in the growing mind and feed it further. These are not poems or, at least, not in the traditional sense of the word... They are a kind of poem specifically designed around a particular puzzle or problem that might be thought more philosophy than poetry. Here's to the joy of puzzlement!

Fun-filled, math-based puzzles include Elephants and Castles, Trianglized Kangaroo, Honest Dice and Logic Dice, Mind-reading Powers, and dozens more. Complete solutions explain the mathematical realities behind the fantastic-sounding challenges.

This sharply intelligent, consistently provocative book takes the reader on an astonishing, thought-provoking voyage into the realm of delightful uncertainty--a world of paradox in which logical argument leads to contradiction and common sense is seemingly rendered irrelevant.
