Journal Entry 1 by Bhuri from Boston, Massachusetts USA on Tuesday, August 10, 2010
To begin, an excerpt from the wiki entry for the "Laffer Curve", a theoretical entity -

"First, the amount of tax revenue raised at the extreme tax rates of 0% and 100% is considered. It is clear that a 0% tax rate raises no revenue, but the Laffer curve hypothesis is that a 100% tax rate will also generate no revenue because at such a rate there is no longer any incentive for a rational taxpayer to earn any income, thus the revenue raised will be 100% of nothing. If both a 0% rate and 100% rate of taxation generate no revenue, it follows that there must exist at least one rate in between where tax revenue would be a maximum."

Now, is this really Math?
The affable Gardner answers this and several other knotty problems in logic in this collection of essays.

Caught at the August 2010 Boston Bookcrossing Meetup Group in Cambridge. This looks like so much fun. I like the references to papers in the "Journal of Recreational Mathematics". It just makes me smile that such a journal exists. Thanks for sharing this book!
