An Enigma - or is
it a Paradox?

It occurred to me the other day how in mathematics, we define

π radians = 180°

Well, according to Merriam-Webster, the definition of an irrational number (π) is "a number that can be expressed as an infinite decimal with no set of consecutive digits repeating itself indefinitely and that cannot be expressed as the quotient [or fraction] of two integers." A rational number (180) is any number that is not irrational. So have we not declared that an irrational number is equal to a rational number?

 

Acceptable Gifts for
Foreign Countries
(source: Inc Magazine Aug 2007)

India: Chocolates, dried fruits, sculptures. Present in social setting.

China: Pens, small electronic devices. Nothing white since bad connotations in superstition. Present at social event, offer 3 times.

Brazil: Personal gifts - jewelry, sports mementos. Present in social setting.

Russia: Liquor, what else? (not vodka, though). Gifts not expected in Russia.

Nigeria: Luxury items expected, but who cares? Nigeria is a hub of massive corruption and identity theft. I say give a set of strong handcuffs. Do so in a public setting.

Anyone Know What Kind of Gas Mileage a Prius Gets at 100 MPH?

Mr. Gore's son must not have gotten the memo. Looks like the family will need to purchase a few more carbon offset credits.
