C&EN: IT'S ELEMENTAL: THE PERIODIC TABLE - INTRODUCTION National Chemistry Week, October 19-24, 2009 NCW kicks off this week with the theme "Chemistry—It's Elemental!" Visit www.acs.org/ncw for more information. The Periodic Table is nature’s rosetta stone. To the uninitiated, it’s just 100-plus numbered boxes, each containing one or two letters, arranged with an odd, skewed symmetry. To chemists, however, the periodic table reveals the organizing principles of matter, which is to say, the organizing principles of chemistry. That’s not to say, of course, that all of chemistry is obvious from the periodic table. Indeed, as John Emsley notes in his invaluable book, “Nature’s Building Blocks: An A–Z Guide to the Elements,” Mendeleyev never accepted that electrons came from atoms because he was convinced that atoms were indivisible. No matter. The periodic table is so central to chemistry that it seemed natural to devote a special issue to it and the elements that compose it as we celebrate C&EN’s 80th anniversary. Top

Obviously, there isn’t just one website capable of giving you the best deal every time. Many larger carriers make a significant amount of money off of the loyalty factor — meaning those individuals and companies who choose to fly the same airline every time for whatever reason. In most cases, the cheapest fare will be found using a combination of sites depending on your specific travel plans. This article is about Tools, Travel
