In recognition of this, the JOM feature on page 17 looks at the role that advanced materials technology will play in several Olympic events. Skis are among the most complex pieces of winter sports equipment as demonstrated by Tim Kelley, U.S. Ski Team, as he trains slalom in Saas Fee, Switzerland.

And, in many cases, I want to see the exhibition most of all. A confer- ence exhibition is nothing like TV ads . it’s like shopping at a specialty mall that exists at one place on earth for three days only and that is built just for you. For PUBLISHER those of you reading this editorial while ensconced at the TMS 2010 Annual Meeting James J. Robinson in Seattle, that mall is here, and those three days are now. FEBRUARY ADVISORS Exhibitions are a trove of potential delights: Will someone who I want to visit Aluminum be hosting a booth? Will I see some neat stuff demonstrated? Will there be irresist- Aluminum Committee ible new widgets? Will there be food? Will there be gotta-have souvenirs? Most Pierre Homsi, Consultant, importantly, will I fi nd something that is going to make my workplace more effi cient, retired from Rio Tinto Alcan competitive, and (dare I hope?) fun?

In recent years, however, the Peter K.

EDITORIAL STAFF Maureen Byko, Editor TMS’s director of partner relations, Trudi Dunlap, leads our effort to make sure Cheryl M.
