“When you are courting a nice girl, an hour seems like a second. When you sit on a red-hot cinder, a second seems like an hour. That's relativity!” –Albert Einstein

Winter in Aspen


Aspen is a mountain town, famous for great snow, located at an elevation of nearly 8,000 feet. In winter you will need hat, gloves, warm, waterproof boots or shoes, and a warm coat. Please be aware of the high-altitude effects like headache and dizziness. Drink lots of water when you first arrive, and limit physical exercise and alcohol intake. Due to the intensity of the reflection from the snow and the altitude, sunscreen and sunglasses are essential.


Aspen has four ski areas reaching an altitude of about 12,000 feet. The Physics Center sells discounted lift tickets. You may purchase these daily at the Aspen Center for Physics and will be given a Mountain Advantage Card (MAC) for a discount of up to 35% on ski and snowboard rentals. You will need gloves, a helmet or hat, sunglasses and/or goggles, wool socks, waterproof pants, and a parka. Limited used ski items are for sale at the Aspen Thrift Shop, and at full retail all over Aspen and Snowmass. The business, Suit Yourself rents pants, jackets, hats, gloves and goggles for kids and adults.

Ski School starts at 10 am which interferes with our morning conference sessions but the Aspen Skiing Company has arranged a special physicists' afternoon ski lesson provided we have at least three people in the group who ski at the same level. This lesson is offered at a significantly reduced price from the usual private lessons. All-day ski school for children is always available and since children come from all over the world, the ski instructors communicate well with any age, any native language.

Transportation in Aspen

The Aspen Meadows offers shuttle service to the Physics Center and into town. RFTA offers free city buses to all ski areas and to the Aspen Recreation Center. There is also a free shuttle that goes from 5th and Gillespie Streets (one block from the Physics Center) to town at 15 minutes before and after the hour.
