Skis, both for people and for aircraft, used to be made of waxed wood. Down to about -10° C, the friction of waxed wood on snow is very low - [jl is about 0.02 - and if this were not so, planes equipped with skis could not take off from packed-snow runways, and the winter tourist traffic to Switzerland would drop sharply. Below -10° C, bad things start to happen (Fig. 26.6) (jl rises sharply to about 0.4. Polar explorers have observed this repeatedly. Wright, a member of the 1911-13 Scott expedition, writes Below 0°F (-18°C) the friction (on the sledge runners) seemed to increase progressively as the temperature fell it caused the expedition considerable hardship. What determines the friction of skis on snow ... 

Herman F. Mark and his wife, Mimi, true to their Viennese heritage, love winter, snow, and especially the sports of winter. From boyhood until his seventies when his doctors made him stop, he has skied, hiked, and climbed with a ferver matched only by his activities in the physical sciences. Just as an example, his love of these activities influenced his decision to enlist in the Kaiserschutzen regiment, an elite Alpine infantry unit, in 1913. 

In 2006 around 35% of aU ski slopes in the Alps - or roughly 35,000 hectares -were covered with artificial snow. But a comparison with other European countries shows major differences (Fig. 6). If one assumes that 2,000 m of water per hectare need to be used for artificial snowmaking [8], this results in an annual water requirement of 70 million cubic meters for the alpine region as a whole. The estimated volume for Switzerland is around 8.4 million cubic meters.

This horticultural extravaganza immediately followed an ecstatic run downhill on skis. I explained to my old friend and crony, Peter Thompson, that my first run was so painfully awkward that I was hesitant to try again. But, as is often the case, I found my ski legs on the second run and I swerved, cut, jumped, and carved my way rapidly downhill through the soft spring snow. Peter said that he had not tried to ski in years but remembered our early adventures on the slopes together and asked me to take him with me again. I said, Sure. ... 

Water in the swimming pool and snow on the ski slopes reflect sun s rays. At the same time, the swimmers and skiers absorb the sun s rays that strike them. Therefore, they get a double dose of energy from the sun. 

In world-class competitions such as the Olympics, the difference between winning a gold medal and watching on the sidelines often depends on a hundredth of a second. For skiers, it boils down to what type of ski wax they use to reduce the friction of skis on snow. 

Snomax A strain of bacteria related to Frostban that promotes freezing. Snomax is being used in ski resorts on snow-making machines.
