During the first week of September, the 1987 World Track and Field Championships will be held in Rome. The casual viewer of "NBC Sportsworld" has undoubtedly seen the events before--the pole vault, steeplechase, sprints and hurdles. But most people haven't developed an appreciation for what the athletes do to accomplish such feats...
...order to get an appreciation of the track athlete, one has to go to a meet and experience what happens on the infield. Fortunately, I attended the Greater Boston Championships in Dedham a month ago and investigated...
...against my ear. I noticed that the weight was shifted mostly to the rear which made the javelin appear unbalanced. Possibly, this weight shift occurred in response to a 104.41-meter throw by a Polish athlete that sailed off the throwing surface and nearly hit a runner on the track...
Throughout the day, various obstacles were placed on the track. One of the more fascinating races that involved obstacles was the 110 high hurdles. When I compared the height of the hurdles to the height of most of the athletes, I realized that only Manute Bol could possibly run the race without hurting himself. Maybe Spud Webb could run under the hurdles and achieve the same goal...
...little interest to maglev engineers, who abandoned superconducting magnets in 1979. They opted to use conventional electromagnets instead. The German system is based on magnetic attraction, not repulsion. The magnets are on assemblies attached to the cars' undercarriages that curve around and under the crossbar of a T-shaped track. When the magnets are energized, they pull themselves up toward the crossbar's metallic underside and the car is lifted into the air; magnets in the track provide propulsion. Which technique is better? Both have advantages. The German maglev is simpler and less expensive to operate...
