Faux says that the obvious solution is for stopwatches to have large data tables for transforming the numbers of oscilla- tions into the time in seconds,rather than using an algorithm. The researchers now hope to investigate whether the errors are found at large sporting events. New Scientist asked the International Olympic Committee if timing at the Olympic Games could be affected by this phenome- non.The IOC passed the request for comment to Omega,the of ficial timekeeper of the Games,which didn't respond.

Digital stopwatches can make rounding(四舍五入的)errors of up to 0.11 seconds,which could be enough to change the win- ner of close races.Although the devices record time extremely accurately,they often make errors when changing that raw data to human-readable numbers. Most digital stopwatches measure time by counting the pre dictable oscillations (of a quartz crystal.The crystal will pulse many thousands of times a second and the final count is transformed into seconds in a format known as a floating-point representation that is commonly used by digital devices. This floating-point number is extremely accurate,but must be transformed again for display on the limited screen of a stop-

B The e-mail request came in to Ekiben restaurant in Balti- more,Maryland one afternoon:tempura broccoli(面拖花椰菜).
