OPEN-OUTCRY trading is supposed to be a
quaint, outdated practice, rapidly being replaced by sleeker, cheaper electronic
systems. Try telling that to the New York Mercantile Exchange (NYMEX), the

open-outcry pit in Dublin to handle Brent crude futures, the benchmark contract
for pricing two-thirds of the world’s oil. The NYMEX is trying to snatch liquidity from London’s International Petroleum Exchange (IPE), which trades the most Brent contracts; the New York Exchange has hitherto concentrated on West Texas Intermediate, an American benchmark grade. The new pit is a response to the IPE’s efforts to modernise. On the same day as NYMEX traders started shouting Brent prices in Dublin, the IPE did away with its morning open-outcry s A.

Clear-air turbulence often catches pilots by surprise. Invisible to radar, it is difficult to forecast and can hurl (用力抛出去) passengers about the cabin. In December 1997, one passenger died and a hundred others were injured when unexpected rough air caused a United Airlines flight over the Pacific to drop 300 metres in a few seconds.
However, passengers can avoid serious injury by fastening their seatbelts. “It is the only antidote (对策) for this sort of things,” says Rod Bogue, project manager at NASA’s Dryden Flight Research Center in Edwards, California.
The centre’s new turbulence detector is based on lidar, or laser radar, Laser pulses are sent ahead of the plane and these are then reflected back by particles in the air. The techni
