[00:00]wedge

[00:02]Robert Fulton once wrote, "The mechanic should sit

[00:06]down among levers, screws, wedges, wheels, etc., like

[00:11]a poet among the letters of the alphabet, considering

[00:14]them as an exhibition of his thoughts, in which a new

[00:17]arrangement transmits a new idea."

[00:23]sledge

[00:25]The snowy slopes beckon and the urge to hurtle down

[00:29]them takes over but there is no sledge available. So you

[00:34]grab a tea tray, an old bag, a coat - or, if you are a police

[00:38]officer, a riot shield.

[00:44]Jets safety Jim Leonhard has a bright pink shiner under

[00:49]his left eye to match the bright pink smudge on the right

[00:53]thumb that he broke earlier this season.

[00:56]ridge

[00:57]The underwater landscape of 6,000m deep trenches,

[01:02]oceanic ridges and sea mounts, is also a refuge and

[01:06]breeding ground for large and important populations of

[01:10]sharks, dolphins, marine turtles, rare crabs, birds and

[01:15]other vulnerable species.

[01:19]lodge

[01:21]In Britain its chronology still overhangs the national

[01:24]curriculum. Its poems and songs-such poems, such

[01:28]songs, as if war's horror and nonsense had never been

[01:33]articulated before - still lodge in people's heads.

[01:40]helmet

[01:42]"We're really sorry he has become paralyzed, but

[01:45]helmets aren't designed to prevent those kinds of

[01:48]injuries," says Nimmons.

[01:51]comet

[01:53]A swarm of comets that smacked North America 12,900

[01:57]years ago wiped out the wooly mammoth and early Native

[02:01]American cultures, according to a soil study released

[02:05]Thursday.

[02:07]hazard

[02:10]The misuse of UK passports not only presented

[02:13]a hazard to British nationals in the region but also

[02:17]represented a "profound disregard" for the sovereignty of

[02:20]the United Kingdom, the foreign secretary said.
