Down and out, английский
Nowadays meaning destitute, lacking friends, money, or prospects, this phrase comes from one of the many shouts boatswains used to roust sailors out of their hammocks. the cry “out or down!” meant that the man had better turn out, or the bosun would cut the lanyard of his hammock. once this had been done, the unfortunate man would be both down and out of bed.
Douglas scales, английский
In 1917 royal navy captain (later vice-admiral) h.p. douglas devised two nine-level scales for expressing the condition of waves and swell. the first, which he termed wind-sea, expresses the size of waves attributable to immediate and local wind effects. the second, which he named swell, refers to waves generated by distant weather conditions and characterized by regular period and flat crests. these scales were adopted by the 1929 international meteorological conference at copenhagen in an attempt to improve on the complexity of the pierson- moskowitch sea spectrum, and the rather vague wave descriptions in the beaufort scale. taken together the two douglas scales indicate the state of roughness of the sea. details are given in table 2.
