Weather map map using his own system of symbols, thereby creating the world's first weather map. He used his map to prove that air circulated clockwise around areas of high pressure; he coined the term 'anticyclone' to describe the phenomenon. He was also instrumental in publishing the first weather map in a newspaper, for which he modified the pantograph (an instrument for copying drawings) to inscribe the map onto printing blocks. "The Times" began printing weather maps using these methods with data from the Meteorological Office. The introduction of country-wide weather maps required the existence of national telegraph networks so that data
Methods used to study memory study memory in the macaque monkey. Elizabeth Murray and her colleagues trained monkeys to reach through the bars of their cage after a brief delay in order to displace objects under which a reward may be located. During the brief delay the monkey had to use either object recognition memory, or contextual memory to remember where the reward was located. Object recognition is tested with a matching-to-sample task where the monkey had to remember visual characteristics of the object in order to obtain the reward. Alternatively, in the non-matching-to-sample design the monkey must remember the location of the previously seen
