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 G.E. Müller who continued the tradition of lists of items to conduct memory experiments on human subjects and using behavioral data to develop models of memory. The two most common types of memory studied using these methods are recognition and recall. Recognition memory is the ability to judge whether or not the cued item was previously presented on the list usually with a yes or no response. This memory is akin to the type of memory used for police line-ups. The particular task described used to be called "item recognition". Scientists study the rates of hits (correct "yes" responses) related
