Picture of the day
An
isothermal
map of the world, based on the research of
Alexander von Humboldt
, a German
naturalist
whose work laid the foundation for the sciences of
physical geography
and
meteorology
, among other things. By delineating "isothermal lines", he simultaneously suggested the idea and devised the means of comparing the
climatic
conditions of various countries.
