In 1611, Johannes Kepler wrote the first scientific treatise on snow crystals: "Strena Seu de Nive Sexangula (A New Year's Gift of Hexagonal Snow)". In 1643, Evangelista Torricelli invented the mercury barometer. In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge. In 1714, Gabriel Fahrenheit created a reliable scale for measuring temperature with a mercury-type thermometer. In 1742, Anders Celsius, a Swedish astronomer, proposed the "centigrade" temperature scale, the predecessor of the current Celsius scale. In 1783, the first hair hygrometer was demonstrated by
Celsius 41.11 "Fahrenheit 9/11", as "well crafted" believing that, while Moore had angered the targets of his film he "went the extra mile, creatively, to do so". In contrast Kennicott described "Celsius 41.11" as "dull, lazy and inconsistent". "Celsius 41.11" was criticised for sharing some of what reviewers perceived to be the flaws of "Fahrenheit 9/11". For example, Desson Thomson of the "Washington Post" (although generally positive about "Celsius 41.11") said that in the case of both films "the spleen factor could poison small children". Writing in the "Milwaukee Journal Sentinel" Duane Dudek said, "as with "Fahrenheit 9/11", it's impossible to separate
