1643 — Evangelista Torricelli invents the mercury barometer 1654 — Ferdinando II de' Medici, Grand Duke of Tuscany , made sealed tubes part filled with alcohol , with a bulb and stem, the first modern-style thermometer, depending on the expansion of a liquid, and independent of air pressure [ 2 ]
The experiment uses a simple barometer to measure the pressure of air, filling it with mercury up until 75% of the tube. Any air bubbles in the tube must be removed by inverting several times. After that, a clean mercury is filled once again until the tube is completely full. The barometer is then placed inverted on the dish full of mercury.
Around 1810 the wheel barometer, which could be read from a great distance, became the first practical and commercial instrument favoured by farmers and the educated classes in the UK. The face of the barometer was circular with a simple dial pointing to an easily readable scale: "Rain - Change - Dry" with the "Change" at the top centre of the ...
The Lower Paleolithic period lasted over 3 million years, during which there many human-like species evolved including toward the end of this period, Homo sapiens.The original divergence between humans and chimpanzees occurred 13 (), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being ...
The timeline of meteorology contains events of scientific and technological advancements in the area of atmospheric sciences.The most notable advancements in observational meteorology, weather forecasting, climatology, atmospheric chemistry, and atmospheric physics are listed chronologically.
Great advances in science have been termed "revolutions" since the 18th century. For example, in 1747, the French mathematician Alexis Clairaut wrote that "Newton was said in his own life to have created a revolution". [11] The word was also used in the preface to Antoine Lavoisier's 1789 work announcing the discovery of oxygen. "Few ...
Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century.
Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does not use much laboratory equipment but relies more on on-site observation and remote sensing equipment. In science, an observation, or observable, is an abstract idea that can be measured and for which data can be taken. Rain was one of ...
