This instrument sparked a bitter controversy with Jean-André Deluc, who had invented a whalebone hygrometer. [12] In 1767, Saussure constructed the first known Western solar oven, trying several designs before determining that a well-insulated box with three layers of glass to trap outgoing thermal radiation produced the most heat.

Abu al-Qasim al-Zahrawi (936–1013 AD), better known in the west as Albucasis, is regarded as the father of modern surgery and is the most quoted surgeon of all times. Albucasis invented over 200 tools for use in surgery - many still in use today. Water and weight driven mechanical clocks, by Spanish Muslim engineers sometime between 900 ...
The hygrometer, made of cardboard, shows a figure consisting of a friar of the Capuchin Order [3] with an open book in his right hand and the left arm and the hood of the habit mobile thanks to balanced axes; In this arm he carries a bar thanks to which he indicates the weather approximately 24 hours in advance on various signs arranged from top to bottom on a column while he moves his hood to ...

[30] Juan de Herrera (1530-1597), architect, mathematician and geometer, designed the construction plans of El Escorial and the Cathedral of Valladolid among others and created a compass to measure length and width and a machine to cut iron.

A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.
In 1441, King Sejong's son, Prince Munjong, invented the first standardized rain gauge. These were sent throughout the Joseon dynasty of South Korea as an official tool to assess land taxes based upon a farmer's potential harvest. In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and is known as the first anemometer. [1]
Since the second decade of the 21st century, the departure of many private companies abroad, forced by the 2008–2013 crisis, has resulted in the need to compete and survive in the global market, especially in emerging markets, generating greater scientific application and technology, and consequently greater private investment in research.
1836 – An American scientist, Dr. David Alter, invented the first known American electric telegraph in Elderton, Pennsylvania, one year before the much more popular Morse telegraph was invented. 1837 – Samuel Morse independently developed an electrical telegraph , an alternative design that was capable of transmitting over long distances ...
