is he relevant in the field of maths as well?
Yes - he developed further the method of indivisibles of Cavalieri; infinite series; Telescoping series; Torricelli's trumpet (Gabriel's horn)
Evangelista Torricelli
Torricelli is also famous for the discovery of the "Torricelli's trumpet" (also - perhaps more often - known as Gabriel's Horn) whose surface area is infinite, but whose volume is finite. This was seen as an "incredible" paradox by many at the time, including Torricelli himself, and prompted a fierce controversy about the nature of infinity, also involving the philosopher Hobbes. It is supposed by some to have led to the idea of a "completed infinity". Torricelli tried several alternative proofs, attempting to prove that its surface area was also finite - all of which failed.

Torricelli was also a pioneer in the area of infinite series. In his "De dimensione parabolae" of 1644, Torricelli considered a decreasing sequence of positive terms formula_2 and showed the corresponding telescoping series formula_3 necessarily converges to formula_4, where "L" is the limit of the sequence, and in this way gives a proof of the formula for the sum of a geometric series.

Torricelli developed furt
what is the name for a weather forecaster Those using mathematical models and knowledge to prepare daily weather forecast are called "weather forecasters" or "operational meteorologists". what is weather forecasting? The application of science and technology to predict the conditions of the atmosphere for a given location and time. what are a few modern methodologies used in this regard? Barometer, Beaufort scale, Accuweather, El Niño-Southern Oscillation what is the first one? A scientific instrument that is used to measure air pressure in a certain environment. how did it get its name? The word "barometer" is derived from the meaning "weight", and meaning "measure". by whom was it developed? Evangelista Torricelli who was this person? He was an Italian physicist and mathematician, and a student of Galileo. where was he from? Rome
