Torricelli tried several alternative proofs, attempting to prove that its surface area was also finite – all of which failed. The photo is taken from upward angle while performing Torricelli’s experiment.

The book was published in 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. Seeing his talents, his parents sent him to be educated in Faenza, under the care of his uncle, Giacomo Jacoba Camaldolese monkwho first ensured that his nephew was given a sound basic education.
