In his observations of other types of birds and their skill to fly, he spotted that every one birds, whether or not they have been as small as finches or as huge as eagles and vultures, have been capable of get airborne and start and upward thrust on air currents both good. those observations led Leonardo to think that the wind legislation just like these of water, and if he may know how wind and air swirled and pooled within the sky, he may perhaps determine easy methods to fly. Leonardo drew many designs for machines that may degree the “quality and thickness of the air,” together with units that measured air humidity and the move of air over various surfaces. this sort of units was once a mechanical anemometer, that's a computing device for measuring windspeed. in a single of his notebooks Leonardo drew an easy lever anemometer, which used to be a body maintaining a free-swinging disk. the belief in the back of the anemometer was once uncomplicated: whilst the wind blew, it should push the disk up the size marked at the aspect of the body and convey, very in short, what the strength of the wind used to be at any given second. the assumption of measuring windspeed didn’t commence with Leonardo. in reality, the 1st mechanical anemometer was once created by way of one other very well-known Italian, Leon Battista Alberti. In 1450, many years prior to Leonardo was once born, Battista designed the disk anemometer that Leonardo drew a long time later. yet Leonardo’s contribution to the examine of windspeed took Alberti’s suggestion a section additional.
