PHYSICS

 Already in ancient Greece, Aristotle, Archimedes and Heron of Alexandria had carried out studies on floating objects, weight, as well as the movement of the wheel, the pulley, among others. These advances allowed Arab intellectuals such as Al-Khazini, Al-Birûni, among others, to experiment with the theories of their predecessors, reaching the following discoveries: • The effect of the voice is produced due to the movement of the bodies that generate it. , and are transmitted in the air in the form of spherical waves, this was called acoustics. • The density and gravity of the objects (eighteen precious stones), and its coincidence with the volume of water that pushes it, which gives rise to the dynamics. • The balance was invented to weigh objects in air and water. • The barometer (pressure balance) was another invention that allowed Torrecelli, Pascal and Boyle to perfect and study the pressure of gases.
