2. Archimedes Archimedes of Syracuse
(Greek: Ἀρχιμήδης; c. 287 BC - c. 212 BC) was a mathematician,  a physicist,  an engineer, an inventor, and an astronomer. Archimedes is generally considered to be the greatest mathematician of the past and one of the greatest of all time.
Archimedes died c. 212 BC during the Second Punic War, when Roman forces under General Marcus Claudius Marcellus captured the city of Syracuse after a two-year-long siege.

4. The II principle of hydrostatic
A body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.

5. Archimedes’ screw
Archimedes' machine was a device with a revolving screw-shaped blade inside a cylinder. It was turned by hand, and could also be used to transfer water from a low-lying body of water into irrigation canals. The Archimedes screw is still in use today for pumping liquids and granulated solids such as coal and grain.

6. Leonardo da Vinci
A genius man and universal talent of the italian Renaissance, Leonardo Da Vinci embodied the universal spirit of his age, leading it in various fields.
He was a painter, a carver, an architect, an engineer, a mathematician, an anatomist, a musician and a great inventor.

10. Galileo Galilei
Galileo Galilei was an Italian physicist,a mathematician,an astronomer and a philosopher who played an important role in the Scientific Revolution.
His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism.

11. Telescope
Galileo in 1609 made a telescope with about 3x magnification. He later made improved versions with up to about 30x magnification.
With a Galilean telescope the observer could see magnified, upright images on the earth – it was what is commonly known as a terrestrial telescope, or spyglass.
He could also use it to observe the sky.

12. Thermoscope
At the start of the seventeenth century there was no way to quantify heat. In Aristotelian matter theory, heat and cold were fundamental qualities. The first solution was a thermoscope. Galileo had then made use of this effect in order to construct an instrument for examining the degrees of heat and cold.

13. Alessandro Volta
Alessandro Volta was born in Como, Italy in In 1774, he was appointed as professor of physics at the Royal School in Como. Here he designed his first invention: the electrophorus, a device that produced static electricity. For years at Como, he studied and experimented with atmospheric electricity by igniting static sparks. In 1779, Alessandro Volta was appointed as a professor of physics at the University of Pavia

14. Voltaic Pile
Constructed of alternating discs of zinc and copper, with pieces of cardboard soaked in brine between the metals, the voltaic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. His voltaic pile was the first battery that produced a reliable, steady current of electricity.

15. Antonio Meucci
Antonio Meucci invented the telephone. He was born in Florence in He was admitted to Florence Academy of Fine  where he studied chemical and mechanical engineering.

16. Telephone
In 1834 Meucci constructed a type of acoustic telephone  to communicate. This telephone was constructed on the principles of pipe-telephones used on ships .
