2. Archimede
Archimede 287 BC – c. 212 BC was a greek from
Magna Graecia, a host of Greek colonies in the
part that now is Southern Italy. He anticipated
modern calculus and analisis. He is said to have
invented machines, such as a screw pump,
compound pulleys, and defensive war machines
to protect his town, Syracuse from invasion, the
most famous being the burning mirror that
supposedly damaged the attacking Roman fleet.
3. Galileo Galilei
Astronomer, Matematician,
Physicist, 15 February 1564 – 8
January 1642. He studied the
stars and planets using a
telescope of his invention. His
discovery that the Earth turns
around the Sun made him
Famous. He was forced to deny
his discovery by the religious
authorities of the time.
4. ● Galileo's telescope
Galileo also worked in applied
science and technology,
inventing an improved military
compass and other
instruments.
5. Leonardo da Vinci
15 April 1452 – 2 May 1519. In his drawings we
can see the first helicopter, battle tank, airplane
and many other objects that were never
imagined before.

6. ALESSANDRO VOLTA
He invented the first electric battery during
his studies on electricity.
Volta studied what we now call electrical
capacitance, developing separate means to
study both electrical potential (V ) and
charge (Q ), and discovering that for a given
object, they are proportional. This may be
called Volta's Law of capacitance, and it
was for this work the unit of electrical
potential has been named the volt.
7. Bartolomeo Cristofori
● Pianoforte
The inventor of the modern piano
is most probably Bartolomeo
Cristofori (1655–1731) of Padua,
Italy, who was employed by
Ferdinando de' Medici, Grand
Prince of Tuscany, as the Keeper
of the Instruments; he was an
expert harpsichord maker, and
knew stringed keyboard
instruments like Clavicembalo very
well.
8. Luigi Galvani
Galvani discovered animal
electricity, a force that activated
the muscles of dead animals.
He thought that the activation
was generated by an electrical
fluid that is carried to the
muscles by the nerves. The
phenomenon was called
galvanism. Today, the study of
galvanic effects in biology is
called electrophysiology.
9. Antonio Meucci
1808–1889. He developed a device for voice communication
over long distance that is considered as the first telephone.
In 1849 Meucci developed a popular method of using
electric shocks to treat illness and subsequently
experimentally developed a device through which one could
hear inarticulate human voice. He called this device
"telegrafo parlante" (lit. "talking telegraph")
In a famous trial, Meucci contested the invention of the
telephone to Graham Bell.
10. Guglielmo Marconi
He is considered as the inventor of radio, and he shared the 1909 Nobel
Prize in Physics with Karl Ferdinand Braun "in recognition of their
contributions to the development of wireless telegraphy". An entrepreneur,
businessman, and founder in Britain in 1897 of The Wireless Telegraph &
Signal Company (which became the Marconi Company), Marconi
transformed radio into a commercial success of radio by innovating and
building on the work of previous experimenters and physicists.
11. Enrico Fermi
29 September 1901 – 28 November 1954, was an Italian physicist.
He is famous for his work on Chicago Pile-1 (the first nuclear
reactor), and for his contributions to the development of quantum
theory, nuclear and particle physics, and statistical mechanics. He
is one of the men that are considered as the "father of the atomic
bomb". Fermi had several patents related to the use of nuclear
power, and was awarded the 1938 Nobel Prize in Physics for his
work on induced radioactivity by neutron bombardment and the
discovery of transuranic elements. He was widely regarded as one
of the very few physicists to excel both theoretically and
experimentally.
