2. Albert Einstein
Albert Einstein (/ˈaɪnstaɪn/
German: [ˈalbɛɐ̯ t ˈaɪnʃtaɪn] ( listen);
14 March 1879 – 18 April 1955)
was a German-born theoretical
physicist. He developed the general
theory of relativity, one of the two
pillars of modern physics
(alongside quantum mechanics).
Einstein is best known in popular
culture for his mass–energy
equivalence formula E = mc2
(which has been dubbed "the
world's most famous equation").
Einstein's intellectual
achievements and originality have
made the word "Einstein

3. Isaac Newton
Sir Isaac Newton (25 December
1642 – 20 March 1726) was an
English physicist and
mathematician.
Newton's Principia formulated the
laws of motion and universal
gravitation, which dominated
scientists' view of the physical
universe for the next three centuries.
Newton built the first practical
reflecting telescope and
developed a theory of colour
based on the observation that a
prism decomposes white light into
the many colours of the visible
spectrum.

4. Marie Curie
Marie Skłodowska Curie (7
November 1867 – 4 July 1934), born
Maria Salomea Skłodowska, was a
Polish and naturalized-French
physicist and chemist who conducted
pioneering research on radioactivity.
She was the first woman to win a
Nobel Prize, the first person and only
woman to win twice, the only person
to win twice in multiple sciences.
Her achievements included the
development of the theory of
radioactivity (a term that she coined),
techniques for isolating radioactive
isotopes, and the discovery of two
elements, polonium and radium

5. Stephen Hawking
Stephen William Hawking (8
January 1942) is an English
theoretical physicist, cosmologist,
author and Director of Research
at the Centre for Theoretical
Cosmology within the University
of Cambridge.
His scientific works include a
collaboration with Roger Penrose
on gravitational singularity
theorems in the framework of
general relativity, and the
theoretical prediction that black
holes emit radiation, often called
Hawking radiation.

6. Archimedes
InArchimedes of Syracuse (c.
287 BC –c. 212 BC) was an
Ancient Greek mathematician,
physicist, engineer, inventor, and
astronomer.
 the 3rd Century BC,
Archimedes:
Invented the sciences of
mechanics and hydrostatics.
Discovered the laws of
levers and pulleys, which
allow us to move heavy
objects using small forces.
Invented one of the most
fundamental concepts of
physics – the center of gravity.

7. Nikola Tesla
 Nikola Tesla (10 July 1856
– 7 January 1943) was a
Serbian American physicist,
inventor, electrical engineer,
mechanical engineer and
futurist best known for his
contributions to the design of
the modern alternating current
(AC) electricity supply system.
 His work fell into relative
obscurity after his death, but in
1960 the General Conference
on Weights and Measures
named the SI unit of magnetic
flux density the tesla in his
honor.

8. Thomas Edison
 Thomas Alva Edison (February 11,
1847 – October 18, 1931) was an
American inventor and businessman.
He developed many devices that
greatly influenced life around the world,
including the phonograph, the motion
picture camera, and the long-lasting,
practical electric light bulb.
 He also
invented the
electric chair, in
order to prove
that alternative
current is also
harmul, not only
benefic.

9. Alfred Nobel
 Alfred Bernhard Nobel (21
October 1833
– 10 December 1896) was a
Swedish chemist, engineer,
innovator, and armaments
manufacturer.
 He was the inventor of dynamite.
Nobel also owned Bofors,. Nobel
held 355 different patents, dynamite
being the most famous. His fortune
was used posthumously to institute
the Nobel Prizes. The synthetic
element nobelium was named after
him.
 His name also survives in
modern-day companies such as
Dynamit Nobel and AkzoNobel,
which are descendants of mergers
with companies Nobel himself
established.

10. Alessandro Volta
 Alessandro Giuseppe
Antonio Anastasio Volta (18
February 1745 – 5 March 1827)
was an Italian physicist, chemist,
and a pioneer of electricity and
power, who is credited as the
inventor of the electrical battery
and the discoverer of methane.
 With this invention Volta proved
that electricity could be generated
chemically and debased the
prevalent theory that electricity
was generated solely by living
beings. Volta's invention sparked a
great amount of scientific
excitement and led others to
conduct.

11. Benjamin Franklin
 Benjamin Franklin (1706
January 6, 1705 – April 17,
1790) was one of the Founding
Fathers of the United States.
 Franklin's discoveries resulted
from his investigations of
electricity. Franklin proposed
that "vitreous" and "resinous"
electricity were not different
types of "electrical fluid
 He was the first to label them
as positive and negative
respectively.
 He was the first to discover
the principle of conservation of
charge.

12. Michael Faraday
 Michael Faraday (22 September
1791 – 25 August 1867) was an
English scientist who contributed to
the fields of electromagnetism and
electrochemistry.
 His main discoveries include
those of electromagnetic induction,
diamagnetism and electrolysis.
 It was by his research on the
magnetic field around a conductor
carrying a direct current that
Faraday established the basis for
the concept of the electromagnetic
field in physics.
