This document summarizes key information about four important historical scientists: - Albert Einstein proposed the theory of relativity which describes physics and motion using spacetime and is used to study reference systems. - Nicola Tesla was an important inventor who developed the Tesla coil and made contributions to alternating current, fluorescent lighting, and remote control. - Isaac Newton published his law of universal gravitation which describes gravitational interaction between bodies with mass. - Galileo Galilei invented the telescope and made important astronomical discoveries, which marked a turning point in his life and work. The document presents brief biographies and overviews of the major contributions and discoveries of each scientist.

1. HISTORIC
CHARACTERS
ENGLISH 4
CEDILLO CASTILLO HECTOR

2. INTRODUCTION.
IN THIS SLIDE SHOW TO 8 PEOPLE IT WERE IMPORTANT BECAUSE OF THEIR ACTIONS
THIS IS VERY IMPORTANT 4 CHARACTERS AS IS TESLA, NEWTON, GALILEI AND
EINSTEIN

3. ALBERT EINSTEIN
who was albert einstein?
 Was a German physicist of Jewish
origin, nationalized after U.S. and
Switzerland. It is considered as the
most important scientist of the
twentieth century.
Proposed the theory of
relativity
14 March 1879-18 April
1955

4. Theory of
relativity
ROUGHLY CONSISTS OF TWO MAJOR THEORIES (THE SPECIAL RELATIVITY AND
GENERAL RELATIVITY) MADE ​​BY ALBERT EINSTEIN IN THE EARLY TWENTIETH CENTURY
SPECIAL RELATIVITY:
DESCRIBES THE PHYSICS OF MOTION IN THE FRAMEWORK OF A FLAT
SPACETIME, CORRECTLY DESCRIBES THE MOTION OF BODIES EVEN AT HIGH SPEEDS
AND ELECTROMAGNETIC INTERACTIONS AND IS PRIMARILY USED TO STUDY INERTIAL
REFERENCE SYSTEMS.
THE THEORY GENERALIZES THE EINSTEIN RELATIVITY PRINCIPLE FOR ARBITRARY
OBSERVER.

5. NICOLA TESLA
Was an inventor, mechanical engineer and electrical
engineer of Serbian origin and most important promoter
of the birth of commercial electricity.
July 10, 1856 - January 7, 1943

6. DISCOVERYS OF TESLA
TESLA COIL:DELIVERED ENERGY OUTPUT A HIGH VOLTAGE AND HIGH
FREQUENCY.
*Alternating current
* no filament bulb or fluorescent lamp
* Remote Control

7. ISAAC NEWTON
January 4, 1643 - March
31, 1727
Was a
physicist, philosopher, theologia
n, inventor, alchemist and
English mathematician, author
of Philosophiae naturalis
principia mathematica, better
known as the Principia, which
described the law of universal
gravitation

8. law of universal
gravitation
IS A CLASSICAL PHYSICAL LAW DESCRIBING THE GRAVITATIONAL
INTERACTION BETWEEN DIFFERENT BODIES WITH MASS. THIS WAS PRESENTED
BY ISAAC NEWTON IN HIS BOOK PHILOSOPHIAE NATURALIS PRINCIPIA
MATHEMATICA, PUBLISHED IN 1687

9. GALILEO
GALILEI
(Pisa, February 15, 15644 - Florence, January 8, 1642)
Was an astronomer, philosopher, Italian mathematician
and physicist who is closely associated with the scientific
revolution. Eminent Renaissance man was interested in
almost all sciences and arts (music, literature, painting)

10. INVENTION OF THE
TELESCOPE
IT DOES NOT DEFORM OBJECTS AND INCREASES 6 TIMES, OR TWICE AS HIS
OPPONENT. IT IS ALSO THE ONLY OF THE TIME GETTING RIGHT TO OBTAIN AN
IMAGE THROUGH THE USE OF A DIVERGING LENS IN THE EYE. [CITATION
NEEDED] THIS INVENTION MARKS A TURNING POINT IN THE LIFE OF GALILEO.

11. THE END
THE REASONS ELEGI A CHARACTER IS BECAUSE THESE 3 ALBERT EINSTEIN IS A VERY
IMPORTANT PERSON IN HISTORY.
BECAUSE LIKE TESLA FOUND THE FORM OF ENERGY CURRENTLY USED AS AC POWER
GALILEO AND NEWTON AND SON OF THE BASICS OF SCIENCE AND DISCOVERY
