Albert Einstein was born in Germany in 1879. He published his special theory of relativity in 1905 which established that the laws of physics are the same in all inertial frames of reference and that the speed of light in a vacuum is constant. In 1915, Einstein published his general theory of relativity which proposed that gravity is related to the curvature of spacetime caused by the uneven distribution of mass/energy. The theory revolutionized physics and transformed our understanding of space and time.

2. Albert Einstein was born 14th may 1897 in the Bavarian city of
ULM. He was the first of 2 siblings, and he was Jewish.
Albert was a very quiet and shy boy, but he was a bit slower
than the rest of the people, which is better because he
started thinking and asking questions to himself when he
was an adult.
They moved to Munich and the to Zurich, where Albert started
his superior studies. in 1901 he got his first job as civil
servant in the research office of Berne.
In1903 he married Mileva Maric and they had 2 sons, but the
marriage lasted few, they got divorced in 1919, and he
married again his cousin Elsa.
He was very good at physics and in 1905 he published his first
articles about special relativity, Brownian movement …
After this, Albert became very popular, and in 1909 he
obtained the job of professor in the university of Zurich. Ç
1916 he published the General theory of relativity, and in 1921
he received the Nobel prize in Physics.
He had to abandoned Germany because of Hitler's
dictatorship, and he moved to USA where he would be a
catedratic in the university of Princeton.
1939 he asked roosevelt for the investment in the Atomic
bomb project.
And finally in 1955 he died in Princeton(USA)


Albert Einstein stated the Special Theory of Relativity in
1905. This theory included new concepts of space and
time:
Physics laws are valid for non-accelerated objects.
Light speed in a vacuum is independent of the observers
´motion

He spent some years trying to include acceleration in his
theory. In 1915 he published his General Theory of Relativity.
Gravity is the force that attracts two objects.
The fastest velocity is the light velocity.
He discovered that the light in a vacuum has the same speed
no matter the speed of the observer. As a result he realized
that space and time were interwoven. (Events that occur at a
specific time for an observer, could occur at a different time for
another).
Massive objects caused a distortion in space-time.

6.  The
theory of relativity has strongly influenced
developments
in
advanced
physics, geometry, astronomy and cosmology
(origin and structure of the universe).
 Equations used and proved in the theory have
helped to develop different theories between
them some related to geometry and most
importantly to the gravitational force.
 It has helped to develop the principle of
equivalence.
 The theory is used to study the overall structure
of the universe and therefore to expand our
knowledge of cosmology.

7.  Using
the theory several scientists have
discovered natural phenomena such as black
holes and gravitational lenses.
 In modern physics it has shown scientists
that it is possible to unleash the energy
contained in the nucleus of an atom.
 Has affected the application of nuclear
production, and therefore has helped to
alleviate a portion of our reliance on non
renewable resources for our energy needs.
 as well as the synchronization of the global
positioning system (GPS).
