Albert Einstein's most
influential scientist on earth. He is a scientist who is considered the
greatest scientist of the 20th century thanks to his thoughts.
His greatest contribution
to science is his well-known theory of relativity and his famous formula is E =
mc² which from the formula makes America able to create atomic bombs and defeat
japan. Albert Einstein was born on 14 March 1879 in Ulm, the Kingdom of
Wurttemberg, the German Empire.
Albert Einstein
Albert Einstein was the
first child of the couple Hermann Einstein and Pauline, Einstein looked
different from other children around him because of the autism he had suffered.
With slow progress, he is
less able to get along with his peers. When school Albert Einstein known as a
figure who is considered stupid, like to oppose the order and look shy.
At the age of five a
compass sac was shown to him by his father, where Einstein began to ask why the
needle always pointed north and south? Until he realizes that in this
"empty" space it acts against a compass needle.
At the age of 12 Albert
Einstein began to deepen his interest in mathematics. In 1896 Albert Einstein
earned a diploma, then he has a determination to continue studying in college.
But at that time Einstein
did not pass the entrance exam to college, the following year he took the exam
again and finally get admitted to the Eidgenossiche Techniche Hochschule (Swiss
Federal Institute of Technology) in Zurich.
Entering college the
nature of laziness still has not changed, he often did not follow the lecture
but he always persevered alone to learn the theory of physics he loved.
In 1985 until 1905 Albert
Einstetin always conducted research on Special Theory of Relativity. Thanks to
his discovery in 1905 he earned a doctorate with a thesis entitled On a New
Determination of Molecular Dimensions at the University of Zurich, Switzerland.

In 1912 Albert Einsten
taught at the University of Germany in Prague until then in 1913 he was
appointed Director of the Institute of Physics of the Emperor Wilhlem in
Berlin, Germany.
In his journey he
continued to develop his research to be able to find the Theory of General
Relativity in 1915.
What is the Theory of Relativity?
The theory of relativity
proposed by Albert Einstein is a term for a collection of two theories of
physics namely "general relativity" and "special
relativity".
This theory was invented
by Einstein to explain that electromagnetic waves do not fit the Newtonian
movement theory.
At a constant speed, the
electromagnetic waves can move without the movement of the observer.
The point is that although
the contents of the laws of physics look the same, it is actually that two
observers moving relative to each will get different time and space interval
for the same event.
Special Relativity
Special relativity is a
theory of space-time structure, the theory was introduced by Albert Einstein in
1905.
This theory explains that
if two observers are in an inert frame of motion and are moving at a relatively
similar speed with other observers, then both observers can not experiment
whether they are in a position of motion or silence.
One thing for example is
when a person is on a speeding submarine, then one can not tell whether the
submarine is still or moving.
... Learn from the past, live for the future. The important thing is not to stop asking . - Albert Einstein
General Relativity
General relativity is a
theory of geometry about gravity introduced by Einstein. This theory explains
the latest gravity in modern physics. In this theory it is explained that
seeing gravity is not as a force, but rather seen as a manifestation of the
curvature of a space and time.
Many seem to differ on the
predictions of general relativity with the predictions of classical physics,
and predominant predictions about the geometry of space, the motion of free
falling objects, the passage of time and the propagation of light.
All predictions of general
theory of realism have been confirmed in experiments and various observations
of physics. Although this theory is not the only theory of relativistic
gravity, it is the simplest and most consistent theory with experimental data.
Formula-emc2His discovery
of the theory of relativity is the theory that is considered the greatest in
all time. The formula E = MC² is the formula used to study the universe. Where
E = energy, m = mass, and c = the speed of light.
Nevertheless, there are
still many questions that may not be answered until now. There is also a
fundamental question in which general relativity can be combined with laws in
quantum physics in order to create a complete theory of quantum gravity and
self-consistency.
The following is a brief
review of the essence of the Discovery History Theory of Relativity By Albert
Einstein may be useful and add insight for us all.
