Albert Einstein (1879 -1955)

**
Einstein was
born on March 14, 1879 in the German city of ****Ulm****, but spent all
his childhood and adolescence in ****Munich**** wher****
He started to talk very
late and this fact alarmed the whole family.** **
He was a poor student, considered
impaired by teachers, and was finally expelled from Luitpold school in ****Munich****, at the age of
15.** **He gave up his German
citizenship and went to live with his family in ****Milan****, where he
studied Mathematics, Physics and Natural Sciences.** **Even without finishing
high school, he took the entry exam at the ****Zurich**** Polytechnic, but
he didn't pass it. However, he already dominated, with only 16 years, the
concepts of integration and differential calculus, the analytic geometry and
the endless series.** **The following
year, he started attending high school in Aarau, where he spent most of the
time in the Physics' laboratory, finally making it to ****Zurich**** Polytechnic in
1896, where he graduated as a physics and mathematics secondary school teacher.**

** ****Based on
discoveries of Max Planck on the emission of electromagnetic energy,
Einstein interpreted the photoelectric effect, for which he received the
Nobel Prize of Physics 1921. In 1905, he had published the text which
founded the theory of Special Relativity and would be worked in
mathematical terms by Minkowski
in 1907. In this year Einstein drew up the principle of equivalence between
mass and energy, reaching the equation E = mc^{2.} Based
on the calculations of Minkowski and with the collaboration of Marcel Grossam
in 1912, the mathematical foundations of the theory of General Relativity would
be published in 1915. This same year, Einstein left **

**Berlin**

**where he had occupied the post of professor at the Kaiser Wilhelm Gesellshaft since 1914, and in the**

**United States**

**, at**

**Princeton**

**University**

**.**

**Einstein died on**

**April 18, 1955**

**in**

**Princeton**

**without finding an universal unifying theory**
