DESCRIPTION

Einstein failed school but was truly a genius who changed the very foundations of physics. Einstein’s four ground-breaking research papers pertaining to the Photoelectric effect, Brownian motion , special theory of relativity and E=mc2 were published in the Annalen der Physik scientific journal during 1905,the miracle year of his life.

2. CONTENTS: BIRTH EINSTEINS EARLY LIFE AND CHILDHOOD FORMATIVE YEARS GREAT WORKS 3. RELATIVITY ACHIEVEMENTS AND HONOURS DEATH 4. BIRTH Albert Einstein was born in Ulm , in Germany on 14 march 1879.His father was Hermann Einstein a salesman and engineer .His mother was Pauline Einstein. In 1880,the family moved to Munich, where his father and his uncle founded Elektrotechnische Fabrik J.Einstein & Cie ,a company that manufactured electrical equipment based on direct current. 5. WHAT LED EINSTEIN TO STUDY PHYSICS Inspiration by a magnetic compass. Interest in Euclidean geometry at a tender age. Study of the electromagnetism theory at home. 6. THE HOLY LITTLE BOOK "At the age of 12, I experienced a wonder in a booklet dealing with Euclidean plane geometry, which came into my hands at the beginning of a school year. Here were assertions, as for example the intersection of the three altitudes of a triangle in one point, which -- though by no means evident -- could nevertheless be proved with such certainty that any doubt appeared to be out of the question. This lucidity and certainty made an indescribable impression on me." 7. FORMATIVE YEARS Although he got generally good grades . In Munich, a teacher suggested Einstein to leave school,since his very presence destroyed the other students' respect for the teacher. 8. Einstein quits his school in Munich. Einstein's freedom from work and anxiety in Italy. 9. FORMATIVE YEARS II In late summer 1895,at the age of sixteen , Einstein sat the entrance examinations for the Swiss Federal Polytechnic in Zurich . He failed to reach standard in several subjects , but obtained exceptional grades in physics and mathematics . 10. In September 1896,he passed the Swiss Matura with mostly good grades(gaining max. grade 6 in physics and mathematical subjects, on a scale 1-6). 11. In 1901,Einstein research paper on capillary tubes was published In 1903, Einstein's position at the Swiss Patent Office became permanent, although he was passed over for promotion until he "fully mastered machine technology". 12. GREAT WORKS EINSTEINS ANNUS MIRABILIS(1905) Einsteins four ground-breaking research papers pertaining to the Photoelectric effect, Brownian motion , special theory of relativity and E=mc2 were published in the Annalen der Physik scientific journal. 13. RELATIVITY GRAVITATIONAL TIME DILATION. ORBITS PRECESS IN A WAY UNEXPECTED IN NEWTON'S THEORY OF GRAVITY. EXPANSION OF THE UNIVERSE. BENDING OF LIGHT IN THE PRESENCE OF GRAVITATIONAL FIELD. GENERAL THEORY OF RELATIVITY 14. SPECIAL THEORY OF RELATIVITY It was introduced in Einstein's 1905 paper, "On the Electrodynamics of Moving Bodies". Special relativity is based on two postulates 15. CONSEQUENCES 16. E=mc 2 The deep connection Einstein discovered between energy and mass is expressed in the equation E=mc2. 17. EXPERIMENTAL PROOF In Paris in 1933, Irene and Frederic Joliot-Curie took a photograph showing the conversion of energy into mass. 18. Meanwhile in Cambridge, England, the reverse process of this was seen i.e., the conversion of mass into pure energy. 19. ACHIEVEMENTS By 1908,He was appointed lecturer at the university of Bern. In 1911,he became a full professor at Karl Ferdinand university in Prague. In 1914,he was appointed director of Kaiser Wilhelm institute for physics and a professor at the Humboldt University of Berlin also he became member of Prussian academy of sciences. 20. In 1916,he became the president of German physics society. Einstein showed how to calculate Avogadros number and the size of molecules. Einsteins paper on critical opalescence. 21. Einstein challenged the wave theory of light His paper concerning the Brownian motion of particles. The development of Bose- Einstein statistics. 22. The discovery of Dark Matter. The photoelectric-effect. 23. HONOURS 24. DEATH On 17 April 1955, Albert Einstein experienced internal bleeding caused by the rupture of an abdominal aortic aneurysm, which had previously been reinforced surgically by Dr. Rudolph Nissen, in 1948.Einstein refused surgery, saying: "I want to go when I want. It is tasteless to prolong life artificially. I have done my share, it is time to go. I will do it elegantly." 25. IN THE MEMORY OF EINSTEIN 26. THANK YOU
