Birth and Early YearsAlbert Einstein was born on March 14, 1879, in Ulm, Germany. He was the first child of two non-observant Jewish parents, Hermann Einstein, a Jewish merchant, and Pauline Einstein, a non-Jewish Catholic. Albert's early years were spent in Munich, where he attended elementary school. However, due to anti-Semitic policies implemented by the Bavarian government, his family moved to Switzerland in 1894.In Switzerland, Einstein completed his high school education at the Cantonal School in Aarau. He excelled in mathematics and physics, two subjects that would later become the focus of his studies. After graduating in 1896, he enrolled in the Federal Polytechnic School in Zurich to pursue a degree in electrical engineering. However, he became dissatisfied with the structured and traditional teaching methods at the school and decided to pursue a degree in physics independently.Studies and Work in Switzerland and GermanyIn 1900, Einstein graduated from the University of Zurich with a teaching diploma in mathematics and physics. He began teaching mathematics and physics at a series of Swiss schools, including the Cantonal School in Winterthur and the Federal Polytechnic School in Zurich. During this period, he published several articles on electricity, magnetism, and thermodynamics, subjects that would become fundamental to his future work.In 1902, Einstein was appointed as a technical expert at the Swiss patent office in Bern. This position allowed him to focus on his research while also receiving a stable income. Over the next few years, he published several more articles on statistical mechanics and thermodynamics, introducing new concepts such as the concept of entropy for classical statistical systems.The Annus Mirabilis and International RecognitionIn 1905, Einstein published a series of four groundbreaking papers that would change the direction of physics and science forever. These papers were on special relativity, Brownian motion, the photoelectric effect, and energy quanta. The papers on special relativity and the photoelectric effect particularly revolutionized the field of physics. The former introduced the concept of spacetime and showed that mass and energy are equivalent (E=mc²), while the latter showed that light can be described as a particle with an associated energy quantum.These papers brought Einstein international recognition and he was soon appointed as a professor at the University of Zurich. In 1911, he was appointed as a professor at the German University in Prague, where he remained until 1914. While in Prague, Einstein formulated his general theory of relativity, which explained gravitation as a consequence of the curvature of spacetime.General Theory of Relativity and Later YearsIn 1915, Einstein published his general theory of relativity, which explained gravitation as a consequence of the curvature of spacetime. The theory revolutionized our understanding of gravity and marked a turning point in Einstein's career. The following year, he was awarded the Nobel Prize in Physics for his work on the photoelectric effect.After the publication of his general theory of relativity, Einstein continued to work on a number of projects that would further develop his ideas on physics. He was particularly interested in unifying his theory of relativity with quantum mechanics to explain the behavior of subatomic particles. His work on quantum gravity and unified field theories remained elusive despite his best efforts. However, his contributions to physics remain fundamental and include laying the groundwork for many modern technologies such as GPS systems and nuclear energy production.Einstein's later years were spent dividing his time between the United States and Switzerland. He became an American citizen in 1940 and remained active in the world of science until his death on April 18, 1955. He is remembered as one of the most important thinkers and scientists of our time, whose contributions to physics and science continue to shape our understanding of the universe even today.
