Early Life and Education

Albert Einstein was born into a middle-class Jewish family in Ulm, Germany. He showed an early interest in mathematics and science but struggled with the rigid school system of his time. At age 16, he left school without a diploma and later enrolled in the Swiss Federal Polytechnic in Zurich. He graduated in 1900 with a degree in physics.

Professional Life

Einstein’s career can be divided into several key phases:

1. The Miracle Year (1905):
   Einstein published four groundbreaking papers, including his special theory of relativity and the famous equation $E=mc^2$, which established him as a leading scientist.

2. Academic Positions:
   He worked at the Swiss Patent Office before holding professorships in Zurich, Prague, and Berlin.

3. Nobel Prize (1921):
   Einstein was awarded the Nobel Prize in Physics for his explanation of the photoelectric effect, which laid the foundation for quantum theory.

4. Relativity and Global Fame:
   His general theory of relativity (1915) predicted phenomena like the bending of light by gravity, which was confirmed in 1919, catapulting him to international fame.

5. Later Years in the U.S.:
   Fleeing Nazi persecution, Einstein moved to the United States in 1933 and became a professor at Princeton University. He remained there until his death.

6. Activism and Humanitarian Work:
   Einstein was a vocal advocate for civil rights, Zionism, and nuclear disarmament, and he declined the offer to become Israel’s first president in 1952.

Lesser-Known and Interesting Facts About Albert Einstein

1. He Had a Speech Delay as a Child:
   Einstein didn't start speaking fluently until he was around four years old, which concerned his parents. This has led to a term called "Einstein Syndrome," referring to late speech development in highly intelligent individuals.

2. Einstein’s Brain Was Preserved After His Death:
   Pathologist Thomas Stoltz Harvey removed Einstein’s brain during his autopsy without family consent, intending to study it for insights into his genius. The brain was preserved and studied for decades, revealing unusual features in its structure.

3. He Failed a University Entrance Exam:
   At 16, Einstein failed the entrance exam for the Swiss Federal Polytechnic in Zurich. While he excelled in math and physics, he performed poorly in other subjects, including languages.

4. He Had a Secret Daughter:
   Einstein and Mileva Marić had a daughter, Lieserl, before their marriage. Little is known about her fate, as some records suggest she may have been given up for adoption or passed away at a young age.

5. He Had a Poor Memory for Everyday Things:
   Despite his intellectual brilliance, Einstein often forgot mundane details like appointments, names, and even his own phone number.

6. Einstein Loved Sailing but Couldn’t Swim:
   He was passionate about sailing and owned a small boat. However, he never learned how to swim and admitted to being clumsy at handling the vessel.

7. He Was a Target of Nazi Propaganda:
   During Hitler's rise to power, Einstein, a Jewish scientist, became a target of Nazi propaganda, which labeled his theories as "Jewish physics." He fled Germany in 1933 and never returned.

8. He Never Wore Socks:
   Einstein found socks unnecessary and avoided wearing them altogether, claiming they would often develop holes, so he preferred going without.

9. He Played a Role in the Atomic Bomb’s Development (Indirectly):
   Though a pacifist, Einstein signed a letter to President Franklin D. Roosevelt, co-written by physicist Leo Szilard, urging the U.S. to develop nuclear weapons in response to Nazi Germany’s potential threat.

10. He Had a Sense of Humor:
