When was einstein born

On March 14, , Alexander Hamilton receives his commission as captain of a New York artillery company. Throughout the rest of , Captain Hamilton established himself as a great military leader as he directed his artillery company in several battles in and around New York Live TV.

After making his name with four scientific articles published in , he went on to win worldwide fame for his general theory of relativity and a Nobel Prize in for his explanation of the phenomenon known as the photoelectric effect.

He lived and worked in Princeton, New Jersey, for the remainder of his life. As a child, Einstein became fascinated by music he played the violin , mathematics and science. He dropped out of school in and moved to Switzerland, where he resumed his schooling and later gained admission to the Swiss Federal Polytechnic Institute in Zurich. In , he renounced his German citizenship, and remained officially stateless before becoming a Swiss citizen in While at Zurich Polytechnic, Einstein fell in love with his fellow student Mileva Maric, but his parents opposed the match and he lacked the money to marry.

The couple had an illegitimate daughter, Lieserl, born in early , of whom little is known. After finding a position as a clerk at the Swiss patent office in Bern, Einstein married Maric in ; they would have two more children, Hans Albert born and Eduard born While working at the patent office, Einstein did some of the most creative work of his life, producing no fewer than four groundbreaking articles in alone.

In the first paper, he applied the quantum theory developed by German physicist Max Planck to light in order to explain the phenomenon known as the photoelectric effect, by which a material will emit electrically charged particles when hit by light.

To do this, Einstein introduced his special theory of relativity, which held that the laws of physics are the same even for objects moving in different inertial frames i. A fourth paper concerned the fundamental relationship between mass and energy, concepts viewed previously as completely separate.

Einstein continued working at the patent office until , when he finally found a full-time academic post at the University of Zurich. In , he arrived at the University of Berlin, where he was made director of the Kaiser Wilhelm Institute for Physics. Einstein initially favored construction of the atomic bomb, in order to ensure that Hitler did not do so first, and even sent a letter, dated August 2, , to President Roosevelt encouraging him to initiate a program to create a nuclear weapon.

Roosevelt responded to this by setting up a committee for the investigation of using uranium as a weapon, which in a few years was superseded by the Manhattan Project.

After the war, however, Einstein lobbied for nuclear disarmament and a world government. Along with Albert Schweitzer and Bertrand Russell, he fought against nuclear tests and bombs.

As his last public act, and just days before his death, he signed the Russell-Einstein Manifesto, which led to the Pugwash Conferences on Science and World Affairs. Einstein's latter years were also spent searching for a unified field theory, for a universal force that would link gravitation with electromagnetic and subatomic forces, a problem on which no one to date has been entirely successful.

I have done my share, it is time to go. I will do it elegantly. However, during his life, Einstein participated in brain studies, and at least one biography claimed he hoped researchers would study his brain after he died.

Einstein's brain is now located at the Princeton University Medical Center. In keeping with his wishes, the rest of his body was cremated and the ashes scattered in a secret location. According to The New York Times , the researchers believe it may help explain why Einstein was so intelligent. In , a team of scientists confirmed one aspect of Einstein's general theory of relativity, that the light from a star passing close to a black hole would be stretched to longer wavelengths by the overwhelming gravitational field.

Tracking star S2, their measurements indicated that the star's orbital velocity increased to over 25 million kph as it neared the supermassive black hole at the center of the galaxy, its appearance shifting from blue to red as its wavelengths stretched to escape the pull of gravity.

Prince Albert married his first cousin, Queen Victoria of the United Kingdom, at the age of 20, and after his untimely death at age 42, the queen's memory of him guided her for the next 40 years.

Physicist Enrico Fermi built the prototype of a nuclear reactor and worked on the Manhattan Project to develop the first atomic bomb.

Robert Oppenheimer is often called the "father of the atomic bomb" for leading the Manhattan Project, the program that developed the first nuclear weapon during World War II. Benjamin Franklin is best known as one of the Founding Fathers who never served as president but was a respected inventor, publisher, scientist and diplomat.

Albert Einstein was a physicist who developed the general theory of relativity. He is considered one of the most influential scientists of the 20th century. Albert Einstein's Life in Photos. Olivia Rodrigo —. Megan Thee Stallion —. Bowen Yang —. See More.
