All knowledge starts with curiosity
This curiosity is probably Einstein's most defining quality, after his intelligence.
His love of physics started as a boy when he was given a compass and fascinated by the idea that the needle moved because of an unseen force.
Curiosity was his motivation for learning physics..
at the age of 26 in 1905—the same year he published four groundbreaking articles in physics.
Even as a teenager, Einstein had already developed a profound mistrust of authority..
1915 Einstein publishes the general theory of relativity. 1916 The astronomer Karl Schwarzschild (1873–1916) publishes the first exact solution to the Einstein field equations, which were later fundamental to the description of black holes.Oct 14, 2015.
Einstein learned physics, not by dutifully attending classes, but by obsessively playing with the ideas and equations on his own.
Doing, not listening, was the starting point for how he learned physics..
He received a bachelor's degree from Swiss Federal Polytechnic in 1900 and a PhD from the University of Zurich in 1905.
Einstein's career famously began at a patent office in Bern, Switzerland, where he had time to ponder big questions in physics after reviewing patent applications..
Einstein therefore attended education institutions near-continuously from the age of 5 to 26, with only a brief gap in 1894/1895 (aged 15/16) whilst his family moved around Europe.
Of those 21 years of education, 9 of them were at a university studying physics..
Einstein almost immediately applied his gravity theory to the universe as a whole, publishing his first cosmological paper in 1917.
Because he was not well acquainted with recent work in astronomy, he assumed that the universe was static and unchanging..

At age 21, Einstein earned his physics teaching diploma.
Einstein graduated with his teaching diploma from the Z\xfcrich Polytechnic, Switzerland in 1900.
Though Einstein showed exceptional skill in his theoretical physics courses, he scored lower in his math courses..
In 1896, at age 17, Einstein entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics.
A few years later, he gained his diploma and acquired Swiss citizenship but was unable to find a teaching post..
Born on 14 March 1879 in Ulm, Germany, Albert Einstein was the most impactful physicist of the 20th century.
He received a bachelor's degree from Swiss Federal Polytechnic in 1900 and a PhD from the University of Zurich in 1905..
Einstein's career sent him to multiple countries. He earned his doctorate from the University of Zurich in 1905 and subsequently took on professor positions in Zurich (1909), Prague (1911) and Zurich again (1912). Next, he moved to Berlin to become director of the Kaiser Wilhelm Physical Institute and a professor at the University of Berlin (1914)..
Einstein was born on March 14, 1879, in Ulm, Germany, a town that today has a population of just more than 120,000. There is a small commemorative plaque where his house used to stand (it was destroyed during World War II). The family moved to Munich shortly after his birth, according to the Nobel Prize website, and later to Italy when his father f.
Harvey's 1985 study authors reported that Einstein's brain had a higher number of glial cells (those that support and insulate the nervous system) per neurons (nerve cells) than other brains they examined. They concluded that it might indicate the neurons had a higher metabolic need — in other words, Einstein's brain cells needed and used more ener.
Einstein's legacy in physics is significant. Here are some of the key scientific principles that he pioneered: Theory of special relativity: Einstein showed that physical laws are identical for all observers, as long as they are not under acceleration. However, the speed of light in a vacuum is always the same, no matter at what speed the observer .
Albert Einstein profoundly changed physics and ideas about space and time
(Image credit: ,Bettmann / Contributor via Getty Images) Albert Einstein is often cited as one of the most influential scientists of the 20th century
His work continues to help astronomers study everything from gravitational waves to Mercury 's orbit
Einstein 's many visionary scientific contributions include ,the equivalence of mass and energy (E=mc^2), how the maximum speed limit of light affects measurements of time and space ( special relativity ), and a more accurate theory of gravity based on simple geometric concepts ( general relativity )

Albert EinsteinaɪEYEN-styne German: ,[ˈalbɛɐt ˈʔaɪnʃtaɪn]; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely held to be one of the greatest and most influential scientists of all time
Not long after Einstein published GR, researchers realized the theory predicts that the universe changes in time
Observations in the 1920s found that prediction was true: the universe is expanding, with galaxies moving away from each other
Using GR, cosmologists found the cosmos had a beginning, and was once hotter and denser than it is today
Originally designated HEAO 2, the Einstein Observatory was the second part of a trio of space observatories in NASA’s High Energy Astronomy Observatory Program (HEAO) in the late 1970s and early 1980s
The other two spacecraft were HEAO 1 and HEAO 3, designed to observe gamma rays and the electrically charged particles known as cosmic rays
Model of the Universe proposed 1932
The Einstein–de Sitter universe is a model of the universe proposed by Albert Einstein and Willem de Sitter in 1932.On first learning of Edwin Hubble's discovery of a linear relation between the redshift of the galaxies and their distance
Einstein set the cosmological constant to zero in the Friedmann equations
Resulting in a model of the expanding universe known as the Friedmann–Einstein universe.In 1932
Einstein and De Sitter proposed an even simpler cosmic model by assuming a vanishing spatial curvature as well as a vanishing cosmological constant.In modern parlance
The Einstein–de Sitter universe can be described as a cosmological model for a flat matter-only Friedmann–Lemaître–Robertson–Walker metric (FLRW) universe.
Quantities describing probability of absorption or emission of light
Einstein coefficients are quantities describing the probability of absorption or emission of a photon by an atom or molecule.The Einstein A coefficients are related to the rate of spontaneous emission of light
And the Einstein B coefficients are related to the absorption and stimulated emission of light.Throughout this article
light refers to any electromagnetic radiation
Not necessarily in the visible spectrum.
