paragraph_text: Aner Shalev (born 24 January 1958) is a professor at the Einstein Institute of Mathematics at the Hebrew University of Jerusalem, and a writer.

paragraph_text: General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the "" is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations.

paragraph_text: The quantum revolution of the mid-1920s occurred under the direction of both Einstein and Bohr, and their post-revolutionary debates were about making sense of the change. The shocks for Einstein began in 1925 when Werner Heisenberg introduced matrix equations that removed the Newtonian elements of space and time from any underlying reality. The next shock came in 1926 when Max Born proposed that mechanics were to be understood as a probability without any causal explanation.

paragraph_text: Alfred Kleiner (April 24, 1849 – July 3, 1916) was a Swiss physicist and Professor of Experimental Physics at the University of Zurich. He was Albert Einstein's doctoral advisor or Doktorvater. Initially Einstein's advisor was Heinrich F. Weber.  However, they had a major falling out, and Einstein chose to switch to Kleiner.

paragraph_text: The Max Planck Society and its predecessor Kaiser Wilhelm Society hosted several renowned scientists in their fields, including luminaries such as Otto Hahn, Werner Heisenberg, and Albert Einstein.

paragraph_text: In 1933, Albert and Elsa Einstein emigrated to Princeton, New Jersey, US. In autumn 1935, they moved to a house at 112 Mercer Street, bought that August, but shortly afterwards Elsa developed a swollen eye and was diagnosed with heart and kidney problems. When Elsa was diagnosed, Einstein decided to spend much of his time in his studies. It was stated in Walter Isaacson's book, Einstein: His Life and Universe, that he believed "strenuous intellectual work and looking at God's nature are the reconciling, fortifying yet relentlessly strict angels that shall lead me through all of life's troubles". Thus did Einstein try to escape from his troubles by focusing on work that would distract him from Elsa's dying. Elsa died after a painful illness on December 20, 1936, in the house on Mercer Street.

paragraph_text: "The Heartland Series" was conceived in 1984 to commemorate the 50th anniversary of the founding of the Great Smoky Mountains National Park with a special series celebrating the people and land of the Southern Appalachian Mountains. Actor Bill Landry was hired to host the series. He had previously been a teacher, had written and begun performing a one-man play based on the life of Albert Einstein called "Einstein the Man," and had portrayed a fictional Tennessee River boat captain named "Captain Nat" as part of the Tennessee Valley Authority (TVA) exhibit at the 1982 World's Fair in Knoxville. Following the fair, he had continued to play the role of Captain Nat on a months-long barge tour of the Tennessee, Cumberland, and Mississippi Rivers that TVA conducted for its 50th anniversary.

paragraph_text: The first coronary artery bypass surgery was performed in the United States on May 2, 1960, at the Albert Einstein College of Medicine - Bronx Municipal Hospital Center by a team led by Robert H. Goetz and the thoracic surgeon, Michael Rohman with the assistance of Jordan Haller and Ronald Dee. In this technique the vessels are held together with circumferential ligatures over an inserted metal ring. The internal mammary artery was used as the donor vessel and was anastomosed to the right coronary artery. The actual anastomosis with the Rosenbach ring took fifteen seconds and did not require cardiopulmonary bypass. The disadvantage of using the internal mammary artery was that, at autopsy nine months later, the anastomosis was open, but an atheromatous plaque had occluded the origin of the internal mammary that was used for the bypass.

paragraph_text: Perković culminated her successful junior career by winning gold at the 2009 European Junior Championships with a new national record. A month later, she made the final of the World Championships as the youngest discus thrower in the field.

paragraph_text: The Einsteins were non-observant Ashkenazi Jews, and Albert attended a Catholic elementary school in Munich, from the age of 5, for three years. At the age of 8, he was transferred to the Luitpold Gymnasium (now known as the Albert Einstein Gymnasium), where he received advanced primary and secondary school education until he left the German Empire seven years later.

paragraph_text: Get Your Act Together with Harvey Goldsmith is a Channel 4 television programme in which promoter Harvey Goldsmith is given six months to help revive the fortunes of six entertainment businesses or performers.

paragraph_text: Ri was the first North Korean ever to win a gold medal on vault at the Asian Games, where he performed solidly at the 2006 Asian Games and was the first one for North Korea on that apparatus. He later went on to win a bronze medal on vault at the 2007 World Artistic Gymnastics Championships.

paragraph_text: Left Foot, Right Foot is the second album by Australian hip hop group Hilltop Hoods. It was released in 2001. To promote the album the group performed six or seven shows over a few months.

paragraph_text: The Einstein field equations (EFE; also known as Einstein's equations) comprise the set of 10 equations in Albert Einstein's general theory of relativity that describe the fundamental interaction of gravitation as a result of spacetime being curved by mass and energy. First published by Einstein in 1915 as a tensor equation, the EFE relate local "" (expressed by the Einstein tensor) with the local energy and momentum within that spacetime (expressed by the stress–energy tensor).

paragraph_text: Edwin Einstein (November 18, 1842 – January 24, 1905) was an American politician and a U.S. Representative from New York.

paragraph_text: The Einsteinhaus (Einstein House) is a museum and a former residence of Albert Einstein. It is located on Kramgasse No. 49 in Bern, Switzerland. A flat on the second floor of the house was occupied by Einstein, his wife Mileva Marić, and their son Hans Einstein from 1903 to 1905. The "Annus Mirabilis" papers, which presented Einstein's theory of relativity and contributed substantially to the foundation of modern physics, were written here and published in the "Annalen der Physik". During this time Einstein worked at the Federal Institute of Intellectual Property.

paragraph_text: "Einstein" is a song by American recording artist Kelly Clarkson, from her fifth studio album, "Stronger" (2011). Originally titled as "Dumb + Dumb = You", "Einstein" was written by Clarkson, Toby Gad, Bridget Kelly, and James Fauntleroy II, with Gad handling the production. Lyrically, the song is written in a woman's first-person narrative about her acquiescence and infuriation towards her ex-lover, whom she described in the song as "dumb". Written in wordplay, it uses various mathematical-related equations and topics as rhetorical devices to describe their relationship, notably referencing the German-born physicist Albert Einstein in a metaphorical lyric, which led to the song being named after him.

paragraph_text: The final showdown was between Justin Guarini, one of the early favorites, and Kelly Clarkson. Clarkson was not initially thought of as a contender, but impressed the judges with some good performances in the final rounds, such as her performance of Aretha Franklin's "Natural Woman", and Betty Hutton's "Stuff Like That There", and eventually won the crown on September 4, 2002.
