Albert Einstein ( /ˈælbərt ˈnstn/; German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed thegeneral theory of relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics[2][3] and the most influential physicist of the 20th century. While best known for his mass–energy equivalenceformula E = mc2 (which has been dubbed "the world's most famous equation"),[4] he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".[5] The latter was pivotal in establishing quantum theory.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of theelectromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on thegeneral theory of relativity. He continued to deal with problems of statistical mechanicsand quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.[6]

He was visiting the United States when Adolf Hitler came to power in 1933, and did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the U.S., becoming a citizen in 1940.[7] On the eve of World War II, he helped alert President Franklin D. Roosevelt that Germany might be developing an atomic weapon, and recommended that the U.S. begin similar research; this eventually led to what would become the Manhattan Project. Einstein was in support of defending the Allied forces, but largely denounced using the new discovery ofnuclear fission as a weapon. Later, with the British philosopher Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, which highlighted the danger of nuclear weapons. Einstein was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.

Einstein published more than 300 scientific papers along with over 150 non-scientific works.[6][8] His great intellectual achievements and originality have made the word "Einstein" synonymous with genius.[9]


Ebru Gündeş.
- Born on 12.10.1974 in Istanbul. She went to primary school in Ankara. Moving to Istanbul with her family afterwards, Ebru Gündeş had to discontinue her education due to financial impossibility. - The quality of her voice was discovered at her early ages. One of their relatives took Ebru Gündeş and her mother Müjgan Kumartaşlıoğlu to Neşe Demirkat, a partner of Raks Neşe Müzik, then at the stage of foundation. Fascinated as she listened and expressing her desire to introduce this magnificent voice to Turkish people, Neşe Demirkat delivered Ebru Gündeş into the hands of the well-known producer Koral Sarıtaş and of Selçuk Tekay. - Koral Sarıtaş asked Ebru Gündeş to sing behind Emel Sayın, so that she could have stage experience. Gündeş sang behind Sayın for a month and had her first stage experience. - Afterwards, her debut album, “Tanrı Misafiri”, was released in 1994. For those who listened to this song, first introduced by Ajda Pekkan, by Ebru Gündeş’ voice and technique, it was not difficult to embrace her. People who then thought “what a strong voice from such a small body” admired her more and more every day. - Proving her permanence in the music industry with her debut, Ebru Gündeş sold 1.250.000 albums. - Gündeş suddenly fell like a bomb on Turkey, whose success was riveted with her second album “Tatlı Bela”. - Her third album “Ben Daha Büyümedim” was another success following her previous albums. - Her fourth album was titled “Kurtlar Sofrası”. - Fifth was titled “Sen Allah’ın Bir Lütfusun”. - Her sixth album “Dön Ne Olur” is among the top sellers these days. - During the introduction of “Dön Ne Olur” to the press, Ebru Gündeş had a serious sickness. She was hospitalized on December 1, 1999 upon the diagnosis of cerebral hemorrhage and had 2 heavy operations. She was discharged from hospital on December 16, 1999. - In her seventh album in 2001, AHDIM OLSUN, Ebru Gündeş worked with the best lyricists, composers and arrangers of Turkey, again placing herself in the agenda of the music markets with the quality and circulation of the album. - In 2003, she released the album titled ŞAHANE. Gündeş reached her previous success and sales figures with her eighth album, rightfully proud of this outcome. - And now Gündeş has returned with her latest album BİZE DE BU YAKIŞIR, stating that she is living the most productive days of her career and working with all her might.
