Albert Einstein (/ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐrt ˈaɪnʃtaɪn] (13px ); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist and philosopher of science. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). He is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation").
Parallels occur when two planets are at the same declination, both in the north or south. They are considered to have the same effect as conjunctions. Contraparallels are when one star in the north and another in the south are at the same declination. They are considered to have the same effect as oppositions.
