This famous two-letter equation, published in 1905, demonstrates that a small amount of matter contains enormous amounts of energy.
Difficulty: EasyThis equation from special relativity shows how inertia increases as an object approaches light speed, becoming infinite at that limit.
Difficulty: MediumThis 1905 derivation showed that a body emitting radiation loses mass according to the formula L/c², predating the famous equation by a few months.
Difficulty: HardThis German city, located in Baden-Württemberg, was the birthplace of Einstein who developed relativity theory.
Difficulty: EasyThis 1907 paper extended the earlier motion theory to include accelerating reference frames, laying groundwork for the later gravity description.
Difficulty: MediumThis connection coefficient in differential geometry describes how vectors change when parallel transported, essential for curved spacetime calculations.
Difficulty: HardThe 1921 Nobel Prize in Physics was awarded for explaining this phenomenon where light ejects electrons from metal surfaces.
Difficulty: EasyThis mathematical tool, developed by Riemann and used by the famous physicist, describes how geometry changes in curved spaces.
Difficulty: Medium
