tính tương đối
/ˌreləˈtɪvəti//ˌreləˈtɪvəti/The word "relativity" was coined by the German physicist Hermann Minkowski in the early 1900s to describe the idea that the laws of physics are the same for all observers in uniform motion relative to one another. This concept was later developed and popularized by Albert Einstein, who used it to explain phenomena such as time dilation and length contraction. Minkowski introduced the term "relativity" in a 1907 lecture, where he discussed the geometric nature of spacetime and the concept of "relativity of simultaneity." Einstein built upon Minkowski's work and introduced the concept of special relativity in 1905, followed by general relativity in 1915. The term "relativity" has since become synonymous with Einstein's theory and has been widely used in physics and philosophy to describe the idea that physical phenomena are relative to the observer's frame of reference.
