RELATIVITY - Định nghĩa trong Từ điển tiếng Anh
Cách sử dụng
The word 'relativity' means that something is not absolute or fixed, but instead is dependent on other things or factors. For example, the speed of something can only be measured in relation to something else. The theory of relativity, developed by physicist Albert Einstein, explains how time and space can be affected by gravity and motion. In everyday conversation, we might use the word 'relativity' to talk about things being relative to each other, like saying "My salary is high relative to my expenses." It's important to understand the idea of relativity in many fields, including physics, math, and even social sciences like economics and psychology.
