No, physicists are not mathematically clueless. In fact, mathematics plays a crucial role in the field of physics, and physicists rely on mathematical tools and formalisms to describe and understand the fundamental laws of nature. Mathematical equations and models are used to express physical theories, make predictions, and test hypotheses.
Albert Einstein's statement, "everything is relative," refers to the theory of relativity, which revolutionized our understanding of space, time, and gravity. The theory of relativity, both the special and general theories, introduced a new framework for understanding the behavior of objects in the universe, particularly when they are moving at high speeds or in the presence of strong gravitational fields.
Euler's relation you mentioned is not directly related to Einstein's theory of relativity. The equation you provided appears to be a mathematical expression involving translation, rotation, and complex numbers. Euler's formula, e^(iπ) + 1 = 0, is a well-known mathematical identity that relates exponential, imaginary, and trigonometric functions.
While Einstein's theory of relativity and Euler's mathematical contributions are distinct, they are both significant in their respective domains. Physicists, including Einstein, rely on rigorous mathematical reasoning and tools to develop and articulate physical theories. Mathematics provides physicists with a precise language to describe natural phenomena and formulate relationships between physical quantities.
