Relativity is a theory in physics that was first introduced by Albert Einstein in 1905 and later expanded upon in 1915. The theory of relativity fundamentally altered our understanding of space and time by showing that these two concepts are not separate and absolute, but rather are intimately connected and relative to each other.

Relativity & Gear Module What is relativity? And what is Gear module? Relativity is a theory in physics that was first introduced by Albert Einstein in 1905 and later expanded upon in 1915. The theory of relativity fundamentally altered our understanding of space and time by showing that these two concepts are not separate and absolute, but rather are intimately connected and relative to each other. The theory explains how the laws of physics apply to objects in motion, particularly at high speeds or in the presence of massive objects such as stars or black holes. There are two main parts to the theory of relativity: special relativity and general relativity. Special relativity deals with the behavior of objects moving at constant speeds, while general relativity extends the theory to include acceleration and gravity. Gear module, on the other hand, is a term used in mechanical engineering to describe the size of a gear. It refers to the ratio of the gear's pitch diameter to the number of teeth it has. Essentially, the gear module describes the distance between adjacent teeth on a gear, with larger modules indicating larger teeth and smaller modules indicating smaller teeth. Gear modules are an important consideration when designing mechanical systems that use gears, as they can affect the gear's strength, efficiency, and overall performance.
