Quote by Albert Einstein
A moving object appears to shrink in the direction of motion as seend by a stationary observer.
Summary
The quote describes the phenomenon known as the "Lorentz-FitzGerald contraction" or "length contraction." It states that when an object is in motion relative to a stationary observer, it will appear smaller in the direction of motion. This is due to the effects of special relativity, where the dimensions of an object shorten as its speed approaches the speed of light. This contraction is not physically a change in size, but rather a visual perception resulting from the relative motion between the observer and the moving object.
