Quote by Albert Einstein
A theory is the more impressive the greater is the simplicity of its premises, the more different are the kinds of things it relates and the more extended the range of its applicability.
Summary
This quote suggests that the credibility of a theory depends on three factors: the simplicity of its assumptions, the diversity of subjects it connects, and the extent of its practical application. A theory is deemed impressive when its foundational principles are presented in a straightforward manner. Furthermore, if it can establish connections between various kinds of phenomena and prove applicable to a wide range of situations, it gains even more validity. In essence, the quote emphasizes that a powerful theory possesses simplicity, breadth, and versatility in its explanatory power.
