Schrödinger’s cat is not a real experiment, but a thought experiment, which means it is only imagined and not actually performed. Erwin Schrödinger came up with it to show the absurdity of applying quantum mechanics to everyday objects, such as cats. He did not intend to suggest

In June 1926 Max Born submitted a paper on electron scattering in which he proposed, for the first time, that Schrödinger's wave-function does not describe a physical wave but determines the probability of where the electron goes. In the main text he wrote that the amplitude http

The best life is the one in which the creative impulses play the largest part and the possessive impulses the smallest. Without effort and change, human life cannot remain good. It is not a finished Utopia that we ought to desire, but a world where imagination and hope are alive

Cavendish's experiment is described in most textbooks as measuring the gravitational constant G. It did not; the paper is about determining the density of the Earth, and a 2025 survey of 84 textbooks found the error runs right through the 20th century. https://t.co/y0Zd8lSTbo
