Essay on quantum theory
WebQuantummechanics is one of the major revolutions in 20th century Physics. It is probably the closest science has come to a fundamental description of the underlying nature of reality. And yet it is totally bizarre—it flies in the face of all our intuition and common sense. WebSep 1, 2024 · Summary —This essay tells the story of quantum theory and argues that we need to understand it so we can finally come to know the ultimate nature of reality.. …
