1 What Is the Measurement Problem Anyway? Introductory Reflections on Quantum Puzzles
نویسنده
چکیده
“Can the quantum-mechanical description of physical reality be considered complete?” It is perhaps not coincidental that this question, the title of Einstein’s famous onslaught on quantum mechanics [1], was echoed verbatim in the title of Bohr’s reply [2]. Although Bohr opted for a “Yes”, today even his ardent followers (see Wheeler below) believe that quantum mechanics is not the last word. Someday, we all believe, a new theory will revolutionize physics, just as relativity and quantum mechanics did at the dawn of the 20th century. It will include its two parent revolutions as special cases, just as classical mechanics has been comfortably embedded within relativity theory and less comfortably within quantum mechanics. What this theory will tell us about the nature of reality is anybody’s guess, but John Wheeler has vividly captured its most immediate feature [3]:

متن کاملDesigning a quantum genetic controller for tracking the path of quantum systems
Based on learning control methods and computational intelligence, control of quantum systems is an attractive field of study in control engineering. What is important is to establish control approach ensuring that the control process converges to achieve a given control objective and at the same time it is simple and clear. In this paper, a learning control method based on genetic quantum contr...
متن کاملQuantum Theory: Exact or Approximate?
Quantum mechanics has enjoyed a multitude of successes since its formulation in the early twentieth century. It has explained the structure and interactions of atoms, nuclei, and subnuclear particles, and has given rise to revolutionary new technologies. At the same time, it has generated puzzles that persist to this day. These puzzles are largely connected with the role that measurements play ...
متن کاملIntroductory lecture on Bohmian mechanics
Bohmian mechanics is a theory of quantum phenomena based on a particle picture. On a fundamental level, it explains the world around us in terms of point particles that move on deterministic paths. When used to describe experimental situations, Bohmian mechanics yields the textbook formalism of quantum mechanics, and can therefore be considered as an explanation of the axioms of standard quantu...

The aesthetics of “everyday experience” is made by a paradigm that defines the duality of the Elite art/low-class art by focusing on the art of the majority/minority, based on the desire of the urban middle class, It has been put as the art of the people in opposition to the art of avant-garde. The study is based on reflections on possibility of finding the main origin between the art of the ma...
