The Uncertainty Principle04:08

The Uncertainty Principle

27.0K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

The Bohr Model

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as...

The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Area of Science:

  • Quantum Mechanics
  • Philosophy of Science

Background:

  • The interpretation of Heisenberg's uncertainty principle and the meaning of "cannot" in quantum mechanics remain debated.
  • The nature of time in quantum mechanics has received less attention compared to classical and relativistic physics.

Purpose of the Study:

  • To investigate the relationship between possibility and time within a realist interpretation of quantum mechanics.
  • To demonstrate that the concepts of possibility and actuality are intrinsically linked to distinct temporal notions in the quantum realm.

Main Methods:

  • Philosophical analysis of quantum mechanical principles.
  • Exploration of realist interpretations of quantum mechanics.
  • Conceptual distinction between parameter-time and event-time.

Main Results:

  • The term "cannot" in quantum mechanics may not signify absolute impossibility but rather a nuanced relationship between observables.
  • Possibility and actuality are presented as irreducible modes of being.
  • Two distinct concepts of time, parameter-time and event-time, are identified and correlated with possibility and actuality.

Conclusions:

  • A realist interpretation of quantum mechanics reveals a strong connection between the concepts of possibility and time.
  • The distinction between parameter-time and event-time offers a new perspective on quantum temporal dynamics.
  • Understanding these temporal distinctions is crucial for a comprehensive interpretation of quantum phenomena.
