The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

55.1K
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.

The Uncertainty Principle

30.2K
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...

The de Broglie Wavelength

32.0K
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...

Estimation of the Physical Quantities01:05

Estimation of the Physical Quantities

6.9K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

Uncertainty in Measurement: Reading Instruments

49.2K
Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

The Bohr Model02:18

The Bohr Model

78.1K
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...

Area of Science:

  • Quantum Mechanics
  • Foundations of Physics

Background:

  • Quantum theory presents interpretational challenges, particularly concerning measurement and observer effects.
  • The wave function collapse is a persistent issue in quantum mechanics interpretations.

Purpose of the Study:

  • To propose a framework that reconciles quantum probabilities with observer experiences.
  • To address inconsistencies in quantum theory using established principles.

Main Methods:

  • Applying Feynman's path integral formulation for probability calculations.
  • Utilizing von Neumann's principle of psycho-physical parallelism to define the observer's role.

Main Results:

  • Feynman's rules enable probability assignment to observer experience sequences without invoking wave function collapse.
  • Von Neumann's principle restricts the observer's role to physical interactions, excluding consciousness from quantum processes.

Conclusions:

  • The combination of Feynman's rules and von Neumann's principle offers a consistent approach to quantum measurement.
  • This framework potentially resolves paradoxes related to the observer in quantum mechanics.
