Electron Orbital Model01:18

Electron Orbital Model

67.6K
Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual orbitals found within the subshells.
The first shell is closest to the nucleus, and it has only one subshell with a single spherical orbital called the...

The Bohr Model

67.8K
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 Quantum-Mechanical Model of an Atom

47.1K
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...

First Law: Particles in One-dimensional Equilibrium01:10

First Law: Particles in One-dimensional Equilibrium

6.9K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

Equilibrium Conditions for a Particle01:23

Equilibrium Conditions for a Particle

2.4K
When an object is in equilibrium, it is either at rest or moving with a constant velocity. There are two types of equilibrium: static and dynamic. Static equilibrium occurs when an object is at rest, while dynamic equilibrium occurs when an object is moving with a constant velocity. In both cases, there must be a balance of forces acting on the object.
To understand the concept of equilibrium, let us first consider the forces acting on an object. When different forces act on an object, they can...

Actor-Observer Effect01:23

Actor-Observer Effect

580
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

Area of Science:

  • Quantum mechanics
  • Foundations of physics
  • Quantum information theory

Background:

  • Wigner's Friend paradoxes highlight contradictions in quantum theory.
  • Existing no-go theorems rely on specific metaphysical assumptions.

Purpose of the Study:

  • To present a constructive approach resolving quantum theory contradictions.
  • To re-evaluate assumptions in Wigner's Friend scenarios.

Main Methods:

  • Modeling quantum observers using quantum circuits.
  • Developing a framework based on agents making true statements.
  • Applying methodology to the Frauchiger-Renner paradox.

Main Results:

  • All agents' statements are shown to be true and consistent.
  • Quantum theory's apparent contradictions are resolved.
  • Identified an incorrect implicit assumption in prior no-go theorems.

Conclusions:

  • A constructive approach can resolve paradoxes in quantum mechanics.
  • Quantum observers can be modeled consistently within quantum circuits.
  • Revisiting agent behavior assumptions is key to understanding quantum theory.
