SUMMARY

The discussion centers on the concepts of quantum numbers and spin in physics, specifically in the context of the Rutherford model of the atom. Participants seek clarification on these terms, with spin being described as a magnetic property of atoms. The term "quantum magnetic number" is suggested as a possible clarification for "quantic number." Resources such as Wikipedia and HyperPhysics are recommended for further understanding.

PREREQUISITES
  • Basic understanding of atomic structure and the Rutherford model
  • Familiarity with fundamental physics concepts such as magnetism
  • Knowledge of quantum mechanics terminology
  • Ability to interpret scientific literature and online resources
NEXT STEPS
  • Research "quantum numbers" and their significance in quantum mechanics
  • Study the concept of "spin" and its implications in particle physics
  • Explore the relationship between spin and magnetism in atoms
  • Review resources on quantum mechanics, such as the Wikipedia page on spin
USEFUL FOR

Students of physics, educators explaining atomic theory, and anyone interested in the fundamental principles of quantum mechanics and atomic behavior.

Hi there! My physics teacher explained us a Ratherford model of atom and used some terms like "spin" and "quantic number". I'm havin trouble with these terms and maybe anybody can explain me the function of "quantic number" and spinnig and give me a basic example.

I just visited some web sites searching for help, but they have more new terms and i can't understand.

Thank you and sorry for my english.

Spin is magnet in atom - not 2. This no good when polarised.

Hi QuantumBend! I don't understand you. You didn't give a good explanation. Can somebody help me to understand these two terms and give me some basic example?

Thank you.
 
Maybe you can show us the website and say what terms you have trouble with.

'quantic number', maybe you mean "quantum magnetic number"?

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
