SUMMARY

The discussion centers on the fundamental nature of electric charge, specifically regarding quarks and their properties. Protons consist of up and down quarks, with up quarks having a charge of +2/3 and down quarks a charge of -1/3. The assignment of positive and negative charges is arbitrary, as physics allows for redefinition without altering the underlying principles. Quantum field theory can describe interactions between charges, but it does not provide answers to the "why" behind these properties.

PREREQUISITES
  • Understanding of atomic structure, including protons, neutrons, and electrons.
  • Basic knowledge of quark properties and their charges.
  • Familiarity with the concepts of electric charge and its definitions.
  • Introduction to quantum field theory and its implications in particle physics.
NEXT STEPS
  • Research the properties of quarks in the Standard Model of particle physics.
  • Explore the implications of charge redefinition in theoretical physics.
  • Study quantum field theory and its role in describing particle interactions.
  • Investigate the philosophical implications of "why" questions in physics.
USEFUL FOR

Students of physics, educators in particle physics, and anyone interested in the fundamental properties of matter and charge interactions.

okk I am sorry if I am in the wrong category but i didnt really know where to post this question.
Ok so what makes positive... positive? I know that atoms are made of nutrons, protons and electrons, and protons are made of up and down quarks which have a positive charge of 2/3 and a negative charge of -1/3... so what makes that quark have a positive property? what is it that attracts negative to positive? how can something only have half a charge? I am sorry if this is something really basic I've just been wondering this a while now and i can't find it anywhere!

so what makes that quark have a positive property?
That is unknown. The laws of physics just describe the experimental results.
If you just care about positive<->negative: The definition is arbitrary, we could assign "negative" values to up-quarks and "positive" values to electronsm, without changing physics. You could even name them "good charge" and "bad charge", or whatever.
what is it that attracts negative to positive?
Quantum field theory can describe it, but physics cannot answer "why" questions.
how can something only have half a charge?
That is just a matter of definition. You could assign -1 charge to down-quarks, +2 charge to up-quarks and -3 charge to electrons. You would have to change the prefactors of some constants, but physics would stay the same.
