Discussion Overview

The discussion revolves around the calculation of charge, specifically focusing on how the charge of fundamental particles like electrons and protons is determined. Participants reference historical experiments and methods, including the mass/charge ratio in mass spectrometry and Millikan's oil drop experiment.

Discussion Character

  • Exploratory, Technical explanation, Historical

Main Points Raised

  • One participant inquires about the methods used to calculate the charge of electrons and protons, specifically questioning the role of mass/charge ratios in mass spectrometry.
  • Another participant mentions Millikan's oil drop experiment as a historical method for determining the charge of an electron, expressing uncertainty about how the current value was derived.
  • A link to a Wikipedia article on the oil drop experiment is shared for additional context.
  • There is a follow-up post thanking the previous contributor for the information provided.
  • A repeated inquiry about charge calculation is made, alongside an unrelated request for information about a game, indicating a potential distraction from the main topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the methods for calculating charge, and there are multiple references to different historical experiments without resolving which is the most accurate or preferred method.

Contextual Notes

Some assumptions about the accuracy and relevance of historical experiments are not fully explored, and the discussion includes a mix of focused inquiries and off-topic comments.

How charge is calculated? for example,how we found the charge of an electron or proton?
is it using mass/charge ratio in mass spectrometer?
 
Physics news on Phys.org
Thanks for the info..

Yeah, i think so, :wink: http://www.internetgameservice.com/pirates-of-the-burning-sea-gold-potbs.php can you give me some info about the game gold?/ i don't think this website is good enough for me.
