Discussion Overview

The discussion revolves around identifying famous physicists associated with specific equations, particularly in the context of quantum physics and electrical engineering. Participants explore connections between physicists and their contributions to various equations, including those related to energy and power in resistors.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant poses a puzzle about connecting physicists to specific equations, indicating they know the answers for some variables.
  • Another participant hints that the variable "z" relates to quantum physics through the constant "h," prompting associations with physicists like Planck, Bohr, Einstein, and Heisenberg.
  • A participant confirms that "z" corresponds to Planck's law, suggesting a connection to Planck.
  • Concerns are raised about the historical attribution of the formula for power/energy used in a resistor, with a participant expressing uncertainty about whether Ohm was the first to present it.
  • Another participant reiterates their uncertainty regarding the historical precedence of the resistor power formula, mentioning its relation to energy and the unit of energy being Joule.
  • A follow-up question seeks clarification on who first presented the resistor power formula in various forms, indicating a desire for historical context.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the historical attribution of certain equations and their associated physicists, indicating that multiple competing views remain on the topic.

Contextual Notes

Limitations include unresolved historical details about the first presentation of the resistor power formula and the dependence on definitions of energy and power in different contexts.

I have got this puzzel - who do you connect with these equations?
I know the answers to a, b, v, w, y

Hint for "z": It has the constant "h" in it, which appears only in equations that have to do with quantum physics. Who do you associate with quantum physics?
 
h - is Planck's constant. But I associate Bohr, Einstein, and Heisenberg as well with quantum physicics
 
OK - z was Planck's law :-p
 
I think, I'm sure about all except the formula for the power/energy used in a resistor. I guess this has also been Ohm, but I'm not sure who was historically first.

The equation involves time, so is definitely energy (aka work).

Unit of energy = Joule http://en.wikipedia.org/wiki/James_Prescott_Joule

Sure, but who has given this formula first, be it in the integrated form or as the power, in any of the equivalent forms, [itex]P=U I=R I^2=U^2/R[/itex]?
