    Because some people refer to you as "She", that's all.
  • E = mc²
    Well, you have the option of explaining the meaning of Einstein's formula, then.
  • E = mc²
    Calling it a "logical conjunction" is a category error. Logical conjunctions don't have numerical values.flannel jesus

    They do if if they're tautologies.
  • E = mc²
    ↪Arcane Sandwich
    the same property. So kinetic and potential are the same as each other.

    That's just objectively false
    flannel jesus

    As opposed to what? Subjectively false?
  • E = mc²
    The only two options I can see are "plus", or saying "this numerical value is equal to kinetic energy; also it's equal to potential".

    What other options are there?
    flannel jesus

    It's a logical conjunction. This isn't rocket science, it's propositional logic, dude.

    When I calculate the numerical value of e, then you say "that's kinetic and potential energy", what's and? — flannel jesus


    It means that they're the same property: E.

  • E = mc²
    ↪Arcane Sandwich
    that's not an explanation. You cannot use the symbol you're defining in the definition.
    flannel jesus

    Why not?

    That's like you asking me what an apple is, and I say "it's the thing you're eating when you're eating an apple".flannel jesus

    Which is a perfectly OK thing to say.

    What's &? What's And?flannel jesus

    It's a logical conjunction. This isn't rocket science, it's propositional logic, dude.

    When I calculate the numerical value of e, then you say "that's kinetic and potential energy", what's and?flannel jesus

    It means that they're the same property: E.
  • E = mc²
    You don't have to be embarrassed. Just say what it meansflannel jesus

    See .
  • E = mc²
    ↪Arcane Sandwich
    I don't think there's any possible interpretation of "and" which would make "kinetic and potential energy" the thing that e refers to in Einstein's equation.
    flannel jesus

    Oh, and you expect me to do something about that?

    You've told me and doesn't mean plus but you're refusing, perhaps out of embarrassment, to say what "and" does meanflannel jesus

    I already told you what it means, it means:

    Energy (potential & kinetic) = physical mass, defined as a Newtonian force, multiplied by the speed of light, squared.
  • E = mc²
    Plus seemed like a more reasonable interpretation, I was trying to be charitable with that.flannel jesus

    Let's just say that what you're selling as medicine is just snake oil, how about that?
  • E = mc²
    explain what you mean?flannel jesus

    About what?
  • E = mc²
    That would imply kinetic energy is always equal to potential energy, which is just simply not true, so I didn't think you could possibly mean that.flannel jesus

    :roll:

    Then why did you even ask the question in the first place?
  • E = mc²
    Do you mean e equals the kinetic energy, and also separately it equals the potential energy?flannel jesus

    No, I don't. Have I actually said that? No, I didn't.
  • E = mc²
    ↪Arcane Sandwich
    how does that apply to a numerical value that you get for e from Einstein's equation? "This numerical value is equal to kinetic AND potential energy"?
    flannel jesus

    :roll:

    If I tell you that a + b is an algebraic formula, would you object to that by saying "a and b are letters of the English language?"
  • E = mc²
    ↪Arcane Sandwich
    originally I just wanted to know if it was meaningful to you, beyond just a bunch of symbols you've been told are "true" when you put them in that order.
    flannel jesus

    :roll:

    Through much deliberation, I think I've discovered the answer.flannel jesus

    Good for you :up:
  • E = mc²
    I don't know what "and" could possibly mean other than plus in this context anyway.flannel jesus

    It could mean the logical "and". As in, "p and q".
  • E = mc²
    What was your point, again? About the truth of Einstein's formula?
  • E = mc²
    Either way you phrase it is equally incorrect.flannel jesus

    What you just said is a contradiction.
  • E = mc²
    ↪Arcane Sandwich
    and, plus, this seems pedantic to me.
    flannel jesus

    Oh, it's pedantic? So you would say that 2 + 5 is the same formula as 2 - 5?
  • E = mc²
    kinetic and potential energy, dude. In Newtonian terms. It's super simple. You already know this. — Arcane Sandwich


    You didn't say that it does? Are you kidding?
    flannel jesus

    Where did I say "plus"? Oh that's right, I didn't say it. You said it:

    Also you're wrong about what the e means, it doesn't mean kinetic plus potential.flannel jesus
  • E = mc²
    Also you're wrong about what the e means, it doesn't mean kinetic plus potential.flannel jesus

    I never said that it does. There's no difference between kinetic and potential energy. Just as there's no difference between energy and heat. It's really just the same thing: energy. And that, is equal to mass, times the speed of light, squared. And that is a property that every material object has.
  • E = mc²
    Like what? If you can't provide any actual examples of what you just said there, then you just said a bunch of nonsense.
  • E = mc²
    So what's your point?
  • E = mc²
    A = dx + ey - z^3 true or false?flannel jesus

    How would I know? I'd have to calculate it.
  • E = mc²
    Something that's just a formula has no truth value whatsoever.flannel jesus

    I disagree. For all formulas, there are three kinds: those that are T, those that are F, and those that can be either T or F, depending on the case.

    It doesn't make sense to call a formula "true".flannel jesus

    It has a truth value: T or F.
  • E = mc²
    It refers to the objects "rest energy", which is a different figure altogether.flannel jesus

    It's the same as rest mass. And since you have rest in both cases, you can simplify it, so that you're actually talking about energy and mass. Again, this isn't rocket science.

    You don't know what it means.flannel jesus

    Ok, then why don't you tell me what it means?

    And that's okay, but I think you could have a more interesting exploration of it all if you stopped calling it obvious and acknowledged that a bit.flannel jesus

    Acknowledge what? Its a formula, dude. There is nothing to understand about it!
  • E = mc²
    Of course it does. Scientists distinguish many different kinds of energy. But's the same type of property, at the end of the day: E.
  • E = mc²
    kinetic and potential energy, dude. In Newtonian terms. It's super simple. You already know this.
  • E = mc²
    My question isn't a question of curiosity, it's a question of meaning. It's not meaningful for you to say e equals MC squared if you don't know what it's the energy of.flannel jesus

    It's the energy of an ordinary object, such as a stone or a table, for example.

    What are you calculating?flannel jesus

    You're calculating the relationship between energy, mass, and the speed of light.

    The energy, fine, the energy of what?flannel jesus

    Again, the energy of an ordinary object, such as a stone, or a table, for example.

    If you don't know,flannel jesus

    Yet I do know. And so do you. It's super obvious.

    then you saying it's "true" is a lot like a kid saying his dad is Fargleflannel jesus

    Whatever, man. When someone asks me if a=a is true, I say yes. When they ask me if a=b is true, I say that it depends on the case. And when someone asks me if a=a is false, I say no. And when they ask me if a=b is false, I tell them that it depends on the case.
  • E = mc²
    Ok, so what's the most reasonable alternative, then?
  • E = mc²
    What if I told you to ask Einstein himself? Then what?
  • E = mc²
    the energy OF WHAT?flannel jesus

    Again, why don't you tell me?
  • E = mc²
    One of the answers you actually could have given that would have been reasonable, but which you neglected, would have been to specify units.flannel jesus

    Einstein's formula, from a purely mathematical point of view, does not require them.
