Admittedly, I don't know much about physics, but isn't the equation "E=M" just as valid an equation? Energy does equal matter, right?

It's a matter of the amount on both sides of the equation. Just like P ≠ C, but 2P = C, where P is people, and C is a couple.Admittedly, I don't know much about physics, but isn't the equation "E=M" just as valid an equation? Energy does equal matter, right?
As valid as what?

One problem:It's a matter of the amount on both sides of the equation. Just like P ≠ C, but 2P = C, where P is people, and C is a couple.
E = mc² is a mass-energy equivalence. The amount of energy of a particular object is its mass multipled by the speed of light times itself
'fraid ya got it backasswardOne problem:
P = 2C
'fraid ya got it backassward
It's either 2P = C or C = 2p.
Let's try some numbers.
P = the number of people
C = the number of couples
Suppose we have one couple, & want to determine the number of people using your equation.
2P = C yields P = C/2
Substituting C = 1, we find that P = 1/2
But we know that we have 2 people in a couple, not 1/2 a person.
now try P = 2C
Substituting C = 1, we find that P = 2
Lo & behold, this formula let's us correctly determine the quantitative
relationship between the number of people & the number of couples.
QED.
It seems that you intended "2P=C" to mean "2 people equals 1 couple".
But the mathematical expression "2P" means "2 times the variable P", which is the inverse of what you want.
Your error is that "C" refers to couples, not persons.P = 1 person C = 2 persons Therefore C = 2P.
Your error is that "C" refers to couples, not persons.
You're led astray by confusing English with mathematics.
"2P" does not mean "2 persons". It means "2 multiplied by P".
This can be cleared up by considering units (aka dimensions).
The units for P are "persons"
The units for C are "couples"
P/C would be "persons/couple"
The conversion factor is 2 persons/couple.
("Persons" & "couples" are the units of the number)
By analogy, if you want to convert from kg to lbs, the factor is 2.2 lbs/kg
If L is the weight in lbs, & K is the weight in kg, we have...
L =2.2K
If you have 1kg, this formula correctly tells you this is 2.2lbs.
It does not mean that 1 lb is 2.2 kg.
Let's say that it is known that there are 10 couples at a party.
We want to know how many persons this would be.
C = 10 couples
Substituting into P = 2C
P = 2 persons/couple x 10 couples
P = 20 persons
(Note how the "couple" term in the numerator & denominator on the right side cancel out, leaving the term "persons".)
The conversion factor is 2 persons/couple.
I wish I understood any of that....it sounds wicked smart!So we need some kind of thing such that when we use C, and want to get P, this thing, this factor, acts to scale the results and make two different units equivalent? A kind of scaling factor even? If only there were a simple word we had, like facscal, or scalfar, or scalar, or something, to call this that was useful for even more than conversion. Oh well. We shall call it, in honor of this equation, CP-symmetry. It rhymes, and it's not like that's used to refer to anything else.
So, do I get my Nobel now? Or is there like a place I go to collect it?
There's a way mathematicians set up such equations.Right, C is a couple. A couple equals 2 people. Substitute P for people, and you get C = 2P.
Your formula doesn't work because it incorrectly expresses what you say in English.Right, C is a couple. A couple equals 2 people. Substitute P for people, and you get C = 2P.
