Discussion Overview

The discussion revolves around the proposition that "2+2=5" might hold true under certain conditions in physics, particularly when considering large values or approximations. Participants explore the implications of this statement in both mathematical and physical contexts, questioning its validity and relevance.

Discussion Character

  • Debate/contested
  • Mathematical reasoning
  • Conceptual clarification

Main Points Raised

  • Some participants question the meaning of "large values of 2," suggesting it is nonsensical or a joke.
  • Others propose that if parameters exceed the value of 2, the sum could theoretically approach 5, though they note the equation itself is meaningless.
  • A participant argues that 2 is a fixed number and cannot take on a "large" value.
  • One participant introduces a mathematical framework involving cross products and linear time invariant systems, suggesting that under certain limits, "2+2=5" could hold.
  • Another participant humorously suggests that if 3 is considered a large value of 2, then "3 + 3 = 5" could be interpreted to support the claim.
  • Further technical discussions reference invariant approximation tensors and the convergence of series, indicating a complex interplay of mathematical concepts.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the statement "2+2=5," with some dismissing it as a joke while others explore its implications under specific mathematical frameworks. No consensus is reached regarding its applicability in physics.

Contextual Notes

The discussion includes various assumptions about mathematical definitions and the nature of numbers, as well as unresolved mathematical steps related to the proposed frameworks.

some people says that for the large values of 2
2+2=5
is it really true. I mean what is the physics behind this equation.
yours sincerely,
sancho,

Large values of 2?? Huh?? [itex]2+2\neq 5[/itex]

sancho,

That is an old joke. It's not true. "Large values of 2" means nothing.
 
but 2 has large value sometimes. why not?
sometimes some experimental parameters also have large values?

Yes, and if it has a value greater than two, it just might sum with itself to 5. The actual equation is meaningless though
 
But 2 is not a "parameter"-- it is a number, and thus takes only the value 2!
 
There is no physics nor is there any math behind that statement. It is simply an old joke.
 
Well, when you take the cross product of the transformation vector in R^n and assume a linear time invariant system then the approximation that 2+2=5 holds in the limit that alpha approaches infinity.

Why not? Because 2 isn't a balloon in the shape of number 2 which gets large sometimes because we blow it up some more. :biggrin:

You forgot about the key assumption about the invariant approximation tensor and about the uniform convergence of the gamma-series generated by non-uniform hybrid Laplace members.

2.3+2.3=4.6 = 5 for 1 sig dig? lol is that maybe what he is getting at? In any case I don't think there is any physics behind this equation

(This is a desperate attempt to try to understand what he meant by "large values of 2" lol)

Ah yes, of course. Only when the skew-symmetric, non-invertible mass-matrix is in place, or det(A)=cross(J,F).

:approve: Damn.. forgot about that. Good spot, cyrus.

Which implies an obvious isomorphism between Schmidt's dihedral group and the group od positively definite inertia matrices spanned by Van der Haagen's dual basis.

This would be the complete frame-set of the problem.

Now we're talking.

I think what they are getting at is that since 3 is a large value of 2 and 3 + 3 = 5 (for small values of 3), therefore 2 + 2 = 5.

Exactly. A typical example of diophantine isoparallelism induced by general invariancy.
