Discussion Overview

The discussion revolves around the expression G^(ε0μ0) in MATLAB, where participants explore whether this expression equals 1, considering the implications of the constants involved and the precision of numerical calculations.

Discussion Character

  • Exploratory
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant observes that G^(ε0μ0) appears to equal 1 when calculated in MATLAB with high precision, questioning if this has been noted or investigated by others.
  • Another participant raises the question of whether the constants involved (G, ε0, μ0) are irrational or transcendental, suggesting that a rational number raised to a non-zero power cannot equal 1.
  • A different participant challenges the validity of the expression, stating that an exponent must be unitless and that the result being approximately one is likely due to the choice of units, noting that in other systems the result would differ significantly.
  • One participant discusses the conditions under which a^b can equal 1, emphasizing that either the base must be 1 or the exponent must be 0.
  • Another participant humorously comments on the implications of the observation, suggesting it could unify gravity with electromagnetic theory, while also questioning the utility of such precision in calculations.
  • A later reply expresses skepticism about the validity of the claim, indicating that similar results can occur with small numbers on calculators.
  • One participant requests that those who doubt the validity of the discussion refrain from posting, indicating a desire to maintain focus on the topic.

Areas of Agreement / Disagreement

Participants express differing views on the validity of the expression G^(ε0μ0) equaling 1, with some questioning the mathematical basis and others suggesting it may be a numerical artifact. No consensus is reached on the implications of the findings.

Contextual Notes

Limitations include the dependence on the choice of units and the precision of numerical calculations in MATLAB, which may affect the interpretation of the results.

I've got MATLAB set to several(about 20) decimal places and I noticed something.

G^(E0M0)=1 seemingly exactly.

That is the gravitational constant G raised to the quantity of the permittivity constant multiplied by the constant of permeability.

That is approximately
(6.67428E-11)^((1.2566370614359E-6)*(8.854187815E-12))=1.0000000000.

Now obviously I know that that doesn't necessarily mean anything because the numbers are so small, but has anyone ever noticed it or commented on it or at least investigated it?

Keep in mind that those are just approximations for the physical constants.

Are those constants irrational and transcendental!

That would be the major question. Since any rational number raised to a power OTHER THAN ZERO cannot be 1, than it is just a case of running out of decimal places. But a transcendental number raised to a transcendental exponent could hypothetically equal 1 I believe. If someone is aware of a proof showing otherwise, please tell me.

This expression doesn't make a bit of sense. An exponent must be unitless for an expression to be valid. That the result is approximately one is just a fluke of the of the choice of units. In other systems (e.g. "natural units", [itex]\epsilon_0=1, \mu_0=1[/itex]) the result of this expression is not even close to unity.

To show that the number is not one, just take the log of the expression:
[tex]\log_{10}\left((6.67428\cdot10^{-11})^{1.2566370614359\cdot10^{-6}*8.854187815\cdot10^{-12}}\right)= -9.64327467\cdot10^{-17}[/tex]

To set Matlab to twenty decimal places you need to do a lot more than set the format. You need to use variable-precision arithmetic throughout. In particular, you need to convert the double precision numbers used the expression to variable-precision values.

You want to find two numbers [itex]a[/itex] and [itex]b[/itex] such that [itex]a^b=1[/itex]. Take the log of this expression: [itex]b\log a = 0[/itex]. The only way to arrive at such a result is if either [itex]b=0[/itex] or [itex]a=1[/itex].
 
Congratulations, you have successfully unified gravity with electromagnetic theory :approve:


Seriously though, what are you going to do with 20 decimal places?! Sig figs are an important rule to keep in mind.
 
HaHa

Yeah, I saw that on the web awhile ago and I was startled at first, but quickly realized that it was just a calculator thing and the claim . I was just hoping that a few "wows" would post or something. But I guess only alert people posted. I forget what the site is, but it has a whole list of phony unified field theory and Riemann hypothesis proofs and so forth.

Oh one more thing, just about any exponential relation between numbers that small will surely yield one on nearly all calculators.
 
If you already know it's crap, please don't post it here. Thanks.
