In summary, the conversation discusses the use of unconventional ideas in exploring mathematical logic and the relationship between dimensional analysis and Fermat's Last Theorem. It is noted that as n increases, the right-hand side of the equation 3^n + 4^n = 5^n becomes progressively larger, leading to the conclusion that at n=infinity, the principle of holism is vindicated. It is also mentioned that when n is less than 2, the reverse happens, and when n=0, the quantum nature of number becomes apparent. The conversation then shifts to discussing the volumes of an n-sphere and an n-cube, and the question of which spatial dimension would make their volumes equal.

What is done in the following might be considered as “not mathematical.” Nevertheless we must be allowed to use crazy ideas if only for the sake of exploring the uncharted domains of human mathematical logic.

This is not to prove again the famous math problem called Fermat’s Last Theorem. The proof was done by Andrew Wiles in the 1990s. But use it in relation to dimensional analysis.

The algebraic equation is [tex]a^n +b^n = c^n[/tex] The exponential number n, in our discussion, is the dimension. For the case where n=2, the equation is called the Pythagorean theorem and its solutions are the Pythagorean triples. For our purpose, we only need one of these triples: a=3, b=4, c=5. The equations becomes [tex]3^2+4^2=5^2[/tex]. The left-hand (LHS) side is always equal to the right-hand side (RHS).

When n=3, the RHS is bigger than the LHS. When n=4, the RHS is even bigger than the LHS. It can be noted that, as n increases from 2 to infinity, the RHS becomes progressively bigger and bigger. We can make the conclusion that at n=infinity, the principle of holism is vindicated. The whole is greater than the sum of its parts. And no matter how many parts are added together, the sum is always less than the whole.

Likewise, it can be shown that if n is less than 2, the reverse happens, the RHS becomes smaller than the LHS. And if we allow n to take on fractional value, the RHS becomes progressively smaller and smaller than the LHS. So that when n=0, the quantum nature of number becomes apparent (1 + 1 > 1).

No. The only conclusion that can be drawn is that [itex]3^n +4^n = 5^n[/itex] is not true for [itex]n\neq 2[/itex].

Thanks for all your replies.

For the next discussion is that of an n-sphere and an n-cube.
What spatial dimension makes their volumes equal?
 

1. What is "Dimension by Exponentiation"?

"Dimension by Exponentiation" is a mathematical concept that involves raising a physical quantity to a certain power or exponent in order to determine its dimension. This is often used in dimensional analysis to convert between units or determine the dimensions of a derived quantity.

2. How is "Dimension by Exponentiation" used in scientific research?

"Dimension by Exponentiation" is commonly used in scientific research to ensure consistency and accuracy in measurements and calculations. It allows scientists to convert between different units and determine the dimensions of complex physical quantities, which is crucial in many fields such as physics, chemistry, and engineering.

3. Can you provide an example of "Dimension by Exponentiation"?

One example of "Dimension by Exponentiation" is in calculating the volume of a cube. The volume of a cube is determined by taking the length of one side and raising it to the third power, or cubing it. This is expressed as V = l^3, where V represents volume and l represents the length of one side.

4. How does "Dimension by Exponentiation" relate to the concept of units?

"Dimension by Exponentiation" is closely related to units, as it is used to determine the dimensions of physical quantities. Units are used to measure and represent these quantities, and by using "Dimension by Exponentiation," scientists can ensure that their calculations and measurements are consistent and accurate.

5. Is "Dimension by Exponentiation" used in all branches of science?

Yes, "Dimension by Exponentiation" is a fundamental concept that is used in all branches of science. It is especially important in fields such as physics, chemistry, and engineering, where precise measurements and calculations are crucial for understanding the physical world.
