AI Thread Summary
The discussion focuses on proving that all fractions between 1/2 and 1 can be generated starting from the fraction 1/1 using two specific rules. The first rule allows the transformation of a fraction a/b in lowest terms to b/2a, while the second rule permits the combination of two fractions a/b and c/d in lowest terms to create (a+c)/(b+d). By applying these rules iteratively, one can derive all fractions within the specified range. The thread also notes its similarity to an existing discussion on the same topic, leading to its closure. The proof demonstrates the versatility of fraction manipulation through these defined operations.

Suppose you begin with the fraction 1/1. There are 2 rules: a)If you can make a fraction a/b where a/b is in its lowest terms, then you can also make b/2a. b)If you can make a/b and c/d where they are both in lowest terms, you can also make (a+c)/(b+d).

Prove that you can make all fractions between and including 1/2 and 1.

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
