B What would need to be possible to make a cube of circles?

AI Thread Summary
A cube of circles is conceptually challenging due to the dimensional differences between three-dimensional cubes and two-dimensional circles. In topology, a sphere can represent an infinite collection of circles, suggesting a theoretical equivalence to a cube. However, traditional geometry, which involves measuring angles and lengths, cannot reconcile the roundness of circles with the edginess of cubes. Historical attempts to explore this concept date back to around 3000-2000 BC. The discussion also mentions the 3D Fourier transform of a square wave as a potential mathematical exploration of this idea.

None that I can think of. A cube is a three-dimensional object, while circles are two-dimensional.

It is possible in topology where a sphere that can be considered as an infinite collection of circles is equivalent to a cube. Geometry means that we can measure angles and lengths. This makes it impossible to get something edgy out of something round.

Not that we haven't tried: (##\sim 3,000 - 2,000 \text{ BC}##)

Thread 'Non-orthogonal bases'

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...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

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...
