AI Thread Summary
The discussion focuses on fitting squares into a 16.5cm x 14cm rectangle, with size constraints of 0.5cm to 2.5cm. After converting the dimensions to millimeters, the prime factorization reveals that the only common factor is 5. This means that the only size of squares that can perfectly tile the rectangle is 5mm x 5mm, or 0.5cm x 0.5cm. Larger squares, up to 2.5cm, cannot fit without leaving gaps. Thus, complete tessellation is only achievable with the smallest square size.

Hi, I'm a product designer looking for some help.

I need to fit squares into the dimensions of a rectangle. There can be any amount of squares just as long as the squares are complete and their dimensions are complete decimals.

The dimensions are 16.5cm x 14cm. I don't want the squares to be any larger than 2.5cm or any smaller than 0.5cm.

I would convert the dimensions of the rectangle to mm, so that you have 165 mm X 140 mm. Next, let's look at the prime factorization of both measures:

$$140=2^2\cdot5\cdot7$$

$$165=3\cdot5\cdot11$$

We see that the only common factor is 5, so your only choice (for complete tessellation) is to tile the rectangle with squares 5 mm X 5 mm, or 0.5 cm X 0.5 cm.
 
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...
