What, exactly, does this have to do with fractals or fractal geometry? Melchoir 21:43, 28 October 2006 (UTC)

The theorem. Well, can you imagine the set F described there? Normally, it's a fractal. It could be made precise in the article. --Beaumont (@) 21:58, 28 October 2006 (UTC)
Not everything complicated is a fractal. Are there sources for the mathematics? What do they say? Melchoir 01:05, 29 October 2006 (UTC)
This is a classical theorem in the fractal geometry... See Falconer "Fractal Geometry" cited in the fractal article. I shall copy it here, so thanks for your question. BTW, the current definition of what "fractal" is was inserted there on the basis of this monograph and I guess this is (one of) the best source(s). --Beaumont (@) 08:06, 29 October 2006 (UTC)

I know it has been six years since the first comment here, but looking at the patent for the digital clock, it is clearly not a fractal design. A fractal geometry would probably be useful for making solid numbers, but the designers get away with a simpler design by using numbers built out of vertical stripes with gaps between them. 209.131.76.183 (talk) 20:00, 1 November 2012 (UTC)

## Merge with Sundial

Shouldn't this be merged with Sundial? 124.82.2.241 18:23, 31 October 2006 (UTC)

Why? This seems quite well separated topic (theoretical basis, technical means) and, eventually, might get expanded here.--Beaumont (@) 20:19, 31 October 2006 (UTC)
Also, a seperate page probably has better marketing potential. 153.2.246.31 23:14, 31 October 2006 (UTC)

## Problems with Math and Text?

One bit of math looks wrong to me, but I'm out of my field. Specifically, immediately under the "Theorem" subhead, where it says [0,pi) - this looks like mismatched brackets to me.

"Sockets of optical waveguides" doesn't mean much to me; is "sockets" correct here?

Peter Delmonte 00:49, 1 November 2006 (UTC)

[0,pi) means the set of numbers between 0 and pi, but the [ indicates that 0 is included in the set, but the ) indicates that pi is not (ie everything from 0 up to but not including pi). – AlbinoMonkey (Talk) 01:39, 1 November 2006 (UTC)

Dang! I knew that once! Thanks for the explanation. Peter Delmonte 04:29, 1 November 2006 (UTC)

## A 3D Printed digital sundial on Thingiverse

There is something to print on https://www.thingiverse.com/thing:1068443 . (although, I not sure it is useful to print the inside) -- Xofc (talk) 16:17, 16 December 2015 (UTC)
