Rupert Representations
Posted:This post is a collection of symbols for myself. It's exactly as self-centered as it sounds.
# Pronounciation
Using IPA my name is pronounced: rʉ́wpət məˈkaɪ
# Images
Here's a headshot of me. It was taken some time around 2018 or 2019.
And here's another which has been roughly cropped. I upload this as a custom emoji everywhere I can 😄
# Morse
The following glyph is a representation of "RM" using Morse code. I use it in a couple places as a little visual break throughout this website.
█ ███ █ ███ ███
The first row is the letter "R" and the second row is letter "M". Not all letters of the Morse alphabet are symmetric or of equal length, so it was especially lucky how "RM" lined up so neatly like this. I would have preferred to use "RFM" but the letter "F" is not symmetric, nor of equal length to the others. If I included the "F" then the "RFM" glyph would look like this.

# Braille
I'm as fond of Braille as I am of Morse code, and yet I haven't found any way to render my name that looks particularly interesting with it.
Here for example is "rfm":
⠗⠋⠍
Or "Rupert Foggo McKay":
⠠⠗⠥⠏⠑⠗⠞⠀⠠⠋⠕⠛⠛⠕⠀⠠⠍⠉⠠⠅⠁⠽
There's a nice little encoder for Braille at cable.ayra.ch/braille. Or you might like to try learning braille yourself at learn-braille.
# Schläfli Symbols
The numbers of letters in each part of my name are as follows:
- "Rupert" has length 6
- "Foggo" has length 5
- "McKay" has length 5
We can use these numbers in Schläfli symbols to generate various polytopes.
-
{6/5}={6/1}={6}is just a hexagon 😄. -
6{5}is six interleaved pentagons, forming a Compound polytope. It looks like this:
{6,5}is an infinite tiling of hexagons, with five arranged around each vertex. This is not possible in Euclidean 2D space, but is possible on a hyperbolic plane. Order-5 Hexagonal Tiling. It looks like this:
{6,5,5}is hard to explain. By construction: take five copies of the previous polytope ({6,5}) and arrange them around a common point. But since the previous polytope was already an infinite tiling of a hyperbolic plane, the result for this one is a hyperbolic honeycomb. It looks like this:
