I wonder if the post with a semi circle opening in phi spiral fashion, is the symbol which invokes an intuitional understanding of phi?
What does the post represent, 3rd dimensional reality?

Hi! Just adding a few points:
1) In mathematics, it is common practice to write variables in italics, and thus to have a slanted φ (or ϕ), although nowhere as slanted as an ø.
2) The stroked O (Ø) is NOT an ASCII character. It is however available in both the ISO-8859-1 and Windows-1252 character sets, at positions 216 (upper case) and 248 (lower case).
3) Phi (Φ) is not available in those character sets, and thus cannot be input on old Windows systems based on Windows-1252. It was, however, available in the old code page 437 of the original IBM-PC, at positions 232 (upper case) and 237 (lower case). The Alt trick is a compatibility feature designed to access characters by their code point in this legacy code page. Ah, BTW, 1000 = 232 (mod 256), that’s why Alt-1000 works like Alt-232.
4) Modern operating systems are based on Unicode, and have thus many thousands of characters available, and means to input them, if not the fonts to display them. On Windows: Alt-0+decimal-code, on Ubuntu: Ctrl-Shift-U + hex-code + space.
5) The Unicode code points for phi (dec/hex) are: Φ: 934/3A6, φ: 966/3C6, ϕ: 981/3D5.
6) The Symbol font is a dirty pre-Unicode kludge where (semantically) Latin characters are given the APPEARANCE of Greek (or other) characters. You don’t need Alt codes with it, just type the letters ‘f’, ‘F’ or ‘j’ and you will get… an ‘f’, ‘F’ or ‘j’, but they will LOOK like ‘Φ’, ‘φ’ or ‘ϕ’ respectively. To someone who doesn’t have this font (I don’t), they still look like what they are, i.e. ‘f’, ‘F’ or ‘j’. There is no valid reason to use this kludge now that we have a Unicode-based Web.
7) The Wikipedia page on phi (section computing) has more detailed information on the different characters and glyphs that can represent phi.

Just in case if anyone needs it, ASCII code for Phi/phi

Φ – &# 934; – Greek capital Phi
φ – &# 966; – Greek lower case phi

Ø I used this symbol for the Greek letter Phi with the diagonal line through the O well over 50 years ago (Nearly 60 as a matter of fact). The first time that I recall using this letter was for the symbol for phenolphthalein (ØØ) which was an indicator solution………and I think that that was a couple of years before we started using computers……….as far as I can recall.
