This is what Cris said in answer to my note:

“Had to read your posts a few times and honestly, I still don’t really understand. However, I could glean all the criteria that we originally set out to capture and that’s a great thing. Plus, from a design point of view, this new option would look fantastic. So let me come up with something.”

]]>Please refer back to the heritage of Quaker consensus used by APL implementers, and the free-form voting rules used by the X3J10 committee. There is nothing sacred about majority rule; in fact it may be the enabler of all evil, being the majority party’s legal means to coerce their neighbors. ]]>

This is more or less the note I sent to Cris on the subject of logarithm:

Roger Hui, building on Greg Jaxon’s suggestion (or perhaps it was simultaneous genius) came up with a really good logo idea and a rationale that I hadn’t considered.

It is a circle with an asterisk inside. I though that if we exaggerated it a little and made it bigger, it would look less like a radial button and I’m curious to hear what you think.

I like this new idea best because one of the beautiful things about APL is that it was invented as a notation. As laypeople, we might call it “math”. It was later implemented on the computer, keeping pace with the unfolding of computer evolution and was the first interactive computer language meaning that the symbols were used for people to talk directly to the computer.

AND at the same time, the symbols used for conventional mathematics became more rationalized, in terms of the symbols mathematicians use to talk to each other. As these two things, creating interactive computers and systematizing mathematical symbols for people were unfolding simultaneously in history and sometimes by the same people, some APL symbols actually made it into the mainstream; as far as you can call mathematicians and physicists mainstream. No other programming language can make this claim.

Let me know what you think and how you are doing.

]]>I don’t put too much stock into the *meaning* of the APL symbol, as a lot of the audience will not (we hope) be APL fanatics. However, I do like using an APL symbol as that is one of the distinguishing characteristics of APL. What would your design team think of the symbol ⍟ (logarithm)?

• the film is kind of a log (record);

• it’s kind of a cute symbol;

• it denotes a function for which conventional mathematical notation does not have a good symbol (what’s used is ln or log or loga (with the a subscripted));

• it alludes to deep connections between the log, exponential (*), and the circle (○) functions (see http://www.jsoftware.com/jwiki/Essays/Euler's_Identity );

• it is a nice pun (the symbol looks like the end of a log).

]]>also, with the current Euro turmoil, keeping away from a Euro symbol is probably very smart.

Of the two offered, rotate is at least symetrical whereas I looked at the epsilon and wondered; ‘Why?’. But I still think lamp better 🙂
