the point is that a cell in standardform is not what it seems, its actually a cell in a different format from that which it appeared in, but the user is in control of the format via the showdefinitions item. in my humble opinion the best way to use mathematica in an apl environment is to forget about standardform and format cells as you type them. then you can apply the n[..] and input[.] operators without reformatting the cell to standardform.
anyway, the final line above, if you recall, has the effect of playing the note of g on the g string of the midi keyboard. this isnt a trivial function, since it has to simulate the midi keyboard, but it is a very neat piece of code. its also a nice illustration of the underlying strategy of mathematica. instead of adding the code line by line, the designers wrote the whole thing in a clever and efficient way, so that the addition is implicit, and just the original expression is evaluated.
the two big changes in version 5.2 have been to the notebook interface and to the internet. the five year old old apl interface, present since version 4.0 and referred to as the “old interface” has been replaced by the “new interface”. the old interface is very much a work in progress and will be gradually replaced by the new interface in future versions of mathematica. but it has served its purpose and is a good introduction to mathematica. the new interface will be the default in versions 5.3 and above.
the other big change is to mathematica’s internet connectivity. in version 5.2 it can no longer be assumed that if you have an internet connection then mathematica will be able to use that connection. (i tested this in the uk, india and the us, all with the same result). instead mathematica tries to find a suitable local network. in these circumstances it can use the local network, or it can connect directly to the internet. in the latter case it tries to use the connection first to a server maintained by wolfram research for e-mail, a server, in fact. if this fails, it tries to establish a connection directly to mathematica’s home page. if neither server nor direct connection is successful, it will give up and connect to the server at wolfram.com, the home of mathematica.
I should also mention that there is little that is new in Mathematica. The M-code and the full-scale powers of the proprietary Package Manager and the Solver are essentially a push-button version of available software. It is the new level of functionality for such tools that is the real trick, in my book.
Perhaps the most important lesson of all for Mathematica users is to concentrate on the thing you want to do, to ask questions, to explore, to play. Mathematica is a tool for doing things and is not a suite of applications, though it is capable of replacing many packages in the Mathematica system. As a metaphor, it has many of the functions of a compound microscope. If you want to see detail, you dont start with an eyepiece at the very edge of your visual field, you look at things through the lens.
If you want to solve a problem, its an essential starting point to ask the question first. That question, to me, is of paramount importance. What we want to know can be phrased as a mathematical (or if need be numeric) formula. I found, in the course of my own PhD, that I could arrive at my own formulation of the problem a great deal faster than by beginning by reading on for answers. So I began the process from the formulation. And to answer that question, one must tackle the component parts of the problem: meaning the words, clauses, symbols, operators, definitions, distributions, functions, sequences and names. The relative ease with which these can be processed, combined or manipulated, will determine the time available to the person solving the problem. So they must be developed and built. It is only through this process that they may be resolved.
