I really do believe that I /should/ be able to get this, but the texts
and so on that I have read make me feel like I am brain-damaged. /The
Little Schemer/ for instance is virtually line-noise from the very
first page.
This is something I know nothign about either, and it would certainly
help _me_ if somebody could explain what lambda calculus and 'closures'
are useful for.
To me all such things are tools for solving particular types of problems,
and knowing what those problems are is (at least to me) helpful, rather
than startign with a formal defintion and/or an example. For example, the
differential calculus (you know, dy/dx and all that) can be formally
definied in terms od limits, but there's also the intuitive idea that
it's to do with the rate of change of one quatity with repsect to
another. Thaat intuitive idea is very helpful at the start.
Or to put it another way. Would tuo ratehr undersntat what an
oscilloscope does by being given the scheamtic of one, or by being told
that bsaisclaly it dispalyes a grpahof hte voltage on the input socket
agianst time, and is therefore useful for exampling AC voltages and other
changing signals?
