Look, do you really want me to wade through sixteen pages to discover the notation first (written by someone who doesn't know about \langle and \rangle, either)? I would consider it bad argumentative form of the same water as Euler's apocryphal "does God exist" debate with Diderot. At the very least, you will struggle to persuade me that the use of \wedge is easier to understand than the English word "and" with line…

>do you really want me to wade .... No - just pointing out that no matter how hard you studied that an English equivalent of such a terse expression will be a mess, vastly harder to understand. >At the very least, you will struggle to persuade me that the use of \wedge is easier to understand than the English word "and" with line breaks. You're making my case for me :) The word "and" and "or" are ambiguous in common…

> No sense in continuing.

On this we agree, at least!

Clearly you are too much of a pedant to do anything useful in life, so why don't you build a time machine and interrupt your birthing process ? It should be easy ... you can build it using calculus.

Science is about modelling the real world. Mathematics is about modelling. Programming is "interactive" modelling. Its all about modelling accurately.

Clearly you are also too much of a bigot to understand that models are just models and unreadable and undecipherable models are useless and full of shit, especially those built by schizophrenics or priests.

> If you say no, then I challenge you to construct a useful and consistent version of calculus without formal mathematics.

That was how it was constructed in the first place genius. Both calculus and fourier were built for practical purposes before formalist clowns were even alive probably. So why don't you go read the originals.

Formal calculus is beyond useless, its unreadable.

Not true at all, there are several times I've attempted to read through a textbook only to be stopped by notation because something was introduced prior to being referenced, or notation is overloaded with multiple meanings. I consistently have run into "perceived or real" confusing mathematical notation as an impediment to learning in a way that programming languages have never, ever caused me. Does no one else feel…

You are making the huge mistake of assuming that if you hadn't given up when facing difficulty with the notation, the rest would have been easy, that you would have no trouble understanding the concepts! Don't worry: you are not alone in making that huge mistake, plenty of people do. People that don't give up when confused about notation usually quickly learn that is the concepts and relations between them that requi…

You are in no position to assume rytill 'gives up when confused about notation'.

Difficulties, if any, perceived or real, arising in connection with notation, are usually incomparably smaller than those presented with the subject itself. (Personally, I only wish mathematical notation were better integrated with software in general and programming languages in particular.)

The C pointer syntax can be confusing even to experienced C programmers.

I thought that was what he or she meant by "there are several times I've attempted to read through a textbook only to be stopped by notation". I wouldn't have said what I said otherwise.

To me it seems language can also be interpreted as more ambiguous, where as well defined symbols and notation are far more rigorous in definition and use.

Except you have instances of misuse of those well-defined symbols and notations. Without any accompanying language it can be very difficult to not only determine that there is an error, but then also figure out how to fix it. And other times in some fields there is a lack of well-defined symbols and notations. I don't recall the specifics, but in game theory there is some notation that is ambiguous. There are two met…

my main argument is that humans only have so much sort term memory so compression is crucial for readability. Reading a proof is different than reading a book because you have to retain the whole thing with details in your mind not just vague ideas.

I find myself completely unable to understand that. I suspect we use very different methods. Notation doesn't stay with me once my eyes move past it. The notation is merely there to inform me of what is happening, and as long as I understand the meaning it doesn't matter if it was one symbol or a whole paragraph.
