> But are mathematicians too embroiled in some misguided quest for Huffman coding? I think that yes, they are: for centuries, mathematics has been written by hand. It's much easier to write 'f' than 'force'. on a blackboard. Moreover, when writing on paper, with ink that you have to make or buy, with a pen that wears out as you write with it, it makes sense that early mathematicians would embrace a compressed notation. Scribes even did it, so it shouldn't surprise us that mathematicians would. The compression is based on domain knowledge, and this is only problematic for people who are not intimately familiar with the domain at hand. Physics is similar. Decoding the rocket equation is only possible when you know what m1 and m0 are, or ve, and many properties, constants, and even operations are symbolized with a single greek letter. (Gradients, for example) This is very powerful, because (as others have mentioned) it allows you to easily write more-complex things, and often times you (as a mathematician or physicist) prefer to think at a higher level of abstraction. It also makes it tremendously arcane for those of us who don't even know the names of the greek letters, let alone have a sound backing in that particular field of math or physics.
