Mathematic notation is complex, operator calculus is horrible & the only people who can read your average maths book is those with a memory that can cross reference a name of a constant with a letter, HTML/pdf/Word/LATEX document standards. needs a mathematical standard that one can hover the mouse over an equation & it expands mathematical variables to there full name, also, if the equation was expanded as a tree ( i.e. no brackets ), on a full page rather than as compact as possible on a single line. One could display full names of mathematical variables otherwise impossible so one wouldn´t be wrecking their head trying to figure out what an equation is acually saying because you don´t have to remember 20 variables written down in that very terse mathematical doctorial thesis 3 pages ago, &, you can´t get your head around. This idea I name, an equation tree, see example below in bad ascii art. This equation on a line without variable names shortened to fit look like speed of light in a vacuum = ( speed of sound in air * 2 ) + speed of sound in water a complex physics equation would take several lines fully expanded. Maybe it's an idea to have the equation tree only to pop up if you can't understand the equation in terse notation. D.J.
