:: algebra student asking herself: what's next for me? ::
I suppose you could say this minor semantic innovation or marketing wrinkle is about leveling the playing field.
In calling differential calculus "delta calculus" in contrast to the already-named "lambda calculus" we're giving the public an easy mnemonic, a hook into the sometimes obscure Math Wars.
The first battle, which the computer science camp won, was to get more computer-related content recognized as credit-worthy along the math track.
The second battle, coming up, is to introduce a fork around algebra, such that going forward students have, in broad outline, these two tracks: lambda and delta.
Currently, "delta calc" is the road hog du jour, with "lambda calc" the competing underdog, angling for more bandwidth / market share / attention.
The CS crowd needs to stay with its strong suit: graphics and visualizations. We get that with the network / polyhedron of nodes and edges, the stuff of graph theory and graph databases.
