Now as we have computers, why don't we introduce a nice graphical and colourful notation that would make formulas much more understandable? And I mean revamp all of it - not just fancy writing. Tensor contraction for example are ideal candidates for visualisation. It would be much easier to do algebra in the head. Of course some clever hotkeys for typing in this notation would be needed, but at the same time a computer algebra system could check transformations.(adsbygoogle = window.adsbygoogle || []).push({});

One drawback is of course that one always need a computer, but they are everywhere.

I have some ideas for such a system.

Are some ideas out there already?
