Very cool, thanks for sharing. I would note, that one nice thing about embedded mode is that there is no need for the #+begin/end_src calc blocks, rather the formulas may be placed directly in the Org-mode file. So to re-write a small portion of your previous example...
#+Title: Emacs Calc Embedded Mode Examples * Temperature Conversion (solving equations) Conversion from Celsius to Fahrenheit involves multiplication by 1.8 and the addition of 32 as shown below. eq := f = 1.8 c + 32 Solving for Celsius from Fahrenheit is then. ceq := solve(eq, c) => So, if we know that water boils at 100\deg Celsius, we can find the boiling point of water in Fahrenheit. subst(eq, c, 100) => Or if we know that paper burns at 451\deg Fahrenheit, we can find the burning point of paper in Celsius. subst(ceq, f, 451) =>
Using embedded mode is still fairly awkward for me. I would benefit greatly from some sort of quick reference card explaining the key bindings and maybe an easier way to switch to/from embedded mode. > and there are funny results with spaces in names.

I've long felt that calc would be a *very* powerful tool, if only I could climb the learning curve. Thanks, -- Eric Schulte http://cs.unm.edu/~eschulte
