" V. Calculations in plutonium chemistry
Short algorithms for plutonium chemistry problems
… a number of books on optimization have appeared … while some of them describe the sequential simplex algorithm, none of them makes the observation that this algorithm can be shortened to the point that it becomes a powerful tool for computing equipment as simple as the programmable pocket calculator …
… Listed in Tables V-1 and V-2, respectively, are two- and three-variable minimization routines abbreviated as described above. These routines may be used to solve a variety of chemistry problems by the method of proportional equations [5]. The routines are suitable for the HP-67 or HP-97 calculators manufactured by the Hewlett Packard Company …

How powerful is this ancient calculation tool, to think that the great discoveries of the brilliant researchers were made with pencil and paper, or at most a slide rule; I am referring to Dimitri Mendeleyev, Marie Curie, Antoine Lavoisier and John Dalton among many others. Thank you as always for your valuable contributions to the HP 67/97 library. Pedro
