RPN(HP-31) vs AN(TI-57)

[lrdheat]

Interesting discussion...I agree that being able to see a full equation allows the operator to verify that this was the intended math. On the other hand, an operator using RPN, I feel (from my own experience) is much more intimately involved with the math being done. It reminds me of a discussion going on in the meteorology forecasting community concerning looking at computer real time surface analysis vs hand drawn analysis. At the SPC (NOAA/NWS’s Storm Prediction Center), the forecasters are encouraged to preform hand analysis as it is felt that this involves the forecaster to a greater extent into a full awareness of the initial atmospheric state.
