We used to debate in engrg school about the ambient temp effect on the two different materials.
In my junior year(1975), my fiancee buys me a Texas Instrument calculator. Hottest thing on the market—$157.00.
That was a week’s pay for her at the time.
Made her take it back for a refund, I got better results with the slipstick.
Guys who used the calculators had no sense of the numbers and wrote down whatever the screen said was the answer.
If you did not know what you were doing, the calculator did not help you at all.
BTW, I married that girl. Wed 38 years this coming August.
