Calculating History

Welcome

Welcome to this collection of papers I wrote on historical calculating machines and mathematical instruments. Most of them have appeared in Dutch in the "Mededelingen en Informatie voor Rekenlinialenverzamelaars" (MIR)<br>You might also be interested in original documents on calculating history or the Rechnerlexikon, a wikipedia for calculating devices, or the Oughtred Society. If you have any comments, please leave them in the form at the right.<br>Andries de Man

In some respects, slide rules played the role of today's smartphones, as demonstrated by this quote of Charles Kettering:<br>When I was research head of General Motors and wanted a problem solved, I'd place a table outside the meeting room with a sign: "Leave slide rules here." If I didn't do that, I'd find someone reaching for his slide rule. Then he'd be on his feet saying, "Boss, you can't do it."
