Heinlein trabalha onde a regra de slide é usada para calcular a navegação no espaço

12

Uma pergunta no Space.SE; É possível navegar em viagens espaciais sem computador? me fez procurar uma lista de obras em que a Heinlein dependia exclusivamente de uma regra de slide para calcular a navegação no espaço.

Eu criei os Os Rolling Stones mas estou à procura de um lista abrangente.

Rocket Ship Galileo fez referências ao uso de uma régua de cálculo - além de mencionar como a precisão limitada significava que você tinha que ter um piloto humano em vez de "cortar uma câmera". piloto automático para fazer o trabalho.

Eu acho que lembro Space Cadet também mostrando regras de slide em uso para pilotar - e estes são os únicos livros de Heinlein que eu me lembro de "dentro do cockpit" o suficiente para mostrar esse tipo de detalhe . O Space Suit Will Travel mostrou as regras de slide em várias cenas importantes, mas os personagens nunca as usaram de fato.

Em Destination Moon , pelo menos está implícito que uma regra de slide está sendo usada para calcular a trajetória necessária para chegar à lua. A parte relevante da história é:

“Huh? I wasted reaction mass, so we’re going too fast? That doesn’t make sense." Barnes hooked a foot into the legs of the stool to anchor himself, and did a rough run-through of the problem with slide rule and logarithm table. “Well, boil me in a bucket!" He added humbly, “Doc, I shouldn’t have asked to be skipper. I don’t know enough."

Corley’s worried features softened. “Don’t feel that way, Jim. Nobody knows enough — yet. God knows I’ve put in enough time on theory, but I went ahead and urged you to make the blunder."

“Doc, how important is this? The error is less than one percent. I’d guess that we would reach the Moon about an hour early.”

“And roughly you’d be wrong. Initial speed is critical, Jim; you know that!”

“How critical? When do we reach the Moon?”

Corley looked glumly at the pitiful tools he had with him—a twenty-inch log-log slide rule, seven place tables, a Nautical Almanac, and an office-type calculator which bore the relation to a “giant brain” that a firecracker does to an A-bomb. “I don’t know. I’ll have to put it up to Hastings.” He threw his pencil at the desk top; it bounced off and floated away. “The question is: do we get there at’all?”

Em Starman Jones, não há nenhum metion explícito de uma régua de cálculo sendo usada para astrogation, no entanto, há uma referência implícita a ela:

There was little to take. Groping in the dark he found the rucksack he used for hunting hikes and stuffed into it his other shirt and his socks. He added Uncle Chet’s circular astrogation slide rule and the piece of volcanic glass his uncle had brought back for him from the Moon. His citizen’s identification card, his toothbrush, and his father’s razor—not that he needed that very often—about completed the plunder.
