Hacker News 上怎么说

  • 我觉得罗伯特·福沃德(Robert Forward)的作品都算得上。我最喜欢的是《罗氏星》(又名《蜻蜓号的飞跃》)——https://en.wikipedia.org/wiki/Rocheworld,以及《龙蛋》——https://en.wikipedia.org/wiki/Dragon%27s_Egg

    I think all of Robert Forward's stuff would qualify. My favorites are Rocheworld (AKA The Flight of the Dragonfly) - https://en.wikipedia.org/wiki/Rocheworld and Dragon's Egg - https://en.wikipedia.org/wiki/Dragon%27s_Egg

  • 物理学家罗伯特·L·福沃德在20世纪80年代初的书《罗氏星世界》(后来重版书名为《蜻蜓号的飞行》)中提到过它,而概念研究在70年代就完成了。https://en.wikipedia.org/wiki/Solar_sail#Interstellar_flight

    Physicist Robert L. Forward mentioned it in his book Rocheworld (later republished as The Flight of the Dragonfly)in the early 1980's, with the concept work being done in the 1970s. https://en.wikipedia.org/wiki/Solar_sail#Interstellar_flight

  • 在采用相同推进系统的小说《蜻蜓号的飞跃》中,他们只是拆下了一部分帆面,用它将光束反射回航天器来进行减速。

    In the story "Flight of the Dragonfly", which used the same propulsion system, they simply detached a portion of the sail, and used it to reflect the beam back at the spacecraft to decelerate it.

  • 那就是《蜻蜓号的飞跃》了。不过从另一方面看,同一个书评人把小说里的外星人形容成了加州冲浪客……

    It was "The Flight of the Dragonfly". One the other hand the same reviewer described the aliens in the novel as being Californian surfers....

  • ……取决于未来的物理学发现(也许涉及虫洞?)。只要不与已知物理学产生明显矛盾就挺好。但真正硬核的做法是像罗伯特·福沃德在《蜻蜓号的飞跃》[1]里那样:里面包含了30多页和12张带有技术细节的图表。他完全是按照真实航天任务提案的水平把一切推演出来的。[1] https://en.wikipedia.org/wiki/Rocheworld

    …on future physics discoveries (maybe involving wormholes?). That's fine as long as there is no obvious contradiction of known physics. The really hard way though is to do what Robert Forward did in "Flight of the Dragonfly [1]: it includes 30+ pages and 12 figures with technical details. He worked it all out at the level of a real mission proposal. [1] https://en.wikipedia.org/wiki/Rocheworld
