1965年12月4日《自然》补充961，这件事发生了，但这并不是决定性的。从1621年他母亲最终被判无罪到他去世的十年间，开普勒在准备这一时期的主要著作时，抽出时间用几倍于《梦》原文的脚注对《梦》的原文进行了润色，这些脚注对叙述进行了文学和科学上的解释，这些解释已被痛苦的经验证明是必要的。《梦》的大部分科学部分是清醒的探索从月球上观测到的天文现象是由于月球的轨道运动，一面永远朝向地球;这一部分在今天是完全可以接受的，除了太阳的距离被低估了六倍之外。然而，开普勒也相信月球上有空气、水和居住在洞穴中的居民，他们可以躲避极端的高温和寒冷;笔记中关于这些主题的论点，以及月球之旅的预防措施，对他的物理知识提出了有趣的侧面。约翰·李尔在委托这一优秀的翻译和提供一个迷人的介绍，其中指出了这一被遗忘的工作的重要性和1609年手稿的误解的有害影响是重建的基础上，在1634年版的tho第一次有用的服务。我唯一的批评是，李尔王似乎混淆了海里和法定英里的一段话，因此，他认为开普勒对月球距离的估计比他实际拥有的要不准确。伯纳德·帕格尔
Supplement to NATURE of December 4, 1965 961 that this happened is not conclusive. During the decade between his mother's eventual acquittal in 1621 and his own death, Kepler took time off from the preparation of his major works of this period to embellish the original text of the Dream with several times its own length of footnotes giving those literary and scientific explanations of the narrative that had been proved necessary by bitter experience.Most of the scientific part of the Dream is a sober exploration of the astronomical phenomena observable from the Moon as a result of its orbital motion with one face permanently turned towards the Earth; this part would be entirely acceptable to-day apart from the fact that the Sun's distance is underestimated by a factor of six. However, Kepler also believed that the Moon had air, water and inhabitants who sheltered from the extremes of heat and cold in caves; the arguments on these subjects in the notes, and the precautions suggested for the journey to the Moon, throw an interesting sidelight on his improssive physical knowledge. John Lear has performed a useful service in commissioning this excellent translation and in providing a fascinating introduction in which the importance of this forgotten work is pointed out and the baleful effects of the misinterpretation of the 1609 manuscript are reconstructed for the first time on the basis of tho notes in the 1634 edition. My only criticism refers to one passage where Lear seems to have confused nautical miles with statute miles and consequent, ly credits Kepler with a less accurate estimate of the Moon's distance than ho actually possessed.
