1912年双子座新星与引力透镜概念的起源
Nova Geminorum 1912 and the Origin of the Idea of Gravitational Lensing
摘要：
爱因斯坦的早期计算引力透镜，包含在一个草稿笔记本和日期为1912年春天，重新审查。爱因斯坦的一封迄今不为人知的信表明，他在1915年秋天接受了用引力透镜解释新星现象的想法，比以前假设的要认真得多。对爱因斯坦的相关计算的重新检查表明，确实，至少其中一些最有可能追溯到1915年10月初。但为了支持早期对爱因斯坦笔记的历史解释，有人认为1912年3月双子座新星1912（DN Gem）的出现实际上可能为爱因斯坦在1912年4月访问柏林期间与欧文·弗罗因德利希第一次会面时的透镜计算提供了相关的背景和动机。我们还评论的意义爱因斯坦的考虑引力透镜在1915年秋季重建爱因斯坦的最后一步在他的道路上向广义相对论。
英文摘要：
Einstein's early calculations of gravitational lensing, contained in a scratch notebook and dated to the spring of 1912, are reexamined. A hitherto unknown letter by Einstein suggests that he entertained the idea of explaining the phenomenon of new stars by gravitational lensing in the fall of 1915 much more seriously than was previously assumed. A reexamination of the relevant calculations by Einstein shows that, indeed, at least some of them most likely date from early October 1915. But in support of earlier historical interpretation of Einstein's notes, it is argued that the appearance of Nova Geminorum 1912 (DN Gem) in March 1912 may, in fact, provide a relevant context and motivation for Einstein's lensing calculations on the occasion of his first meeting with Erwin Freundlich during a visit in Berlin in April 1912. We also comment on the significance of Einstein's consideration of gravitational lensing in the fall of 1915 for the reconstruction of Einstein's final steps in his path towards general relativity.
