“关于近世最伟大的头脑如何改变我们看待世界方式的经典记述，现已更新，为纪念其首批突破性思想诞生百年的 Einstein Year 增补了新后记。”“Albert Einstein 构建的宇宙是一幅由弯曲星光、高速飞行的宇航员、黑洞、风暴肆虐的星系和爆发时空组成的惊人苍穹图景。今天，我们比以往任何时候都更确信自己生活在他所描绘的宇宙之中——然而我们往往仍无法理解它。Nigel Calder 的这部里程碑式著作因让爱因斯坦的 theories of relativity 变得通俗易……”

…即使类星体远在数十亿光年之外你也能看到它们（辐射会加热周围的物质，使其非常明亮）。除了通俗物理读物外，我推荐读读《Einstein's Universe》这本书，有助于建立对狭义和广义相对论的总体认知，尤其是关于质能等价这类问题的理解。
…you can see quasars even though they are billions of light-years away (the radiation heats the surrounding material and it is very bright.) Besides general physics reading, I can recommend the book "Einstein's Universe" to help build a general understanding of both special and general relativity, with particular regard to matters such as mass-energy equivalence.
…从地球上看过去正好是侧面正对着我们，所以我用大写字母 O 表示木星，卫星用小写字母表示。我用热敏打印机（就像打那种宽收据）把它打了出来。当时电视上《Cosmos》正火，我也读过 Nigel Calder 写的《Einstein's Universe》。我有一台望远镜和一台显微镜，所以微观和宏观世界对我来说都特别真切。我怀疑如果你从小玩平板长大、只在 3D 打印机尺度上捣鼓过东西，可能就很难体会到那种无拘无束的…
…edge-on to our view from earth, so I made Jupiter a capital O, and the moons were lowercase letters. I printed this out on a thermal printer (like a wide receipt). Cosmos was the rage on TV and I had read Einstein's Universe by Nigel Calder. I had a telescope and a microscope, so the micro and macro were very real to me. I suspect if you grew up on tablets and only built things on a 3D printer scale, you don't have that unbridled…
