为什么值得读
- 构想通过电脉冲模拟触感的动态物体技术细节
- 书中五格骨牌的情节引发读者持久的编程探索
- 勾勒太阳系已被殖民的宏大未来社会图景
Duncan Makenzie 是土卫六 Titan“第一家族”的最新一代成员，Titan 是一颗已成为人类殖民地的土星卫星。早在23世纪初由他的祖父 Malcolm Makenzie 建立定居点起，Titan 的经济便依靠开采并销售大气中的氢气而蓬勃发展，这些氢气被用作行星际宇宙飞船聚变引擎的燃料。故事开始于2276年，诸多因素交织在一起，使得对“母星”地球进行一次外交访问成为必然。首先是即将到来的美国独立500周年庆典，正吸引着来自整个星系

……既涨知识又发人深省。这个就纯粹是怨气冲天的吐槽，没有任何干货。说到数字化表面，我觉得阿瑟·C·克拉克在《地球帝国》（Imperial Earth）里描述的那种能改变表面触感的物体简直绝了。它的“工作原理”本质上是通过向皮肤传输电脉冲来模拟触觉——物体本身并没有变化。不知道现在有没有这方面的研究。
…informative and inspiring. This just feels like a grumpy rant, and it adds nothing. On the matter of digital surfaces, I found the description of an object which changed surfaces in Arthur C. Clarke's Imperial Earth fascinating. It essentially "worked" by transmitting electric pulses through the skin that simulated the feelings - the actual object didn't change. I wonder if there's research in that area.
……我 46 年前刚读到这篇时，我有一台 Apple II+。于是我针对 Apple 在机器码和 Basic 上做了一些调整，成功跑了起来。那篇文章（连同阿瑟·C·克拉克的《地球帝国》）开启了我对五格骨牌（Pentominoes）一直持续到今天的痴迷。我把那段代码拿出来，用 Fortran、Pascal、C、C++ 和 Python 都重写并改进过。当年我把那篇文章复印下来，带在身边好多年……
…originally read this, 46 years ago, I had an Apple II+. So I made some adjustments to the code for the Apple in both the machine code and basic and got it working. That article (along with Arthur C. Clarke's Imperial Earth) started my obsession for Pentominoes that exists today. I've taken that code and rewritten and improved it in Fortran, Pascal, C, C++, and Python. I'd copied that article and carried it with me for years…
……对现代科技演进与认知所做的贡献。从通信卫星（地球同步轨道被称为“克拉克轨道”就是因他得名），到加密智能手机（在《地球帝国》中有生动的描写），再到太空电梯（《天堂的喷泉》）——他提出了如此多如今看来稀松平常的概念。（我还记得高中时因为提出这种离谱的……
…contributions to the evolution and perception of modern technology. From communications satellites (the geosynchronous 'Clarke orbit' is named after him) to encrypted smartphones (described vividly in Imperial Earth), to space elevators (The Fountains of Paradise) - he introduced so many ideas that are now regarded as unremarkable. (I remember being attacked and ridiculed in high school when I brought up the preposterous…
……恶心套路（出厂自带间谍软件、联想、反人类的奇葩工效学设计（苹果键盘、Touch Bar）），再加上 BDSM 级别的 Bootloader 限制（Android），简直让我生理不适。我之前还在回味，阿瑟·C·克拉克早在 1976 年的《地球帝国》里，就凭借他的 minisec 差不多预言了智能手机，虽然有一些扎眼的差别。比如它有实体键盘（书中提到‘E’键磨损了），设备坚固耐用……
…games (factory-installed spyware, Lenovo, craptacular ergonomics (Apple keyboards, strips), and BDSM bootloaders (Android) leave me feeling physically ill. I was reminiscing earlier that in his 1976 book Imperial Earth, Arthur C. Clarke more-or-less pressages the smartphone, with his minisec, though with some glaring distinctions. There's a physical keyboard (the 'E' key is mentioned as being worn), devices are durable…
……在很大程度上——通常受限于热学、摩擦、振动、应力或其他极限。有人曾提议过“垃圾填埋场采矿”。这在阿瑟·C·克拉克 1976 年的《地球帝国》里是一个要素（不过是 minor 意义上的，而不是 miner 矿工的双关）。从历史上到现在，这也一直是人们的实际做法，并带来了一系列的后果。这里更普遍的问题在于，回收利用的效率充其量也达不到 100%，而且随着一代代的……
…to a considerable extent -- generally to thermal, friction, vibrational, stress, or other limits. Landfill mining has been suggested. It was a (minor, though not miner) element in Arthur C. Clarke's Imperial Earth* (1976). And has long been practiced, historically and presently, with a range of consequences. The more general problem here is that recycling is at best less than 100% efficient, and the generational…
……纯推测性的论文。我还没看小说摘录，但我猜其设想应该是把物质一点点喂进微型黑洞里来维持它。（阿瑟·C·克拉克大概 40 年前就在他的《地球帝国》小说里提出了相同的概念。）我猜你想表达的是，1 个 GeV 能量微不足道，根本不可能推动 130 千吨的东西以任何速度行进。
…speculative paper. I haven't read the story extract, but I assume the plan would be to bleed matter into the micro black hole to maintain it. (Arthur C Clarke posited the same concept 40 odd years ago in his Imperial Earth novels.) I assume your point is that a GeV is a minuscule amount of energy, which isn't going to push 130kT around at any speed.
