经典科幻文学:《生命 宇宙及一切》第7章1

Chapter 7
The Bistromatic Drive is a wonderful new method of crossing vast interstellar distances without all that dangerous mucking about with Improbability Factors.
Bistromathics itself is simply a revolutionary new way of understanding the behaviour of numbers. Just as Einstein observed that time was not an absolute but depended on the observer’s movement in space, and that space was not an absolute, but depended on the observer’s movement in time, so it is now realized that numbers are not absolute, but depend on the observer’s movement in restaurants.
The first non-absolute number is the number of people for whom the table is reserved. This will vary during the course of the first three telephone calls to the restaurant, and then bear no apparent relation to the number of people who actually turn up, or to the number of people who subsequently join them after the show/match/party/gig, or to the number of people who leave when they see who else has turned up.
The second non-absolute number is the given time of arrival, which is now known to be one of those most bizarre of mathematical concepts, a recipriversexcluson, a number whose existence can only be defined as being anything other than itself. In other words, the given time of arrival is the one moment of time at which it is impossible that any member of the party will arrive. Recipriversexclusons now play a vital part in many branches of maths, including statistics and accountancy and also form the basic equations used to engineer the Somebody Else’s Problem field.
The third and most mysterious piece of non-absoluteness of all lies in the relationship between the number of items on the bill, the cost of each item, the number of people at the table, and what they are each prepared to pay for. (The number of people who have actually brought any money is only a sub-phenomenon in this field.)
The baffling discrepancies which used to occur at this point remained uninvestigated for centuries simply because no one took them seriously. They were at the time put down to such things as politeness, rudeness, meanness, flashness, tiredness, emotionality, or the lateness of the hour, and completely forgotten about on the following morning. They were never tested under laboratory conditions, of course, because they never occurred in laboratories not in reputable laboratories at least.

第七章
意馆数学驱动，是一项全新的星际远距离穿越技术，它避免了非概率因数所带来的危险性。
意馆数学驱动是一种革命性的思维方式，即对于数字行为的全新理解方式。就好比爱因斯坦发现，时间不是绝对的，它决定于观察者的空间运动；空间不是绝对的，它决定于观察者的时间运动。同样地，人们现在认识到，数字不是绝对的，它决定于观察者在餐厅的运动。
第一个非绝对数字，是预留座位的人数。它会随着前三个订餐电话的内容而变化，而与实际到场的人数没什么联系，也与中途从演出/比赛/派对/特约音乐会过来的人数没什么联系，也与那些看到某个人来了而离开的人数没什么联系。
第二个非绝对数字，是约定的到达时间，如今已被公认为最古怪的数学概念之一。它是个互斥可逆数。这个数，其实只有在它作为别的数时才存在。换句话说，约定的到达时间，就是任何一位客人都不会在那时到达的时间。互斥可逆数如今在数学的多个分支学科发挥重要作用，包括统计学、会计学等，同时也为“别人的问题作用场”提供基本算法。
第三个、也是最神秘的非绝对性现象，存在于以下四者的相互关系之中：帐单上的条目数，每一条目的费用，餐桌上的人数，以及每人准备付的钱数（真正带了钱的人数，只是这个问题下面的一个亚现象）。
如此繁杂（而又时常发生）的大问题，却在多少个世纪里完全不为人知。这是因为，没人重视它。人们总是将其归结为礼貌、粗鲁、小气、炫耀、疲倦、激动或是迟到的结果，并在第二天早上彻底忘了这件事。他们从未在实验室条件下测试过，当然，这些问题从不在实验室发生——至少不会在声誉良好的实验室发生。
