The linguistics section was making steady, if less spectacular, progress toward cracking the language. Many of the world's most prominent experts were getting involved, some choosing to move to Houston, while others worked via remote data links. As the first phase of their assault, they amassed volumes of statistics on word and character distributions and matchings, and produced reams of tables and charts that looked as meaningless to everybody else as the language itself. After that it was largely a matter of intuition and guessing games played on computer display screens. Every now and again somebody spotted a more meaningful pattern, which led to a better guess, which led to a still more meaningful pattern—and so on. They produced lists of words in categories believed to correspond to nouns, adjectives, verbs, and adverbs, and later on added adjectival and adverbial phrases—fairly basic requirements for any advanced inflecting language. They began to develop a feel for the rules for deriving variants, such as plurals and verb tenses, from common roots, and for the conventions that governed the formation of word sequences. An appreciation of the rudiments of Lunarian grammar was emerging from all this, and the experts in Linguistics faced the future with optimism, suddenly confident that they were approaching the point where they would begin attempting to match the first English equivalents to selected samples.

The mathematics section, organized on lines similar to linguistics, was also finding things that were interesting. Part of the diary was made up of many pages of numeric and tabular material—suggesting, perhaps, a reference section of Useful Information. One of the pages was divided vertically, columns of numbers alternating with columns of words. A researcher noticed that one of the numbers, when converted to decimal, came out to 1836—the proton-electron mass ratio, a fundamental physical constant that would be the same anywhere in the Universe. It was suggested that the page might be a listing of equivalent Lunarian units of mass, similar to equivalence tables used for converting ounces to grams, grams to pounds . . . and so on. If so, they had stumbled on a complete record of the Lunarian system of measuring mass. The problem was that the whole supposition rested on the slender assumption that the figure 1836 did, in fact, denote the proton-electron mass ratio and was not merely a coincidental reference to something completely different. They needed a second source of information to check it against.
