The most beautiful description of data compression
The next time you need to explain data (de)compression to someone, you would do well to refer them to this passage from Roger Angell’s essay Box Scores:
“The box score, being modestly arcane, is a matter of intense indifference, if not irritation, to the non-fan. To the baseball-bitten, it is not only informative, pictorial, and gossipy but lovely in aesthetic structure. It represents happenstance and physical flight exactly translated into figures and history. Its totals—batters’ credit vs. pitchers’ debit—balance as exactly as those in an accountant’s ledger. And a box score is more than a capsule archive. It is a precisely etched miniature of the sport itself, for baseball, in spite of its grassy spaciousness and apparent unpredictability, is the most intensely and satisfyingly mathematical of all our outdoor sports. Every player in every game is subjected to a cold and ceaseless accounting; no ball is thrown and no base is gained without an instant responding judgment—ball or strike, hit or error, yea or nay—and an ensuing statistic. This encompassing neatness permits the baseball fan, aided by experience and memory, to extract from a box score the same joy, the same hallucinatory reality, that prickles the scalp of a musician when he glances at a page of his score of Don Giovanni and actually hears bassos and sopranos, woodwinds and violins.”
