An algorithm can produce an infinite string of symbols from a finite amount of information (e.g. PRINT SQRT(2)), but a sequence containing an infinite amount of information can’t exist in reality..”

“..information is change in entropy, and entropy is the sum or integral of p log p. The informal definition is a summary of what dictionaries say. For example. The American Heritage Dictionary 4th edition gives 7 definitions, which are knowledge, facts, data, numerical measures of uncertainty, and a legal definition (“a formal accusation of a crime”).
