Entropy (information theory)
Shannon’s 1948 theory redefined communication as a mathematical problem of uncertainty reduction. He proved entropy is the irreducible cost of lossless encoding — not a metaphor, not a heuristic, but a bound. It applies only where messages are statistically structured, and only to syntactic information — never semantics. Its power lies in its narrowness.

Google is a search engine company founded in 1998 by Larry Page and Sergey Brin. Its core technology, PageRank, ranked websites by inbound links — a method co-published with Motwani and Winograd and patented by Stanford. Scott Hassan wrote the first implementation. The company launched from Susan Wojcicki’s garage. Its name misspelled 'googol' to signal scale. Initial funding came from Andy Bechtolsheim’s $100,000 cheque in August 1998. The sources say nothing about advertising, revenue, users, infrastructure costs, or market position beyond this.

International Bank Account Number
IBAN is a validation layer—not a payment rail, not a registry, not a protocol. It catches human input errors in account identifiers before they trigger costly rejections downstream. Its mechanism is simple: a fixed-position country code, two check digits, and a national account identifier, all validated via MOD-97-10. It works where people type numbers. It fails where logic, intent, or authority is required.

ASCII
ASCII is a cost-driven, committee-built encoding that prioritised transmission efficiency and hardware simplicity over linguistic coverage. Its rigid separation of control and graphic codes enabled early parsing — but its 28 reserved slots and lack of international support created immediate pressure for extension.

ISBN
The ISBN is a pragmatic, nationally administered, error-checked identifier for book editions. It succeeded because it solved a narrow operational problem—inventory control—with minimal abstraction. It does not describe content, authorship, or meaning. Its longevity comes from institutional adoption, not technical elegance.
