Lord of the Rings vs. Discworld: Two Cosmologies for the Tech Age

This essay contrasts the worldviews presented in *The Lord of the Rings* and Terry Pratchett's *Discworld* series. It argues that *Lord of the Rings*, while a great story, offers a simplistic, deterministic view of technology and society unsuitable for a technologically advanced species. In contrast, *Discworld*, with its ironic and absurdist approach, provides a far superior model for understanding technological progress, societal evolution, and human interaction with these forces. The author advocates for embracing the pluralistic and generative worldview offered by *Discworld* over the limiting, Chosen One narratives of *Lord of the Rings*.

Formal Specifications: Beyond Instructions, Defining Software Behaviors

This post delves into the distinction between formal specifications and traditional programs. While programs are lists of instructions, formal specifications are sets of behaviors. Using a counter example, the author illustrates how specifications define all correct behaviors and leverage set theory, employing generators (Init and Next) to describe infinite sets of behaviors. This contrasts with the concept of nondeterminism in programming; in formal specifications, nondeterminism refers to multiple ways a behavior can be extended, while in programs, it refers to uncertain code paths. The article emphasizes understanding formal specifications as sets of behaviors, crucial for debugging and interpreting model checker errors.

Zipf's Law in Whale Song: A Striking Similarity in Cultural Learning

Zipf's Law in Whale Song: A Striking Similarity in Cultural Learning

New research reveals that humpback whale songs exhibit the same Zipfian distribution found in human languages—the most frequent word is twice as frequent as the second, and so on. Researchers analyzed eight years of whale song recordings, using techniques inspired by how human infants learn language, to uncover this pattern. This suggests both human language and whale song possess statistically coherent parts, following Zipf's law, likely because cultural learning makes learning easier and promotes the emergence of these properties. However, this doesn't mean we can talk to whales; the meaning of whale song remains unknown. Future research will explore other species, such as songbirds, to test whether cultural learning is the common driver of this phenomenon.
