Genomics Reveals the Origin of Indo-European Languages: An Ancient Secret from the Lower Volga

A groundbreaking genomics study has unearthed the surprising origins of the Indo-European language family. Researchers discovered that an ancient population from the Caucasus Lower Volga region was the ultimate source of Indo-European languages, sharing close connections with later Yamnaya culture and Anatolian language speakers. The Yamnaya culture spread Indo-European languages across Europe and into the Indian subcontinent through population expansion, with their unique cultural traditions, like kurgan burials, also stemming from the Caucasus Lower Volga people. This research not only reshapes our understanding of Indo-European origins but also showcases the immense potential of ancient DNA technology in tracing human history and cultural diffusion.

Lost Nicknames and the Origins of Surnames

Many English surnames derive from patronyms, often nicknames. For example, "Jackson" comes from "Jack" (a nickname for John). This article explores numerous now-obscure nicknames and their resulting surnames, such as "Wat" (a nickname for Walter) yielding "Watts," "Watson," "Watkins"; "Gib" (a nickname for Gilbert) yielding "Gibbs," "Gibson"; and "Hob" (a nickname for Robert) yielding "Hobbs," "Hobson," "Hobkins." The author invites further examples and adds the nickname "Hick" (for Richard) and its derivatives, and speculates on "-mott" possibly indicating an in-law.

Why Haven't Airplanes Gotten Faster Since the 1960s?

2025-02-10
Why Haven't Airplanes Gotten Faster Since the 1960s?

While technology has advanced rapidly, commercial air travel speeds haven't significantly increased since the 1960s. The primary reason is fuel efficiency. Modern high-bypass turbofan engines, while more efficient, operate most efficiently at slower speeds. This leads aircraft manufacturers to design slower planes, which are also cheaper to build. Supersonic flight, like Concorde, existed but was limited by sonic booms. Future supersonic business jets offer hope, but their political feasibility is uncertain.

LLMs Explain Linear Programs: From Side Project to Microsoft Research

2025-02-10

Back in 2020, while working in Google's supply chain, the author developed a side project to help understand linear programs (LPs). When LPs become complex, understanding their results is challenging even for experts. The author's approach involved interactively modifying the model and diffing the results to explain model behavior, finding that adding semantic metadata simplified the process. Recently, Microsoft researchers published a paper using Large Language Models (LLMs) to translate natural language queries into structured queries, achieving a similar outcome. The author believes LLMs are a great fit for translating human ambiguity into structured queries, processed by a robust classical optimization system, with results summarized by the LLM. While the author's early work remained unpublished, he argues that understanding explanations of simpler systems is crucial for explaining more complex AI systems.
