2025-09-01

The 1856 caning of Senator Charles Sumner by Representative Preston Brooks is a notorious event highlighting the fractured political climate before the American Civil War. Less known is the story of the cane itself, crafted from gutta-percha, a natural rubber from Southeast Asia. This seemingly innocuous material proved crucial to the 19th-century communications revolution, enabling the transatlantic telegraph cable. However, the insatiable demand led to widespread deforestation and environmental devastation, ultimately replaced by synthetic plastics. The story serves as a cautionary tale about the unforeseen consequences of technological advancement and the need for sustainable practices.

2025-04-10

This article recounts the origin story of the modern museum, starting with the 17th-century craze among wealthy individuals for collecting curiosities in 'cabinets of curiosities'.

Molon Labe: The Modern Myth of Sparta and its Dangerous Interpretations

2025-02-19

This essay explores the modern American popularity of the Spartan motto "Molon Labe" ("Come and get them") and its complex cultural and political implications. From the movie *300* to gun culture, the phrase has become a symbol of defiance. However, the author argues that idealized interpretations of Sparta often overlook the darker aspects of its social system, such as slavery and hierarchy. Historically, Sparta has been misused by various political movements, including French Revolution radicals and the Nazis, to support their agendas. The author cautions that admiration for Sparta may reflect modern society's own biases and political leanings rather than an objective understanding of history.
