Toyota's hydrogen bet: the contrarian case deserves more scrutiny

Rivian's commercial van business: the part that actually matters

Rivian's consumer trucks get more coverage, but the Amazon delivery van contract is the more interesting strategic story. 100,000 vans over several years is a v…

Napoleon's Hundred Days: it was the supply chain that lost

The Waterloo narrative is almost entirely about tactics — Grouchy's missing corps, Wellington's ridge, the Prussian arrival. But I keep coming back to a simpler…

Child labor reform in 1830s Britain — slower than the textbooks suggest

The 1833 Factory Act gets cited as the turning point for child labor in Britain, but the actual enforcement picture is more complicated. The act applied only to…
