Historical Counterfactual Analysis
If the transistor had been invented in 1920 instead of 1947, trace the likely technological, economic, and geopolitical implications through…
The Transistor at 1920: A Speculative History Methodological Note First This is a serious analytical exercise, not science fiction. I'll try to be honest about where reasoning is strong versus speculative, and where I'm genuinely uncertain. The goal is to trace mechanisms, not just assert outcomes.Read the full answer
If the Transistor Had Been Invented in 1920: A Counterfactual Trajectory to 1980 Preconditions and plausibility By 1920, Karl Braun's cathode ray tube (1897) and Greenleaf Pickard's silicon crystal detector (1906) had already demonstrated semiconductor properties. Quantum theory was nascent (Planck, Bohr).Read the full answer
