The Secret Engineering of the Pencil
A useful design rarely announces itself. It becomes background, and background is where good engineering hides. The Secret Engineering of the Pencil is a good example because it sits at the meeting point of materials, manufacturing, regulation, and daily habit. People interact with it quickly, often without vocabulary for the choices embedded in the design…. Read More
Why Door Handles Look the Way They Do
The easiest things to overlook are often the hardest things to design well. Familiarity disguises constraint. Why Door Handles Look the Way They Do is a good example because it sits at the meeting point of materials, manufacturing, regulation, and daily habit. People interact with it quickly, often without vocabulary for the choices embedded in… Read More

The Most Innocent Object in Your Home Might Be Watching You

Every single day, we move through a world built not of grand monuments or rare artifacts—but of ordinary objects. The unnoticed. The mundane. The invisible infrastructure of… Read More
The Ideas We Left Behind – But Still Use Every Day
Imagine you are in an old library on a rainy evening. The main aisles are full of famous names: Newton, Einstein, Darwin, Curie. Their books are bright, clean and frequently borrowed. But then you turn into a quiet corner, where dusty volumes rest on high shelves. The names on their spines are unfamiliar. The pages… Read More

Phlogiston: The Beautifully Wrong Theory of Fire
• Phlogiston (17th–18th c.) posited a fire‑like essence released in burning/roasting. • Collapsed under mass gain in calcination and oxygen’s discovery; replaced by oxidation. • Left durable assets: quantitative balances, gas studies, and a caution about metaphors that feel right. 🔥
Blameless Postmortems: Shipping that Learns
• Blameless postmortems shift focus from who failed to what the system allowed. • Roots in aviation and safety science (Reason, Dekker); tech popularized via Google SRE. • Value: faster recovery, better design, higher trust; risks: performative rituals without follow‑through. • Add action tracking, owner, due dates, and review loops.
Goodbye, Leaded Gas: A Public‑Health Turning Point
• Tetraethyllead (TEL) added in 1920s to stop engine knock; mass neurotoxin. • Catalytic converters (1970s) and regulation drove phase‑outs; U.S. ban for on‑road gas by 1996; global near‑elimination by 2021. • Outcomes: lower blood lead, crime‑rate correlations, cleaner air; future focuses on legacy soils, aviation gas, and battery recycling. 🌍
The Optical Telegraph: France’s 18th‑Century Internet
• Claude Chappe launched a tower network in 1790s France; messages hopped 30 km at a time. • Mechanized shutters/arms encoded alphabetic codes; operators relayed in minutes. • Killed by electric telegraph (wires, all‑weather) and labor cost; lives on as naval semaphore and in HCI metaphors. 🏰📡
