Technological History

The tread wheel crane harnessed human power through gear ratios, enabling small crews to lift massive stones and revolutionize cathedral construction logistics.

Exploring the engineering innovations that transformed medieval architecture, from rib vaults to stained glass, revealing how structural ingenuity built Europe's cathedrals.

The rib vault revolutionized Gothic architecture by channeling roof loads precisely, enabling soaring heights and expansive stained glass windows that transformed cathedral interiors.

A three-part investigation into the de Havilland Comet 1, the world's first jet airliner, and the scientific detective work that uncovered the hidden physics of pressurized flight.

A photo gallery of the Comet disaster.

An investigation into the flawed testing protocols that masked the Comet’s vulnerability and how a single prototype’s survival doomed the production fleet.

A technical deep dive into the 1954 water tank experiments and how the squarish windows of the Comet turned air pressure into a structural saw.

An analysis of the three catastrophic break-ups in Calcutta, Elba, and Naples, and the institutional tendency to blame the weather when the machine is failing.

The final evolution of the T-34 platform and its enduring impact on modern armored warfare.

Examining the ergonomic challenges and human factors that made the T-34 a difficult but effective weapon system.
