Technology & Innovation
Inventions, engineering, the internet and the machines we built.
Technology quizzes date badly, so these concentrate on the parts that do not: how something works, why it was invented, and what problem it was solving.
The section covers inventions and engineering, the internet and how it is actually held together, robotics and artificial intelligence, and general technology from ancient tools to current hardware. A question about a protocol or a bridge or a printing press is really a question about a constraint someone had to design around, and that is what the explanations focus on.
This is one of the smaller sections and it grows as new quizzes are written.
