Brilliant documentary series.Big, Bigger, Biggest each episode examines a current engineering marvel, ideally the biggest of that ever built. It then traces back all the leaps forward in technology and innovation, through looking at the then-marvels/"biggest"s of that type and the revolutionary progress they brought. Items covered include: tunnels, towers, oil rigs, bridges, telescopes, dams and cruise liners (to name but a few).Incredibly well researched. Well told too: you are never blinded by the maths or other theory involved, so most people should be able to follow. Very stirring stuff, as you come to appreciate just how innovative and intelligent the designers of each leap of progress were. Even the peripheral engineering reminds us of what a clever and resourceful age we live in, and how ingenious people can be.Good graphics and scaled-down practical experiments illustrate the phenomena and theories at work very well.So good, each episode makes me want to be an engineer...
