Still the best non-fiction TV ever produced in my opinion (the whole series I mean).

The Day the Universe Changed (also by Burke) was also exceptionally good.

Similar premise, but focusing more on philosophy and understanding, and not tracking linearly through time.

There were another two Connections mini-series, though they were IMO not up to the mark of the first. Good, but not truly excellent.
