The first essay tells us how a Canadian virgin forest was transformed into a thriving metropolis of Vancouver. We can trace its history back to the late 18th century, when the city's site was first discovered. In the second essay, the author discusses the new rockets for the new space age.

The last essay is about a digital transformation of the world economy. From various aspects, the three essays have provided insights into mankind's never-ending quest for the new.
