The 20th century is undoubtedly one of the most amazing periods of our race. In those 100 years, we went from horses to cars, from mail to email, from dream to radio and television, movies and video games. Our world, for good or bad, went from analog to digital that century, and is continuing that journey now. It was also a century of two world wars, of unimaginable loss and uncalculable gain. Some countries disappeared, while others were born or reborn. Art, science, the very way we conceive ourselves. And all of this is but the tip of the iceberg when describing this century, the century of change.
