Urban Illusions

Street artists use the city as their canvas

Join Our Community of Science Lovers!

The life of our city is rich in poetic and marvelous subjects. We are enveloped and steeped as though in an atmosphere of the marvelous; but we do not notice it. —Charles Baudelaire, 1846

Urban landscapes are embodiments of human aspirations and dreams. They represent the spirit of an age and personify the minds and hearts of the people who inhabit them. Archaeological excavations of ancient cities, such as the magnificently preserved ruins of Pompeii and Herculaneum, bring to life our distant past. If we could peer into the future, we would want to know what our cities will look like to understand who we will become.

Cities capture our imagination in fascinating ways. Art and folklore are chock-full of mythical and imaginary cities, from the sunken lost city of Atlantis and El Dorado's city of gold to Fritz Lang's dystopian film Metropolis and, more recently, the Escheresque architecture of the folding cityscapes in the movie Inception. Yet we need not turn to fiction or travel far in space or time to experience the wonder. Even the most desolately functional urban environments can be sprinkled with nuggets of magic and surprise, with illusion “Easter eggs” that challenge our perception of what's real.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
