Modern times calls for modern imagination and modern creativity solidly supported by modern materials and modern science, which results in modern architecture. Nowadays, rarely do people think about the enclosed public spaces they go in. Whether it be a sprawling mall or a high-rise building, an event stadium or a sporting arena, an airport or a train station, not too many people stop to consider the architectural, scientific and engineering marvels that went into its construction. There is such a huge visual and stylistic difference between the structures erected in the old times compared to the modern times. This is because the mastery of materials and physics has advanced to the point where construction is so much more efficient in all ways. Next time you go to a mall, or any of the enclosed spaces, take a look all around you, or better yet, look up, and you will see evidence of the building's modern marvels.
