Wild Horses, Hidden Structures Behind Structures, Florida Flamingos. Feb 23, 2018, Part 1

The gentle curve of a beam. The particular shape of a clay brick. The sharp angles of a series of trusses. You might view these elements of buildings, bridges, and structures as part of the aesthetic and artistic design, or maybe you have overlooked them completely. But for London-based structural engineer Roma Agrawal, these visual charms play an important role not only in the beauty of a building, but in the physics that keep a structure from tumbling down. Agrawal reveals the hidden engineering and physics in the buildings and bridges around you. Until recently, scientists believed the only horses in the world left untouched by humans were the Przewalski subspecies, in central Asia. But now, researchers discover there are no more wild horses left anywhere on Earth. Do Florida's flamingos really belong there? New research argues that the colorful birds are a species native to Florida, and should be protected.
