A Gateway to a Science Center: Design inspired by science, sustainability, monumentality and engineering. The gateway is designed to be a monumental piece of architecture based on multiple scientific principles including climatology, sun path, physics, material science. The smaller of the two catenary arches is designed to rotate along a circular path, the arches are held together with a series of large scale scissor hinges that enable movement. The rotation of the smaller arch follows the sun path through the course of a day and the moon path at night. The gateway serves as an exhibit to communicate scientific principles.
