The College of Sciences at San Diego State University was officially established in 1931. Over the years, the technology and tools used for the College’s joint missions of teaching and creating new knowledge have advanced significantly.

The spherical shape is an improvement over the dodecahedron and is capable of projecting between 1500 and 6000 stars, depending on the setup. Photo Credit: Charlie Neuman, San Diego Union Tribune
2022: SDSU biology students identify similarities and differences between skulls of cetaceans – whales, dolphins and porpoises. Several of the skulls are replicas, made of resin, that are less delicate to handle.
