Material Science is an interdisciplinary field which involves the discovery and designing of materials. Material physics incorporates the application of physics, chemistry and engineering to understand the behavior of materials. The innovations and inventions from the stone tools in the prehistoric era to silicon chips and silicon solar cells in our modern era are from the understanding of material science. The material scientists work with various materials and chemicals for the betterment of human life. They also conduct experiments on different materials in different conditions to determine the effect on that material. The advances in nanotechnology, polymers and ceramics, and biomaterials are from the evolution of material physics.
