The Racah Institute of Physics aspects related to high-Tc superconductivity. On the experimental side, benefiting from the facilities of the Harvey M. Krueger center for nanoscience and nanotechnology, researchers apply modern measuring and fabrication techniques to study the physics of nano-structures, their application to quantum information processing, the interaction of light and matter, high-Tc superconductivity, and the physics of electron glasses. More specifically, and summarizing but a few of the research directions, researchers study excitonic fluids in semiconductor nanostructures with an eye on both a better physical understanding of their macroscopic quantum coherence properties and possible future applications in electro-optic devices.

Physics in the medieval Islamic world physics from the Greeks and during the Islamic Golden Age developed it further, especially placing emphasis on observation and "a priori" reasoning, developing early forms of the scientific method. With Aristotelian physics, physics was seen as lower than demonstrative mathematical sciences, but in terms of a larger theory of knowledge, physics was higher than astronomy; many of whose principles derive from physics and metaphysics. The primary subject of physics, according to Aristotle, was motion or change; there were three factors involved with this change, underlying thing, privation, and form. In his "Metaphysics", Aristotle believed that the "Unmoved Mover" was responsible
