Cosmic-ray astronomy  — Research Starter

Cosmic-ray astronomy is the study of high-energy particles originating from outer space, known as cosmic rays, which consist primarily of protons and other atomic nuclei. These particles provide…

Cosmic strings  — Research Starter

Cosmic strings are theoretical one-dimensional objects that may have formed shortly after the Big Bang, potentially playing a significant role in the structure of the universe as we know it. These…

Cosmic rays: composition and detection  — Research Starter

Cosmic rays are high-energy charged particles originating from outside the solar system, primarily composed of protons (about 87%), helium nuclei (around 12%), and a small percentage of heavier…

Coordinate systems used in astronomy  — Research Starter

Astronomical coordinate systems are methods used to locate celestial objects in the sky by assigning them two angular measurements. Each system is based on a reference plane and a reference direction,…

Controlled thermonuclear reactors  — Research Starter

Controlled thermonuclear reactors, commonly associated with nuclear fusion, are designed to harness the energy released when light nuclei, such as isotopes of hydrogen, combine to form heavier nuclei.…

Conserved quantities  — Research Starter

Conserved quantities are fundamental principles in physics that state certain physical properties remain constant in isolated systems, meaning they do not change despite physical processes. These…

Conductors and resistors  — Research Starter

Conductors and resistors are fundamental components of electrical systems, playing crucial roles in the transmission and regulation of electric current. Conductors are materials that allow electrons…

Conductors  — Research Starter

Conductors are materials, primarily metals, that allow electric current to flow through them easily due to their atomic structure. In conductors, particularly metals like copper and silver, conduction…

James Cameron  — Research Starter

James Cameron is a renowned Canadian filmmaker and producer celebrated for his significant contributions to the film industry, especially in the realm of special effects and storytelling. He gained…
