What’s Ray Tracing?

Ray tracing is a method for creating realistic 3D computer graphics images by simulating the path of light as it interacts with objects. It is used during rendering and can make scenes look more realistic, but is hardware intensive and not commonly used for real-time graphics. The process involves modeling objects, applying lighting and camera […]

What’s a high-energy cosmic ray?

Cosmic rays are energetic particles that can be detected when they collide with the upper atmosphere, allowing us to infer their energy and direction. Ultrahigh-energy cosmic rays (UHECRs) are those that exceed the Greisen-Zatsepin-Kuzmin (GZK) limit, and their existence is a mystery that may hint at new physical theories. The Oh-My-God particle, observed in 1991, […]

What’s gamma ray recording?

Gamma ray recording measures natural radioactivity in the ground, with a high correlation to sediment- and clay-rich rocks called shales, indicating nearby oil and natural gas deposits. Geologists drill boreholes and use probes to measure gamma rays at different depths, with spectral recording identifying different types of radiation. Gamma ray recording can also be used […]

What’s the Compton Gamma Ray Observatory?

The Compton Gamma Ray Observatory, launched in 1991, used scintillators to record gamma rays from astronomical events such as gamma-ray bursts and thunderclouds. It discovered soft gamma repeaters, believed to be magnetars, and completed a survey of pulsars and supernova remnants before being deorbited in 2000. The Compton Gamma Ray Observatory is a space telescope […]

What’s a gamma ray?

Gamma rays are the highest energy and shortest wavelength electromagnetic radiation, with a wavelength of less than 1 picometer. They are generated in energetic events and can penetrate through thick shields. Gamma rays are ionizing radiation and can strip electrons from atoms, causing disruptions. Gamma ray bursts are the most energetic activity in the universe […]
