Cascade, or Cascading may refer to: Science and technology Science * Air shower (physics), a cascade (particle shower) of subatomic particles and ionized nuclei **Particle shower, a cascade of secondary particles produced as the result of a high-energy particle interacting with dense matter * Cascade, the CRISPR-associated complex for antiviral defense (a protein complex) * Cascade (grape), a type of fruit *Cascade waterfalls, or series of waterfalls * Biochemical cascade A biochemical cascade, also known as a signaling cascade or signaling pathway, is a series of chemical reactions that occur within a biological cell when initiated by a stimulus. This stimulus, known as a first messenger, acts on a receptor that ..., a series of biochemical reactions, in which a product of the previous step is the substrate of the next * Collision cascade, a set of nearby adjacent energetic collisions of atoms induced by an energetic particle in a solid or liquid * Ecological cascade, a series ...

Air Shower (physics)
Air showers are extensive Particle shower, cascades of subatomic particles and ionized nuclei, produced in the Earth's atmosphere, atmosphere when a ''primary'' cosmic ray enters the atmosphere. Particles of cosmic radiation can be protons, Atomic nucleus, nuclei, electrons, photons, or (rarely) positrons. Upon entering the atmosphere, they interact with molecules and initiate a particle cascade that lasts for several generations, until the energy of the primary particle is fully converted. If the primary particle is a hadron, mostly light mesons like pions and kaons are produced in the first interactions, which then fuel a hadronic shower component that produces shower particles mostly through pion decay. Primary photons and electrons, on the other hand, produce mainly electromagnetic showers. Depending on the energy of the primary particle, the detectable size of the shower can reach several kilometers in diameter. The air shower phenomenon was unknowingly discovered by Bruno Ro ...
