Simplified model of cognitive processes associated with perception and memory

Cognition encompasses mental processes that acquire, store, retrieve, transform, or apply information. It is a pervasive part of mental life, helping individuals understand and interact with the world. Cognition includes perception, which organizes and interprets sensory input; memory, which stores and retrieves information; and thinking, which considers and manipulates ideas. Cognitive processes can be conscious or unconscious, and controlled or automatic. Classical computationalism conceives cognition as symbol-based rule processing, similar to how computers execute algorithms. Connectionism models the mind as a complex network of nodes where information flows as they communicate with each other. Many disciplines examine cognition, including psychology, neuroscience, and cognitive science. Its study originated in antiquity and has gained interdisciplinary prominence during the cognitive revolution in the 1950s. (Full article...)

Tracks of all cyclones in the 2002 Pacific hurricane season

Nineteen systems formed during the 2002 Pacific hurricane season, with fifteen further strengthening into named tropical storms; eight became hurricanes, of which six attained major hurricane status. The 2002 Pacific hurricane season consisted of the events that occurred in the annual cycle of tropical cyclone formation over the Pacific Ocean north of the equator and east of the International Date Line. The official bounds of each Pacific hurricane season are defined by the National Hurricane Center (NHC), beginning on May 15 in the Eastern Pacific and June 1 in the Central Pacific, and ending on November 30 in both areas. Activity in the 2002 season was generally near normal, with the number of tropical storms and hurricanes matching the respective 1991–2020 averages; however, the number of major hurricanes was above the average of four for the same period. Hurricanes Elida, Hernan, and Kenna achieved Category 5 strength on the Saffir–Simpson scale, tying a record set in 1994 for the most storms to do so in one season since reliable records began in 1971.

Today's featured picture

Glaucus atlanticus, commonly known as the blue dragon, is a species of sea slug in the family Glaucidae. It is pelagic and found in tropical and temperate oceans worldwide. The species floats upside down at the ocean's surface using a gas-filled sac in its stomach, with blue and silver countershading to help camouflage it from predators. It preys on venomous cnidaria such as the Portuguese man o' war, storing the prey's stinging nematocysts in specialised sacs for its own defence. Handling the slug can result in a painful sting and symptoms such as nausea and allergic contact dermatitis. This G. atlanticus sea slug, about 35 millimetres (1.4 in) in length, was found washed up on a beach at Surfers Paradise in Queensland, Australia.
