I just learned that surfers sometimes use artificial waves, like those made by boats or by machines in pools?
However, surfers can also utilize artificial waves such as those from boat wakes and the waves created in artificial wave pools.

Surfing
Surfing is a surface water sport in which the wave rider, referred to as a surfer, rides on the forward or deep face of a moving wave, which is usually carrying the surfer towards the shore. Waves suitable for surfing are primarily found in the ocean, but can also be found in lakes or in rivers in the form of a standing wave or tidal bore. However, surfers can also utilize artificial waves such as those from boat wakes and the waves created in artificial wave pools. The term "surfing" refers to the act of riding a wave, regardless of whether the wave is ridden with a board or without a board, and regardless of the stance used.
Artificial wave
Artificial waves are man-made waves usually created on a specially designed surface or in a pool. Surface waves can be created by any moving object displacing fluid: turbine blades, paddles, a hand, a flung stone, etc. Each pulse of water (or crest) pushed outward from the disturbance leaves a space (or trough) behind it which causes another, smaller pulse to follow: thus a thrown stone's single impact causes a series of ripples. Larger waves can be built up if a series of movements are timed to reinforce waves' motion, much like a person sliding back and forth in a bathtub. Boundaries and obstacles also shape waves by concentrating or dissipating some of the wave's energy.
Artificial intelligence
Artificial intelligence (AI, also machine intelligence, MI) is intelligence displayed by machines, in contrast with the natural intelligence (NI) displayed by humans and other animals. In computer science AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving". See glossary of artificial intelligence.
Surf break
A surf break (also break, shore break, or big wave break) is a permanent (or semi permanent) obstruction such as a coral reef, rock, shoal, or headland that causes a wave to break, forming a barreling wave or other wave that can be surfed, before it eventually collapses. The topography of the seabed determines the shape of the wave and type of break. Since shoals can change size and location, affecting the break, it takes commitment and skill to find good breaks. Some surf breaks are quite dangerous, since the surfer can collide with a reef or rocks below the water. Surf breaks may be defended vehemently by surfers, as human activities and constructions can have unintended and unpredictable consequences which can be either positive, negative, or unknown.
Surf culture
Surf culture is the culture that includes the people, language, fashion, and lifestyle surrounding the sport of surfing. The history of surfing began with the ancient Polynesians. That initial culture directly influenced modern surfing, which began to flourish and evolve in the early 20th century, with its popularity spiking during the 1950s and 1960s (principally in Hawaii, Australia, and California). It has affected music, clothing fashion, literature, film, art, and youth jargon in popular culture' the number of surfers throughout the world continues to increase. Surfers' desire for the best possible waves to ride make them dependent on conditions that may change rapidly, given the unpredictable nature of weather events and their effect on the surface of the ocean.
Artificial turf
Artificial turf is a surface of synthetic fibers made to look like natural grass. It is most often used in arenas for sports that were originally or are normally played on grass. However, it is now being used on residential lawns and commercial applications as well. The main reason is maintenance—artificial turf stands up to heavy use, such as in sports, and requires no irrigation or trimming. Domed, covered, and partially covered stadiums may require artificial turf because of the difficulty of getting grass enough sunlight to stay healthy. Artificial turf does have its downside, however: limited life, periodic cleaning requirements, petroleum use, toxic chemicals from infill, and heightened health and safety concerns.
List of Dutch inventions and discoveries
The Netherlands had a considerable part in the making of modern society. The Netherlands and its people have made numerous seminal contributions to the world's civilization, especially in art, science, technology and engineering, economics and finance, cartography and geography, exploration and navigation, law and jurisprudence, thought and philosophy, medicine, and agriculture. Dutch-speaking people, in spite of their relatively small number, have a significant history of invention, innovation, discovery and exploration. The following list is composed of objects, (largely) unknown lands, breakthrough ideas/concepts, principles, phenomena, processes, methods, techniques, styles etc., that were discovered or invented (or pioneered) by people from the Netherlands and Dutch-speaking people from the former Southern Netherlands ("Zuid-Nederlanders" in Dutch).

Why? Is it to practice when there are no waves ?
