>Quantum mechanics, also known as quantum physics, is the fundamental physical theory that describes the behavior of matter and of light; the behaviors it models typically occur at and below the scale of atoms, and have often been described as counterintuitive.[2]: 1.1 Its concepts and methods have been applied across many disciplines, including quantum chemistry, quantum biology, quantum field theory, quantum technology, and quantum information science.
>Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale; however, it is insufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Classical mechanics can be derived from quantum mechanics as an approximation that is valid at ordinary scales.[3]
>Quantum systems have bound states that are quantized to discrete values of energy, momentum, angular momentum, and other quantities, in contrast to classical systems where these quantities can be measured continuously. Measurements of quantum systems show characteristics of both particles and waves (wave–particle duality), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial conditions (the uncertainty principle).
>Quantum mechanics arose gradually from theories to explain observations that could not be reconciled with classical physics, such as Max Planck's solution in 1900 to the black-body radiation problem, and the correspondence between energy and frequency in Albert Einstein's 1905 paper, which explained the photoelectric effect. These early attempts to understand microscopic phenomena, now known as the "old quantum theory", led to the full development of quantum mechanics in the mid-1920s by Niels Bohr, Erwin Schrödinger, Werner Heisenberg, Max Born, Paul Dirac and others. The modern theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical entity called the wave function provides information, in the form of probability amplitudes, about what measurements of a particle's energy, momentum, and other physical properties may yield.

>San Tomas Aquinas Creek, known locally as San Tomas Aquino Creek, is a 13.6-mile-long (21.9 km) stream[2] that heads on El Sereno mountain in El Sereno Open Space Preserve in Saratoga in Santa Clara County, California, United States. It flows north through the cities of Saratoga, Monte Sereno, Los Gatos, Campbell, and Santa Clara, where it joins Saratoga Creek, which in turn, flows to the Guadalupe Slough and south San Francisco Bay.

>Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor. They are typically 50 to 100 kilometers (30 to 60 mi) wide and 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about 50,000 km (31,000 mi) of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 10,994 m (36,070 ft) below sea level.
>Oceanic trenches are a feature of the Earth's distinctive plate tectonics. They mark the locations of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year. Oceanic lithosphere moves into trenches at a global rate of about 3 km2 (1.2 sq mi) per year.[1] A trench marks the position at which the flexed, subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to and about 200 km (120 mi) from a volcanic arc.
>Much of the fluid trapped in sediments of the subducting slab returns to the surface at the oceanic trench, producing mud volcanoes and cold seeps. These support unique biomes based on chemotrophic microorganisms. There is concern that plastic debris is accumulating in trenches and threatening these communities.

>Technological utopianism, often called techno-utopianism or technoutopianism, is any ideology based on the premise that advances in science and technology could and should bring about a utopia, or at least help to fulfill one or another utopian ideal. A techno-utopia is therefore an ideal society, in which laws, government, and social conditions are solely operating for the benefit and well-being of all its citizens, set in the near- or far-future, as advanced science and technology will allow these ideal living standards to exist; for example, post-scarcity, transformations in human nature, the avoidance or prevention of suffering and even the end of death. Technological utopianism is often connected with other discourses presenting technologies as agents of social and cultural change, such as technological determinism or media imaginaries.[1]
>A tech-utopia does not disregard any problems that technology may cause,[2] but strongly believes that technology allows mankind to make social, economic, political, and cultural advancements.[3] Overall, Technological Utopianism views technology's impacts as extremely positive. In the late 20th and early 21st centuries, several ideologies and movements, such as the cyberdelic counterculture, the Californian Ideology, cyber-utopianism, transhumanism,[4] and singularitarianism, have emerged promoting a form of techno-utopia as a reachable goal. The movement known as effective accelerationism (e/acc) even advocates for "progress at all costs".[5] Cultural critic Imre Szeman argues technological utopianism is an irrational social narrative because there is no evidence to support it. He concludes that it shows the extent to which modern societies place faith in narratives of progress and technology overcoming things, despite all evidence to the contrary.[6]
