The rebound effect can occur when a drug is stopped, causing symptoms to return more severely, or when a drug is used to treat worsening symptoms. Many drugs, including anti-anxiety drugs, sleep medications, and pain relievers, can cause rebound effects. Discontinuing use and consulting a physician is important to find alternative treatments. The bounce effect […]
The Leidenfrost effect occurs when a liquid is exposed to extreme heat, creating a layer of vapor that slows evaporation. It is named after Johann Gottlob Leidenfrost and has practical applications in cooling systems. However, it can also be dangerous and requires proper safety precautions. The Leidenfrost effect is a physical phenomenon that occurs when […]
The lunar effect is the belief that the moon’s phases affect human behavior, causing negative events such as homicides, suicides, and domestic violence. However, scientific studies have found no link between the lunar cycle and these consequences. The belief is perpetuated through anecdotes and media sensationalism, but studies have confirmed that it is non-existent. The […]
The Flynn effect is a global phenomenon where IQs of the population increase over time. James R. Flynn is the recognized proponent, collecting data from around the world since the 1980s. The cause of the increase is unknown, but factors such as education, nutrition, and environment may contribute. Genetics also play a role. Intelligence tests […]
Jean Charles Athanase Peltier accidentally discovered the Peltier effect while investigating electricity. He connected copper and bismuth wires to a battery, causing one junction to get hot and the other to get cold. This effect can be used for refrigeration, but is inefficient and has other disadvantages. Despite this, it has great technological potential and […]
The Seebeck effect, discovered in 1821 by Thomas Johann Seebeck, converts temperature differences between two dissimilar metals in a circuit into an electric current. The Peltier effect and Thomson effect are related phenomena. Thermocouple thermometers use these effects to convert thermal potential difference into electrical potential difference. The Seebeck effect describes a thermoelectric phenomenon by […]
The Coanda effect causes fluid or gas to hug a convex surface, discovered by Henri-Marie Coanda in the 1930s. This principle is relevant to aircraft design, including the Coanda thruster and circulation control wing technology. The science behind this effect is known as fluid dynamics. The Coanda effect states that a stream of fluid or […]
The shielding effect is the decrease in attraction between electrons and the nucleus in an atom due to repulsive forces between electrons. It mainly applies to valence electrons and is stronger for electrons in outer orbits. The strength of the effect can be estimated using the periodic table and affects ionization energy. Shielding is important […]
The Bernoulli effect is a principle discovered by Daniel Bernoulli in 1738 that describes the relationship between flow velocity and pressure in fluid systems. As the velocity of horizontal flow through a fluid increases, the pressure decreases. This effect can be observed in both hydrodynamic and aerodynamic systems, and is used in real-world applications such […]
The stroboscopic effect is when the brain interprets movement based on rapid but episodic retinal information. Strobes can control what the eye sees of a moving object, creating an optical illusion. The effect is most clearly demonstrated by repetitive objects, including those that move in cycles. The “wagon wheel effect” occurs when a video camera […]
The Josephson effect involves paired electrons passing through a thin insulating barrier between superconductors, with no voltage drop below a critical current. It can be controlled by a magnetic field and used for measurements, data storage, and low-power generators. Josephson junctions can switch signals faster than other semiconductor switches, making them useful in computing and […]
Hall effect sensors measure magnetic fields using the Hall effect. They come in analog and digital forms and can be used for speed, direction, and position sensing. They are used in automobiles, computers, and portable devices and are cost-effective. A Hall effect sensor is a small device, mounted on a printed circuit board, capable of […]
The greenhouse effect of global warming occurs when excess greenhouse gases trap heat in the Earth’s lower atmosphere, causing the planet to become hotter. Humans contribute to this effect by emitting carbon dioxide through burning fossil fuels and deforestation. The greenhouse effect can cause climate change, affect crop growth, and lead to rising sea levels […]
A cause-and-effect thesis presents an argument in terms of one or more causes and effects, usually in a cause-and-effect article. It should be an opinion supported by evidence, and can vary in complexity. It is important to present one or more causes and effects that will be discussed in the article. A cause-and-effect thesis is […]
The chilling effect is a legal tactic used to silence critics through lawsuits or threats of legal action. It poses a challenge to free speech, even in countries with strong laws protecting it. The American Civil Liberties Union defends individuals on the basis of free speech. A court case is not always necessary to produce […]
The CSI effect is a shift in attitudes towards forensic science due to TV dramas, which can lead to jurors expecting more forensic evidence and potentially impacting criminal activity. However, the idealized portrayal of forensics can create false expectations and trust, leading to wrongful convictions or false acquittals. Criminals may also be influenced by the […]
Disparate impact in employment practices that negatively affect a protected class can result in violation of equal protection rules, leading to litigation, fines, and penalties. US civil rights laws protect minorities, disabled, and older Americans from discrimination in any aspect of work. Tests or qualifications that unfairly impact a protected class are not allowed, except […]
The Hawthorne effect is the increase in productivity resulting from observation by management or researchers. The effect was discovered in experiments conducted between 1924 and 1932 at the Hawthorne Works plant. The experiments tested various factors, and lead researcher Elton Mayo concluded that productivity depended on organizational sociology. The Hawthorne effect was only isolated and […]
The generation effect is a cognitive psychology phenomenon where active participation in generating information leads to better memory retention. This has implications for teaching and learning, with note-taking and writing exercises being more effective than passive reading. The effect is weaker in patients with cognitive impairments. The generation effect is a phenomenon observed in cognitive […]
The photoelectric effect is the phenomenon where electrons are emitted from a metal surface when light shines on it. It was first explained by Albert Einstein in 1905. https://x-playn/cose-leffetto-fotoelettrico
