Smart materials are materials that have properties that can change in response to external stimuli or environmental conditions. These stimuli can include temperature, pressure, electric or magnetic fields, humidity, and light, among others. The ability to change their properties makes smart materials particularly useful in various applications, including sensors, actuators, and other advanced technologies. Some common types of smart materials include: 1. **Shape Memory Alloys (SMAs)**: These metals can return to a predefined shape upon heating.

The Soai reaction is a notable organic chemical reaction that involves the asymmetric synthesis of prochiral β-amino alcohols via the addition of a chiral catalyst to a prochiral substrate. It was first reported by Japanese chemist Shohei Soai and his colleagues in 1995.

A social experiment is a research method used to study behavioral, social, or psychological phenomena by observing the reactions of individuals or groups in a controlled setting. It typically involves manipulating certain variables while keeping others constant to see how these changes affect participants' attitudes, behaviors, or interactions. Social experiments can take many forms, including: 1. **Field Experiments**: Conducted in real-world settings, such as public places or communities, to understand how people behave in natural environments.

As of my last knowledge update in October 2021, I do not have any specific information about "Sofia Feltzing." It is possible that she is a private individual, a public figure that has emerged after that date, or perhaps a character in a work of fiction or other media.

A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or part of the Sun's light from reaching the Earth. This phenomenon can happen only during a new moon phase, and there are three main types of solar eclipses: 1. **Total Solar Eclipse**: This occurs when the Moon completely covers the Sun, as viewed from Earth.

Bamboozle! is a classic party game that combines elements of trivia and skill, often incorporating a range of topics and challenges. Players typically answer questions and complete tasks to move through the game, with the goal of outsmarting their opponents. The game is known for its humorous and sometimes silly nature, making it a fun choice for groups of friends or family gatherings.

The term "Soviet astrophysicists" refers to scientists and researchers in the Soviet Union who specialized in the field of astrophysics, which is the branch of astronomy that deals with the physical properties and underlying processes of celestial objects and phenomena. The Soviet Union, particularly during its space exploration era from the 1950s to the 1980s, made significant contributions to astrophysics and related fields.

The term "span" can refer to different concepts depending on the context. Here are two primary interpretations of "span" as a unit of measurement: 1. **Span as a Measurement of Length**: In the context of physical measurements, a "span" is often considered to be the distance between the tip of the thumb and the tip of the little finger when the hand is fully outstretched. Traditionally, this measurement is about 9 inches (approximately 22.

"Speeches by orator" typically refers to the oratory works delivered by individuals renowned for their public speaking abilities. These speeches are often characterized by their rhetorical quality, persuasive language, and emotional appeal. Orators may include historical figures, politicians, activists, and influential speakers who have addressed audiences on various topics, such as civil rights, social justice, war, and peace. Some notable orators and their famous speeches include: 1. **Martin Luther King Jr.

In Austria, speed limits for vehicles vary based on the type of road and vehicle. Here are the general speed limits: 1. **Motorways (Autobahnen)**: - Cars: 130 km/h (81 mph) is the recommended maximum speed, although there is no enforced limit on certain sections. - Trucks and buses over 3.5 tons: 100 km/h (62 mph).

Spherical harmonics are a set of mathematical functions that are defined on the surface of a sphere and are used in a variety of fields, including physics, engineering, computer graphics, and geophysics. They can be viewed as the multidimensional analogs of Fourier series and are particularly useful in solving problems that have spherical symmetry.

Spin canting is a phenomenon observed in magnetic materials, particularly in antiferromagnets, where the spins of magnetic moments deviate from perfect alignment along a particular axis. In an ideal antiferromagnet, adjacent spins are oriented in exactly opposite directions, resulting in no net magnetization.

Spinor spherical harmonics are mathematical functions that arise in various domains of physics, particularly in quantum mechanics and the theory of angular momentum. They are a generalization of conventional spherical harmonics and are used to represent the states of spinning particles, such as fermions, in a way that takes into account their intrinsic spin.

Spontaneous absolute asymmetric synthesis refers to a process in which an achiral compound spontaneously transforms into a chiral product without the influence of any external chiral environments or catalysts. In other words, it describes a scenario where an achiral precursor can lead to the formation of a chiral product in a way that does not require any external chiral sources or conditions.

Sports figurines are collectible figurines or statues that represent athletes, sports heroes, or sporting events. They are usually made from materials like plastic, resin, metal, or ceramic and can vary in size from small collectible models to larger display pieces. Sports figurines often depict players in action poses, celebrating significant moments in sports history, or showcasing specific teams and sports disciplines. These figurines are popular among fans of various sports, including baseball, basketball, football, hockey, soccer, and more.

A Williamson amplifier is a type of audio power amplifier designed in the 1940s by British engineer Harold Stephen Williamson. It is known for its high fidelity and is notable for its use in vacuum tube audio amplification, making it popular among audiophiles and in high-quality audio applications. The Williamson amplifier features a push-pull output stage typically using vacuum tubes, which helps to reduce distortion while delivering high power.
