Glass formation is the process by which certain materials transition from a liquid state to a solid state without crystallizing. This results in a non-crystalline or amorphous solid known as glass. Unlike crystalline solids, which have a well-defined and ordered structure, glass has a disordered arrangement of molecules, giving it unique physical properties. The glass formation process typically involves: 1. **Cooling a Liquid**: As a liquid is cooled, its viscosity increases.
Smart glass, also known as switchable glass or electrochromic glass, refers to a type of glass that can change its properties in response to an external stimulus, such as an electrical current, heat, or light. This technology is often used to modify light transmission, privacy, and temperature control in architectural applications. There are various types of smart glass, each operating on different principles: 1. **Electrochromic Glass**: This type changes color or opacity when a small voltage is applied.
A crypton is a hypothetical elementary particle proposed in some theories related to quantum mechanics and theoretical physics. The term "crypton" has been used in various contexts, but it's not a standard or widely accepted term in particle physics. One notable use of "crypton" is in the context of certain speculative theories about dark matter or new physics beyond the Standard Model.
Photinos are hypothetical elementary particles predicted by some theories in particle physics, particularly those related to supersymmetry (SUSY). In these theories, every known particle has a corresponding "superpartner" that differs in spin by a half-unit. While the photon is a massless gauge boson with a spin of 1 that mediates electromagnetic interactions, the photino would be the supersymmetric partner of the photon and would have a spin of 1/2.
Saxion is a university of applied sciences located in the Netherlands, specifically in the regions of Deventer, Enschede, and Apeldoorn. It offers a wide range of undergraduate and postgraduate programs across various fields such as technology, health care, business, and social sciences. Saxion emphasizes practical experience and collaboration with businesses, providing students with opportunities to engage in internships and projects that enhance their skills in a real-world context.
Stable massive particles are particles that have mass and do not decay into other particles over measurable timescales. In the context of particle physics, stability generally refers to the particle's lifetime being significantly longer than the time scales of experiments or the age of the universe.
W′ and Z′ bosons are hypothetical particles that extend the Standard Model of particle physics. They are often associated with theories that go beyond the Standard Model, such as certain Grand Unified Theories (GUTs) and models that include additional symmetries. 1. **W′ Boson**: The W′ boson is a heavier cousin of the W boson, which is responsible for mediating the weak nuclear force in the Standard Model.
Tachyons are hypothetical particles that are theorized to travel faster than the speed of light. The concept arises from certain solutions to the equations of special relativity, which suggest that if such particles exist, they would have some counterintuitive properties. For example, tachyons would have an imaginary rest mass and could never slow down to or below the speed of light. Tachyons have not been observed in experiments, and their existence remains purely speculative.
Loop quantum gravity (LQG) is a theoretical framework that aims to reconcile general relativity (GR) and quantum mechanics (QM) into a theory of quantum gravity. Its development has a rich history that spans several decades, marked by significant contributions from various physicists. Here’s an overview of its timeline and key milestones: ### 1.
LUGNET, or the LEGO User Group Network, is an online community and resource hub for LEGO enthusiasts, particularly those who participate in or organize LEGO-related events, discussions, and activities. It serves as a platform for fans of LEGO to connect, share ideas, showcase their creations, and collaborate on projects. The network includes various user groups that represent different geographical locations and interests within the LEGO fandom.
CACNG4, or Calcium Voltage-Gated Channel Auxiliary Subunit Gamma 4, is a gene that encodes a protein involved in the regulation of calcium channels. Specifically, it is a part of the auxiliary subunit family of voltage-gated calcium channels. These channels play crucial roles in various physiological processes, including muscle contraction, neurotransmitter release, and gene expression.
Loop quantum cosmology (LQC) is a theoretical framework that applies the principles of loop quantum gravity (LQG) to cosmological models, particularly in the context of the early universe. LQG is a theory that attempts to unify general relativity and quantum mechanics, particularly in the realm of gravity. In LQG, spacetime is quantized, meaning that it is described in terms of discrete structures rather than continuous ones.
A steam rocket is a type of rocket that uses steam as its propulsion mechanism. The concept is based on the principles of steam engines and thermodynamics. In a steam rocket, water is heated to generate steam, which then expands and is expelled through a nozzle to produce thrust.
The FIRST Championship is an annual event organized by FIRST (For Inspiration and Recognition of Science and Technology), a non-profit organization aimed at inspiring young people's interest and participation in science and technology through robotics competitions. The championship typically serves as the culmination of several FIRST robotics competition seasons, including FIRST Robotics Competition (FRC), FIRST Tech Challenge (FTC), and FIRST Lego League (FLL), among others. During the FIRST Championship, teams from around the world come together to compete in their respective categories.
Lego-Brücke, or "Lego Bridge," refers to a project or activity involving the construction of bridges using LEGO bricks. This concept is often used in educational settings to teach principles of engineering, architecture, and physics. Participants, such as students, are encouraged to design and build their own bridges, which can be tested for strength and stability. The projects can vary from simple bridge designs to more complex structures, and they often incorporate competition elements, such as weight-bearing tests or aesthetic evaluations.
Lego House, located in Billund, Denmark, is an interactive experience center dedicated to the LEGO brand and its creative potential. Opened in September 2017, it serves as a celebration of creativity, play, and learning, offering a range of activities and exhibits centered around LEGO bricks. The facility is designed to resemble a stack of oversized LEGO bricks and includes various interactive zones where visitors can engage in hands-on building activities, explore different themes, and participate in creative challenges.
The Lego Group is a privately held company based in Denmark, known primarily for its production of LEGO-branded toys. Founded in 1932 by Ole Kirk Christiansen, the company originally manufactured wooden toys and household items before shifting focus to plastic building bricks in 1949. The iconic interlocking plastic bricks, commonly referred to as LEGO bricks, have become popular worldwide, fostering creativity and imagination among children and adults alike.
"Buddy Lee" can refer to a few different things depending on the context. Here are some possibilities: 1. **Buddy Lee (Character)**: In popular culture, Buddy Lee is often known as an advertising character used by the Lee Jeans brand. He is depicted as a rugged and laid-back cowboy persona, representing the brand's durable and stylish denim.
"Jumeau" refers to a brand of French dolls that were produced in the late 19th and early 20th centuries. The most notable aspect of Jumeau dolls is their high quality and craftsmanship, often characterized by realistic facial features, fine porcelain heads, and intricate jointed bodies. These dolls were typically made by the Jumeau company, which was founded by the doll maker Pierre-François Jumeau.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
