Burmese amber, also known as Burmite, is a type of fossilized tree resin that is found primarily in Myanmar (formerly known as Burma). This amber is notable for its age, with estimates placing it at around 99 million years old, dating back to the Cretaceous period. It is renowned for its preservation of ancient life forms, including a wide variety of inclusions such as insects, spiders, and plant material, making it valuable for both collectors and scientific research.
The Escucha Formation is a geological formation located in northern Spain, primarily in the region of Aragón. It is known for its sedimentary rock layers that date back to the Late Cretaceous period, which is approximately 100 to 66 million years ago. The formation is composed of a variety of rock types, including sandstone, siltstone, and claystone, and it is notable for its rich fossil content, which includes various types of marine and terrestrial organisms.
Grand Unification Energy (often referred to as the Grand Unification Scale) refers to the energy scale at which the strong, weak, and electromagnetic forces become unified into a single force within the framework of theoretical physics, particularly in Grand Unified Theories (GUTs). These theories propose that the three fundamental forces observed at lower energies merge into one force at extremely high energy levels.
Supergravity is a theoretical framework in physics that combines the principles of supersymmetry (SUSY) and general relativity. It is a type of gauge theory that extends the standard theories of gravity by incorporating additional symmetries that relate bosons (force-carrying particles) and fermions (matter particles).
The Wu experiment refers to a key scientific experiment conducted by physicist Chien-Shiung Wu in the 1950s that provided crucial evidence for the theory of parity violation in weak interactions. In the Wu experiment, which took place in 1956, Wu and her colleagues studied the beta decay of cobalt-60 (\(^{60}\)Co).
The Hybrid-pi model is an important conceptual and analytical framework used in the field of electronics, particularly in the analysis of bipolar junction transistors (BJTs) and, to some extent, field-effect transistors (FETs). It represents the transistor using a small-signal equivalent circuit that simplifies the analysis of its behavior in response to small variations in voltage and current around a bias point (operating point). ### Components of the Hybrid-pi Model 1.
The term "transistor diode model" can refer to a specific representation of a transistor's behavior using diode-like characteristics, particularly in the context of small-signal analysis or simplification of circuit models. Here's a breakdown of the concept: ### Transistor Basics A transistor is a semiconductor device used for amplification and switching. Bipolar junction transistors (BJTs) and field-effect transistors (FETs) are the two main types of transistors.
Tim Staffell is a British musician, best known as a singer, songwriter, and musician. He was a member of the band Smile, which was formed in the late 1960s and included future Queen members Freddie Mercury and Roger Taylor. Staffell's tenure with Smile was relatively brief, and he left the band before they eventually transitioned into Queen.
Henry Greenly is not widely recognized as a public figure or concept, and it is possible that you might be referring to a specific individual, character, or brand that is not well-documented.
Big Easel could refer to a couple of different things depending on the context: 1. **Art Supply/Tool**: In a general sense, a big easel is a large, often adjustable stand used by artists to hold a canvas while they paint. These easels can vary widely in design, material, and size, catering to different types of artwork and studio or outdoor settings.
The Big Pineapple is a large roadside attraction located in Woombye, Queensland, Australia. It was constructed in 1971 and stands approximately 16 meters (52 feet) tall. The structure is designed to resemble a pineapple, which is a significant agricultural product in the region, reflecting the local pineapple farming industry. The Big Pineapple serves as a tourist spot and is often visited by travelers seeking a quirky photo opportunity.
"The Big Pelican" could refer to various things depending on the context, such as a specific location, a piece of art, or a notable event or organization. However, without more specific context, it's challenging to provide a definitive answer.
Construct-Bots is a construction-themed toy line created by Hasbro, primarily featuring customizable action figures and robots. The concept allows children to build, customize, and play with their own robotic characters. The toys typically consist of various interchangeable parts, such as limbs, heads, and accessories, which can be combined in different ways to create unique designs. This encourages creativity and imaginative play.
Geomag is a brand of construction toys that consist of magnetic rods and metal spheres. These components can be combined in various ways to create three-dimensional structures, allowing players to explore concepts of geometry, physics, and creativity. The rods are typically made from a non-toxic plastic material and contain magnets at both ends, which connect to the metal spheres, enabling users to build shapes like towers, pyramids, and other complex designs.
Kid Spark Education is an organization focused on providing innovative educational resources and programs that engage students, particularly in the areas of science, technology, engineering, arts, and mathematics (STEAM). Their mission is to inspire and empower learners through hands-on, project-based learning experiences. Kid Spark's curriculum often includes kits and activities that promote critical thinking, creativity, and problem-solving skills. They aim to make STEAM education more accessible and enjoyable for early learners, usually targeting elementary school-aged children.
Loc Blocs is a brand of lightweight plastic building blocks designed for children. These blocks are specifically designed to promote creativity and imaginative play, allowing kids to build various structures and creations. They typically feature a unique interlocking mechanism, making them easy for small hands to use while providing stability to their builds. Loc Blocs can help in developing fine motor skills, spatial awareness, and cognitive abilities as children engage in hands-on construction activities.
Matador is a construction toy designed for building structures and models. It consists of various wooden rods and connectors that allow users to create stable, three-dimensional designs. The toy is known for its durability and versatility, allowing both children and adults to engage in creative and structural play. The design encourages spatial thinking, engineering skills, and creativity, making it popular in educational settings as well as for individual play.
Playmobil is a brand of toys produced by the German company geobra Brandstätter GmbH & Co. KG, which was founded in 1974.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
