Gravity-vacuum transit (GVT) is a proposed transportation system that combines elements of gravitational forces and vacuum technology to create efficient, high-speed travel over long distances. The concept is often associated with proposals for advanced public transportation systems that use magnetic levitation with low air resistance to facilitate rapid transit.
The Freedom Riders were a group of civil rights activists who rode interstate buses into the segregated southern United States in 1961 to challenge and protest against racial segregation in public transportation. This initiative was part of a broader effort to combat Jim Crow laws and promote civil rights for African Americans. The Freedom Rides began on May 4, 1961, organized by the Congress of Racial Equality (CORE) and included both Black and white activists.
The Montgomery Bus Boycott was a pivotal civil rights protest that took place in Montgomery, Alabama, from December 5, 1955, to December 20, 1956. It was initiated in response to the arrest of Rosa Parks, an African American woman who refused to give up her seat to a white person on a segregated bus. Her act of civil disobedience became a catalyst for the boycott.
The Indonesian used train import controversy refers to the issue surrounding the importation of used trains into Indonesia, which has raised concerns about safety, environmental impact, and the effectiveness of regulations. This controversy centers on the balance between modernizing Indonesia's railway system and the potential risks associated with importing older, used trains from other countries. Key points of the controversy include: 1. **Safety Concerns**: Critics argue that older trains may not meet current safety standards.
"Rescue of Sea Nymph" typically refers to a famous painting by the artist William H. Huddle, created in 1904. This artwork depicts a dramatic scene involving a sea nymph being rescued by a heroic figure, often incorporating themes of mythology, romance, and adventure. These kinds of works often evoke emotions related to heroism and the beauty of the sea.
As of my last update in October 2023, Sea Speed Ferries is not a widely recognized entity, and there may be limited information available. It is possible that it refers to a ferry service provider that operates passenger and/or vehicle ferries in a specific region. The name suggests a focus on speed and efficiency in maritime transportation. Ferry services typically provide essential transportation links between islands, coastal areas, or across bodies of water, and they may offer both scheduled services and charter options.
Rail transport images refer to photographs, illustrations, or artwork that depict various aspects of rail transportation. This can include images of trains, railways, stations, tracks, and related infrastructure. These images can showcase different types of trains (such as passenger or freight), various rail systems (such as electric or steam), and the landscapes that railways traverse. Rail transport images are often utilized for educational purposes, historical documentation, artistic expression, or promotional material for tourism and rail services.
The German Centre for Rail Traffic Research, known in German as "Deutsches Zentrum für Schienenverkehrsforschung" (DZSF), is a research institution focused on railway transportation. Established in 2019, the DZSF aims to advance knowledge and innovation in the field of rail traffic, enhancing safety, efficiency, and sustainability of rail systems.
Skateboarding is a recreational activity and sport that involves riding and performing tricks on a skateboard, which is a flat board mounted on four wheels. Skateboarding can be practiced in various environments, including streets, skateparks, and bowls. The basic components of a skateboard include the deck (the board itself), trucks (the components that hold the wheels), and wheels.
Lists of tunnels refer to organized collections or catalogs of tunnels located around the world, typically grouped by certain criteria, such as geography, purpose, or construction date. These lists may include various types of tunnels, such as: 1. **Transportation Tunnels**: Used for roads, railways, and subways (e.g., the Channel Tunnel, the Gotthard Base Tunnel). 2. **Hydraulic Tunnels**: Designed for water supply, drainage, or irrigation purposes (e.g.
In the context of art, "transport" typically refers to the ability of a work of art to evoke strong feelings, emotions, or thoughts in the viewer, effectively transporting them to a different place or time. This concept can be understood in various ways: 1. **Emotional Transport**: Art can elicit powerful emotional responses, allowing viewers to experience a range of feelings—joy, sadness, nostalgia—thus "transporting" them to a different emotional state.
Traffic management refers to the set of actions and strategies used to ensure the efficient movement of people and goods on roadways and transportation systems. It involves coordinating various elements of transportation to improve safety, reduce congestion, enhance mobility, and minimize environmental impact. Here are key components of traffic management: 1. **Traffic Control Devices**: These include traffic signals, signs, markings, and signals to direct and regulate road users.
"Junction types" can refer to different concepts depending on the context, such as network theory, transportation, or databases. Below are some interpretations based on different fields: 1. **Transportation and Traffic Engineering**: Junction types refer to designs or layouts of intersections where roads meet. Common junction types include: - **T-junction**: Where one road meets another at a perpendicular angle, forming a "T". - **Crossroads**: Where two roads cross each other.
Transport infrastructure typically refers to the various facilities, networks, and systems that support the movement of people and goods. These can include roads, bridges, railways, airports, ports, and other facilities essential for transportation. When discussing transport infrastructure "by year of completion," it usually means listing significant transport projects and their completion dates.
Vertical transport devices are equipment or systems designed to move people or goods vertically between different levels or floors of a building or structure.

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.
