A fiducial marker is a reference point or object used in various fields, including computer vision, robotics, biomedical imaging, and augmented reality, to provide a known position or orientation. These markers help in precise measurement, alignment, and tracking. Fiducial markers typically have distinct patterns or shapes that can be easily recognized by cameras or sensors. Common examples include: 1. **Circular or square markers**: These might have a specific black-and-white pattern or QR code.
WUHU is a software application designed to display and log data from weather stations, particularly those utilizing the Davis Vantage Pro and Vantage Vue systems. The software is particularly popular among amateur meteorologists and hobbyists who want to monitor local weather conditions. WUHU allows users to interface with their weather stations to collect and visualize a variety of meteorological data, including temperature, humidity, barometric pressure, wind speed and direction, rainfall, and more.
As of my last update in October 2023, there is no widely recognized public figure, concept, or entity known as "Rely Zlatarovic." It’s possible that this name refers to a private individual, a lesser-known personality, or a misspelling of another name.
Meteorology, the scientific study of the atmosphere and its phenomena, has evolved significantly over the centuries. Here's a brief overview of its development by century: ### Ancient Times to 17th Century - **Ancient Civilizations**: Early weather observations were made by ancient cultures (e.g., Mesopotamians, Greeks, and Chinese). They noted seasonal patterns and tried to predict weather for agricultural purposes.
Marine larval ecology is the study of the life stages of marine organisms that occur after fertilization and before reaching a juvenile or adult stage. This field focuses on the development, distribution, behavior, and interactions of larvae in the marine environment. Marine larvae can include a wide variety of organisms, such as fish, invertebrates (like mollusks and crustaceans), and coral, each with unique larval characteristics and ecological roles.
An ionosonde is a type of radar used to examine the ionosphere, which is a region of the Earth's upper atmosphere (approximately 30 miles to 600 miles above the surface) that is ionized by solar and cosmic radiation. The ionosphere plays a crucial role in radio wave propagation, affecting communication and navigation systems.
Wolf-Rayet nebulae are a type of astronomical object associated with Wolf-Rayet stars, which are massive stars in a late stage of stellar evolution. These stars are characterized by their strong stellar winds, high temperatures, and distinct spectral lines, particularly of heavy elements such as carbon, nitrogen, and oxygen. When a Wolf-Rayet star evolves and sheds a significant portion of its outer layers through powerful stellar winds, it creates an expansive nebula composed of gas and dust.
The Taiji Program, also known as the Taiji Initiative or Taiji Project, is a Chinese space mission focused on gravitational wave detection. Named after the concept of "Taiji," which refers to a philosophical and martial arts concept of balance, the program aims to develop and launch a space-based gravitational wave observatory.
Nanofluids are engineered colloidal suspensions of nanoparticles in conventional heat transfer fluids, such as water, ethylene glycol, or oil. When nanoparticles, typically ranging from 1 to 100 nanometers in size, are dispersed in these fluids, they can significantly enhance the thermal conductivity and heat transfer characteristics compared to the base fluid alone.
Finite Element Updating (FEU) is a methodology used in structural analysis, particularly in the context of dynamic systems and model validation. It involves the revision of a finite element model based on experimental or field data to improve the accuracy of the model's predictions. This process typically includes: 1. **Model Validation**: The initial finite element model is created based on theoretical principles and design parameters.
Nuclear energy in England, as part of the broader UK energy landscape, refers to the use of nuclear fission to generate electricity. The UK has a well-established nuclear power program with several operational nuclear power plants that provide a significant portion of the country's electricity. ### Key Points on Nuclear Energy in England: 1. **History**: The UK was one of the first countries to develop nuclear power, with its first commercial power station, Calder Hall, opening in 1956.
Uranium mining is the process of extracting uranium ore from the ground, which is then used mainly for fuel in nuclear power plants and for certain military applications. The major uranium-producing countries differ in terms of production volume, mining methods, and regulatory environments. Here is a brief overview of some of the leading countries involved in uranium mining, based on information up to October 2023: ### 1.
Nuclear accidents and incidents refer to unexpected events related to nuclear power plants, nuclear reactors, or other facilities that handle radioactive materials, which result in the release of radiation or the potential for radiation exposure to the public and the environment. These events can range from minor safety breaches to catastrophic meltdowns. They can be caused by various factors, including human error, equipment failure, natural disasters, or terrorist actions. **Key Types of Nuclear Accidents and Incidents:** 1.
The list of nuclear and radiation accidents by death toll includes several high-profile incidents, each varying in terms of the number of fatalities caused, either directly from the event or through long-term health effects. Here are some of the most significant nuclear and radiation accidents categorized by their estimated death toll: 1. **Chernobyl Disaster (1986, Ukraine)** - The Chernobyl nuclear power plant disaster is widely regarded as the worst nuclear accident in history.
The McCloy–Zorin Accords refer to an agreement that was reached in 1961 during the Cold War, specifically related to the ban on nuclear weapons testing. Named after U.S. negotiator John McCloy and Soviet negotiator Andrei Zorin, these accords were part of a broader effort to limit nuclear weapons proliferation and reduce the risk of nuclear conflict. The accords aimed to establish a framework for future negotiations on a comprehensive nuclear test ban treaty.
"The Hidden Reality" is a popular science book written by physicist Brian Greene, published in 2011. In this book, Greene explores the concept of multiverses and presents various theories that suggest the existence of multiple universes beyond our own. He examines different models from physics and cosmology, including string theory, the many-worlds interpretation of quantum mechanics, and theories of parallel universes.
"Stars in My Pocket Like Grains of Sand" is a science fiction novel by Samuel R. Delany, first published in 1984. The novel is known for its complex narrative structure, rich world-building, and exploration of themes including sexuality, language, identity, and the nature of communication. The story is set in a far-future universe and follows the character Marq Dye, a human from a distant planet who becomes involved with the inhabitants of another world.
Crankstart Foundation by Ciro Santilli 37 Updated 2025-07-16
At crankstart.org/grants the organization's website describes mostly California activities, but they do at least also act in the University of Oxford, see: Section "University of Oxford study costs".
Presumably the name refers to crank starting an old car, as in helping out those in difficulty like poor students get started in life. But is also an obscure slang for a type of handjob according to Urban Dictionary.

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.
