The "List of minor planets: 75001–76000" refers to a specific segment of minor planets (or asteroids) that have been assigned numbers in the range of 75001 to 76000 by the International Astronomical Union (IAU). These numbers are part of a larger catalog of minor planets, which are small celestial bodies orbiting the Sun, primarily located in the asteroid belt between Mars and Jupiter.
A photometer is an instrument used to measure the intensity of light. It quantifies the amount of light that passes through or is emitted from a source, and it can be employed in various scientific and practical applications. Photometers can measure light in different contexts, such as luminous intensity (in terms of lumens), irradiance (in watts per square meter), or illuminance (in lux), depending on the specific type of photometer.
The Doomsday rule is a mental algorithm devised by mathematician John Horton Conway to determine the day of the week for any given date. The method works based on the concept of "Doomsday," which refers to a specific day of the week that certain dates within a year always fall on.
The list of minor planets from 93001 to 94000 refers to a catalog of minor planets (also known as asteroids) that have been assigned identification numbers within that specific range by the Minor Planet Center. Each minor planet is typically designated with a number based on the order in which it was discovered, along with a name if it has been officially named.
HAZUS (Hazards U.S.) is a standardized risk assessment tool developed by the Federal Emergency Management Agency (FEMA) to estimate the potential losses from various hazards, including earthquakes, floods, and hurricanes. It combines geographic information system (GIS) technology with data on buildings, infrastructure, and demographics to provide estimates of physical, economic, and social impacts from potential disasters.
The "List of named minor planets: R" includes minor planets (also known as asteroids) that have been assigned names starting with the letter "R." These minor planets are typically numbered when they are discovered, and as a result, they are often referred to by their number as well as their name. The list may include a variety of minor planets, ranging from those in the inner asteroid belt to those that are more distant.
A list of nuclear weapon explosion sites typically includes locations where nuclear tests have been conducted. These tests can be carried out by various countries, and the sites vary in number and significance. Here are some notable nuclear test sites from around the world: 1. **Nevada Test Site (USA)** - Located in the desert north of Las Vegas, it was the primary location for nuclear testing by the United States from 1951 until 1992.
The Soviet Union conducted a series of nuclear weapons tests from 1949 to 1990, which are often categorized and documented based on various factors such as year, type of weapon, and test location.
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is an international treaty that aims to ban all nuclear explosions for both civilian and military purposes. As of my last knowledge update in October 2023, the CTBT had been signed by 185 countries and ratified by 170 countries.
The projected death tolls from nuclear attacks on cities can vary widely based on numerous factors, such as the size of the bomb, the population density of the target area, the time of day the attack occurs, and the preparedness of the city and its emergency response systems.
A variety of scientific units are named after people to honor their contributions to science and technology. Here is a list of notable scientific units named after individuals: 1. **Ampere (A)** - The unit of electric current, named after André-Marie Ampère. 2. **Becquerel (Bq)** - The unit of radioactivity, named after Henri Becquerel.
As of my last update in October 2021, the list of South American countries by life expectancy can vary slightly depending on the source and the year of the data. However, I can provide a general ranking based on data from organizations like the World Bank and the World Health Organization (WHO) around that time. For the most accurate and up-to-date statistics, it's always best to refer directly to those organizations.
In Germany, statistical offices operate at both the federal and state levels. Here's a list of the primary statistical offices: ### Federal Level: 1. **Federal Statistical Office (Statistisches Bundesamt, Destatis)** - This is the main statistical office for Germany that collects, analyzes, and disseminates statistical information at the national level. ### State Level: Germany is divided into 16 federal states (Bundesländer), each with its own statistical office.
Here is a list of some of the largest cannons by caliber, notable for their size and historical significance: 1. **Dora and Gustav (Germany)** - These railway guns were built during World War II and had a caliber of 800 mm (31.5 inches). They were among the heaviest and largest artillery pieces ever constructed, specifically designed for long-range bombardment.
The list of Ukrainian mathematicians includes many notable figures who have made significant contributions to various fields of mathematics. Here are some prominent Ukrainian mathematicians: 1. **Grigori Perelman** - Known for his work on the Poincaré conjecture. 2. **Sofia Kovalevskaya** - One of the first women to earn a degree in mathematics and known for her work in analysis and differential equations. 3. **Mykhailo S.
The Variational Quantum Eigensolver (VQE) is a hybrid quantum-classical algorithm designed for finding the ground state energy of a quantum system, particularly useful in quantum chemistry and materials science. VQE combines the strengths of both quantum computing and classical optimization techniques to tackle problems that may be infeasible for classical computers alone.
The "List of unnumbered minor planets: 2000 ST" refers to a compilation of minor planets (also known as asteroids) that were discovered and named in the range designated by the prefixes beginning with the letters S and T in the year 2000. Minor planets are solid, celestial bodies that orbit the Sun and are typically smaller than a planet.
The "List of unnumbered minor planets: 2001 PR" refers to a catalog of minor planets (also known as asteroids) that were observed and designated with provisional names in the year 2001, specifically those that start with the letters P through R. Minor planets are typically designated by a provisional designation when they are discovered, which consists of the year of discovery followed by a letter (or letters) indicating their order of discovery within that year.
The "List of unnumbered minor planets: 2002 R (0–262)" refers to a collection of minor planets (or asteroids) that have been discovered and designated with provisional designations starting with "2002 R," but have not yet been assigned a permanent number by the International Astronomical Union (IAU).

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
