A Troll doll, also known as a Dam doll or Troll, is a plastic toy with a distinctive design that features an oversized head, colorful hair, and a small body. These dolls were originally created by Danish woodcutter Thomas Dam in the late 1950s and quickly gained popularity in the United States during the 1960s and 1990s. Troll dolls typically have a whimsical appearance, with wide-set eyes and a goofy smile.
Victorian mourning dolls were figurines or dolls created during the Victorian era (1837-1901) in England, often made as part of the mourning rituals associated with the death of a loved one. This period had unique customs surrounding death and grief, and mourning dolls represented a way for mourners to memorialize the deceased. These dolls were often made to resemble the deceased or to symbolize someone who had passed away.
Ambiguity resolution refers to the process of clarifying and determining the intended meaning or interpretation of ambiguous information, language, or situations. Ambiguity can arise in various contexts, including natural language processing, linguistics, communication, mathematical expressions, and even in decision-making scenarios. 1. **In Natural Language Processing (NLP)**: Ambiguity resolution involves disambiguating words, sentences, or phrases that can have multiple meanings based on their context.
"Discoveries" is a book by Eugene Merle Shoemaker, a renowned American geologist and planetary scientist, known for his pioneering work in the fields of impact cratering and planetary geology. The book, published in 1997, provides insight into Shoemaker's research and contributions to our understanding of planetary bodies, including the moon and Mars.
A highly powerful number is defined as a positive integer \( n \) such that for every prime \( p \) that divides \( n \), \( p^2 \) also divides \( n \). In other words, in the prime factorization of a highly powerful number, each prime factor appears with an exponent of at least 2.

Paul H. Carr is a physicist known for his contributions to the field, particularly in areas related to applied physics and engineering. His work has had implications in various domains, including materials science and the development of technologies. However, specific details about his research, notable theories, or publications may require access to scientific literature or databases.
The Differential Doppler Effect refers to the variation in the frequency (or wavelength) of waves emitted by a source that is moving relative to an observer, when there are multiple sources or multiple observers involved. This effect is particularly significant in scenarios where there are changes in velocity or direction between different sources or observers. The basic concept of the Doppler Effect describes how the observed frequency changes in relation to the relative motion between a source of waves (such as sound or light) and an observer.
Doppler cooling is a technique used in atomic and molecular physics to reduce the temperature of a sample, typically of atoms or ions, by using the principles of the Doppler effect. It is particularly effective for cooling atoms to very low temperatures, near the absolute zero threshold, which allows for the study of quantum phenomena and precision measurements. The technique relies on the interaction between laser light and atoms.
Paul Horowitz is a prominent figure known primarily for his contributions in the field of electrical engineering and physics. He is a professor at Harvard University and has been involved in various research areas, including electronics, photonics, and the development of innovative technologies. Additionally, he is well-known for co-authoring the textbook "The Art of Electronics," which is highly regarded in the academic and engineering communities for its practical approach to circuit design and electronics.
Doppler radio direction finding is a technique used to determine the direction of a radio frequency transmission source by analyzing the Doppler effect on the received signal. The Doppler effect refers to the change in frequency or wavelength of a wave in relation to an observer moving relative to the source of the waves. In the context of radio direction finding, this effect is used to ascertain the location of a transmitter.
Ayşe Şahin could refer to various individuals, as it is a common name in Turkey. Without specific context, it’s challenging to determine who you are referring to. It could be a public figure, artist, academic, or someone else notable.

Pradip Baijal is known in India primarily as a former bureaucrat and public servant. He has held various significant positions in the Indian government and has contributed to policy-making in sectors such as telecommunications and information technology. Baijal served as the Chairman of the Telecom Regulatory Authority of India (TRAI) from 2003 to 2006, a period during which he played a key role in shaping the telecom landscape of the country.
"Ramesh Chandra" could refer to several individuals, as it is a common name in India and other South Asian countries. Without additional context, it's challenging to determine which specific Ramesh Chandra you are referring to. 1. **Ramesh Chandra in Academia**: There may be scholars or researchers by that name who have made contributions in various fields. 2. **Ramesh Chandra in Politics**: There could be politicians or public figures known by that name.
Reliance Communications (RCOM) was a telecommunications company based in India, founded in 2004 and a part of the larger Reliance Group, which is owned by billionaire Mukesh Ambani. RCOM provided a variety of telecommunications services, including mobile voice and data services, broadband, and enterprise solutions. The company was known for its extensive network infrastructure and coverage across India. Reliance Communications was one of the early entrants in the Indian telecom market and played a significant role in India's telecom boom.
Sadiq Batcha is not a widely recognized figure or term in popular culture or global news as of my last update in October 2023. It is possible that Sadiq Batcha refers to a specific individual, event, organization, or concept that has emerged or become relevant after that date, or it may be a term that is not widely documented.

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.
