Holism is a philosophical and conceptual approach that emphasizes the importance of understanding systems and phenomena as a whole rather than merely as a collection of parts. The term comes from the Greek word "holos," meaning "whole" or "entire." Holism suggests that the properties and behaviors of a system cannot be fully understood by examining its individual components in isolation; instead, the interactions and relationships between those components contribute significantly to the system's overall functionality and characteristics.
Mean Glandular Dose (MGD) is a calculated value that represents the average radiation dose received by the glandular tissue of the breast during mammography. It is an important metric in radiology, particularly in breast imaging, as it helps to assess and monitor the potential risks of radiation exposure associated with mammography procedures. The MGD takes into account various factors, including: 1. **Radiation Exposure**: The amount of x-ray radiation used during the mammographic procedure.
Climatologists are scientists who study climate, which is the long-term pattern and average of weather conditions in a specific area over extended periods, typically decades to millions of years. Their work encompasses understanding the Earth's climate systems, including factors that influence climate such as atmospheric conditions, ocean currents, solar radiation, and human activities. Climatologists analyze various data, including temperature records, precipitation patterns, and atmospheric composition, to identify trends and make predictions about future climate changes.
A passive dual coil resonator is a type of resonant circuit that comprises two inductive coils (or inductors) arranged in a specific configuration to create resonance at a particular frequency.

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.
