Marine parks are designated areas in oceans or coastal waters that are established to protect marine ecosystems and biodiversity. These parks are similar to national parks on land, as they aim to conserve wildlife habitats and provide a safe environment for various marine species. Marine parks can include a variety of ecosystems, such as coral reefs, mangroves, seagrass beds, and open ocean areas.
The Arabian Basin, also known as the Arabian Sea Basin, is a geological and oceanographic feature located in the northwestern part of the Indian Ocean. It includes the waters of the Arabian Sea and stretches from the southwestern coast of India to the eastern coasts of the Arabian Peninsula and northeastern Africa. The basin is characterized by its unique geological properties, tectonic interactions, and oceanographic conditions.
The New York Marine Rescue Center (NYMRC) is a non-profit organization dedicated to the rescue, rehabilitation, and conservation of marine mammals and sea turtles in New York waters. Established to address the needs of injured, stranded, or sick marine wildlife, the center provides medical care and rehabilitation to these animals, aiming to release them back into their natural habitats whenever possible.
Deep-sea wood refers to organic matter, particularly submerged wood, found in deep-sea environments, such as ocean floors, canyons, and other abyssal regions. This wood typically comes from trees that have fallen into rivers or coastal areas and eventually made their way into the ocean.
"Oceanography" is a scientific journal that focuses on the field of ocean sciences. It publishes articles and research findings related to various aspects of oceanographic research, including physical oceanography, chemical oceanography, biological oceanography, and marine geology. The journal aims to foster a greater understanding of ocean processes and their impact on the Earth’s environment and climate.
A conservative force is a type of force in physics that has the property that the work done by the force on an object moving from one point to another is independent of the path taken between the points. Instead, the work done depends only on the initial and final positions of the object. This means that if the object returns to its original position, the total work done by a conservative force over that closed path is zero.
Consilience is a term that refers to the principle of unity of knowledge, suggesting that evidence from independent, unrelated sources can converge to support a particular conclusion or theory. The concept was popularized by the biologist E.O. Wilson in his 1998 book "Consilience: The Unity of Knowledge." In this work, Wilson argues for the integration of information from different fields such as science, humanities, and social sciences to foster a more comprehensive understanding of complex issues.
Underdetermination refers to a situation in philosophy of science and epistemology where the available evidence is insufficient to uniquely determine which of several competing theories or explanations is the correct one. In other words, multiple hypotheses can explain the same set of observations or data, leading to the conclusion that the evidence does not definitively support one theory over another.

lspci by Ciro Santilli 40 Updated 2025-07-16
lspci is the name of several versions of CLI tools used in UNIX-like systems to query information about PCI devices in the system.
On Ubuntu 23.10, it is provided by the pciutils package, which is so dominant that when we say "lspci" without qualitication, that's what we mean.
Psychoanalytic infant observation is a method used primarily in psychoanalytic training and research that involves the systematic observation of infants in their natural environments, usually conducted over a period of time. This method is deeply rooted in psychoanalytic theory and is focused on understanding the emotional and developmental processes of infants through careful and detailed observation.

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 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
