A bracket polynomial is a type of polynomial that arises in the study of knot theory, particularly in the context of the Kauffman bracket. The bracket polynomial is a quantum invariant of knots and links, providing a way to distinguish between different knot types.
Biomimetics, also known as biomimicry or bioinspiration, is a field of study that seeks to emulate or draw inspiration from nature’s designs, processes, and systems to solve human challenges. It involves observing the structures, functions, and strategies found in biological organisms and ecosystems and translating those insights into innovative technologies and solutions. The goal of biomimetics is to create sustainable and efficient designs, often in areas such as materials science, engineering, robotics, medicine, and architecture.
The 19th century in New Zealand was a period marked by the emergence of the country's scientific community, including contributions from physicists, though the field was still developing. Key developments in physics during this time were often influenced by broader scientific and technological advancements happening around the world. One notable figure was Sir George Everest, who, while primarily a land surveyor and geographer, made contributions related to geodesy and the accurate measurement of land in New Zealand.
The 19th century saw significant advancements in the field of physics, but it was also a time when women faced considerable barriers to education and participation in the sciences. Despite this, several women made noteworthy contributions to physics and related fields during this period.
Margrete Heiberg Bose is not a widely known figure in publicly available texts or resources as of my last update in October 2023. It's possible that she may be a private individual or a local figure not covered in major news or academic publications.
Alexandre Lazarian is a prominent astrophysicist known for his work in the field of astrophysical sciences, particularly related to interstellar medium, cosmic dust, and the dynamics of astrophysical processes. He has contributed to various areas including studies of magnetic fields in space, star formation, and the behavior of plasma in cosmic environments. His research often incorporates advanced simulations and theoretical models to explore and explain complex astrophysical phenomena.
"Hudong Chen" does not refer to a widely recognized concept, person, or entity within my training data up to October 2023. It might be a specific name, organization, or term that has emerged more recently, or it could be a lesser-known reference.
"Manuel Valadares" could refer to different entities, individuals, or contexts. Without more specific information, it's hard to pinpoint exactly what you're asking about. It might be a person's name, perhaps a historical figure, artist, or someone relevant in a specific field.

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.

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