The Oxford mathematics Moodle has detailed course listings, and most PDFs are not paywalled.
E.g. the 2024 course:
"Photonics and Nanostructures: Fundamentals and Applications" is likely a reference to a book or academic resource that explores the field of photonics, particularly focusing on the role of nanostructures in various applications. **Photonics** is the science and technology of generating, manipulating, and detecting photons, particularly in the visible and near-infrared spectrum.
"...Smile's OK" is a phrase that refers to a specific type of welcoming or friendly expression, though without more context, its exact meaning might vary.
iBeacon is a technology developed by Apple that enables Bluetooth Low Energy (BLE) devices to send signals to nearby smartphones and tablets. It utilizes a protocol that allows these devices to communicate with each other in an efficient and low-energy manner. The iBeacon system consists of small hardware devices called beacons that emit a unique identifier at regular intervals.
The number 5 is a natural number that follows 4 and precedes 6. It is an integer, an odd number, and is often used in various contexts such as counting, mathematics, and everyday life. In mathematics, 5 is considered a prime number because it is greater than 1 and has no positive divisors other than 1 and itself. Additionally, it can represent different things in various scenarios, like a rating (e.g.
Aliasing is a phenomenon that occurs in various fields, such as signal processing, computer graphics, and audio processing, when a signal is sampled or represented in a way that leads to misrepresentation or distortion of the original information. 1. **Signal Processing**: In the context of digital signal processing, aliasing occurs when a continuous signal is sampled at a rate that is insufficient to capture its full range of frequencies.
Math Blaster Jr. is an educational video game designed to help young children develop foundational math skills in a fun and engaging way. It is part of the larger Math Blaster series, which is aimed at teaching various math concepts to different age groups. In Math Blaster Jr., players typically engage in various activities and mini-games that focus on basic math skills such as counting, addition, subtraction, and problem-solving.
"Discoveries" is a work by Hermann Goldschmidt, a notable German-born painter and writer who later became a resident of France. Goldschmidt is perhaps best known for his contributions to the art world in the 19th century, particularly through his focus on natural history and the documentation of scientific discoveries.
In the context of Unix and Unix-like operating systems, `crypt` typically refers to a function or utility used for encryption and decryption of data, particularly passwords. It is part of the Unix password management system for securely storing and verifying user passwords. Historically, the `crypt` function was included in the C library and used a simple form of encryption called DES (Data Encryption Standard).
"Progress in Polymer Science" is a scientific journal that publishes comprehensive and critical reviews covering various aspects of polymer science and engineering. The journal showcases advancements in polymer chemistry, physics, materials science, and related interdisciplinary fields. It typically features in-depth articles that summarize recent developments, new methodologies, and emerging trends in polymer research. The articles in "Progress in Polymer Science" are often authored by leading experts in the field, providing insights into topics such as polymer synthesis, characterization, properties, and applications.
Alexander Golubov is a prominent physicist known for his contributions to condensed matter physics, particularly in the field of superconductivity and spintronics. His work often involves theoretical studies related to the properties of materials at the nanoscale, magnetic materials, and their interactions with superconductors.
"Discoveries" by Holger Thiele refers to a project or initiative led by this author, but there isn't a widely recognized work titled "Discoveries" by Holger Thiele up to my last knowledge update in October 2023. Holger Thiele could be a researcher, author, or figure in a specific field, potentially related to discoveries in science, technology, or another area, but further context would be needed to provide a more specific answer.

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
