77K. Low enough for "high temperature superconductors" such as yttrium barium copper oxide, but for "low temperature superconductors", you need to go much lower, typically with liquid helium, which is likely much more expensive. TODO by how much?
Where Do You Get Liquid Nitrogen? by The King of Random (2016)
Source. He just goes to a medical gases shop in a local industrial estate and buys 20L for 95 dollars and brings it back on his own Dewar marked 35LD.Making Liquid Nitrogen From Scratch! by Veritasium (2019)
Source. "From scratch" is perhaps a bit clickbaity, but I'll take it.Sophrosyne is a philosophical and ethical concept that originates from ancient Greek thought. It is often translated as "moderation," "temperance," or "self-control." The term encompasses the idea of embodying balance and harmony within oneself, particularly in relation to one's desires, emotions, and intellect. In classical philosophy, sophrosyne was highly valued, particularly by philosophers such as Socrates, Plato, and Aristotle.
The Communications Controller for Linux (CComm) is a software platform designed to facilitate communication between different devices and applications in a Linux environment. It typically includes a set of tools, libraries, and protocols that enable the management and control of communication interfaces, such as serial ports, network connections, and other data transfer technologies.
IBM LU6.2, also known as Advanced Program-to-Program Communication (APPC), is a protocol developed by IBM for communication between applications on different computers in a network. Specifically, LU6.2 is part of the Systems Network Architecture (SNA) that facilitates communication in a networked environment. Here are some key points about IBM LU6.2: 1. **APPC Protocol**: LU6.
RTÉ Aertel is an interactive teletext service provided by Raidió Teilifís Éireann (RTÉ), which is Ireland's national public service broadcaster. Launched in the early 1990s, Aertel offers a range of information including news, sports updates, weather forecasts, and program schedules directly accessible through television sets equipped with teletext capabilities.
NCR Century 100 refers to a point-of-sale (POS) system developed by NCR Corporation, which is a global leader in technology solutions. The Century 100 is part of NCR's portfolio of POS solutions designed for retail and hospitality environments. It typically features advanced technology for processing transactions, managing inventory, and integrating with other business systems.
Usenet spammers refer to individuals or automated systems that post unsolicited, irrelevant, or often advertising-driven content to Usenet newsgroups. Usenet is a distributed discussion system that predates modern web forums and social media, allowing users to post and share messages across various topics. Spamming in this context can involve: 1. **Mass Posting**: Sending the same message to multiple newsgroups to promote a product, service, or website, often irrelevant to the discussions in those groups.
"Data Toolbar" can refer to different tools or features in various software applications, but it generally relates to a user interface element that helps users manage, analyze, or visualize data more effectively. Here are some potential interpretations of "Data Toolbar" depending on the context: 1. **In Spreadsheet Applications (like Excel)**: A Data Toolbar may provide quick access to functions and features related to data manipulation, such as sorting, filtering, data validation, or creating charts.
A search engine cache refers to a stored version of a webpage that a search engine maintains in its database. When a search engine crawls the web, it collects information about various pages to index them efficiently. Instead of fetching the live content from the web every time a user performs a search, the search engine retrieves this cached version, which allows for improved speed and performance.
"Telemarketers" is a documentary series that premiered on HBO in 2023. The series is directed by Samir Reddy and revolves around the world of telemarketing, exploring the often unsettling and exploitative practices within the industry. It specifically follows the experiences of two telemarketers, highlighting their interactions and the morally ambiguous nature of their work.
Viscosity is a measure of a fluid's resistance to flow. It quantifies how thick or sticky a liquid is and is an important property in various fields, including physics, engineering, and fluid dynamics. There are two main types of viscosity: 1. **Dynamic Viscosity (Absolute Viscosity)**: This measures the internal resistance of a fluid to gradual deformation by shear stress or tensile stress.
"Lux" can refer to several different concepts depending on the context. Here are a few: 1. **Illumination/Light Measurement**: In scientific terms, "lux" is a unit of measurement for illuminance, which quantifies the amount of light that is received on a surface area. One lux is equal to one lumen per square meter. It is commonly used in fields related to lighting design and architecture.
Traditional French units of measurement refer to the system of measurement that was commonly used in France before the adoption of the metric system, which was introduced during the French Revolution in the late 18th century. The metric system was designed to standardize measurements and make them universally applicable. Here are some of the traditional French units of measurement: 1. **Length:** - **Pied**: A foot, approximately 0.33 meters.
United States customary units (USCS) refer to the system of measurement commonly used in the United States. This system is based on the Imperial system and includes various units for measuring length, area, volume, weight, and temperature. Below is an overview of some key units within the US customary system: ### Length - **Inch (in)**: 1 inch = 2.54 centimeters - **Foot (ft)**: 1 foot = 12 inches = 0.
A "ken" is a traditional unit of measurement that is commonly used in parts of East Asia. Specifically, in Japan, one ken is typically equivalent to about 1.82 meters (approximately 6 feet). It is often used in the context of measuring the dimensions of buildings, particularly in the context of traditional Japanese architecture, where rooms are often designed based on the number of kens.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
