Josef Čapek (1887–1945) was a Czech painter, graphic artist, and writer, best known for his contributions to modern art and literature. He was the brother of the famous writer Karel Čapek, who is known for his works in science fiction and for coining the term "robot." Josef Čapek was involved in various artistic fields, including painting, illustration, and design.
"A Man of Misconceptions" is a historical novel written by Jon Steele, published in 2013. The book tells the story of the life and adventures of the 17th-century Englishman, the astronomer, and mathematician Thomas Harriot, who was a contemporary of Galileo and Kepler. Harriot is portrayed as a man ahead of his time, grappling with the scientific and cultural limitations of his era.
The Dannie Heineman Prize for Astrophysics is an award established to recognize outstanding achievements in the field of astrophysics. It is jointly sponsored by the American Institute of Physics and the American Astronomical Society. The prize is awarded annually to individuals who have made significant contributions to the field, and it often honors achievements in specific areas such as observational or theoretical astrophysics. The winners of this prestigious prize typically include leading scientists who have advanced our understanding of the universe through research and innovation.
The Lepton epoch is a specific phase in the early universe, occurring shortly after the Big Bang. It is characterized by the dominance of leptons—fundamental particles that include electrons and their neutrinos, as well as their heavier counterparts like muons and taus. The Lepton epoch begins roughly 10^-6 seconds after the Big Bang and lasts until about 1 second after the Big Bang.
Password strength refers to how difficult it is for an unauthorized party to guess or crack a password. A strong password is essential for protecting personal and sensitive information from cyber threats, such as hacking and unauthorized access. Several factors contribute to password strength, including: 1. **Length**: Longer passwords are generally stronger. A good rule of thumb is to use at least 12 to 16 characters.
Prince is a lightweight block cipher that was designed for high performance in constrained environments, such as IoT devices and smart cards. It was introduced in 2012 by its creators, who wanted to provide a secure and efficient encryption solution. The cipher uses a structure known as a "substitution-permutation network" and operates on blocks of data.
Biological carbon fixation is the process by which carbon dioxide (CO2) is converted into organic compounds by living organisms, primarily through the process of photosynthesis. This process is crucial for maintaining the Earth's carbon cycle and is foundational for the production of food and energy in ecosystems. In photosynthesis, plants, algae, and certain bacteria utilize sunlight to convert CO2 and water into glucose and oxygen.
A diffusion tube is a passive sampling device used to measure the concentration of certain gases or pollutants in the atmosphere, particularly in air quality monitoring. These tubes are typically made of a plastic or glass casing filled with a specific absorbent material or chemical that reacts with the target gas. ### Key Features of Diffusion Tubes: 1. **Passive Sampling**: Diffusion tubes work without the need for pumps or electrical components.
Proof of Stake (PoS) is a consensus mechanism used by blockchain networks to validate transactions and add new blocks to the blockchain. Unlike Proof of Work (PoW), which requires miners to solve complex mathematical problems to validate transactions, PoS selects validators based on the number of coins they hold and are willing to "stake" as collateral.
Protocol Composition Logic (PCL) is a formal framework used to reason about the security properties of cryptographic protocols, particularly in the context of how different protocols can be composed together. The fundamental idea behind PCL is to assess how the security of individual protocols interacts when they are used together, which is crucial in real-world applications where multiple protocols often run concurrently or in conjunction with each other.
A secure channel refers to a communication pathway that is established to ensure the confidentiality, integrity, and authenticity of the information exchanged between parties. It employs various security measures, including encryption, authentication, and integrity checks, to protect the data from eavesdropping, tampering, and impersonation.
James J. Kay is a noted figure in the field of systems thinking and systems design. He is particularly known for his work on the development of the "systems-oriented design" approach, which emphasizes the importance of understanding the complex interrelationships within systems and includes aspects of ecological design and sustainability. Kay has also contributed to various academic publications and has been involved in community-based projects that focus on sustainability and ecological restoration.
In the context of electrical grids, "contingency" refers to an unexpected event or failure that disrupts the normal operation of the grid. This could involve the loss of a major power generator, transmission line, transformer, or other critical components that support the electricity supply and distribution system. Contingency analysis is an essential part of grid planning and operation.
Short Weather Cipher is a type of simple substitution cipher used historically for encoding messages in a way that could be easily transmitted over radio or written in brief forms. It was particularly popular in maritime and military communications where brevity and clarity were essential. In this cipher, code words or short phrases are used to represent specific weather conditions, orders, or other standard messages. For example, a particular code might represent "heavy rain," while another might indicate "clear skies.
Amedeo Odoni is known for his contributions to the field of operations research and aerospace engineering, particularly in air transportation systems and airport operations. He has been involved in various research efforts aimed at improving the efficiency of air transportation networks and airport management. His work often focuses on the optimization of air traffic flow, airport capacity, and the design of air traffic control systems.
Robert Edward Bell might refer to different individuals depending on the context, as there may be multiple people with that name. However, one notable Robert Edward Bell is a professor in the field of electrical engineering and computer science, known for contributions in areas such as telecommunications and signal processing.
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.

Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
