The strip packing problem is a classic optimization problem in the field of combinatorial optimization and computational geometry. The problem involves packing a set of items (usually rectangles) into a larger rectangular container, termed a "strip," with the objective of minimizing the height of the strip that is used. ### Problem Definition: 1. **Items**: You have a collection of rectangular items, each defined by its width and height.

The Mark I detector, also known as the Mark I at the Fermilab National Accelerator Laboratory, was one of the first particle detectors designed for use in high-energy physics experiments. It was primarily used in the 1970s and played a significant role in experimental particle physics during its operational period.
The Saskatchewan Accelerator Laboratory (SAL) is a research facility located at the University of Saskatchewan in Saskatoon, Canada. It is primarily focused on conducting nuclear physics research and offers various resources for academic, industry, and government projects. The laboratory features a particle accelerator and is used for a wide range of experiments in areas such as nuclear physics, medical physics, and materials science.
The Synchro-Cyclotron is a type of particle accelerator that was developed to accelerate charged particles, such as protons or ions, to high energies using principles of both synchrotron and cyclotron acceleration. While it is less commonly referenced in modern contexts, the Synchro-Cyclotron played an important role in the history of particle physics and accelerator technology. **Key Features of a Synchro-Cyclotron:** 1.
A quadrupole ion trap is a type of mass spectrometry device used to trap and analyze ions based on their mass-to-charge ratio. It utilizes an electric field generated by four rod electrodes arranged in a quadrupole configuration to confine ions in a three-dimensional space. Here's how it works: ### Structure: 1. **Four Rods**: The quadrupole ion trap consists of four parallel rods.
Alfred Jarry (1873–1907) was a French writer, playwright, and avant-garde artist best known for his play "Ubu Roi" (1896), which is considered a precursor to the absurdist and surrealist movements in theater. This play features the character Père Ubu, a grotesque figure who embodies greed and tyrannical behavior, and it is marked by its subversion of traditional theatrical conventions and its use of absurdity.
John Bryce McLeod does not appear to be a widely recognized figure or concept as of my last knowledge update in October 2023. It’s possible that he is a less prominent individual or a private citizen not widely documented in public sources. If you have a specific context in which you're inquiring about John Bryce McLeod—such as a particular field (arts, sciences, sports, etc.), event, or location—it might help narrow down the search. Please provide more details!
As of my last update in October 2023, I do not have specific information on an individual named Thomas Kappeler. It's possible that he may not be a widely recognized public figure or that he is known in a specific field or context that hasn't been documented extensively. If he is a contemporary figure, it might be worth checking the latest news sources or databases for the most current information.
Raúl Chávez Sarmiento is not a widely recognized figure in mainstream media or historical texts. It's possible that he could be a local figure, a professional in a specific field, or a fictional character.
"People in rail transport" generally refers to the individuals involved in various aspects of the rail industry, encompassing a wide range of roles and responsibilities. This can include: 1. **Railway Workers**: This group comprises a variety of job roles, including engineers, conductors, station staff, maintenance crews, and signaling personnel who directly operate the trains and maintain the infrastructure.
The concept of a "system of imprimitivity" comes from the field of group theory and is often used in the study of group actions. In the context of group actions on sets, a system of imprimitivity is a partition of a set that is invariant under the action of a group.
Liquid crystals are a state of matter that have properties between those of conventional liquids and solid crystals. In a solid crystal, the molecules are arranged in an ordered structure, while in a conventional liquid, they are disordered and free to move around. Liquid crystals, however, exhibit a unique combination of both order and fluidity.
Paracrystallinity refers to a structural characteristic of materials, particularly in the context of disordered solids, where the material exhibits some degree of periodic order but lacks the long-range order typically found in perfect crystals. In paracrystalline materials, there may be short-range order similar to that of crystalline structures, but this order diminishes over longer distances.
Ludwig Klages (1872–1956) was a German philosopher, psychologist, and a leading figure in the field of expressive and body psychology. He is known for his work on the relationship between spirit and body, as well as his critique of modernity and rationalism. Klages argued for a more holistic understanding of human existence, emphasizing the importance of emotions, instincts, and the unconscious.
George Bealer is an American philosopher known for his work in the philosophy of mind, metaphysics, and epistemology. He is particularly noted for his contributions to the discussion of realism, the nature of concepts, and the philosophy of mathematics. Bealer is also known for advocating a form of epistemic realism, which claims that abstract entities, such as numbers and mathematical objects, exist independently of our knowledge of them.
Ravi Gomatam is a notable figure in the field of philosophy, particularly known for his work in the areas of epistemology and metaphysics. He often engages in discussions surrounding the foundations of knowledge, the nature of reality, and the implications of various philosophical theories. His contributions can be found in academic settings, publications, and conferences, where he explores complex philosophical questions and encourages dialogue on critical issues.
William Crathorn was an English botanist and a key figure in the field of herbal medicine during the 16th century. He is perhaps best known for his work on plant classification and his writings on the medicinal properties of various herbs. One of his notable contributions is his book "The Whetstone of Witte," published in 1540, which includes information on the uses of plants for healing and other purposes.

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.
