A conjecture is an educated guess or a proposition that is put forward based on limited evidence, which has not yet been proven or disproven. In mathematics and science, conjectures arise from observations or patterns that suggest a certain conclusion, but they need formal proof or experimental validation to be accepted as a theorem or law.
The Inverse Galois Problem is a central question in the field of algebra, particularly in the area of field theory and algebraic geometry. It seeks to determine whether every finite group can be represented as the Galois group of some field extension of the rational numbers \(\mathbb{Q}\) or more generally, of some base field.
Hermite's problem, named after the French mathematician Charles Hermite, refers to an important question in the theory of numbers that concerns the representation of numbers as sums of squares. Specifically, the problem seeks to establish conditions under which a natural number can be expressed as a sum of squares of integers. One of the notable results related to Hermite's problem is a theorem concerning the number of ways a given positive integer can be expressed as a sum of two squares.
A Kármán vortex street is a recurring pattern of swirling vortices caused by the unsteady separation of flow of a fluid around a bluff body (an object with a large cross-section, such as a cylinder). This phenomenon was first described by Hungarian-American engineer Theodore von Kármán in the 1910s. When a fluid flows past a blunt object, such as a cylinder or a flat plate, it can create alternating low-pressure and high-pressure areas in the flow.
A longitudinal wave is a type of wave in which the particles of the medium through which the wave travels vibrate in the same direction as the wave's propagation. In other words, the displacement of the medium's particles is parallel to the direction of the wave's energy transfer. This is in contrast to transverse waves, where the displacement of the medium's particles is perpendicular to the direction of the wave's travel. A common example of a longitudinal wave is a sound wave.
Weather events refer to specific atmospheric occurrences that can range from everyday phenomena to extreme conditions. These events can affect local, regional, or even global climates and include a variety of occurrences. Some common categories of weather events include: 1. **Precipitation**: Rain, snow, sleet, and hail, which occur when moisture in the atmosphere condenses and falls to the ground.
LinuxChix is an online community that was created to support women in the Linux and open source technology fields.

The community provides resources, forums, mailing lists, and other opportunities for networking and mentorship, enabling women to learn about Linux, contribute to open source projects, and share their experiences in the tech industry.
John Cantius is a name associated with a Roman Catholic church, known formally as St. John Cantius Church, located in Chicago, Illinois. The church is renowned for its traditional liturgical practices and has a reputation for promoting the classical form of the Roman Rite. St. John Cantius Church is named after St. John Cantius, a 15th-century Polish priest and scholar known for his devotion to education and the Catholic faith.
Paul of Middelburg (also known as Paulus de Middelburg) was a Dutch philosopher, theologian, and humanist who lived during the Renaissance period. Born around 1480 in Middelburg, he is often recognized for his contributions to the fields of philosophy, theology, and the study of arts and sciences. He was notably a proponent of the humanist movement and was involved in the theological debates of his time.
Joachim Sterck van Ringelbergh (also spelled as Ringelberch) was a notable figure from the 16th century, primarily known as a Dutch poet and humanist. He was born in 1544 and became associated with the court of William of Orange during a time of significant political and religious turmoil in the Netherlands.
Matrakçı Nasuh (1480-1564) was an influential Ottoman Turkish architect, historian, and miniaturist, renowned for his contributions to the fields of cartography and military architecture. He is perhaps best known for his detailed maps and illustrations, which played a significant role in the documentation and understanding of the Ottoman Empire and its geographical territories during the 16th century.
Evangelista Torricelli (1608–1647) was an Italian physicist and mathematician, best known for his work in fluid dynamics and for his invention of the barometer. He is often credited with the discovery of the principle of atmospheric pressure. One of his significant contributions to science is the Torricelli’s law, which describes the speed of fluid flowing out of an orifice under the influence of gravity.
Christian Ludwig is a physicist known for his work in the field of condensed matter physics, particularly related to the study of complex materials and nanostructures. His research often involves exploring the electronic and magnetic properties of materials at the nanoscale, which can have applications in various technologies including electronics, information storage, and energy systems.
Canonical units, in a general context, refer to a standardized set of units used for measurement in various fields such as physics, engineering, and mathematics. These units provide a consistent framework for expressing quantities in a way that is widely recognized and accepted. In physics, for example, canonical units often align with the International System of Units (SI), which defines the fundamental units (meter, kilogram, second, etc.) and derived units (such as joules for energy, or newtons for force).
Giovanni Battista Venturi (1746-1822) was an Italian physicist and engineer, best known for his work in fluid dynamics and for the development of the Venturi effect. The Venturi effect describes the phenomenon where a fluid's velocity increases as it passes through a constricted section of a pipe, which leads to a drop in pressure. This principle has practical applications in various fields, including hydraulics, aerodynamics, and engineering design.
In computing, the term "1924" does not have a specific or recognized meaning directly associated with the field. However, there are contexts in which the number might come up, such as in historical discussions, standards, or protocols. If you are referring to a specific context, such as an operating system version, a standard in computing (like IEEE 802.1 for networking), a computer model, or other technical specifications, please provide more details.
Emacs is a highly customizable and extensible text editor that is widely used for programming, writing, and many other text manipulation tasks. It was originally created in the 1970s by Richard Stallman and has since evolved into a powerful tool supported by a large community of users and developers. Key features of Emacs include: 1. **Extensibility**: Emacs is built around a Lisp interpreter, allowing users to write their own extensions and customize the editor to suit their specific needs.
In computing, "1999" can refer to a couple of significant events and contexts: 1. **Y2K Problem**: The year 1999 is famously associated with the anticipation of the Year 2000 problem, commonly known as the Y2K bug. As the year approached, there was widespread concern that many computer systems would fail or produce errors when the year rolled over from 1999 to 2000.
The year 1985 was significant in the computing world for several reasons, marking important developments in hardware, software, and technologies that would shape the future of computing. Here are some of the key events and trends from that year: 1. **Introduction of Windows 1.0**: Microsoft released Windows 1.0 on November 20, 1985.

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.
