The Treaty of Tordesillas, signed on June 7, 1494, was an agreement between Portugal and Spain aimed at resolving disputes over newly discovered lands in the Americas and the exploration of the world. It was facilitated by the Pope, who sought to prevent conflict between the two major maritime powers of the era. The treaty established a meridian 370 leagues west of the Cape Verde Islands, officially dividing the newly discovered lands outside Europe between Spain and Portugal.
The **Journal of Geodynamics** is a scientific journal that focuses on research related to the dynamics of the Earth's interior and the processes involved in geophysical phenomena. This journal typically publishes original research articles, reviews, and technical notes that cover various aspects of geodynamics, including tectonics, seismology, mantle convection, plate tectonics, geophysical modeling, and related areas in earth sciences.
Plate theory, particularly in the context of volcanism, refers to the scientific understanding of how tectonic plates interact with one another and how those interactions influence volcanic activity. This theory is a fundamental component of the broader field of plate tectonics, which describes the movement of the Earth's lithosphere, the rigid outer layer of the Earth, broken into several large and small plates.
The number 2 is a numeral that represents a quantity or value. It is the natural number that follows 1 and precedes 3.

Ancient Greek units of measurement were varied and could differ between city-states, but several standard units were commonly used across the Greek world. Here are some of the notable units of measurement in Ancient Greece: ### Length: 1. **Cubit (Pous)**: Roughly equivalent to the length of a forearm, about 18 inches (46 cm). 2. **Foot (Pous)**: Approximately 12 inches (30.5 cm).
The term "Aṅgula" has multiple meanings depending on the context: 1. **Anatomical Reference**: In traditional Indian medicine and anatomy, "aṅgula" refers to a finger or a digit. It is often used in texts related to Ayurveda and traditional medical practices to denote measurements related to fingers or the distance that can be measured using the fingers.
A "batman" is a historical unit of measure for weight that was used primarily in British India. It is defined as equal to 100 seers. The batman is approximately equal to 3.6 kilograms or about 8 pounds, though the exact weight can vary slightly based on regional definitions and practices. The term "batman" originally comes from the Persian word "batman," meaning "a specific quantity of measurement.
The term "Biblical mile" is not a standard measurement in biblical texts; instead, it likely refers to a concept related to the measurements found in the Bible. In ancient times, distances were often measured using units like cubits, fathoms, and stadia, rather than modern units like miles. However, a "Biblical mile" can sometimes be interpreted as an approximate distance based on the historical and geographical context of the Bible.
Cullingey does not appear to refer to a well-known term, location, or concept based on the information available up until October 2023. It may be a misspelling or a lesser-known term.
Maltese units of measurement refer to the systems and units historically used in Malta, as well as modern metrics employed today. Historically, Malta's measurement system was influenced by various cultures due to its geographical location and history, including the Romans, Arabs, and the British. Some traditional Maltese units that were used include: 1. **Maltese Mile (Mial)**: An older unit of distance.
The Winchester measure refers to a historical system of measurement that was used in England, particularly in the city of Winchester, which was historically a major center of trade and commerce. The Winchester measure is primarily associated with the standard units of volume, weight, and linear measurement that were established during the medieval period. One of the key components of the Winchester measure is the "Winchester bushel," which was a unit of volume used for dry goods.
Orders of magnitude is a way to express the scale or size of a quantity in powers of 10. When discussing torque or any other physical quantity, the term helps to compare and understand differences in scale between various values. **Torque**, which is a measure of the rotational force applied to an object, is expressed in units such as newton-meters (Nm) or foot-pounds (ft-lb).
A centroid is a fundamental geometric concept referring to the arithmetic center of a shape or a set of points. In different contexts, the term can have specific meanings: 1. **In Geometry**: - The centroid of a simple shape, like a triangle or a polygon, is the point that represents the average position of all the points in the shape. It can be thought of as the center of mass if the shape has uniform density.
The "Gal" (short for galileo) is a unit of acceleration in the centimeter-gram-second (CGS) system, primarily used in the field of geophysics and other areas of physics to measure gravity or acceleration. One gal is defined as an acceleration of one centimeter per second squared (cm/s²). In terms of conversion, 1 Gal is equivalent to \(10^{-2}\) m/s².
The SOFAR channel, short for "Sound Fixing and Ranging" channel, is a horizontal layer of water in the ocean where sound speed reaches its minimum, creating a unique acoustic phenomenon. This channel typically forms at a depth of about 700 meters (or about 2,300 feet) in deep ocean waters, but its exact depth can vary based on factors such as temperature, salinity, and pressure.
Gravimetry is the measurement of the gravitational field strength of an object or the Earth itself. It involves the use of gravimeters, which are sensitive devices that detect variations in gravitational acceleration at different locations. The primary goal of gravimetry is to understand the distribution of mass within the Earth and other celestial bodies, which can provide valuable information about geological structures, subsurface features, and even the dynamics of Earth's atmosphere and oceans.
The Free-Air Gravity Anomaly (FAGA) is a geophysical measurement that represents the difference between the observed gravity and the gravity value that would be expected at a particular elevation above a reference surface, typically the Earth's mean sea level. This measurement helps to identify variations in the Earth's gravitational field that are not due to changes in elevation, such as those caused by geological structures.
Lucien LaCoste is a name associated with a brand of premium French wines, particularly known for producing high-quality wines from the Bordeaux region. It may also refer to the founder of a winery or vineyard that specializes in traditional winemaking methods, emphasizing terroir and unique flavor profiles.
Robot navigation refers to the process by which a robot determines its position and movement within an environment to reach a specific goal or perform tasks effectively. It involves several key components, including: 1. **Localization**: The robot's ability to identify its position relative to a map or environment. This can involve various techniques, such as GPS for outdoor navigation, or sensors like LIDAR, cameras, or ultrasonic sensors for indoor environments.

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.
