"Inter caetera" is a papal bull issued by Pope Alexander VI on May 4, 1493. The document was significant in the context of European colonial expansion in the Americas. It served to legitimize the territorial claims of Spain and Portugal in the New World following Christopher Columbus's voyages. The bull essentially divided the newly discovered lands outside Europe between Spain and Portugal.
Washington Meridians is a term that can refer to two different concepts in the context of geography and surveying, but it is primarily associated with the geographic coordinate system used in mapping and surveying in the United States, especially in relation to the land management practices of the General Land Office (GLO). 1. **Geographic Meridians**: In general geography, meridians are the lines of longitude that run from the North Pole to the South Pole.
The general and ideal user acquisition is of course organic Googling:
However, before that point, it is very likely that Ciro will have to physically do some very hard and specific user acquisition work at some University. Maybe there is a more virtual way of achieving this.
This work will involve going through some open set of university lecture notes, and creating a superior version of them on OurBigBook.com, and somehow getting students to notice it and use it as a superior alternative to their crappy lecture notes.
Another very promising route is publishing the answers to old examination questions on the website. It is likely that we will be able to overcome any copyright issues by uploading only the answers to numbered questions. There is a minor risk that these would be considered derivative works of the copyrighted questions. But universities would have to be very anal to enforce a DMCA for that!!!
Getting in contact with students is an epic challenge, as an incredibly deep chasm separates us:
Walking with advertisement t-shirts mentioning specific course names in some university location is something Ciro seriously considers, that's how desperate things are. Watch out: docs.ourbigbook.com/#public-relations for T-shirt news!
Intraplate volcanism refers to volcanic activity that occurs within a tectonic plate, away from plate boundaries. Unlike the more commonly recognized volcanism associated with divergent or convergent plate boundaries, which involves processes like subduction or rifting, intraplate volcanism happens in the interior regions of tectonic plates.
Long-period tides refer to tidal oscillations that occur over longer time frames compared to the more typical diurnal (daily) or semidiurnal (twice daily) tides. Specifically, long-period tides are classified as having periods of greater than one day, usually 24 hours or more, and they manifest as variations in the sea level that are influenced primarily by gravitational interactions between the Earth, Moon, and Sun.
"Old Drift" and "Young Drift" are terms used in geology and geomorphology, particularly in the context of discussing river valleys and sediment deposition. 1. **Old Drift**: This term generally refers to older sediment deposits that have settled in a river valley over a longer geological time frame. These sediments are often more compacted and may have undergone significant weathering and soil development. They can contain fossilized remains and are typically associated with earlier stages of a river's history.
Location awareness refers to the ability of a device, application, or system to determine and utilize the geographical location of an individual or object. This technology can integrate data from various sources, such as GPS, Wi-Fi, cell towers, and sensors, to ascertain positioning and enable context-aware services. Key aspects of location awareness include: 1. **Geolocation**: The process of identifying the real-world geographical location of an object, often using GPS or other positioning technologies.
A tracking system is a technology or methodology designed to monitor and record the movement or status of objects, assets, or individuals over time. Tracking systems can be applied in various contexts, and they typically involve hardware, software, and communication technologies to capture and analyze data. Here are some common types of tracking systems: 1. **GPS Tracking Systems**: These use Global Positioning System (GPS) technology to determine and track the location of vehicles, assets, or people in real-time.
"Arş" is a term that has different meanings depending on the context in which it is used: 1. **Islamic Context**: In Islamic theology, "Arş" (Arabic: عرش‎) refers to the Throne of Allah. It is considered one of the highest and most significant creations of God, representing His majesty and authority. The concept of the Arş is often mentioned in the Quran and Islamic literature, symbolizing divine power and control over the universe.
The term "candy" can refer to a variety of sweet confections, but in the context of units, it typically refers to a unit used in the game "Candy Crush" or other similar mobile games. In these games, "candy" is often the primary collectible or resource that players gather and use to progress through levels or unlock features.
A decimal is a numerical system that represents fractions as an extension of the base-10 (or decimal) number system. In a decimal representation, numbers are expressed using digits 0 through 9, and the position of each digit indicates its value based on powers of ten. For example, in the decimal number 123.
A "Homer" is a non-SI unit of measurement used humorously to quantify the amount of beer. It is popularly attributed to Homer Simpson, a fictional character from the animated television show "The Simpsons," known for his love of beer. One Homer is often humorously defined as a "large quantity of beer," and in some contexts is said to be equivalent to approximately 12 barrels of beer, which is around 372 gallons or 1,409 liters.
The Macedonian cubit is an ancient unit of measurement, specifically a length measurement used in the historical region of Macedonia. The term "cubit" generally refers to a measurement that is based on the length of the forearm from the elbow to the tip of the middle finger. Different cultures and regions had their own definitions of the cubit, leading to variations in the actual length.
"On Weights and Measures" typically refers to a historical text or treatise concerning the standards and systems of measurement. One of the most notable works related to this topic is by the ancient Greek philosopher and mathematician Euclid, who wrote about geometric principles and measurements in his work "Elements." However, in a more modern context, "On Weights and Measures" can refer to various legislative acts or guidelines that establish standards for weights and measures, ensuring consistency in trade and commerce.
A "palm" is a unit of measurement used to define the width of the human hand. Specifically, a palm is commonly regarded as being equivalent to 3 inches (about 7.62 centimeters). This unit has historical roots and was often used in various fields, including carpentry and tailoring, before the adoption of more standardized measurements. It is also sometimes used in contexts like horse racing to describe the height of horses (though this is less common).
"Wey" is a unit of measurement that refers to a unit of coal. It is not a widely used unit today but historically has been associated with quantifying quantities of coal for trade and transport. The term is particularly relevant in the context of certain regions or systems that may have specific local definitions and values associated with this unit.
Orders of magnitude refer to the scale or range of values often expressed in powers of ten. In the context of specific heat capacity, this means categorizing materials based on how much energy they require to change their temperature by a certain amount. Specific heat capacity is defined as the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius (or one Kelvin). Different materials have different specific heat capacities, which can vary significantly, often across several orders of magnitude.
The truncated mean is a measure of central tendency that is calculated by removing a specified percentage of the highest and lowest values from a data set before computing the mean. This technique is useful for reducing the influence of outliers or extreme values that could skew the mean. To calculate the truncated mean: 1. **Order the Data**: Arrange the data points from smallest to largest.

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.
