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.
The South Eastern European Dialogue on Internet Governance (SEEDIG) is a multi-stakeholder initiative aimed at fostering dialogue and collaboration on internet governance issues in Southeast Europe. Launched in 2015, SEEDIG serves as a platform for various stakeholders, including governments, civil society organizations, academia, technical communities, and the private sector, to discuss and address internet-related challenges and opportunities specific to the region.
Varignon's theorem, also known as the Varignon's law of moments, is an important principle in the field of mechanics, particularly in the study of static equilibrium of forces. The theorem states that if a system of forces acts on a particle and we take the moment about any point, the total moment about that point can be determined by considering the moments of the individual forces about that point.
Copal is a type of natural resin that is typically derived from the trees in the family Burseraceae, which includes species such as the Frankincense and Myrrh trees. Copal has been used for various purposes throughout history, including in traditional medicine, incense, and as a binding agent in varnishes and paints. There are several types of copal, distinguished by factors such as the tree species they come from, their age, and their collection methods.
Metrication is the process of converting a system of measurement to the metric system, which is based on the International System of Units (SI). The metric system uses units such as meters for length, grams for mass, and liters for volume, and it is designed to be decimal-based and easy to use. Countries that undertake metrication typically adopt the metric system for various applications, including education, science, industry, and everyday life, with the goal of standardizing measurements for clarity and efficiency.
Several computer companies were disestablished in 1952, primarily as the industry was still in its early stages and underwent significant changes. One notable example is the **UNIVAC Division of Sperry Rand**. While UNIVAC itself did not completely shut down, the division underwent changes that eventually led to its integration into other companies or its transformation as technologies advanced.
State-sponsored internet propaganda refers to the use of online platforms and digital media by government entities or organizations backed by the state to promote specific political agendas, shape public perception, or influence public opinion. This form of propaganda can take various forms, including: 1. **Disinformation campaigns**: Deliberately spreading false or misleading information to influence public opinion or disrupt social cohesion.
Mean Signed Deviation (MSD) is a statistical measure that quantifies the average of the signed differences between observed values and a central measure, such as the mean or median. Unlike the Mean Absolute Deviation (MAD), which takes the absolute values of the deviations to avoid cancellation, the Mean Signed Deviation retains the positive and negative signs of the differences.
The Deep Space Atomic Clock (DSAC) is a space-based atomic clock developed by NASA to improve the precision and reliability of timekeeping for spacecraft navigation and communication in deep space missions. Its main purpose is to enhance the accuracy of navigational data used when exploring distant parts of the solar system.
Maritime pilotage is a specialized service provided by maritime pilots who assist in navigating ships through challenging waterways, such as harbors, rivers, and coastal areas. These pilots are experts in local maritime conditions, including currents, tides, and navigational hazards. Their primary role is to ensure the safety of vessels as they approach or depart from ports, as well as maneuver through narrow or congested areas.
In geometry, "orientation" refers to the arrangement or positioning of a geometric object in relation to a coordinate system or to other objects. It can describe how the object is aligned or how its vertices or edges are ordered. Here are a few contexts in which orientation is commonly discussed: 1. **In 2D Geometry**: In the context of two-dimensional shapes, orientation often relates to the direction in which a shape is drawn or traversed.
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.
