The Henry George theorem is a concept in public finance and urban economics, named after the American economist Henry George. The theorem addresses the relationship between land values, public infrastructure investments, and the benefits received from those investments by property owners. In essence, the Henry George theorem posits that the increase in land value resulting from public investments (such as the construction of roads, parks, schools, and other public facilities) can be captured through taxation.
Outwelling is an ecological process that occurs primarily in coastal and estuarine environments, where nutrients and organic matter are exported from coastal wetlands, such as salt marshes and mangroves, into adjacent aquatic systems, like estuaries and oceans. This process is essential for maintaining the productivity and health of marine ecosystems. Outwelling typically involves the movement of decomposed organic material, nutrients (like nitrogen and phosphorus), and detritus from the wetland habitat into the water column.
Econometricians are professionals who specialize in econometrics, which is a branch of economics that applies statistical and mathematical methods to analyze economic data. Their work involves developing models that help understand and quantify relationships among economic variables, testing hypotheses, and forecasting future trends. Econometricians employ various techniques, including regression analysis, time-series analysis, and panel data analysis, to extract meaningful insights from complex data sets.
The Fundamental Theorems of Welfare Economics consist of two key results that connect the allocation of resources in a market economy with the concepts of efficiency and optimality. These theorems provide a theoretical foundation for understanding how competitive markets operate and under what conditions they lead to socially desirable outcomes.
Intensity of preference refers to the strength or degree of an individual's preference for one option over another. It is a concept often used in economics, psychology, and decision-making studies to understand how much more someone prefers one choice compared to alternatives. For example, if a person prefers chocolate ice cream over vanilla ice cream, the intensity of that preference can vary.
Debreu's representation theorems refer to results in mathematical economics developed by Gérard Debreu, particularly concerning the representation of preferences, utility functions, and their relation to general equilibrium theory.
Weller's theorem, particularly in the context of number theory, is a result related to the distribution of prime numbers in certain arithmetic progressions. It essentially provides a criterion for determining when a prime number will be found in a given arithmetic sequence.
The transport industry encompasses all businesses and activities involved in the movement of goods and people from one location to another. This industry is a critical component of the global economy, facilitating trade, commerce, and travel. It includes various modes of transportation, each with its own characteristics, benefits, and limitations. The main categories of the transport industry include: 1. **Road Transportation**: This includes vehicles such as cars, trucks, buses, and motorcycles.
TRESOR (short for "Trésor," which means "treasure" in French) refers to several concepts, but in a contemporary context, it is often associated with: 1. **TRESOR Cryptocurrency Wallet**: A hardware wallet that allows users to store their cryptocurrency securely offline. Trezor was one of the first hardware wallets on the market and is widely used by crypto holders for enhancing security against hacking.
Mahmud Ahmad Hamdi al-Falaki is not a widely recognized historical figure or contemporary individual based on the information available up to October 2021. It is possible that the name refers to a specific person in a niche context or a local figure not covered in major historical or contemporary accounts.
Abdel-Moniem El-Ganayni is known for his contributions to the field of finance and investment, particularly in the context of Arab economies. However, there may not be widely recognized specific information about him in public sources.
Euler's critical load refers to the maximum buckling load that a slender column can withstand before it deforms elastically due to compression. The concept is derived from Euler's formula, which expresses the critical load \( P_{cr} \) depending on the column's material properties and geometric characteristics.
Hypoelastic materials are a type of material model used in continuum mechanics to describe the behavior of materials that exhibit a nonlinear elastic response. The term "hypoelastic" refers to materials that do not have a predefined elastic potential energy function and do not necessarily exhibit a linear relationship between stress and strain.
Johnson's parabolic formula is an empirical relationship used to describe the shape of a parabolic trajectory in the context of projectile motion. Specifically, it is often used to model the range of a projectile as a function of launch angle and initial velocity. The formula provides an approximation that is useful for engineering applications and helps predict the behavior of projectiles under ideal conditions, neglecting air resistance.
Lamé's stress ellipsoid is a conceptual representation used in the field of continuum mechanics to visualize the state of stress at a specific point within a material body. It is named after the French engineer and mathematician Gabriel Lamé. The stress ellipsoid provides a way to understand the distribution of normal and shear stresses acting on a point in three-dimensional space.
Mohr's Circle is a graphical representation used in the field of mechanics and civil engineering to analyze the state of stress at a point in a material. It provides a way to visualize the relationships between normal and shear stresses acting on various planes through that point, making it easier to understand complex stress states.
Shear modulus, also known as the modulus of rigidity, is a measure of a material's ability to resist shear deformation when a shear force is applied. It quantifies how much a material will deform under shear stress, which is a force that causes layers of the material to slide past each other.
The tangent modulus, also known as the tangent stiffness modulus, is a measure used in the field of material science and engineering to describe the relationship between stress and strain in a material, particularly beyond the linear elastic region of the stress-strain curve. It is defined as the slope of the tangent line to the stress-strain curve at a given point, representing the material's stiffness at that specific level of strain.
The International Statistical Institute (ISI) is a professional organization that promotes the understanding, development, and application of statistical methods and practices globally.

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.
