The San Andreas Fault Observatory at Depth (SAFOD) is a scientific research facility established to study the San Andreas Fault, which is one of the most well-known and active tectonic boundaries in California. It was designed to investigate the processes occurring along the fault at great depths and to improve our understanding of fault mechanics, earthquake processes, and seismic hazards.
Oceanic crust is the part of Earth's lithosphere that underlies the oceans. It is primarily composed of basalt, a dense volcanic rock, and is generally thinner and younger than its continental counterpart. Key characteristics of oceanic crust include: 1. **Thickness**: Oceanic crust typically ranges from about 5 to 10 kilometers (3 to 6 miles) thick, making it thinner than continental crust, which can exceed 30 kilometers (19 miles) in thickness.
The Mohorovičić discontinuity, often referred to as the "Moho," is a significant geological boundary that marks the transition between the Earth's crust and the underlying mantle. It is named after the Croatian seismologist Andrija Mohorovičić, who discovered this boundary in 1909. The Moho is typically characterized by a sudden increase in the speed of seismic waves, indicating a change in composition and physical state.
The lower oceanic crust is a layer of the Earth's crust that forms part of the oceanic lithosphere. It is typically situated beneath the upper oceanic crust and lies above the mantle. The oceanic crust has a distinct layered structure, which can generally be divided into three main layers: 1. **Layer 1**: This is the sedimentary layer, consisting mainly of sediments that have settled on the ocean floor, including clay, silt, and biogenic materials like shells.
A low-velocity zone (LVZ) is a specific region within the Earth's interior, typically found in the upper mantle, characterized by a significant reduction in seismic wave velocities compared to surrounding areas. These zones are often associated with certain geological and tectonic features, such as subduction zones, hotspots, and the presence of partially melted rock.
The Lehmann discontinuity is a boundary within the Earth's interior that separates the outer core from the inner core. It is named after the German geophysicist Ernst Lehmann, who identified this transition in the early 20th century. The outer core is composed of molten iron and other elements, making it liquid, while the inner core is solid and consists primarily of iron and nickel.
The Kola Superdeep Borehole is a scientific drilling project located on the Kola Peninsula in Russia. Initiated in 1970 by the Soviet Union, the project aimed to explore the Earth's crust and reach deeper into the geological layers than ever before. The borehole reached its maximum depth of 12,262 meters (40,230 feet) in 1989, making it the deepest artificial point on Earth.
The K-U ratio is a financial metric used to evaluate the performance of a company's stock by comparing its earnings potential to its market capitalization. The "K" represents the company's earnings before interest and taxes (EBIT), and the "U" generally refers to the company's market capitalization.
Iron-nickel alloys are metallic materials composed primarily of iron and nickel, with varying proportions of each metal. These alloys are notable for their unique properties that make them useful in various applications. Some common types of iron-nickel alloys include: 1. **Invar**: This is a low-expansion alloy containing about 36% nickel and 64% iron.
Irina Artemieva is a scientist known for her work in the field of geophysics and geosciences. She has contributed to the understanding of the Earth's structure, dynamics, and processes through her research, often focusing on topics such as tectonics, earthquake mechanics, and geodynamic modeling.
The International Continental Scientific Drilling Program (ICDP) is an international initiative aimed at promoting scientific drilling into the Earth's continental crust. Established in the late 1990s, the ICDP seeks to facilitate research in various fields such as geology, paleontology, environmental science, and tectonics by providing access to deep continental geological formations.
**Statistics** is a branch of mathematics that deals with collecting, analyzing, interpreting, presenting, and organizing data. It provides a framework for making conclusions and informed decisions based on data. Statistics is used across various fields, including business, healthcare, social sciences, agriculture, and more. The primary objectives of statistics can be summarized as follows: 1. **Data Collection**: Acquiring relevant data through surveys, experiments, or observational studies.
Statistics in biosciences refers to the application of statistical methods and principles to analyze, interpret, and present data related to biological and health-related phenomena. This field is crucial for the design and evaluation of experiments, clinical trials, epidemiological studies, and observational research in areas such as medicine, genetics, ecology, and environmental science. Key aspects of statistics in biosciences include: 1. **Experimental Design**: Properly designing experiments to test hypotheses while controlling for variables that may influence results.
The Journal of Statistics Education (JSE) is a peer-reviewed academic journal that focuses on the teaching and learning of statistics. It aims to provide a forum for the exchange of ideas, research findings, and practical applications related to statistics education at all levels, from K-12 to higher education. The journal publishes articles that cover a wide range of topics, including but not limited to statistical literacy, curriculum development, teaching strategies, assessment, and innovative uses of technology in statistics education.
Diastereomeric recrystallization is a technique used in organic chemistry to separate diastereomers, which are types of stereoisomers. Unlike enantiomers, which are non-superimposable mirror images of each other and have identical physical properties except for their interactions with plane-polarized light, diastereomers have different physical properties due to their non-mirror-image relationships.
Dynamic stereochemistry refers to the study of stereochemical aspects of molecules that are in constant motion or undergoing rapid conformational changes. Unlike traditional stereochemistry, which often focuses on static conformations and fixed spatial arrangements of atoms in molecules, dynamic stereochemistry examines how these arrangements can change over time due to factors like heat, solvent interactions, or reactions.
Eclipsed conformation refers to a specific arrangement of atoms or groups in a molecule, particularly in the context of rotational conformations around a single bond. In an eclipsed conformation, the groups or atoms attached to the carbon atoms involved in the bond are positioned directly in front of each other when viewed along the axis of that bond. This contrasts with the staggered conformation, where the atoms or groups are positioned such that they alternate and minimize steric interactions.
The Journal of the American Statistical Association (JASA) is a leading scientific journal published by the American Statistical Association. It focuses on the dissemination of research and developments in statistical methodology, applications, and theory. Established in 1888, JASA covers a wide range of topics within statistics, including but not limited to: 1. **Statistical Theory**: Papers that contribute to statistical methods, inferential processes, and theory development.
The Journal of the Royal Statistical Society (JRSS) is a prestigious academic journal published by the Royal Statistical Society (RSS) in the United Kingdom. It is divided into several series, with the most prominent being: 1. **Series A: Statistics in Society** - This series focuses on the application of statistical methods to social science and public policy, exploring how statistical analysis can inform societal decisions.

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.
