Crazing refers to the formation of fine cracks or fissures on the surface of a material, typically seen in ceramics, glass, or certain plastics. These cracks can appear as a network of tiny lines, giving the surface a "crazy" or cracked appearance. Crazing can occur due to various factors, including: 1. **Thermal Stress**: Rapid temperature changes can cause expansion and contraction in materials, leading to stress and eventual cracking.
Satkaryavada is a philosophical concept found in Indian philosophy, particularly within the Samkhya and Mimamsa schools. The term can be broken down into two parts: "Sat," meaning "that which is" or "truth," and "Karya," meaning "effect" or "action." Thus, Satkaryavada can be translated as the doctrine of the "effect being pre-existing in the cause.
A self-defeating prophecy is a prediction or expectation that, instead of coming true, contributes to its own failure or negation. This concept is often discussed in psychology and social sciences as it illustrates how beliefs and expectations can influence behaviors and outcomes. For instance, if a student believes they will fail an exam, they may not study adequately or approach their preparation with confidence, which increases the likelihood of poor performance, ultimately fulfilling their original expectation of failure.
The Two-State Vector Formalism (TSVF) is a conceptual framework in quantum mechanics proposed by physicist Yakir Aharonov and his collaborators. It extends traditional quantum mechanics by introducing the idea that a quantum system can be described not only by a state vector evolving forward in time but also by a state vector that evolves backward in time.
The Spice Girls dolls are a line of figurines that were created based on the popular British girl group, the Spice Girls, who rose to fame in the 1990s.

He is known for his work in the field of mathematics and for his contributions to the development of computational methods. Although he is not as widely recognized as his father, Benjamin Herschel Babbage made significant contributions in his own right, including in the area of mathematics education and the advancement of mathematical science during his time.
Carrier generation and recombination are fundamental processes that occur in semiconductor materials and play a vital role in determining their electrical properties. Here's a breakdown of both processes: ### Carrier Generation Carrier generation refers to the creation of charge carriers (electrons and holes) in a semiconductor. This can occur through a variety of mechanisms: 1. **Thermal Generation**: At absolute zero, a semiconductor has no free charge carriers.
As of my last knowledge update in October 2023, "Deathnium" does not refer to any widely recognized scientific term, element, or concept. It might be a fictional element, a term from a specific book, game, or a new concept that has emerged since then.

MSKCC is renowned for its dedication to cancer research, prevention, diagnosis, treatment, and education, and it is consistently ranked among the best cancer hospitals in the United States.
An ionophore is a chemical compound that facilitates the transport of ions across a lipid membrane. This can occur by forming a complex with the ion, allowing it to dissolve in the membrane or by creating a channel that allows the ion to pass through. Ionophores are commonly used in biological and biochemical research to study ion transport and to manipulate the ionic composition of cells.
"Charles Babbage: Pioneer of the Computer" is a title that often refers to the life and contributions of Charles Babbage, an English mathematician, philosopher, inventor, and mechanical engineer, who is best known for his work on early computers. Babbage is often referred to as the "father of the computer" for his concept of a programmable computer. Babbage designed several mechanical calculating machines, the most notable being the Difference Engine and the Analytical Engine.

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.
