It allows educators to write questions in a plain text format that can be easily imported into various systems. ### Aiken Code Format The Aiken format typically follows this structure: 1. **Question text**: The question itself is written on a single line.
Evolution in a variable environment refers to the concept that the conditions and challenges faced by organisms can change over time, influencing the process of natural selection and evolutionary adaptations. In such environments, organisms must be able to adapt not only to the current conditions but also to potential future changes in their habitat. Key aspects of evolution in a variable environment include: 1. **Phenotypic Plasticity**: This is the ability of an organism to alter its physical or behavioral traits in response to changes in the environment.
In Riemannian geometry, the exponential map is a crucial concept that connects the local geometric properties of a Riemannian manifold to its global structure. Specifically, it describes how to move along geodesics (the generalization of straight lines to curved spaces) starting from a given point on the manifold.
The term "export of cryptography" refers to the regulations and laws governing the international sale, transfer, or distribution of cryptographic software and hardware. Cryptography is the practice and study of techniques for securing communication and data, and it plays a crucial role in ensuring the confidentiality, integrity, and authenticity of information.
Size-exclusion chromatography (SEC), also known as gel filtration chromatography, is a separation technique used in biochemistry and analytical chemistry to separate molecules based on their size and shape. In this method, a porous gel or resin is used as the stationary phase, allowing smaller molecules to diffuse into the pores while larger molecules are excluded from entering them. This difference allows for the separation of components in a mixture as they pass through the column.
The Fama-French three-factor model is an asset pricing model that enhances the Capital Asset Pricing Model (CAPM) by adding two factors to account for the observed anomalies in stock returns that CAPM could not explain. Developed by Eugene Fama and Kenneth French in the early 1990s, the model aims to provide a better insight into the determinants of expected stock returns.

It is possible that he may be a private individual, or he may have gained prominence after that date. If you provide more context or specify the area in which Felix Iversen is relevant (e.g., sports, academia, etc.
Gödel's incompleteness theorems, formulated by the mathematician Kurt Gödel in the early 20th century, are two fundamental results in mathematical logic and philosophy of mathematics. They reveal inherent limitations in the ability of formal systems to prove all truths about arithmetic.
Gorre & Daphetid is a fictional location in the role-playing game "Dungeons & Dragons" (D&D) and is part of the larger campaign setting known as the "World of Greyhawk." It is a unique geographical area characterized by its dark and mysterious atmosphere, often associated with themes of horror and the supernatural. In Gorre & Daphetid, players typically encounter a range of challenges and adventures, including encounters with various monsters, magical phenomena, and opportunities for exploration.
GPS drawing, also known as GPS art or GPS mapping, is a creative practice that involves using a GPS device or smartphone to create images, patterns, or designs by moving through physical space. As individuals or groups walk, run, or bike along specific routes, their movements are tracked by GPS technology, which records the coordinates to create a visual representation of the route taken.
Graduate Texts in Mathematics (GTM) is a series of advanced mathematics textbooks published by Springer. The series is designed primarily for graduate students and advanced undergraduates, covering a wide range of topics in pure and applied mathematics.

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.
