Giovanni Girolamo Saccheri (1667–1733) was an Italian mathematician and philosopher, best known for his work in the field of non-Euclidean geometry. He is often considered one of the pioneers of this field due to his efforts to explore the implications of assuming alternatives to Euclid's parallel postulate, which is a foundational element of Euclidean geometry.
Dark current refers to the small amount of electric current that flows through a photodetector (such as a photodiode or a CCD—charge-coupled device) even when no photons are incident on the device. This current is a result of thermally generated charge carriers and can occur in various types of detectors.
Prohairesis is a term derived from ancient Greek philosophy, particularly associated with the works of Aristotle. It refers to a concept of moral choice or decision-making, distinguishing it from mere impulse or desire. In essence, prohairesis encompasses the rational, deliberative aspect of choosing one's actions based on values, reason, and ethical considerations. In Aristotle's ethical framework, prohairesis is crucial for understanding virtue and moral responsibility.
Data analysis is the process of systematically applying statistical and logical techniques to describe, summarize, and evaluate data. It involves inspecting, cleansing, transforming, and modeling data with the aim of discovering useful information, supporting decision-making, and drawing conclusions. Data analysis can be applied in various fields such as business, science, social science, and healthcare, among others.

Logical expressions are expressions that evaluate to a boolean value, which can be either true or false. In programming, mathematics, and philosophy, logical expressions are used to make decisions, perform operations, and evaluate conditions. ### Components of Logical Expressions: 1. **Operands:** The variables or values being evaluated. For example, in the expression `A AND B`, `A` and `B` are operands. 2. **Operators:** The symbols that represent logical operations.
Truth is a multifaceted concept that has been explored in various fields, including philosophy, science, religion, and everyday life. Generally, it refers to the quality or state of being in accord with fact or reality. Here are a few perspectives on truth: 1. **Philosophical Perspective**: In philosophy, truth is often debated in terms of various theories: - **Correspondence Theory**: Truth is what corresponds to reality or facts.
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.
