Egyptian astronomy refers to the astronomical knowledge and practices developed by the ancient Egyptians. This field of study was integral to their culture, influencing various aspects of their society, including religion, agriculture, and architecture. Here are some key components of Egyptian astronomy: 1. **Celestial Observations**: Ancient Egyptians carefully observed the night sky and the movements of celestial bodies, including stars, planets, the Sun, and the Moon. They recognized the importance of these cycles for timekeeping and agriculture.
The term "Fifth Planet" often refers to a hypothetical planet that could have existed in our solar system between Mars and Jupiter. This concept is primarily related to theories about the early solar system's formation and the dynamics of planetary bodies. In the mid-20th century, astrophysicists proposed that early in the solar system's history, there may have been a fifth terrestrial planet that was disrupted or ejected due to gravitational interactions with the other planets, particularly Jupiter.

Ancient Greek epistemologists were philosophers who explored the nature, origins, and limits of knowledge. Their inquiries into knowledge laid the foundations for Western philosophy and significantly influenced later thoughts in metaphysics, ethics, and science. Some prominent figures in ancient Greek epistemology include: 1. **Socrates (c.
In ancient Greek epistemology, concepts played a crucial role in understanding how knowledge is acquired, categorized, and utilized. The ancient Greeks, particularly philosophers like Plato and Aristotle, grappled with the nature of concepts and their relation to knowledge and reality. 1. **Plato's Theory of Forms**: Plato posited that concepts (or Forms) are the eternal and unchanging ideals that represent the true essence of things.
"Gods in the Sky" is a title that could refer to various things, such as a book, film, song, or other creative works. Without additional context, it's hard to determine the exact reference you are looking for.
"Handy Tables" typically refers to compact, easy-to-use reference tables or charts that summarize important information, calculations, or data for quick access. These tables can cover a wide range of subjects, including mathematics, science, engineering, and statistics, among others. Some common features of handy tables include: 1. **Mathematical Constants**: Values for pi, e, and other important mathematical constants. 2. **Conversions**: Common unit conversions (e.g., metric to imperial).
Intihuatana is a significant archaeological site located near the town of Ollantaytambo in the Urubamba Valley, Peru. The name "Intihuatana" translates to "the place where the sun is tied" in Quechua, and it refers to a ritual stone used by the Incas.

It supposedly existed around 9,000 years before his time and sank into the ocean.
The Maya calendar is a system of calendars used by the ancient Maya civilization, which flourished in Mesoamerica, particularly in areas like present-day Mexico, Guatemala, Belize, Honduras, and El Salvador. The Maya developed a sophisticated understanding of astronomy and timekeeping, leading to the creation of multiple calendar systems that were used for various purposes, including agriculture, religious rituals, and historical record-keeping.
Mursili's eclipse refers to an ancient astronomical event documented in Hittite texts, specifically concerning King Mursili II of the Hittite Empire, who reigned around the 14th century BCE. The significance of this event lies in its potential correlation with historical solar eclipses, allowing researchers to study and pinpoint dates in Hittite chronology. The texts describe a solar eclipse that occurred in relation to a military campaign led by Mursili II.

Smart materials and structures refer to materials and systems that have the ability to sense, respond to, and adapt to environmental changes or external stimuli in a controlled manner. These materials can change their properties or behavior in response to factors such as temperature, pressure, electric or magnetic fields, humidity, and mechanical forces. The field encompasses a wide range of technologies and applications, often integrating aspects of materials science, engineering, and electronics.
"Somnium Scipionis," or "The Dream of Scipio," is a work attributed to the Roman philosopher and statesman Cicero. It is part of his broader work "De Republica" (On the Republic), and it takes the form of a philosophical dialogue.

He is most often known for his contributions to geometry and for his work in the field of mathematics, particularly in the study of solid figures and the theory of irrational numbers. Theaetetus is often credited with the mathematical formulation of types of numbers, including the classification of numbers into rational and irrational.
Xenagoras was an ancient Greek geometer, known primarily for his work on geometry. He lived around the 4th century BCE and is sometimes associated with students or followers of Plato. His contributions are not as extensively documented as those of other prominent mathematicians, and much of what is known about him comes from later references.
Attalus of Rhodes, also known as Attalus the philosopher, was a notable figure in ancient philosophy, particularly associated with the Stoic school. He lived during the 2nd century BC and was known for his works and teachings that contributed to Stoic thought.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
