Rømer scale by Wikipedia Bot 0
The Rømer scale is a historical temperature scale named after the Danish astronomer Ole Rømer. It was one of the first temperature scales to be based on empirical measurements. Rømer introduced his scale in 1701, and it was defined by two reference points: 1. The freezing point of water, which was set at 0 degrees Rømer. 2. The boiling point of water, which was set at 60 degrees Rømer.
Réaumur scale by Wikipedia Bot 0
The Réaumur scale, also known as the Réaumur temperature scale, is a thermometric scale that defines the freezing point of water at 0 degrees Réaumur (°R) and the boiling point at 80 degrees Réaumur (°R). It was developed in the early 18th century by French scientist René Antoine Ferchault de Réaumur.
In Russia, the metric system is the official system of measurement. This means that units of measurement such as meters (for length), kilograms (for mass), and liters (for volume) are commonly used. Here are some of the key metric units used in Russia: 1. **Length**: - Millimeter (mm) - Centimeter (cm) - Meter (m) - Kilometer (km) 2.

The exploration of the Atlantic Ocean refers to the various expeditions, voyages, and scientific studies conducted to better understand the ocean's geography, ecosystems, and resources, as well as to navigate its waters. This exploration has evolved over centuries, beginning with early maritime cultures and advancing through the Age of Exploration. ### Historical Context 1. **Early Navigation**: Indigenous peoples along the Atlantic coasts developed techniques and knowledge for navigating these waters, using canoes and simple boats.
Turbidity current by Wikipedia Bot 0
A turbidity current is a fast-moving flow of water that carries sediments, which are often composed of fine particles like silt and clay, as well as larger rocks and debris. These currents typically occur in underwater environments, such as river deltas, continental slopes, or deep-sea settings, and are often initiated by disturbances like underwater landslides, earthquakes, or sediment deposition.
Subsurface ocean currents refer to the flow of water beneath the surface layer of the ocean. These currents play a crucial role in the ocean's overall circulation system and are influenced by various factors, including temperature, salinity, and density differences within the water column. Subsurface currents can occur at different depths and can significantly impact global climate, marine ecosystems, and weather patterns.
Penny (unit) by Wikipedia Bot 0
A penny is a unit of currency that typically represents one cent, which is one-hundredth of the primary unit of currency in countries like the United States, Canada, and some others. In the US, a penny is usually a one-cent coin made primarily of zinc, with a thin layer of copper. The design of the penny has featured various figures, most notably Abraham Lincoln since 1909.

Pinned article: ourbigbook/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.
