The Tempest Prognosticator is an early meteorological device developed in the 19th century, specifically designed to predict storms and weather changes. It was invented by the British scientist George Merryweather in 1851. The device consists of a series of eight glass tubes filled with liquid (often mercury), each equipped with a float connected to a bell. When atmospheric pressure changes, the floats rise and fall, triggering bells to ring.
A Whole Sky Camera (WSC) is a specialized imaging device designed to capture photographs or video of the entire sky. These cameras provide an unobstructed view of the sky, typically covering a 180-degree or 360-degree field of view, making them useful for various applications, including: 1. **Meteorology**: Whole sky cameras are used to monitor cloud cover, weather patterns, and atmospheric phenomena.

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.
