A barograph is a type of barometer that continuously records atmospheric pressure over time. It typically consists of a barometric pressure sensor connected to a pen that traces a line on a rotating drum or a digital display. As atmospheric pressure changes, the pen moves up or down, creating a graph that illustrates pressure fluctuations over the period of time being measured. Barographs are commonly used in meteorology to help track weather patterns and changes in atmospheric pressure, which can be valuable for forecasting weather.

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.
