The ISCB Fellow is an honor conferred by the International Society for Computational Biology (ISCB) to recognize individuals who have made significant contributions to the field of computational biology. This distinction is meant to acknowledge not only outstanding research contributions but also service to the community, leadership, and mentorship within the field. ISCB Fellows are typically elected through a rigorous selection process, and they are recognized during ISCB events, such as the annual ISMB (Intelligent Systems for Molecular Biology) conference.
The units of paper quantity can vary depending on the context and the type of paper being measured. Here are some common units and terms associated with paper quantity: 1. **Ream**: A standard unit typically consisting of 500 sheets of paper. This is one of the most common units used in the paper industry. 2. **Case**: A larger unit which usually contains multiple reams, often 10 reams (5,000 sheets) in a case for certain types of paper.
A radian per second (rad/s) is a unit of angular velocity in the International System of Units (SI). It denotes the rate of rotation or angular displacement of an object at a given time. Specifically, it measures how many radians an object rotates through in one second. Since a full circle is \(2\pi\) radians (approximately 6.
Acre can refer to different concepts depending on the context. Here are a few common meanings: 1. **Measurement of Area**: An acre is a unit of area commonly used in the United States and other countries for measuring large plots of land.

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.
