He is often portrayed as a wise fool or a comedic character who uses wit and humor to convey moral lessons and social commentary. His stories often feature absurd situations, clever tricks, and humorous dialogues that reveal profound truths about human nature, society, and daily life.
Roller electrospinning is a variation of the traditional electrospinning technique used to create nano- and microfibers from polymer solutions. In conventional electrospinning, a polymer solution is ejected from a syringe needle under the influence of an electric field, forming fibers that are collected on a target collector. Roller electrospinning, on the other hand, incorporates a rotating collector that is often shaped like a roller or drum.
"Anathem" is a science fiction novel written by Neal Stephenson, published in 2008. The story is set in a parallel universe where the world is structured in a way that emphasizes the separation of intellectual and secular life. The novel revolves around a society of scholars known as "avout," who live in monastic communities and dedicate their lives to the study of philosophy, mathematics, and science.
Silicon nanowires are nanoscale structures made of silicon that have diameters typically ranging from a few nanometers to several hundred nanometers and lengths that can be several micrometers or longer. These one-dimensional structures exhibit unique electrical, optical, and mechanical properties that differ significantly from bulk silicon due to their reduced dimensionality and increased surface-to-volume ratio.
"The Thief and the Cobbler" is an animated film that was originally conceived by British animator Richard Williams.

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.
