Homonymy refers to the phenomenon where two or more words share the same spelling or pronunciation but have different meanings. In linguistics, homonyms are classified mainly into two categories: 1. **Homographs**: These are words that are spelled the same but have different meanings and may or may not be pronounced the same. For example, the word "lead" can refer to a type of metal (pronounced "led") or to the act of guiding (pronounced "leed").
Optical illusions are visual phenomena that trick the brain into perceiving something that is not actually present or interpreting an image in a way that differs from reality. They occur when our visual system misinterprets information received from the eyes due to the way our brains process visual signals. There are several types of optical illusions, including: 1. **Physical Illusions**: These arise from the physical properties of the stimulus, such as perspective and lighting.

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.
