Welcome to Quezi, where talented professional researchers post answers to questions about almost everything.
Our researchers choose the questions they wish to answer, and you are invited to post suggestions here.
We would like to thank the photographers, artists and illustrators who have allowed their work to be used at Quezi. They have generously licensed their work (posted at Flickr and elsewhere) under a Creative Commons or similar license, or have released it to the Public Domain. By doing so, all of society can benefit from their creativity. Thanks!
Quezi is operated by Uclue Ltd and uses these technologies.
