Gizmo

"Wikis", such as the online encyclopaedia Wikipedia, provide an easy way to post and maintain information. But vandals can all too easily deface them. So Andrew McNab at the University of Manchester, UK, has developed a form of wiki that uses digital certificates to identify writers. Once a user has been awarded a certificate, it …

ALICE and Bob are having an argument. They are looking at the same space, but while Alice sees only emptiness Bob sees lots of particles.
