Causality(Q179289) is an assertion that states that one event is the direct consequence of the other. The mathematical model of causality has been investigated by Judea Pearl[1][2]. In the book:Picturing Quantum Processes[3]Cite error: Invalid <ref> tag; invalid names, e.g. too many, the following statement is said about causality.

Key Opinion Leaders

Judea Pearl's Interpretation of Causality

Judea Pearl literally created a science[2] and a model of computation[1] on this subject matter. He has a one hour video[4] on this subject.

Leslie Lamport's Interpretation of Causality

Leslie Lamport created the Lamport Algorithm which provides a infrastructure to synchronize or give logical time ordering of events across distributed systems. In this paper:Time, Clocks, and the Ordering of Events in a Distributed System[5], he not only presents the algorithm required to prescribe the algorithm, he also invoked his understanding of the physical meaning of causality, and talked about the use of state machine as a model of computation to help him think through the system.

Bob Coecke's Interpretation of Causality

Bob Coecke talked about causality in this video[6]:From quantum processes to cognition via pictures. He even stated that a simple diagram with just one discard symbol can represent the entire Theory of Relativity. One may also look at the video[7] by Jonathan Barrett.

If the output of a process is discarded, it may as well have never happened.

Kyle Cranmer's Interpretation on Causality

Kyle Cranmer has a 90 minute video[8] on Causality.

Sean Carroll's Interpretation on Causality

Sean Carroll has an 80 minute video[9] on Causality.
