<p>
Recently, I have been studying physical optics. I found the formulas that are given in the textbook in the section of profound Young's double-slit experiment are quite "approximate". Since I always have the belief that Physics should be progressed in a mathematical manner with rigorous deductions and proofs, I decided to deduct some of the parts by myself and also try to prove the conclusions that are given in the textbook without proofs.

<p>
In this series of posts, I will talk about the reasoning about knowledge like how to reach an agreement under different harsh conditions. This field is called <a href="https://en.wikipedia.org/wiki/Epistemic_modal_logic">Epistemic modal logic</a> and this post will mainly discuss reaching agreement in the presence of faults in the distributed system.
