Yes, there are coincidences in all fields of mathematics as well. From the Feynman point to Nikola Tesla's belief of singularity, a mathematical coincidence happens when two mathematical expressions or equations without mathematical prove or theoretical explanation show a value or variation that is either equal or almost equal. Let's see what you know about mathematical coincidences by taking this quiz.
