Mathematical proofs are one of the most distinguishing beauty of mathematics. But the taken for granted beauty “on the other side” are the fallacies. These are construction of mathematical proofs that conceals some errors and inconsistencies and therefore presents an untrue statement to be true. One example of such is a classic proof that 1 […]

## Proofs and Jokes Have a Lot in Common

Proofs and jokes have a lot in common. One similarity is their structure. Just as the conclusion of a proof must be justified by the premises, the punch line of a joke must be supported by a series of statements. The following joke provides an example. During a flight from Warsaw to New York, members […]

In this post, I am going to prove something fun — something that is counterintuitive. If you love challenge, think about the proof and justify why it is right or wrong. In this post, I […]
