In a 1940s Atlantic City, family relationships, old age and illiteracy mix for a pipe-smoking child
The Wallace-Bolyai-Gerwien theorem states that any two polygons are equidecomposable: it is possible to cut any polygon into finitely many polygonal pieces and then rearrange them to obtain any other polygon.
The theorem doesn’t rely on the axiom of choice (unlike, for example, the more famous Banach-Tarski decomposition). Moreover, the decomposition and rearrangement (which consists of rotations and translations only) can by carried out “physically”: the pieces can, in theory, be cut with scissors from paper and reassembled by hand.
The problem about whether a hinged dissection exists, such as the ones in the animation, remained open until 2007. The paper Hinged Dissections Exist presents a method which always works to find a hinged dissection.

I love how someone CHEATING on someone else is somehow more of a crime in fiction than MURDERING SOMEONE.
I think this is largely because cheating is something we can comprehend. It’s something REAL to us. We can imagine being cheated on. It’s harder to imagine, for most people, being murdered.
Some of us HAVE been cheated on. None of us have been murdered.
But yeah also I’m sorry I know exactly who you’re referring to, and I love Kurloz and Damara and don’t care about Rufioh I’M SO SORRY.

The World’s Oldest Crown
The crown was discovered in a remote cave in the Judaean Desert near the Dead Sea in 1961 among hundreds of other objects from the period. Known as the ‘Nahal Mishar Hoard’, more than 400 objects were discovered by Pessah Bar-Adon and his fellow Israeli archaeologists in the cave which became known as the ‘Cave of the Treasure’. The ancient relic, which dates back to the Copper Age between 4000–3300 B.C., is shaped like a thick ring and features vultures and doors protruding from the top. It is believed the crown played a part in burial ceremonies for people of importance at the time.
