In case anyone is interested here is a link to a very difficult logic puzzle that anyone without math skills can solve (it is easy to understand though). I also include the answer with a CW for those who want to skip right to the answer.

@erou I start reading the paper. It looks based on the Ytang Zhang who gets the greatest improvement on the twin prime conjecture in 2014 using a Erathosthène like sieve (see en.wikipedia.org/wiki/Yitang_Z) the result was greatly improved one year later (polymath project). The authors have use this sieve in a preceding paper to prove a formula and bounds on the Euler function for twin primes which lead to their result.

I did not read it in details but the proof seems "elementary": no use of very sophisticated mathematics.

An article [1] claiming that the twin conjecture is solved! If anyone has a clue whether it seems true or not...

Un an que je vais régulièrement à Londres et je n’ai toujours pas percé un des plus obsédants mystères d’outre-Manche : pourquoi diable les Anglais tiennent-ils leur droite dans les escalators alors qu’ils roulent à gauche (et circulent à gauche dans les couloirs de métro) ??
