This is why I will defend our Posties until my dying breath. A parcel dumped at an address a *long* way away, by Amazon, whilst insisting it had been personally handed to me. Their “customer service” couldn’t have cared less. 5 days later it shows up, because my postie had spotted it on a doorstep, recognised my name, and went out of his way to bring it to me. It’s time Royal Mail started treating these people with the respect they deserve.

Revisiting one of my earlier blog posts on the #Collatz conjecture. Is it possible to prove that 3n+1 will eventually reach 1 for all real positive integers? Recap and progress: davechessgames.blogspot.com/2012/02/puzzle… #math #maths

Generative AI proves the #Collatz #Conjecture by demonstrating a 1-4 dimensional construct contains all Collatz sequences. #Maths davechessgames.blogspot.com/2024/04/genera…
