Ask me about maths

Does anyone have any pressing mathematical questions which need answering? Are there any other mathematicians out there?

The Archimedian Property tells us that there is no such number. Given any real number x, we can find a natural number n such that n > x.
Knowing Joe, his brain will only deteriorate over time, meaning his favourite number will become progressively smaller as he struggles to process large numbers. By middle age, I predict that his favourite number will be 11 (he's clearly a fan of symmetry/rotations given his affection towards 88 and 69).8th member (for now) wrote: ↑Wed Mar 12, 2025 9:22 am As a child Joe’s favourite number was ‘88’. This changed to ‘69’ in his mid-teens.
Are you able to spot any patterns within these two numbers - aside of the on set of delinquency - and maybe then even predict what his next favourite number will be?
Thanks Neil, that is a great answer - most helpfulneil_thomson wrote: ↑Wed Mar 12, 2025 12:20 pmKnowing Joe, his brain will only deteriorate over time, meaning his favourite number will become progressively smaller as he struggles to process large numbers.

Wow thanks for the insight - really makes you think! There's so much we don't understand about the world.neil_thomson wrote: ↑Wed Mar 12, 2025 12:16 pmThe Archimedian Property tells us that there is no such number. Given any real number x, we can find a natural number n such that n > x.
But this is just one person's opinion. In reality, you'd struggle to find anything bigger than 151.

151 also has rotational symmetry depending on the font used. On a calculator it certainly does![]()
Very basic answer, but the coolest mathematical proof has to be Andrew Wiles' proof of Fermat's last Theorem. I have not read it (very long) nor do I know all the details, but the context around it is insane. There's a very good documentary about it (accessible to non mathematicians): https://www.bbc.co.uk/programmes/b0074rxx
