Why is 1,729 an interesting number to Hardy?
Check the arithmetic yourself, then keep the anecdote and the math claim separate. This staged sample avoids the out-of-date 19 October guide and kit; the partition-number correction remains an open source-file fix.
Clue 2 · source detail
Fictional guide illustration · not evidence
9³ + 10³ = 1,729.
Compute the second pair independently.
Clue 3 · source detail
Fictional guide illustration · not evidence
Hardy tells the story in his published account.
The permitted quotation is Hardy’s only, word-for-word and labeled “as told by Hardy”; the arithmetic can be checked separately.
Make your own theory
Before you peek, what do you think the clues show?
Write or discuss an explanation in your own words. Then compare it with the sourced case note below. This preview doesn’t save responses.
What a careful answer can say: Both sums equal 1,729: 1 + 1,728, and 729 + 1,000. That verifies the arithmetic claim, not every detail of Hardy’s recollection.
What the evidence cannot settle: The calculation cannot independently verify the conversation or the visit Hardy describes. Keep that anecdote attributed to Hardy, and do not put words in Ramanujan’s mouth.
