Behind the scenes[[edit] | [edit source]]
Though AUDIO: The Haunting establishes that 1 is itself considered a prime number in the DWU, this is a point of contention among mathematicians. There was significant disagreement as to whether to classify 1 as a prime number in the story's time period of the 1890s. In particular, the entry for Number published in 1890 in the 9th edition of Encyclopædia Britannica stated that every positive number was either prime or composite, and explicitly listed 1 as prime.[1] Nowadays, in the 21st century, 1 is instead generally considered as neither prime nor composite. To further complicate real-world existence of 1 as a number, there have even been periods of time - like Ancient Greek era - where 1 was in fact not even considered a number.[2] This included notable mathematicians like Aristotle and Euclid.[3]
Though unremarked in PROSE: Daisy Chain, 1 is also the first and second Fibonacci number.
