The chemistry behind new and old book smells
cross-posted from: https://mstdn.social/users/compoundchem/statuses/112053145362352366
Image description: Infographic on the aroma of books. The smell of old books is produced by the gradual breakdown of cellulose and lignin in paper. Type of paper and age of the book affect the compounds produced, which include furfural, vanillin and benzaldehyde. The aroma of new books is equally variable, the compounds causing it coming from adhesives, inks, and chemicals used for paper treatment. Many of these chemicals are odorless themselves, but can react and contribute to the release of aroma chemicals.

Wiki - The paradox of tolerance states that if a society is tolerant without limit, its ability to be tolerant is eventually ceased or destroyed by the intolerant. Karl Popper described it as the seemingly self-contradictory idea that in order to maintain a tolerant society, the society must retain the right to be intolerant of intolerance.
