Recognized as one of the most highly esteemed mathematical journals in the world, Annals of Mathematics has been in circulation since 1884. Published in partnership with Princeton University, the Annals was founded to explore questions and areas of interest in any areas of applied mathematics. For those interested in even earlier examination of numerical concepts, issues of The Analyst, the Annals predecessor from 1873 to 1883, covers interesting topics from theories behind zero and infinity to the tidal cycle.
