Welcome on numbers2know.org !
This website originated as a tool to learn, collect and sort numbers.
Not just any numbers: It provides a topically broad list thereof – worth to be memorized, not just as part of general knowledge, but as a benchmark to gauge the world we live in.
These numbers can either be explored one after another in a quiz-like fashion, or accessed in an aggregated, tabular form. In addition, there is a simple voting mechanism that allows visitors to up- and downvote records to rate their importance.
The purpose of numbers2know.org is not to provide a comprehensive list to look up numbers, but to encourage and support people memorizing selected numerical values of general interest.
