Numbers2Know

numbers2know.org is a website that hosts a list of numerical values that are “important” for various reasons. The website is essentially a card box of numbers and can be used to memorize them. I wrote it in 2015 as a holiday project.

The list of numbers can either be accessed en bloc or explored randomly. In addition, there is a basic voting mechanism that allows visitors to up- or downvote records to rate their importance. For a brief account on my personal notion of “importance” see my note on record suggestions.

Ok. But why? There are three points to tell, namely:

• As physicist, I am fond of numbers by profession.
• I am also especially ungifted when it comes to memorizing them.
• I was on vacation and felt awkwardly unproductive.

The combination of 1 and 2 led to a growing list of important numbers I compiled for my personal use, to the end that I eventually might remember them for good. The 3rd point gave rise to this website — a public beautification of this list.
