  • Some facts are bigger than numbers – a story

    Some facts are just boring, like 1 + 1 = 2. You already knew them before they were presented as such, and now that you do, it’s hard to know what to do with them. Some facts are clearly important, even if you don’t know how you can use them, like the spark plug fires […]
