Our team noticed that a series of exponential curves could be devised so as to continuously and regularly grow apart. On a graph of such curves, there will always eventually be a transverse where each line is 1 cm away from the next. Then later on, they’ll eventually all be one INCH apart. And so on! In this way, every possible unit of distance can exist on a single ruler. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eEven ad hoc units you may need when least expected (e.g. “how many of these paper-flowers-I-made is this sheet of construction paper long?”). Really big units (like light years) can only be partially represented, of course, but by placing the curves on a cylinder just right, we managed to make the whole device continuous. \u003c\/span\u003e\u003c\/p\u003e","brand":"The Curiosity Box","offers":[{"title":"Default Title","offer_id":52519870398695,"sku":"CB-UniversalRuler","price":49.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0328\/3602\/6508\/files\/Untitleddesign_6.png?v=1788555488","url":"https:\/\/www.curiositybox.com\/products\/ruler-of-the-universe","provider":"The Curiosity Box","version":"1.0","type":"link"}
