(The what3words system works in 50 different languages with independently assigned words.) The next question is determining how many ordered triples of three random words can be made from a list of 40,000 words. The developers at what3words came up with a list of 40,000 English words. Yet even using only common English words, there are still plenty to go around. According to some scholars, there are more than a million English words. So “” would be considered a different ordered triple than “.” In fact, in the what3words system, is in fact on a mountain in Alaska, not in the middle of the RIT Tigers Turf Field, like .įinding out how many words are used in a language and whether there are enough ordered triples to map the entire world are the next steps. Dividing 510 trillion by 9 reveals that uniquely identifying each square on Earth requires around 57 trillion ordered triples of three random words.Īn ordered triple is just a list of three things in which the order matters. Therefore, working in the metric system, Earth’s surface area is equivalent to 510 trillion square meters. Remember: What3words is using 3-meter-by-3-meter squares, each of which contains 9 square meters of surface area. With r = 3,959 (6,371), this works out to approximately 197 million square miles (510 million square kilometers). To compute the surface area of the Earth, use the formula 4πr 2. Start with the basic assumption that the Earth is a sphere, recognizing that this is an approximate truth, and that its radius is approximately 3,959 miles (6,371 kilometers). Here’s how three random words in English or any other language can identify such precise locations across the entire planet.

Because of this, the system is well suited for emergency services. In addition, three words are easier for humans to remember and communicate to one another than, say, detailed latitude and longitude measurements. First, it’s more precise than regular street addresses. This new approach to geocoding is quite useful for several reasons. As an example, there’s a square in the middle of the Rochester Institute of Technology Tigers Turf Field coded to. So, you could think of them as approximately 10-foot-by-10-foot squares, which is about the size of a small home office or bedroom. If your brain operates more naturally in the Imperial measurement system, 3 meters is about 9.8 feet. What3words is an app and web-based service that provides a geographic reference for every 3-meter-by-3-meter square on Earth using three random words. The secret behind this amazing power is just a little bit of math. It’s difficult to imagine that three random words have the power to both map the globe and protect your private data. Use at your own risk.The math of threes is surprisingly powerful.
