The math of threes is surprisingly powerful.
It’s difficult to imagine that three random words have the power to both map the globe and protect your private data. The secret behind this amazing power is just a little bit of math.
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. If your brain operates more naturally in the Imperial measurement system, 3 meters is about 9.8 feet. 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. As an example, there’s a square in the middle of the Rochester Institute of Technology Tigers Turf Field coded to brilliance.bronze.inputs.
This new approach to geocoding is quite useful for several reasons. First, it’s more precise than regular street addresses. In addition, three words are easier for humans to remember and communicate to one another than, say, detailed latitude and longitude measurements. Because of this, the system is well suited for emergency services. With these advantages, some car manufacturers are even starting to integrate what3words into their navigation systems.
