# Scientific Observations & Math

My last post was about science and newness. Modern science values new information more than existing information and rewards research that pushes forward into new territories. What unites new science in any field with the historical information that the new science rests on, is mathematics. As Yuval Noah Harari writes in his book Sapiens, “mere observations, however, are not knowledge. In order to understand the universe, we need to connect observations into comprehensive theories. Earlier traditions usually formulated their observations into stories. Modern science uses mathematics.”

Mathematics are used to communicate observations because mathematics can be objective, precise, and evaluated for accuracy.  My experiences of reality and how I may interpret and communicate that reality is not likely to be the same as the way someone in New York City, Tokyo, or Kabul experiences, interprets, and communicates their immediate reality. However, if we chose to measure our worlds through data and agree on the scales to use, we can begin to bring our subjective experiences of reality into a unified and consistent framework. A lot of how we understand the world is subjective. For example, I run a lot and a lot of my friends run, so a three mile run sounds short to me. However, for someone who doesn’t run often and doesn’t have friends who run often, a three mile jog may as well be a 26 mile marathon. Mathematics escapes the subjective, goes beyond stories and narratives that we may develop from our subjective experiences. It ties our collective experiences together into something more objective. Mathematics allows us to go from stories to real theories.

That still doesn’t mean we all understand and interpret the numbers the same. In his recent book How to Make the World Add Up, Tim Harford shares an example of national statistics in the UK showing that the average rail car has only 100 passengers. However, in Harford’s experience, traveling at rush hour, the average rail car is completely packed with far more than 100 people. The statistics can be viewed through a different reference point, through the average passenger traveling at rush hour, or through the rail car traveling throughout the day. Without mathematics we could never describe this reality in a consistent and unified way. Our descriptions of the world would be based on narrative and story. Mathematics gives us a grounding through which we can understand the universe in a more comprehensive and generalizable manner.
