Mesofacts: slowly changing facts - Blog
"When people think of knowledge, they generally think of two sorts of facts: facts that don't change, like the height of Mount Everest or the capital of the United States, or facts that change a lot, like the weather or the stock market close. But in between there is a third timescale, with its separate category of facts: facts that change slowly, or mesofacts. This middle, or meso-, scale, of facts are the most interesting and yet the most slippery with which to be acquainted. These change over the course of a single lifetime but we tend to nonetheless view them as constant."

Warning: Your reality is out of date - The Boston Globe
"These slow-changing facts are what I term “mesofacts.” Mesofacts are the facts that change neither too quickly nor too slowly, that lie in this difficult-to-comprehend middle, or meso-, scale. Often, we learn these in school when young and hold onto them, even after they change. For example, if, as a baby boomer, you learned high school chemistry in 1970, and then, as we all are apt to do, did not take care to brush up on your chemistry periodically, you would not realize that there are 12 new elements in the Periodic Table. Over a tenth of the elements have been discovered since you graduated high school! While this might not affect your daily life, it is astonishing and a bit humbling."
