There are two primary approaches to creating something: bottom-up design and top-down design . Top-down design is often seen in architecture. People do not build bricks randomly; instead, they follow the design drawings created by the architect. This method executes a plan that has already been established. When asked why something is built in a certain way, the answer is usually that the blueprint dictates its design. Conversely, bottom-up design does not start with a fixed goal, but rather involves setting and implementing small, actionable rules. For example, termite nests follow this approach. Small termites have a simple rule: to pile up soil. They do this without knowing the reason, but over time, the finished structure is remarkable and sophisticated. The appearance of the Sagrada Familia church , designed by Antoni Gaudà and still under construction, closely resembles a termite nest, differing only in size. Setting goals and planning is one way to create, but actual achievem...
The "normal human body temperature = 37°C" standard was established in 1851 by the German medical doctor "Carl Reinhold August Wunderlich", who took millions of temperature readings from about 25,000 people and reported "36.2°C to 37.5°C". However, surveys in the United States in 1992 and the United Kingdom in 2017 found 36.8°C and 36.6°C, respectively. So in the past people deemed that the discrepancy was due to errors in old measuring equipment or methods. But Julie Parsonnet and her colleagues at Stanford University's School of Infectious Disease Epidemiology found a common thread in the temperature databases: People are cooler now than they were then. It wasn't just a measurement error. They speculated that medical advances had reduced inflammation and lowered the average temperature. We don't question the obvious. - Joseph’s “just my thoughts”
