Initially, humans could not draw as they perceived. It was only after the discovery of perspective that they could accurately draw what they saw. Perspective was first applied to performance stages in Greece during the 5th century BC, and it was not until the 15th century that the Italian architect Brunelleschi succeeded in expressing a three-dimensional perspective on a two-dimensional plane. In the long history of humanity, the period of applying perspective is quite brief. Perspective painting represents a virtual depiction of reality. In other words, the first instance of visualizing something virtual is perspective. People speak as if the metaverse is a significant industry today, but the virtual realization through perspective began long before the digital era. Currently, it’s only visually represented digitally. Understanding the essence of this can help you mitigate risk, even as times and circumstances evolve. - Joseph’s “just my thoughts”
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”
