Explore the fascinating history and science of paper, a material that transformed human civilization. The journey begins not with paper, but with its ancient precursor, papyrus, crafted by Egyptians from reeds along the Nile. The invention of paper as we know it is credited to Cai Lun, a court official in Han Dynasty China around 105 CE, who developed a revolutionary method of creating a lightweight and affordable writing surface from materials like mulberry bark and hemp fibers. This innovation, a closely guarded secret for centuries, eventually spread across the globe, forever changing the way information was shared. Learn about the significant environmental impact of recycling, where recycling one ton of paper saves enough energy to power an average American home for six months. Uncover the science behind why old books turn yellow, a chemical reaction involving a natural wood polymer called lignin. Delve into the mind-bending mathematics of exponential growth, which reveals that if you could fold a sheet of paper 42 times, its thickness would be enough to reach the moon.
