PAPER
The invention of paper is widely attributed to the Chinese philosopher and government official Cai Lun, who is said to have created a paper-making process around the year 105 AD. Before the invention of paper, people in China used materials such as bamboo strips, silk, and parchment made from animal hides for writing and record-keeping. Cai Lun's creation of paper revolutionized the way information was recorded and disseminated in ancient China, and it later spread to other parts of the world, including the Islamic world and Europe. The process of making paper has evolved over the centuries, but the basic principles established by Cai Lun have remained largely unchanged.
