During the lecture, Sir Paul Nurse, starting from the fundamental principles of cell biology, systematically elaborated on the nature and characteristics of life in an accessible manner. Beginning with "the cell", he reviewed the key discoveries of scientists from Robert Hooke and Antoni van Leeuwenhoek to Theodor Schwann and Rudolf Virchow, emphasizing that the cell is the basic unit of life, and vividly explained how cells interact with their environment through boundaries and maintain internal order.

The lecture spanned five core sections: The Cell, The Gene, Life as Chemistry, Life as Information, and Evolution by Natural Selection. Sir Paul Nurse not only outlined key biological theories but also wove in stories of scientific giants such as Gregor Mendel, Louis Pasteur, and Charles Darwin. He emphasized that life is not merely a collection of chemical and physical processes but a complex system reliant on information storage and regulation; all life on Earth originates from a common ancestor and evolves and adapts through natural selection.
The lecture integrated historical perspectives, philosophy of science, and insights from modern biology, offering a profound answer to the fundamental question: What is Life?
