A Quantum History of Space-Time.

Before arriving at these historically infused (and almost exclusively menonly) introductions to the quantum and cosmological questions at hand, Hertog offers an extensive chapter on how Darwinian evolutionary theory reconfigured biology, providing insights from which Hertog and Hawking would later borrow. A decent amount of background material is necessary in order to fully appreciate the ideas from which Hertog and Hawking drew to develop their no-boundary model of how the universe began. Hertog completed his doctoral work under the supervision of Hawking, which is explored in On the Origin of Time, and this led to an enduring research partnership that was still productive until nearly the end of Hawking's life.
