A batch of the best highlights from what Hadar's read, .
Geographical, biological and economic forces create constraints. Yet these constraints leave ample room for surprising developments, which do not seem bound by any deterministic laws. This conclusion disappoints many people, who prefer history to be deterministic. Determinism is appealing because it implies that our world and our beliefs are a natural and inevitable product of history. It is natural and inevitable that we live in nation states, organise our economy along capitalist principles, and fervently believe in human rights. To acknowledge that history is not deterministic is to acknowledge that it is just a coincidence that most people today believe in nationalism, capitalism and human rights.

Indeed, there was an easy way to ascertain the distance of the transmission source. Just respond to the message, and if the other party replies quickly to the response, the Trisolarans could determine the distance based on the round-trip time and the speed of light. Or maybe they would take a really long time to reply and cause the Trisolarans to be unable to determine how long the message was en route. But the question was: Would the other party reply? Since this source had actively sent out a call into the universe, it was very likely that they would reply after getting a response from Trisolaris. And the listener was sure that the Trisolaran government had already given the order to send a message to that distant world to lure them to respond. Maybe the message had already been sent, but maybe not. If the latter was true, then the listener had a singular chance to make his own humble life glow. The listener dashed in front of the operations screen and composed a short, simple message on the computer. He directed the computer to translate the message into the same language as the message received from the Earth. Then, he pointed the listening post’s antenna in the direction the message from Earth had come from. The Transmit button was a red rectangle. The listener’s fingers hovered above it. The fate of Trisolaran civilization was now tied to these slender fingers. Without hesitation, the listener pressed the button. A high-powered radio wave carried that short message, a message that could save another civilization, into the darkness of space. Do not answer! Do not answer!! Do not answer!!!
The Three-Body Problem
Cixin Liu and Ken Liu
A stored food surplus built up by taxation can support other full-time specialists besides kings and bureaucrats. Of most direct relevance to wars of conquest, it can be used to feed professional soldiers. That was the decisive factor in the British Empire’s eventual defeat of New Zealand’s well-armed indigenous Maori population. While the Maori achieved some stunning temporary victories, they could not maintain an army constantly in the field and were in the end worn down by 18,000 full-time British troops. Stored food can also feed priests, who provide religious justification for wars of conquest; artisans such as metalworkers, who develop swords, guns, and other technologies; and scribes, who preserve far more information than can be remembered accurately.
