Join 📚 Hadar's Highlights
A batch of the best highlights from what Hadar's read, .
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
Between the years 3500 BC and 3000 BC, some unknown Sumerian geniuses invented a system for storing and processing information outside their brains, one that was custom-built to handle large amounts of mathematical data. The Sumerians thereby released their social order from the limitations of the human brain, opening the way for the appearance of cities, kingdoms and empires. The data-processing system invented by the Sumerians is called ‘writing’.

#3—What would I do/have/be if I had $10 million? What’s my real TMI? In 2004, I was doing better than ever financially, and BrainQUICKEN was distributed in perhaps a dozen countries. The problem? I was running on caffeine, working 15-hour days, and constantly on the verge of meltdown. My girlfriend, who I expected to marry, left me due to the workaholism. Over the next 6 months of treading water and feeling trapped, I realized I had to restructure the business or shut it down—it was literally killing me. This is when I began journaling on a few questions, including “What would I want to do, have, and be if I had $10 million in the bank?” and “What’s my real target monthly income (TMI)?” For the latter, in other words: How much does my dream life—the stuff I’m deferring for “retirement”—really cost if I pay on a monthly basis? (See fourhourworkweek.com/tmi.) After running the numbers, most of my fantasies were far more affordable than I’d expected. Perhaps I didn’t need to keep grinding and building? Perhaps I needed more time and mobility, not more income? This made me think that maybe, just maybe, I could afford to be happy and not just “successful.” I decided to take a long overseas trip.
