"'The #energy that flows through a system acts to organize that system,' Harold Morowitz wrote in 1968. Decades later he would team up with physicist Eric Smith at SFI, and the collaboration would lay out a new theory of #abiogenesis."
"According to Smith & Morowitz, life emerged b/c Earth’s geochemistry created an excess of chemical energy. Organic chemistry self-organize[s] when sufficient energy [flows] through the system. Given enough time, a self-maintaining chemical system emerges that can copy itself."
"'If life in its abundance were bound to arise, not as an incalculably improbable accident, but as an expected fulfillment of the natural order,' writes origins-of-life pioneer Stuart Kauffman of the Santa Fe Institute, 'then we truly are at home in the universe.'"
"We want to keep the right-hand side of this equation as close to zero as possible. What happens if you produce too much, the frequency increases, which we don't want for a variety of reasons."
‘‘Consider what it means to understand ‘The sports car passed the mail truck b/c it was going slower.’ You need to know what sports cars & mail trucks are, that cars can ‘pass’ one another, and that vehicles exist & interact in the world, driven by humans w/ their own agendas.’’

2/n This new research deploys #ScalingLaw insights to understand the population-density driven transition from temporary hunter-gatherer settlements to permanent sedentary city life.
3/n Previous research on the impact of densification on the transition into city life has yielded conflicting results, some suggesting that hunter-gatherer groups actually thin out as they scale. (In what ways might this reflect transitions in the scaling of microbial organisms?)
It's good to be back! Follow this thread for the video stream & live coverage of tonight's first SFI Community Lecture at @TheLensic in two years, featuring @Sara_Imari on the #physics of living #systems.
And stay tuned for an extraordinary lineup of additional talks this year...
💉 Without mandates, people’s opposition to #vaccines was softer than one might guess — only 3.3% of those surveyed. With mandates, resistance quintupled, to 16.5%.
“To increase and sustain vaccination rates, change people’s beliefs, and build trust. People have to feel that the guidance they’re getting from the government makes sense and is reliable. And it’s key to get the word out that the vaccines really work.”
– Katrin Schmelz
“We looked at the price of #coal over 140 years. Mines are much more sophisticated, the technology for locating new deposits is much better. Prices have not come down.”
- SFI's Doyne Farmer (@INETOxford)
