Physics Perspective is a personal blog at physicsoffinance.blogspot.com about economics and science. Since 2011, 4 different Hacker News readers have linked it 7 times. The last post was in 2017, but the archive is still widely read.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link Mark Buchanan's blog, which applies physics ideas to economics, finance and social systems, with literature-review posts on market anomalies and simulation.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
This blog explores a growing revolution in the science of markets based on ideas and concepts from physics. If traditional economics has emphasized self-regulating processes and the concept of market equilibrium, the new perspective emphasizes the myriad positive feed backs which often drive markets
What Hacker News says?
That's not necessarily true. A market anomaly does not disappear instantaneously, but instead decays gradually as it is exploited and in turn becomes harder to exploit. Think of it as a radioactive half-life. Some research (I found the link on Mark Buchanan's blog http://physicsoffinance.blogspot.com/ ) suggests that half-life is quite long.

HN discussionThe author of the article, Mark Buchanan, has a blog [1] titled "Physics Perspective" and subtitled "Inspiration from physics for thinking about economics, finance and social systems". Lotsa interesting stuff; I saw one article which said that stable economic growth in developed countries tends to be linear.

HN discussionRather than go point by point, I'll refer you to someone more eloquent and credentialed. Check out some of Mark Buchanan's comments on http://physicsoffinance.blogspot.com He talks about many things, but if you're curious you'll find several lit review posts about this topic. The heart of good science is solid theory followed by experimental evidence. Simulations such as the El Farol Bar problem demonstrate how syst…

on “Algorithms Had Themselves a Treasury Flash Crash”The Santa Fe Institute is awesome. I'm especially a fan of Mark Buchanan ( http://physicsoffinance.blogspot.com/ ). I also found that simulations weren't exciting to the economists in my program. My advisor suggested I move to Paris. He followed his own advice shortly after.
