This and That

• In my post It comes soon enough I speculated on some future developments, among them:
  
  �I've been thinking... that... it would be possible to grow meat suitable for consumption without having to bother with the whole animal. [A] century from now, we'll have factories with organ bags that resemble nothing like animals at all.�
  
  In an interview of Time Magazine with Ray Kurzweil I read last week:
  
  �We'll grow in vitro cloned meats in factories that are computerized and run by artificial intelligence. You can just grow the part of the animal that you're eating."

• If you want more evidence that I have my thumb on the pulse of time: In my post Why'd you have to go and make things so complicated? I remarked on the the predictability of complex systems:
  
  �You don't need to predict the dynamics of the system. You just need to know what parameter space it will smoothly operate in so optimization works.�
  
  A recent article by Seed Magazine quotes Tom Fiddaman who, in collaboration with MIT and the Sustainability Institute, examines the policy implications of dynamic complexity in climate and economic models:
  
  �You are in a sort of dance with this complicated mess,� he says, explaining that it is impossible to determine the individual steps of this �dance��and this is in some sense the error of current thinking. Instead, we need to be able to construct robust solutions that provide general guidelines for what style of dance we should be doing. They need to be flexible and capable of withstanding the inevitable unpredictable behaviors of complex systems.
  
  The whole article, titled Knowing sooner, is a very recommendable read.


• I just learned that since July 1st, fast internet access is a legal right in Finland. Don't have much to say about it, just find it noteworthy.


• Most concise paper ever: Unsuccessful treatment of writer's block.


• I spoke to a science writer about What's at the center of black holes - and then forgot about it.
  
  �From a theoretical point of view, the singularity is something where something becomes infinitely large,� said physicist Sabine Hossenfelder at the Nordic Institute for Theoretical Physics. [That's not what she wrote, but what I actually said.]
  
  No one can be sure that their singularity doesn't describe a physical reality, Hoss[en]felder told Life's Little Mysteries. But most physicists would say that the singularity, as theorized by equations, doesn't really exist. If the singularity was �really real,� then it would mean that �energy density was infinitely large at one point,� exactly the center of the black hole, she said.
  
  However, no one can know for sure, because no complete quantum theory of gravity exists, and the insides of black holes are impossible to observe.


• My recent paper with Xavier Calmet and Roberto Percacci just got published.

I wish you all a nice weekend and don't forget to light the 3rd candle.
