On Emergence and Whole Systems

This is a followup to Freeman Dyson Making Complete Sense of Modern Physics.


Listen to Sabine Hossenfelder talking about emergence in modern theoretical physics.


Here's the comment I made on YouTube:
1:02 I don't think that the atoms in a gas need to move periodically for the sound to be transmitted, do they? I can imagine in the case of standing waves they might do, and I think sonic refrigeration is an example of such a case, but I can also imagine a pressure wave propagating through a gas without inducing any kind of harmonic motion in the constituent particles. Indeed, it seems you need random motion to maintain the isometry and the acoustic properties of the macro-system. This might seem a bit nit-picking, but I think it matters when we are trying to pin down emergent phenomena and epiphenomena and whether there is a difference.
Now see how a control systems engineer sees the world:


... and how he interacts with it:


Recall the discussion by Dyson of Bohr and Rozenfeld's apparatus and compensation in measurements of the electric and magnetic fields, at 7 minutes.

Now see Dave Gilmour on Guitar Sound
and this:


See How To Be A Genius, in particular this brief interview with Alison Gopnik:


On normative models, see David Lewis' excellent Convention.

Which should help you all understand this:


... and show you how to avoid this: Record Money Market and Tech Fund Inflows and it might even improve your disastrous love lives! Hannah Fry on Mathematising Humanity.


On the reason why Nature must necessarily include an irreducibly random element, see On Free Will and Conscious Awareness.

What is the point of all this? It's Polly Samson's Theatre for Dreamers.

Stefan Molyneux on Resource Based Economy

Image
This is an interesting discussion. What most people don't realise is that capitalism as we practice it now wastes 99.9% of the human and material resources we currently use. Once you realise that, the problems raised by the idea of gift or resource-based economies become much more tractable. At  10 minutes 30 seconds  the discussion turns to the way we treat our family and friends differently. We don't charge our nearest and dearest. At this point Molyneux brings in Neo-Darwinian evolution to explain why there is this difference between the way we treat our kith and kin to the way we treat everybody else. I guess he will go on to argue that this is because we evolved to be like this, otherwise we would not have survived. He will presumably say that this is human nature and because it is genetically determined, nothing we can do short of a programme of eugenics and euthenasia will change that. Well, ... you know what my answer to that will be, ... something along the lines:

Nikola Tesla and the End of The World

At  1 minute 21 seconds  the building in the background, in Trafalgar Square , as she says "There is a story in our family that my great grandfather worked with Nikola Tesla, ..." is ... ... what? Hint: it is near to a statue of George Washington, a replica donated by the  Commonwealth of Virginia in 1921 .  See  War Crimes . Watch all four episodes of  Nikola Tesla and the End of The World  and then watch this: And on the meaning of the word sovereignty see: On the Mason-Dixon Line, the "boundary of slavery" in the American colonies, it might be insightful to compare the  Britannica  and  Wikipedia  entries and see where they differ. Then, especially if you're my daughter, see  On Feminist Genealogy . Then see this documentary about Mark Knopfler and what motivates his music. There's a nice bit at  17 minutes  about where songs come from, and what happens to their origin, and the role of Town Planners like my father, in this process, part

Sabine Hossenfelder - Lost in Math

Image
Sabine's book,  Lost in Math published in 2018. See  Rebecca Smethurst on the Crisis in Cosmology . Here's an interview on the subject of the book: At 16 minutes 27 seconds on aesthetics in a theory. I think you should worry first and foremost about whether or not it works, otherwise you are not doing empirical science. At 19 minutes 19 seconds on whether there would be better ways to advance physics other than by building the next generation of super high-energy particle collider. This is similar to military spending and it's really just an artefact of Keynesian monetary theory: that you can create 'wealth' by employing men to dig holes in the road and fill them up again. Of course you are not creating real wealth, you are destroying it and creating fake money. The upshot is that the better ways of spending much, much less money on encouraging sound scientific teaching and research are not of any interest, because they don't employ nearly so ma
