Logic After Thought

It's a nice change to hear a woman talking about this! The men all seem to say the same nonsense. At  13 minutes 38 seconds  she presents an interesting characterisation of the spectrum of conscious awareness. See  Julian Barbour Making Sense of Information  and  FT Illustrating The Problem With Modern Medicine , in particular this talk by Max Tegmark: At  4 minutes 32 seconds  Harris compares consciousness with switching on a light-bulb and finds the comparison fails. I think this is just because she does not understand how a light-bulb works. See Sabine is hard-nosed about art! See from  2 minutes 45 seconds . This statement by the artist "The machine depicts fictional beings from the future trying to communicate into their past". Sabine's comment could  be an indication that she understands it in the same way I do, in which case these beings are not fictional anymore,  or she could be indicating that she thinks it is no...

First see this post:  Hilary Putnam , then listen to this interesting little cul-de-sac in the history of modern physics which Freeman Dyson recounts. Is this experimental observation really sufficient to 'demolish Teller'? Isn't it also necessary to 'examine the record' and check that in fact Teller's hypothesis, if true, would not have any effect on the observation, say, of the age of the rocks used, or of the Universe? But whether or not it demolishes Teller, does it follow that it demolishes Dirac's hypothesis? I don't think so. These questions require a detailed examination of all the experimental data and the theories that were used to derive that data from the information produced by measurement apparatus. Here's Sabine Hossenfelder with some of the evidence that has been used to support the hypothesis of dark matter. Here is Sabine again on the discrepancy between the observed and calculated values of the cosmological const...

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...

I better say I why I switched off when she said "Thank you for giving me a platform to speak about climate Realism". It's just that after thirty-five years we haven't got a platform to speak about climate change yet. Sabine Hossenfelder interviewing Professor Tim Palmer on this New York Times opinion piece  How Scientists Got Climate Change So Wrong : See  Russian Government is Clearly NOT Taking Climate Change Seriously . And: Bye bye RT, bye bye Vladimir Putin. You're all as fake as Donald Trump and Boris Johnson. Instead of developing new technology and creating the economic conditions for stable economic growth the Russian government is playing the oil and gas market, and forcing other countries to do the same. They just don't get it. See  The Global Economic Joke .

See  Ben Eater on Running a Breadboard at 1MHz . See also Anton Petrov on correlations between peak solar activity and viral pandemics: See  Lori on Extraterrestrial Life . Once we start thinking about how much we don't  know, rather than just what we think we know, ... Well, then we are able to solve problems better, because we see many, many more possible courses of action. See  Coronavirus A War Against Humanity?  for some more connections in the cobwebs of life that may be relevant, such as patterns of wild bird migrations. See also: See also  A Science Project for Young Witches  for another extra-terrestrial connection with life on earth. For more on highly sensitive chemical reactions, see and for some technical details, see: Once we start talking seriously the interdependence of all life on earth, then we see clearly how we need to completely revise the way we do science, as well as the way we make decisions as to t...

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 Dyso...

This is really interesting! More interesting than Neo-whatsits, anyway, ... Here's an amateur doing the same scene: See  Rewrite - SciFi Short  for more on presentation and representation. See  Greek numerals  for an authoritative description of how the Greeks represented numbers. But I wouldn't have done it like that if I  were Greek. I would have cooked up a rule to save myself from having to invent new names for bigger numbers which are obviously fractal. See ... and: ... and: ... and on  Hausdorff dimension  see  Nathan Has 1,000 Subscribers : And on variable bases, see  Asymmetric numeral systems  which are form of  entropy encoding . On their uses in probability, see  Measuring Ignorance  and look up  Kullback–Leibler divergence ; then see  Aristotle on The Continuum : At  8 minutes 20 seconds  (500 seconds) Norman says "Eventually the numbers I'm g...
