+	Abstract
+	In his 1685 paper “Observationes cyclometricae” published in Acta Eruditorum, Adam
+	Adamandy Kochanski presented an approximate ruler-and-compass construction for rectifi- ´
+	cation of the circle. It is not generally known that the first part of this paper included an
+	interesting sequence of rational approximations of π. Kochanski gave only a partial explana- ´
+	tion of the algorithm used to produce these approximations, while promising to publish details
+	at a later time, which has never happened. We reconstruct the complete algorithm and discuss
+	some of its properties. We also argue that Kochanski was very close to discovery of continued ´
+	fractions and convergents of π.

+	According to our best theories of physics, the fundamental building blocks of matter are not particles, but continuous fluid-like substances known as 'quantum fields'. David Tong explains what we know about these fields, and how they fit into our understanding of the Universe.

He showed me the "Old Town" that had been so badly trashed by Hitler that during restoration they had to revert to paintings by Canaletto, who painted city portraits all over Europe in the 1700s, probably using a camera obscura.

+:23:36 From Carl Lazarus To Everyone:
+	Why 12,288 dimensions?  Why not more, why not fewer?
+:25:53 From tedpk To Everyone:
+	The same concepts are being used all of the time by gmail -- but it never learns about "my style" -- a fundamental limitation on by design?
+:26:42 From Mark Edelman To Everyone:
+	I wonder why the numbers in the vector have so many digits in them. Does this “precision” increase with training?
+:32:58 From Carl Lazarus To Everyone:
+	# of dimensions = 3*2**12   was that just a choice of how much they could handle with some amount of computing power?
+:46:09 From Barry Kort To Everyone:
+	In Otter Speech-to-Text, sometimes Otter will go back and change an earlier word.  But GPT locks in a word once chosen, never going back to alter an earlier word.  Would that practice ever become an advance in these narrative language models?
+:48:28 From Carl Lazarus To Everyone:
+	"The sky is blue".  Blue is a good choice after "The sky is" but "is" by itself doesn't particularly map to "blue".  So the whole of the sentence so far determines the probabilities for the next word, correct?  How long a sequence is considered?
+:55:02 From Carl Lazarus To Everyone:
+	So far, this explains how ChatGPT can construct a reasonably sentence or even paragraph based on word relationships.  But how does it take into account the prompt you gave it?
+:20:10 From tedpk To Everyone:
+	It is obvious that the human brain doesn't work in this manner -- we have lots of neurons -- but only a "relative few" are operating at one time [total power consumption is muc too low to work like GPT

+	• Socrates: “Prompt Engineering the name of the game” (even with humans).
+:03:23 From Carl Lazarus To Everyone:
+	There was a recent news item about some method of "poisoning" images so chatbots would be badly disrupted if they scanned them.  Does anyone know more about this?
+:07:06 From Conor O'Mahony To Everyone:
+	A new tool called Nightshade makes subtle changes to the pixels of an image—changes that are invisible to the human eye but trick machine-learning models into thinking the image depicts something different from what it actually does. When artists apply it to their work and those images are then hoovered up as training data, these “poisoned pixels” make their way into the AI model’s data set, and cause the model to malfunction. Images of dogs become cats, hats become toasters, cars become cows. The results are really impressive, and there is currently no known defense.
+	https://www.technologyreview.com/2023/10/23/1082189/data-poisoning-artists-fight-generative-ai/
+:08:11 From Barry Kort To Everyone:
+	Visual artists frequently construct synthetic images which are “unworldly” to arrest the attention of the viewer.  Such “unworldly” visual images can also confuse a synthetic image analyzer.  Optical illusions are commonplace examples, but other-worldly scenes are a staple of the visual arts.
+:29:55 From Jerome Slate To Everyone:
+	Question on Digital Rights. How will ChatGPT access proprietary (digital) information, i.e., a copywritten digital textbook? Could ChatGPT "buy" one copy and then use that to answer queries without infringing on the copyright because it is using its own "words".
+:32:39 From Barry Kort To Everyone:
+	“Digital Rights” raises the question of what does it mean to “Publish” something (e.g. make the content available to the general public).

+	What is the role of Carl Sagan’s “Baloney Detection Kit” or Joe Biden’s notion of “Malarkey” in assessing the validity of content culled from the Common Crawl, et al.
+:46:57 From tedpk To Everyone:
+	The logarithmic scaling with CPU ops implies that the systems will be running into major roadblocks due to inefficient usage of computer tech
+:03:55 From Barry Kort To Everyone:
+	Are chatbots vulnerable or immune to nefarious “grooming”?
+:24:41 From Judy & Mike Alexander To Everyone:
+	If one were to ask whether a human or animal is sentient, one would take *physical* measurements.  One would not simply engage the human in wordplay.

+	Train the LLM on Bach and ask it to create -- see if it makes us a Beethoven's 9th
+:41:14 From Barry Kort To Everyone:
+	Ray Kurzweil pioneered the synthetic compositions of “elevator music” in the style of half a dozen musical genres based on statistical models of each genre.  Some of the genres were Jazz, Latin Jazz, Baroque, Classical, and Country.
+:45:33 From Barry Kort To Everyone:
+	Mozart and Bach (among others) developed  a statistical process called “Dice Music” in which musical motifs could be synthesized by rolling the dice and entering the values into a table that selected the next note in sequence.
