	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.

	Quantum Fields: The Real Building Blocks of the Universe - with David Tong  6,065,075 views  Feb 15, 2017
	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. 
	
	David Tong is a professor of theoretical physics at Cambridge University, specialising in quantum field theory.https://youtu.be/zNVQfWC_evg?si=N0-udysPRZ4ZS4jT

10:07:06 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.

	what would happen if I let go of a helium-filled balloon
	
	ChatGPT
	If you let go of a helium-filled balloon, it would behave quite differently than dropping an apple due to the physics of buoyancy and the properties of helium. Here's what would happen:
	
	Buoyancy: Helium is a gas that is lighter than air, which means it has a lower density than the surrounding air. When you release the helium-filled balloon, it experiences an upward force called buoyancy, which opposes the force of gravity.
	
	Ascending Motion: As a result of buoyancy, the helium-filled balloon would start to rise into the air. It will continue to ascend until the upward buoyant force is balanced by the downward force of gravity. During this ascent, the balloon may move vertically and might also drift horizontally due to wind currents.
	
	Constant Speed: Once the balloon reaches a certain altitude where the density of the surrounding air matches the density of the helium-filled balloon, it will stop accelerating and reach a point of constant speed.

	If photons are in orbit around a black hole, as stated in the video, classical physics says they should radiate … right?  Is a quantum theory required?
10:48:29 From John Howard to Everyone:
	I think it's electrons, not photons, that radiate when deflected.
10:49:07 From Barry Kort to Everyone:
	Individual photons are the smallest (“quantum”) unit of radiation and cannot divide into any smaller units. They _are_ the radiation, all self-contained in one photon.

10:24:09 From Bob Primak to Everyone:
	The spire was built originally using timber which began green. This means using only trees with very straight grain.
10:26:08 From Bob Primak to Everyone:
	Forest management means selectively cutting a small number of trees in a cycle spanning several to many years. Weston, MA was managing their Town Forests until the 1980's, I'm told. This practice is totally sustainable, and does not harm the overall health of the remaining forest.
10:29:57 From Bob Primak to Everyone:
	The Spire was not original to Notre Dame Cathedral. it was added during a renovation in 1859.
10:31:32 From Bob Primak to Everyone:
	Iron supports and staples were used in other cathdrals as well. Amiens even used an "iron chain" all the way around the main structure to stabilize it.
10:32:54 From Bob Primak to Everyone:
	(Amiens was buitlo later than Notre Dame.)
10:33:01 From Bob Primak to Everyone:
	built
11:16:15 From Barry Kort to Everyone:
	For what it’s worth, ChatGPT says this:  The French government has owned Notre-Dame Cathedral since the French Revolution. The cathedral, along with all other churches in France, was confiscated by the state during the French Revolution in the late 18th century.
	
	However, a significant legal change happened with the 1905 French law on the Separation of the Churches and the State. After this law, the French government owned the cathedral, and the Catholic Church was granted exclusive rights to use it for religious purposes. The Archbishop of Paris is responsible for its use and maintenance, and the French state covers all renovation and restoration costs.
	
	It's important to note that the Vatican never really had legal ownership of Notre-Dame Cathedral. Before the French Revolution, the cathedral was owned by the Catholic Church in a broad sense, but the Vatican as an entity didn't have direct ownership.
11:20:05 From Barry Kort to Everyone:
	Google Bard says this:  The Vatican never ceded legal ownership of Notre Dame Cathedral to the Government of France. The cathedral is a national monument of France and is owned by the French state. The Vatican has always had a close relationship with Notre Dame, and the Pope often visits the cathedral during his trips to France. However, the Vatican has never had any legal claim to the cathedral.
	
	The confusion may have arisen from the fact that the Vatican was involved in the restoration of Notre Dame after it was damaged in a fire in 2019. The Vatican donated $10 million to the restoration effort, and Pope Francis sent a team of experts to help with the repairs. However, this does not mean that the Vatican now owns the cathedral. The Vatican's donation was simply a gesture of goodwill and support for the French people.

10:24:56 From Bob Primak to Everyone:
	It wasn't, as far as has so far been published.
10:36:32 From Barry Kort to Everyone:
	Einstein had a fourth gyrus (ridge) in the left frontal cortex which only about 10% of the human population have. Neuroscientist Dean Falk hypothesized that this extra gyrus hosted the kind of systems thinking that Einstein was gifted at. You can look up the literature on Dean Falk and her analysis of Einstein's brain.  PBS Nova aired an episode on it with host David Pogue (who also has that uncommon 4th gyrus).

	Nancy is right about autistic people having issues with scanning equipment.
11:00:26 From Bob Primak to Everyone:

	One problem with the name ‘Autism" is that Freud originally proposed to call it “Autoerotism" but Eugen Bleuler balked at that name, and shortened it to ‘Autism.” An alternative name was “Ipsism" which you might want to rule out for similar considerations.

	Mood has a valence attached to a stimulus ~ Appetitive vs Aversive ~ wanting more of the stimulus (approach) or wanting less (avoid).
11:22:03 From Barry Kort to Everyone:
	Regarding mood, a “neurosis" arises when you have mixed feelings. Part of you is curious, fascinated, and intrigued, but another part of you is apprehensive.

10:09:43 From Harry Forsdick to Everyone:
	If it takes 8 minutes for light to get from the Sun to the earth, why does it take approx 20 min for radio to get from Mars to earth?  Does light travel faster than radio?
10:11:16 From Barry Kort to Everyone:
	It depends on whether Mars is on the same side of the sun as the Earth, or diametrically opposite.
10:11:35 From Steve Isenberg to Everyone:
	From Quora: The distance of Mars from Earth varies while they are orbiting Sun.The shortest distance is 34.6 million miles when Mars is 3.09 light minutes away and longest distance is 250 million miles when Mars is 22.36 light minutes away.On average Mars is 12.72 light minutes away.Two way telephone communication time from Mars to earth on their shortest distance is 6.18 minutes and on their longest distance is 44.72 minutes.
10:15:45 From Judy & Mike Alexander to Everyone:
	I don't understand why Scott Kenyon talks about colors in the JWST images.  They are false colors, put in by NASA.
10:16:16 From Bob Primak to Everyone:
	To simplify about Mars:
10:16:40 From Bob Primak to Everyone:
	To simplify about Mars:At solar conjunction, Mars is as far away as it can be from Earth, at nearly 249.1 million miles.
	That's twice or more the distance from Earth to the Sun (93 million miles). At the closest approach, Mars is only 36 million miles from Earth, making it a much shorter trip for the radio waves. So that 20 min. figure varies depending on where Earth and Mars are relative to one another. Also, remember, there is processing time for the signals, and the entire transmission is not a single radio wave pulse. That 20 mins is for the entire image to arrive, not the first radio pulses.
10:18:01 From Ted Kochanski to Everyone:
	if the Milkyway is forming a few stars per year -- on the average with Orion having a few thousand or more "new" stars --and  we had assumed that places like Orion formed a lot of stars at once -- is this still an operative model?
10:18:12 From Bob Primak to Everyone:
	If Steve's source is correct, 20 mins would be round-trip time at about half the longest possible Earth-Mars distance.

10:49:59 From Bob Primak to Everyone:
	Feynman Lectures in Physics:  Feynman argues that centrifugal force is *real*.\ 
	
	The centrifugal force is very real if you are in a rotating reference frame. It causes objects in a rotating frame of reference to accelerate away from the center of rotation. Washing machines, uranium enrichment centrifuges, and biology lab centrifuges all depend on the reality of the centrifugal force .

10:50:10 From tedpk to Everyone:
	in 1987 my brother supervised by Prof Greytak trapped neutral hydrogen atoms in a magnetic field
11:03:14 From Justin Tse to Everyone:
	So, because the two particles have the same and opposite spin orientation at time T1 and then the same at time T2 (when separated), this is a type of "memory" of prior more local entanglement?
11:11:52 From Carl Lazarus to Everyone:
	How do you create an entangled pair of photons or electrons?
11:14:40 From Mark Edelman to Everyone:
	A rather broad question: are you satisfied with a conventional definition of information, as valid in the context of entanglement across distances? Is there any reason to see information differently?
11:17:54 From Mark Edelman to Everyone:
	How does one KNOW that two particles are still entangled?
11:19:26 From tedpk to Everyone:
	in my brother's work spin-polarized hydrogen was trapped in a magnetic field --if you turned off the trapping field --would you get entangled hydrogen "en-masse"?
11:21:18 From Harry Forsdick to Everyone:
	Dr, Zwierlein:  I think it would be great to hear you talk about what is going on currently in your lab.  I think it would be good to wait a little bit for us to absorb what you said today until you would explain what is currently going on in your group.
11:23:36 From Judy & Mike Alexander to Everyone:
	In frequency doubling, where high irradiation produces two photons, the photons are correlated.  That's fairly common in nonlinear optics.
11:29:10 From Bob Melanson to Everyone:
	Is it possible to disentangle two particles entangled "close" together in time and space?  Then, Is it possible to entangle two particles at a distance?  Then, Can these particles be disentangled?
11:33:43 From Larry Wittig to Everyone:

11:38:04 From Mark Edelman to Everyone:
	So the next question would be: can you have multiple different types of entanglement of the same particles? And can just one disentanglement occur then?
11:39:26 From Tony Galaitsis to Everyone:
	If you “measure” the properties of particle 1 in World 1, how do you know where “World 2” is?

	Who gets reported as a child abuser is also a function of which communities are willing to do the reporting.
11:15:39 From Bob Primak to Everyone:
	Automating a biased process only reinforces the bias.
11:15:55 From Judy & Mike Alexander to Everyone:
	The Allegheny case is one of asking the *wrong* question, not just "bias".
11:16:28 From Bob Primak to Everyone:
	They had all the answers, it was the questions they got wrong.
11:17:07 From Judy & Mike Alexander to Everyone:
	That is, I\Allegheny County assumed that the number of calls would reflect the occurrence or severity of child abuse.
11:19:21 From Bob Primak to Everyone:
	ChatGPT gave a computer user group an interesting experience with ChatGPT. IT told us that our organization disbanded in 2012!
11:19:30 From Bob Primak to Everyone:
	It, not IT.

	anything about Parker Solar Probe?
10:12:05 From Bob Primak to Everyone:
	It is true that the Apollo Engineering Drawings were lost or discarded.
10:15:48 From Bob Primak to Everyone:
	Correction -- NOT true. There was hardware not preserved, but the blueprints are still available online. https://www.quora.com/Did-NASA-lose-the-blueprint-plans-for-the-Apollo-spacecraft-How-and-why-What-about-some-of-the-the-videos-or-photos-of-the-Apollo-missions-Again-how-or-why
10:17:34 From Bob Primak to Everyone:
	Also, some of the backup recorded tapes were not preserved. Today's video enhancement technology might have been able to extract useful images from these backup tapes, but they are gone.
10:23:57 From Bob Primak to Everyone:
	Those were more than video. They were 14-track tape, which included telemetry data. Most likely they were erased and reused. https://www.nasa.gov/feature/not-unsolved-mysteries-the-lost-apollo-11-tapes
11:05:29 From Bob Primak to Everyone:
	SpaceX pricing and performance (speed) have been severely criticized by people who have tried the system so far.
11:07:13 From Judy & Mike Alexander to Everyone:
	The large number of satellites "up there" have, apparently, brightened the night sky, messing, among other things, with terrestrial astronomy.
11:09:39 From Bob Primak to Everyone:
	Not to mention contributing to overcrowding of LEO where Starlink is filling up available orbits.
11:10:33 From Bob Primak to Everyone:
	Early tests of Starlink latency have not been very impressive. But there is great potential in the system
11:16:28 From Larry Wittig to Everyone:
	Hollow core fiber optic cables transmit at very close to the speed of light.
11:27:08 From Bob Primak to Everyone:
	UAP -- Unidentified Aerial Phenomena.
11:27:55 From Carl Lazarus to Everyone:
	Maybe they are Chinese balloons.
11:28:33 From Bob Primak to Everyone:
	That farmer's photo is a known fake.
11:40:07 From Umesh Shelat to Everyone:
	Was his George’s father named Noah?

10:08:03 From Barry Kort to Everyone:
	Here is the blog post on Crypto-Currencies that I posted nearly a decade ago ~ http://moultonlava.blogspot.com/2013/11/mathematically-defined-crypto-currencies.html
10:11:14 From tedpk to Everyone:
	can you distinguish Bitcoin, Ethereum, etc from the Stable Coins such as DST, etc.
10:11:55 From Judy & Mike Alexander to Everyone:
	…… not beholden to government" :  Sounds like banking before the Federal Reserve system was created, Depression-era banking laws, ...
10:17:45 From Jerome Slate to Everyone:
	What is the purpose of mining coins for the cryptocurrency itself? Is it like the Federal Reserve printing money?
10:19:22 From Steve Isenberg to Everyone:
	Re: mining Bitcoin.  Yes. You are printing money (if you are lucky and are the first to “find a solution”)
10:19:56 From tedpk to Everyone:
	can you distinguish open and closed blockchain [e.g. IBM]
10:20:18 From Jerome Slate to Everyone:
	I understand how it helps the miner. How does it help the currency. When the Fed prints money, it debases the currency.
10:21:24 From Steve Isenberg to Everyone:
	Earning bitcoin by a successful “solution” is a reward for finding that solution.  This is not an issue for now, as the limit on number of bitcoin has not been reached.
10:22:16 From Steve Isenberg to Everyone:
	My stepson owns bitcoin that he earned from the efforts of his mining computers.
10:23:01 From Jerome Slate to Everyone:
	Does not answer my question. The question is on the benefit to the cryptocurrency, NOT the miner.
10:24:24 From Steve Isenberg to Everyone:
	When he earns bitcoin, it has no effect on the price of the bitcoin currency.
10:31:16 From Larry Wittig to Everyone:
	Now folks that lost bitcoin value are suing celebrities who recommended buying them.
10:36:28 From Larry Wittig to Everyone:
	Paul krugman (nyt economist) callls bitcoins a self occurring ponzi scheme with no useful purpose except to launder money.
10:37:23 From tedpk to Everyone:
	if you put $1,000 into Amazon about 20 years ago ==> you are a millionaire today
10:47:14 From Steve Isenberg to Everyone:
	To explore Bitcoin Blockchain (and also other cryptos) visit https://www.blockchain.com/explorer/assets/btc — this is what Bob was showing earlier.

	Trust, but verify (Russian: Доверяй, но проверяй, tr. Doveryay, no proveryay, IPA: [dəvʲɪˈrʲæj no prəvʲɪˈrʲæj])
10:51:29 From Larry Wittig to Everyone:
	Please comment on if taxes are due on crypo earnings.
10:55:25 From Steve Isenberg to Everyone:
	There is a machine (like a candy machine) in Burlington Mall that you can buy/sell Bitcoin.
11:05:16 From tedpk to Everyone:
	These things can happen on the Alberta Exchange for Junior Capital Pools -- originally used to fund mining or drilling
11:12:35 From tedpk to Everyone:
	you miss ID'd the SNP & Coins
11:15:53 From Judy & Mike Alexander to Everyone:
	If you want to make an analogy for Bitcoin et al., it might be "investing" in real currencies (dollars,pounds, etc.)
11:25:30 From Jerome Slate to Everyone:
	Old expression: "A fool and his money are soon parted."      Plus ca change, plus c'est la meme chose.

10:27:32 From Jerome Slate to Everyone:
	Will gravity pull light that is approaching, thus increasing its speed?
10:33:14 From Larry Wittig to Everyone:
	Are thercase where a black hole causes the lensings and you get a ring without the bright center?
10:48:55 From Adam Broun to Everyone:
	Does gravitational lensing produce any chromatic dispersion? (i.e. different effective refraction for different light wavelengths)?

	Name:  Einstein Ring, Hon.
11:24:25 From Tony Galaitsis to Everyone:
	Question about separated source-lens objects…
11:25:58 From Ken Cutter to Everyone:
	can a "normal" image of the source be constructed from the rings?

07:19:37 From tedpk to Everyone:
	Do you have a 'Hall of Fame"?  for your historical figures
07:20:11 From tedpk to Everyone:
	Where is Marie Curie?
07:22:01 From tedpk to Everyone:
	She had to overcome more than most anyone ever to get where she got and then --  she got to the very top
07:25:02 From tedpk to Everyone:
	What is the distribution between Theory and  Experiment?
07:32:22 From tedpk to Everyone:
	Ada
07:32:37 From Barry Kort to Everyone:
	Yes. Ada Lovelace.
07:32:45 From Bob Primak to Everyone:
	Ada Lovelace, to be exact.
07:35:18 From Judy & Mike Alexander to Everyone:
	IBM-style punch cards came long after the Analytical Engine.  See Hollerith.
07:37:42 From Carl Lazarus to Everyone:
	Ada had the insight that numbers in a computer could be used to represent any kind of non-numeric information, such as text or music.
07:40:08 From tedpk to Everyone:
	Jaquard Weaving Engine  -- was the source of the use of cards?
07:40:36 From Carl Lazarus to Everyone:
	I believe so.
07:43:17 From Bob Primak to Everyone:
	The Jacquard Looms used belts made of leather, with holes punched in them to create patterns in the weaving. This differs form programming more general=purpose computers, and it was not a direct source of modern computer punch cards.
07:45:43 From tedpk to Everyone:
	A number of years ago I wrote an editorial for the IEEE Boston Section -- There seems to be a bias to "lack of hands-on"
07:47:34 From tedpk to Everyone:
	Somewhat later I travelled to India presenting a workshop on Computer Engineering using PSOC tech -- there were many women but almost all had never handled a piece of computer hardware
07:52:02 From Dan Silber to Everyone:
	In 1969, I had a summer job supporting a computer programming group for a major insurance company in New York City. I was surprised to find it was mostly women, but I figured it was because it was a new field, unencumbered with the traditions of civil or mechanical engineering.
07:54:07 From Harry Forsdick to Everyone:
	Please confine your comments and questions to the chat.  We will make sure they get asked if they are relevant.
08:01:02 From Judy & Mike Alexander to Everyone:
	Science of cooking actually is a rather old idea.  My mother-in-law was a home ec major at Simmons College (graduated around 1941).  Her course of study had quite a lot of emphasis on the chemistry that occurs during cooking.
08:24:36 From Harry Forsdick to Everyone:
	To those who arrived after the meeting began please realize that the video projector that belongs to the LexCC is not working today.  Since we can’t control the computers all of the equipment that picks up sound is not working today.
08:25:59 From tedpk to Everyone:
	Karen Paneta @ Tufts?
08:29:42 From Barry Kort to Everyone:
	Also, have you done anything with Rosalind Picard (Affective Computing) at the MIT Media Lab?
