 Bizarre New Theorem of Pythagoras!

Chris Vuille

January 25, 2020

Figure 1: Distance from A to B

“The Square of the Hypotenuse is Equal to the Sum of the Squares

of the Legs.”

The theorem of Pythagoras gives the distance between two points. In a plane,

it is given by

∆s

2 = ∆x

2 + ∆y

2

(1)

where ∆s is the length of the hypotenuse and also the distance between the two

points, and ∆x and ∆y are the displacements, also called the legs of the triangle.

In the figure, the distance from point A to point B is

∆s

2 = 42 + 32 = 25 → ∆s =

√

25 = 5 (2)

Of course this number has units, so if the units were meters, you would say the distance is 5 meters.

In my theory, the theorem of Pythagoras is given by

∆s

2 = ∆x

2 + ∆y

2 + ∆x + ∆y + ∆N (3)

where N is some number. It is not associated with a direction, it’s just there! The number can change from point to

point, but it is not a displacement, like ∆s, ∆x, or ∆y. Now we compute the distance between two points. In today’s

universe, N changes very little from point to point, so ∆N is a very small number, call it .

∆s

2 = 42 + 32 + 4 + 3 +  = 32 +  → ∆s =

√

32 +  (4)

So the distance is now a little bit larger than 5.657 meters. While ∆N is usually a very small quantity, it could play roles

at the beginning of the universe or in black holes, and other contexts. It can be considered an effect of quantum mechanics.

∆x and ∆y turn out to be related to electric and magnetic fields. ∆x

2 and ∆y

2 are related to gravity, especially Einstein’s

theory of general relativity.

The theory in reality doesn’t look that much different from this. The distance function is infinitesimal because it has to

change from point to point. For example, ∆x becomes dx and ∆s becomes ds. That just means a displacement becomes

very tiny, so you can do calculus on it. It also includes another space dimension, and a time dimension. It might take the

form:

ds2 = −c

2

e

ν

dt2 + e

λ

dx2 + dy2 + dz2

+ Adt + Bdx + Cdy + Ddz + N (5)

Here, the quantities e

ν

, e

λ

, A, B, C, D all change as you go from location to location. N is the number function that also

changes as you go from location to location. The first part, through the dz term, is general relativity. The Adt+....+DdZ

term is electromagnetism, and N is the quantum contribution. You end up getting all kinds of numbers for a “distance”

that seem warped and nutty.

See? Completely whacko! That’s what I think the universe is!

stewart pollens dendrochronology

 Dendrochronology: Tool of Truth or Deception

by Stewart Pollens

Dendrochronology, which may be defined as the dating of the year-rings of wood, has only recently been employed in the dating of violins. In 1953, Lottermoser and Meyer attempted a relative dating of Italian stringed instruments by comparing the year-ring patterns of three violins, though actual dating was not achieved until the 1980s by Corona, Schweingruber, and Klein [1]. In 1994, when I curated The Violin Masterpieces of Guarneri del Gesù exhibition at the Metropolitan Museum of Art in New York, I invited one of the world’s leading dendrochronologists, Dr. Peter Klein of the Ordinariat für Holzbiologie of the University of Hamburg, to date the spruce tops of the twenty-five violins assembled for that exhibition. Among the conclusions gleaned from Klein’s findings are that Giuseppe Guarneri apparently did not use well-aged wood in making his instruments (the last datable ring is often just a few years earlier than the date on the violin’s label) and that he occasionally used mismatched pieces for the tops (whether this was by design, disinterest, or carelessness remains a matter of conjecture).

I met Dr. Klein many years before the Guarneri exhibition, for in the 1980s and 1990s, he was often invited to the Metropolitan Museum of Art to date panel paintings and other wooden objects. In dating musical instruments for the Department of Musical Instruments (including violins, viols, lutes, guitars, and harpsichords), I never had any reason to question his findings, which were always in agreement with my assessments regarding age and attribution. A few years after the Guarneri exhibition, I employed his services in dating the wood used to make the “Messiah” violin. Though he initially determined that the last datable year-ring of that instrument was 1738 (which postdated the violin's putative date of 1716 as well as Stradivari’s death in 1737), members of the violin trade maneuvered him into temporarily retracting his findings in exchange for an opportunity to re-measure the “Messiah’s” year-rings at the Ashmolean Museum. However, because of a dispute that developed during that session, he was unable to leave the Ashmolean with his measurements. Klein now declines to date violins, which is a great loss to those of us who formerly relied upon his expertise and objectivity. (Prior to publishing Klein’s results [2], I submitted the raw data to Dr. Peter Ian Kuniholm, a dendrochronologist on the faculty of Cornell University, who confirmed Dr. Klein’s dating.)

 

Following Klein’s controversial dating of the “Messiah,” Mr. John Topham, and subsequently, Dr. Henri Grissino-Mayer entered the fray and claimed to have found an earlier date that re-established the “Messiah’s” authenticity. Lacking Klein’s proprietary master chronology, Topham and Grissino-Mayer employed what they termed a “floating chronology,” which was derived from year-ring measurements taken from the “Archinto” and “Kux-Castelbarco” Stradivari violas. Unfortunately, their floating chronology only extended to 1685, and as dendrochronologists Angelo Mondino and Matteo Avalle later pointed out, this did not permit Topham and Grissino-Mayer to discover a more compelling statistical match further along in time [3].  In 2005 Mondino and Avalle asserted that the last year-ring of the “Messiah” grew in 1788, fifty-one years after the death of Antonio Stradivari, though in a more recent study, they claim to have discovered an even later date, 1844 [4].   

 

Disturbed by the multitude of conflicting dates, I decided to delve more deeply and directly into this dating technique in the hope of learning more about it and, perhaps, determine why dendrochronologists have arrived at so many different dates for the “Messiah.” In 2007 I purchased the Synchro Search computer program and the accompanying Manual of Dendrochronology Applied to the Dating of Musical Instruments written by Angelo Mondino and Matteo Avalle (Cremona Books, 2005). Synchro Search is a graphing and statistical program for comparing year-ring data with established master spruce chronologies. The program disk includes a number of master chronologies that are in the public domain, including the Ötztal-Obergurgler, Siebenlist-Kerner Ötztaler, Obersaxon-Meierhof, Schweingruber, and Malcolm chronologies, which are among the chronologies that have been used in dating violins. In using the Synchro Search program, the graphed year-ring dimensions of the violin in question can be advanced with the click of a computer key against graphs of any of the master chronologies until a match is found.  The program automatically computes statistical data, including Gleichläufigkeit (similarity or G index), Pearson’s r correlation coefficient (see below), Student’s t, mean sensitivity, serial correlation coefficient, overlapping index, and linear regression. The program can also be set so that the computer will locate the best matches, which is very convenient when master chronologies are hundreds of years in length.

 

In my investigation of this dating procedure, I did not wish to muddy the “Messiah” waters any further, so I decided to use Synchro Search in an attempt to establish the age of a large (17½”; 444 mm) viola, apparently Brescian, that the late Jacques Francais attributed to Gasparo da Salò (1540-1609).  Making year-ring measurements of an old, heavily restored violin or viola top can be difficult.  There may be “patches coming through” made with transplanted or later wood, painted year-rings, as well as dents, scratches, and heavily discolored or retouched varnish that obscure the grain. One must be aware of seams, wings, and grain direction.  If even a single year-ring is missed, this can prevent the discovery of a match with the master chronology, so one must be very careful in measuring.  When visiting museums to measure violins and other musical instruments, Klein used a little 7X loupe fitted with a metric scale that came in contact with the surface of the instrument. The advantage of this device is that it can be carried around in a pocket; the disadvantage is that it must be pushed along the surface of the instrument as one moves from year-ring to year-ring. When using a loupe, it is necessary to call out the measurements to a recording secretary, and this is another inconvenience. I devised a piece of equipment that is more accurate and convenient to use, though unfortunately, it is cumbersome. It consists of a low-power stereo microscope with one eyepiece fitted with a cross-hair reticule. Below the microscope, a violin/viola cradle is attached to a 250 mm rack-and-pinion linear translation stage that is linked via a brass angle bracket to a 12”-300 mm linear scale with SPC output. To use this device, I clamp the instrument (with its strings, bridge, and tailpiece removed) in the cradle and start by aligning the earliest year-ring (which is typically the ring at the edge of the lower bout of the instrument—though one should carefully check the year-ring shading to make certain of the orientation) with the cross hair in the microscope’s eyepiece. Using the rack-and-pinion of the translation stage, I then carefully align the next year-ring against the cross hair and press the button on the linear scale’s output device. This enters the measurement into a Microsoft Excel spreadsheet, which I have programmed to subtract the previous measurement from the last one entered, so that I wind up with a column of year-ring widths. Most violins have tops made with book-matched slabs of spruce, so one must stop at the center joint. These tabulated widths should then be multiplied by a factor of 100 so that the graphed data can be more readily compared to the master chronologies (dendrochronologists work in units of 1/100 mm, so 1 mm is expressed as 100) [5]. The column of figures must then be copied out of Excel as a text file (.txt file extension) so that the data can be compared against any of the master chronologies that are supplied with the Synchro Search program.

 

Returning to the Brescian viola: I compared my 74 measurements of year-rings from the treble side of the instrument to the following master chronologies: PCAB Giertz Obergurgler 1276-1974, LADE Siebenlist Obergurgler 1511-1974, PCAB Schweingruber Obersaxen 1537-1995, and Media 46° 1276-1994. I employed a statistical test termed Gleichläufigkeit (G index or similarity), initially with 60% agreement (which represents a degree of probability of 95%) between the year-rings of the viola and a master chronology, because this percentage of agreement is frequently considered a match in dendrochronological reports and literature[6]. The reader may be surprised by the number of “matches” that were found:

Fifty-two matches were found at 60% Gleichläufigkeit or higher, and 13 matches were found at 65% Gleichläufigkeit or higher (representing a degree of probability of around 99% or better). It is also disconcerting that the PCAB Giertz Obergurgler, LADE Siebenlist Obergurgler, and PCAB Schweingruber Obersaxen master chronologies produced very few dates in common (1732 and 1756); the Media 46° chronology exhibited several concordances (1522, 1572, 1665, 1732, and 1756), but this would be expected as it is a composite derived from over thirty chronologies, including the other three that I used. The 1657 date (which has the highest Gleichläufigkeit of 70.5% and a probability of 99.9%) is of interest because violas of this large size were still being constructed at this time, though if correct, it would rule out Gasparo da Salo as the maker, as he died in 1609. However, I should point out that I subsequently discovered a date of 1805 with a considerably higher Gleichläufigkeit of 75.3% using the CEBR Schweingruber Ceader Valley (Cipro) chronology. I must admit that I did not initially seek a match with this master chronology because its synchronization dates extend only from 1675 through 1981, and my inclination was to search for dates using master chronologies that had earlier starting points. This only demonstrates that one may inadvertently overlook a master chronology because its inclusive years would appear to fall outside the date that one hopes or expects to find.   

 

In general, my experiences with the Alpine master chronologies supplied with the Synchro Search program (which include the PCAB Siebenlist-Kerner Ötztaler and PCAB Gierz Obergurgler chronologies that were employed by Grissino-Mayer, et. al., in fixing a date to their floating chronology when attempting to date the “Messiah”) have not yielded overwhelmingly convincing, or unique matches with a number of Italian instruments that I have attempted to date [7]. The reason for this may be due to the fact that these master chronologies were constructed from wood samples taken from Alpine regions or altitudes that do not have precisely the same climatic conditions as the locale where the Cremonese and Brescian makers obtained their wood, which I believe was likely from the Italian Alps directly north of Brescia. Many of the master chronologies in the public domain are derived from wood found in the Ötztal and Obergurgl mountain ranges, which are close to Innsbruck, Austria. It is also possible that the Synchro Search program itself is at fault--some dendrochronologists have been critical of certain of its statistical operations, including its method of calculating Pearson’s r correlation coefficient and Student’s t [8].  However, determining Gleichläufigkeit is fairly straightforward, and it is often the only measurement cited in dendrochronological reports, including those of Peter Klein. Yet another reason for the failure to discover singular matches may be due to an underlying flaw in the technique itself—that it is simply not precise enough to pin irrefutable dates on relatively short sequences of year-rings. 

​

In conclusion, I would strongly advise violin historians, authenticators, appraisers, and purchasers to be wary of the dendrochronology dates that are being published in auction catalogs, certificates, and scholarly journals. I would also suggest that dendrochronologists produce reports that include raw data and statistical details, and if they arrive at several possible dates for an instrument, they should report all of them; moreover, they must never rule out dates that they have been prompted to believe lie outside the probable period of manufacture.

THIS IS WHERE REUTERS STANDS RIGHT BEHIND THE NYT MAKING W EUROPEAN AMERICAN HISTORY ONLY ABOUT ENSLAVING NEGROES AND NOTHING ELSE

 

By Sharon Kimathi, Energy and ESG Editor, Reuters Digital Hello!   United States leaders – lawmakers, presidents, governors and justices – have slaveholding ancestors, a Reuters examination found. Few are willing to talk about their ties to America's “original sin” and the below will highlight some key findings from the report.   But how is slavery tied to environment, social and governance (ESG) issues? The United Nations Special Rapporteur on contemporary forms of racism, racial discrimination, xenophobia and related intolerance, E. Tendayi Achiume, said it best in a U.N. report.   “There can be no meaningful mitigation or resolution of the global ecological crisis without specific action to address systemic racism, in particular the historic and contemporary racial legacies of colonialism and slavery.”   In researching the genealogies of America’s political elite, a Reuters examination found that a fifth of the nation’s congressmen, living presidents, Supreme Court justices and governors are direct descendants of ancestors who enslaved Black people.

Among 536 members of the last sitting Congress, Reuters determined at least 100 descended from slaveholders. Of that group, more than a quarter of the Senate – 28 members – can trace their families to at least one slaveholder.   Those lawmakers from the 117th session of Congress are Democrats and Republicans alike. They include some of the most influential politicians in America: Republican senators Mitch McConnell, Lindsey Graham, Tom Cotton and James Lankford, and Democrats Elizabeth Warren, Tammy Duckworth, Jeanne Shaheen and Maggie Hassan.   In addition, President Joe Biden and every living former U.S. president – except Donald Trump – are direct descendants of slaveholders: Jimmy Carter, George W. Bush, Bill Clinton and – through his white mother’s side – Barack Obama. Trump’s ancestors came to America after slavery was abolished.

In notifying political elites of their family ties to slaveholding, Reuters investigators identified which of their ancestors enslaved people, how many people that ancestor enslaved, and how many generations removed that ancestor is from them. Reuters also sought comment from each public official to understand how learning about their family connection to slavery might affect them personally, and whether that knowledge might inform their views on policy matters.   “Before you reached out, I didn’t know this part of my genealogy. I’ve always been adamant that we fully reckon with our country’s history, from the extraordinary horrors of slavery to forced boarding schools for Native children to Jim Crow segregation,” said U.S Democratic Senator for New Mexico Martin Heinrich in a statement to Reuters.   “And I’ve been proud to fight for reforms in the Senate that address ongoing systemic racism and injustices. But knowing that my own ancestor enslaved 12 people makes this work even more personal. We have so much more work to do, and I will never walk away from doing it.”   Bills introduced in the House and Senate would create a commission to address “the fundamental injustice, cruelty, brutality, and inhumanity of slavery in the United States and the 13 American colonies between 1619 and 1865” – and the racial and economic discrimination against Black Americans that followed.   Such a commission, the bills say, would consider a national apology and proposals for reparations.   Some of the leading voices on the matter, both for and against, have a personal connection to the issue: They have one or more ancestors who were slaveholders.   The issue is divisive. A Reuters/Ipsos survey found that slightly more than half of respondents identifying as Democrats – 58% – support reparations. Just 18% of Republicans do. The divide is even greater between Black and white America. The poll found that 74% of Black Americans favor reparations compared to just 26% of white Americans.   In conjunction with this Reuters series, Legacy Family Tree Webinars is making available at no charge a variety of online genealogy webinars from its extensive library to help novices and experts alike.

Talking Points

Comment: A federal appeals court in Louisiana decided that a cop can sue a protest organizer for injuries caused by another person during a demonstration, ratifying a novel legal theory that threatens to further suppress protests and First Amendment rights more broadly. “The appeals court, to my mind, ignores the central role of civil disobedience — demonstrations that are peaceful, and sometimes unlawful — in securing our most fundamental American rights,” writes Hassan Kanu. People with disabilities in Spain and other European countries have been disproportionately affected by unprecedented heat extremes, a leading human rights watchdog said, urging authorities to provide adequate support. Britain's plan to send asylum seekers to Rwanda will cost 169,000 pounds ($215,035) per person, according to the first detailed government assessment of a high-stakes promise to tackle record numbers of people arriving in small boats. The European Union will call on countries to prepare for "spillover" effects from increased climate change-driven conflicts, according to a draft document, and warn of the need to assess new risks posed by large-scale technological interventions that alter the climate as a potential route to tackle global warming. Companies will face more pressure to disclose how climate change affects their business under a new set of G20-backed global rules aimed at helping regulators crack down on greenwashing. In the Market: Corporate directors, academics and other governance experts are calling for companies to focus more on retaining and nurturing the people they hire. Among the components of DEI - diversity, equity and inclusion - they argue a focus on the latter two themes is crucial to make diversity more than just a box-checking exercise and necessary to reap its benefits.

In Conversation

Carolynn Johnson, CEO of U.S.-based diversity, equity and inclusion ranking firm DiversityInc, shares her thoughts on the pushback against using ‘ESG’ and data transparency in DEI:   “It’s interesting to me that we will allow others to edit us on what to call it.   “Nobody is talking about ‘revenue’ and changing that. Nobody is talking about ‘profitability’ and then saying we have to call it something else. No one is talking about ‘sales’ and saying change that. But when it comes to treating people fairly and ESG, we're allowing ourselves to be edited on telling the truth and I have a problem with that.   “This is why the gateway to any organization working with us or receiving recognition with us as a Top 50 company for diversity is through data transparency.   “Are companies being forthright about their data? This year, there were 151 major U.S. employers with 750 full-time equivalent employees or more (that's one of the criteria to be eligible).    "These rankings represent evidence-based, superior human capital outcomes that are achieved only by data transparency and an unwavering commitment to workplace fairness for everyone.   “I truly do believe that most of them do believe in this work. They do believe that everyone is equally valued and are deserving of equal opportunity, and they may get it wrong, but nobody is perfect.   “It’s about the desire to keep trying and to communicate that effort that I think deserves recognition to show that they're all doing much better than any other organizations.”
