A Brief History of Tally Sticks and Keeping Score

  

 Whenever you can, count.

~Sir Francis Galton

The traditional tally stick has a very long history. I have written about it before, but wanted to add some notes to make a somewhat more comprehensive inclusion of some other types of tally marks that have been (and some still are) in common use.

Roman natural philosopher Pliny the Elder described the best wood for tally sticks in his Naturalis Historia encyclopedia published circa C.E. 77. Venetian merchant traveler Marco Polo (1254–1324) reported that otherwise illiterate residents of Zardandan in the modern Chinese province of Yunnan recorded business transactions by cutting notches in each half of a split stick. On settling accounts the creditor’s half was returned to the debtor.

The term "tally" comes from the name of a stick or tablet on which counts were made to keep a count or a score. The Latin root is talea and is closely related to the origin of tailor, "one who cuts". Many math words have origins that reflect back to the earliest and most primitive uses of number. Compare the origins of compute, digit, and score.
Beads and knots on chord have also been used for tallys.  I am still looking for details on their use and will amend as I find more details.  *Wik

Around 1960 an ancient mathematical record on bone was uncovered in the African area of Ishango, near Lake Edward. While it was at first considered an ancient (9000 BC) tally stick, many now think it represents the oldest table of prime numbers.

The first record existing of tally marks is on a leg bone of a baboon dating prior to 30,000 BC. The bone has 29 clear notches in a row. It was discovered in a cave in Southern Africa. It is sometimes called the Lebombo Bone after the Lebombo mountains in which it was found. The exact age of such artifacts is a subject of debate, and their mathematical usage is somewhat speculative. Some sources have stated that the bone is a lunar phase counter, and by implication that African women were the first mathematicians since keeping track of menstrual cycles requires a lunar calendar.
Another candidate for the oldest tally record in history is a wolf bone found in Czechoslovakia with 57 deep notches cut into it, some of which appear to be grouped into sets of five.
For more on these early artifacts see Tally Sticks of the Stone Age by Andrej Kapcar 

The split tally was a technique which became common in medieval Europe, which was constantly short of money (coins) and predominantly illiterate, in order to record bilateral exchange and debts. A stick (squared hazelwood sticks were most common) was marked with a system of notches and then split lengthwise. This way the two halves both record the same notches and each party to the transaction received one half of the marked stick as proof. Later this technique was refined in various ways and became virtually tamper proof. One of the refinements was to make the two halves of the stick of different lengths. The longer part was called stock and was given to the party which had advanced money (or other items) to the receiver. The shorter portion of the stick was called foil and was given to the party which had received the funds or goods. Using this technique each of the parties had an identifiable record of the transaction. The natural irregularities in the surfaces of the tallies where they were split would mean that only the original two halves would fit back together perfectly, and so would verify that they were matching halves of the same transaction. *Wik

Several mathematical and business terms spring from the use of tally sticks.  It was the common practice that when a lperson deposited money with the Bank of England, and the tally stick was split, the lender would receive the heavier, or stock, end of the tally stick, while the Bank kept the "split".  The lender would "own the stock " of the Bank, To receive his money he would have to present the Talley to "Check" his stock.  

In Mathematics Galore by Budd and Sangwin, there is a story of much more recent tally sticks. It seems that until around 1828 the British kept tax and other records on wooden tally sticks. When the system was discontinued they were left with a huge residue of wooden tally sticks, so in 1834 they decided to have a bonfire to get rid of them. The bonfire was such a success that it burned the parliament buildings to the ground. What Guy Fawkes could not do with dynamite the Exchequer did with tally sticks.... The power of math.
The story, as improbable as it seems, is verified by a speech by Charles Dickens 1855. [Charles Dickens, Speech to the Administrative Reform Association, June 27, 1855, in Speeches of Charles Dickens, ed. K.F. Fielding, Oxford: The Clarendon Press, 1960, p. 206, ] The somewhat clipped version below is taken from Number, The Language of Science by Tobias Dantzig (pgs 23&24)

Ages ago a savage mode of keeping accounts on notched sticks was introduced into the Court of Exchequer and the accounts were kept much as Robinson Crusoe kept his calendar on the desert island. A multitude of accountants, bookkeepers, and actuaries were born and died... Still official routine inclined to those notched sticks as if they were pillars of the Constitution, and still the Exchequer accounts continued to be kept on certain splints of elm-wood called tallies. In the reign of George III an inquiry was made by some revolutionary spirit whether, pens, ink and paper, slates and pencils being in existence, this obstinate adherence to an obsolete custom ought to be continued, ..... All the red tape in the country grew redder at the bare mention of this bold and original conception, and it took until 1826 to get these sticks abolished. In 1834 it was found that there was a considerable accumulation of them; and the question then arose, what was to be done with such worn-out, worm-eaten, rotten old bits of wood? The sticks were housed in Westminster, and it would naturally occur ot any intelligent person that nothing could be easier than to allow them to be carried away for firewood by the miserable people who lived in that neighborhood. However, they never had been useful, and official routine required that they should never be, and so the order went out that they were to be privately and confidentially burned. It came to pass that they were burned in a stove in the House of Lords. The stove, over-gorged with these preposterous sticks, set fire to the paneling; the paneling set fire to the House of Commons; the two houses were reduced to ashes; architects were called in to build others; and we are now in the second million of the cost thereof.

Several images of the fire was painted by J.M.W. Turner who watched the fire from a boat on the Thames. I have a clip that I can not credit that says, "The fire of 1834 burned down most of the Palace of Westminster. The only part still remaining from 1097 is Westminster Hall. The buildings replacing the destroyed elements include Big Ben's tower (oooh, side bar... Big Ben is not the name of the tower at Westminster, it is the name of the great Bell in the Chimes there.. admit it, you did NOT know that, well at least I didn't till recently), with it's four 23 foot clock faces, built in a rich late gothic style that now form the Houses of Commons and the House of Lords. These magnificent buildings are still the subject of many paintings, including my own Parliament, with the grand Westminster Abbey on their north." The one below hangs in the  in a gallery in Cleveland, Ohio.

Thony Christie wrote to tell me that " Caroline Shenton (@dustshoveller) has written a new book about the burning down of the English parliament, "The Day Parliament Burned Down", which just won a prize as political book of the year 2012."  He also suggested two other changes which I have incorporated into this blog.

The split tally sticks shown above were common for two (and sometimes three ) person transactions, but there were unsplit tallys that represented records of receipts or other details.    A surviving talley from an English monastery recorded milk yields.  One from Sweden recorded the number of seals caught in a season. An Albanian talley recorded loaves of bread baked on successive dates.  



Many cultures use number symbols that reflect this tally counting approach for the lowest numbers. Japanese, for example, uses horizontal bars to represent the first three numerals.

The idea of creating tally sticks to record agreed amounts may be suggested by the Chinese character for contract, which shows the character for knife with the character for stick. (or so I am told by those who are better at reading Kanji than I)

The problem with the traditional tally mark, is that larger numbers start to become difficult to count. For example, try to quickly determine the number of casualties indicated by this sign I found at Wikipedia:


At some point methods were developed to counter this. Our word score for twenty (you know, four score and twenty years ago..) is believed to come from making a more distinct cross cut to ease the counting of large groups. The use of a slanted fifth mark across the first four in sets of five is also now common for these types of tallys. Today our most popular pastimes remind us of our mathematical beginnings as they report the sports "scores", the number of marks for each team.

James A Landau noticed something of a puzzle about the use of score. He writes, "I checked the Oxford English Dictionary, 2nd Edition and found that the first citation for "threescore" was in 1388, for "fourscore" was in 1250, and for "sixscore" was in 1300. There were no entries for twoscore, fivescore, sevenscore, eightscore, or ninescore, which is a little curious. Why would people only start counting by scores at 60 and quit after 120?"

There used to be a unit called a shock for groups of 3 score. The following quote comes from a post by John Conway. "Most of the major European languages had a break after 60, which usually had a special name of its own ; for example, it was a "shock" in English before it became "three score". In Elizabethan times, the standard names for 60,70,80,90 were "threescore", "threescore and ten", "fourscore" and "fourscore and ten" and the other European languages did much the same thing. The word shock as an amount persisted in American use (albeit in a slightly changed form) at least until 1919 when James Whitcomb Riley's poem, "When the Frost is on the Punkin" was published. The first line reads, "WHEN the frost is on the punkin and the fodder's in the shock," but by this time it seems that the bundles of corn stalks, bundled and dried to use for feed, or fodder, may not have reflected a count of sixty as much as however many could be conveniently bound together.

Other methods of tallying have appeared in different places. I figure most are newer, but their histories seem very hard to trace (If you have information on early use of any of the following, I would love to hear of them.)

Wikipedia has several representations such as the one below they credit to French and Spanish cultures.

I have never seen this, and don't know if it is still in common use any.where. ("Anyone, Anyone.") I did imagine almost instantly that it could be assembled into sets of four to make a score, or any number near a score by progressing in some order towards something like this, which I imagine could quickly be seen as 18:

I vacillated between whether the four diagonals in a rhombus or an X array would be better, but avoided the X because of its association with ten in Roman numerals and such.

The successive strokes of  the Chinese character for completion, or correct (it seems to have a variety of contextual applications) (East Asian tally marks 1 through 5) are used in China, Japan, and Korea to designate tallies in votes, scores, points, sushi orders, and the like, much as Tally b05.svg is used in Europe, Africa, Australia, and North America. Tallies beyond five are written with  for each group of five, followed by the remainder. For example, a tally of twelve 12 in tally marks as used in Europe, Zimbabwe, Australia, and North America is written as 正正丅. I have read that this method is traced back to the late Qing, early Republican period (around the end of the 19th Century).

John D Cook had some notes that included the tally marks shown below, which he credited to the mathematician/statistician John Tukey.   The method actually dates back to early use in the Forestry industry in the Americas as a method of keeping tallys.  My earliest notation is from  Forest mensuration By Carl Alwin Schenck, 1898 pg 47.


The final tally method I have seen comes from personal experience, and I can't find record of it anywhere.  It was a method my parents used to use in score keeping  in domino games.   The method they, and most others play, scores points in multiples of five, so the only method needed was how many multiples of five had been scored. Their method shows the first five points as a larger diagonal, / and the next five produces a large cross, X.  Afterwards they would proceed to fill in smaller slashes and x's in the four spaces around the first X. So that after 35 points (7 five point markers) the score would show something like this:
Since the game was played to 100 (or 20 five point scores) two of these completed would signal a win.
I have not seen this anywhere I have searched, but believe it must be pretty common, at least among domino players in the Southwest US.  If you are familiar with this and can give dates of recorded usage prior to about 1950, I would love that information also.
In the meantime, I will keep searching and updating as I get new information. 

I recently found a video that showed a similar score method, but allowed either an x or an o to represent 10 pts in the branches of the big X

Over Christmas vacation of 2021 I was also reminded of another common , I think, tally method for score-keeping in the card game of Euchre in which the two five cards are used to keep score.  Here Red has 7, Black has 3.



Another method using a two card and a three card that I found online, but never saw in my limited play experience.

As a footnote, Thony Christie wrote to tell me that " In German bars drinks are still tallied on the beer mats. "  I take this to be from his direct experience. "
----------------------------------------------------------------------------------------------------------------------------------------
In the fall of 2023 Jeannie and I were visiting Quebec City, and while walking through the old town, we came across Brousseau Inuit Art Gallery.  This was special for us as my Jeannie was descended from the Brusseau family of Michigan's western Upper Peninsula through her maternal grandfather, and to the Menominee Indian leader Big Martin through her maternal grandmother, so we were excited to visit.  It was a fantastic museum and I find it is one of the most incredible collections around.  But this is about tally marks and math, and sure enough, I found an intriguing set of marks on one of the carvings.  
I knew that indigenous people used tally marks for various reasons before the first Europeans arrived. The Powhatan kept their base-ten tallies on notched sticks and knotted strings. "They count no more but by tennes," Captain John Smith tells us, using words up to a hundred. They also had a word for thousand, but needed nothing beyond that. Keepers of calendar sticks are among the most exalted members of the Ojibway tribes, serving as shaman and sky watcher. Other sticks were used to keep track of the number of warriors slain in tribal wars, or the number of skins bartered in a fur trade.
While searching for more examples of Inuit tallys I came across an amazing story:"

A Number System Invented by Inuit Schoolchildren Will Make Its Silicon Valley Debut

It was a story in Scientific American, and the original goes deeper than I can, but I want to touch on this new tally based method of numeration with a base twenty syatem broken into base five units that was created working with inuit Children.  Their word for five is the word for arm, taliq, and the word for twenty represents the whole person, Iñuiññaq.  
The W may not differs only a little from the |||| in a regular tally before the slant across it makes a five (arm).
If you study the figures you can see how the zig-zag tallys build up. It's better for representing numbers than the basic tally, because you can represent multiple fives without the tallies for all the ones.  Look at the zig-zag for fifteen, for example.(Kids today, huh? What's the world coming to?)

 
Beads and knots as counters The earliest use of beads as counters may have been the development of prayer beads. Beads are among the earliest human ornaments and ostrich shell beads in Africa date to 10,000 BC. Over the centuries various cultures have made beads from a variety of materials from stone and shells to clay. How long they have been used to count prayers is unknown, but a Wikipedia site notes a statue of a holy Hindu man with beads dates to the 3rd century BC. The English word bead derives from the Old English noun bede which means a prayer.
Prayer beads is a little different, in my mind from typical tallys in that the object is not to record the number counted, but to count to a predetermined number without distracting the focus on the prayer or blessing. In some religions knotted ropes are used for the same purpose.

Beads on a string for calculating are described as early as the second century. These suanpan, or Chinese abacci are also not tallying devices in my mind, but more of a calculating device. However, others who have wasted part of their youth, as I did,  in older pool halls know that they frequently had beads on a wire string above the table to mark off the number of points scored for each player in certain games.  I saw a table top Foosball game with a similar device recently. But tallying with knots seems to have been in use in many cultures.

In the MAA Convergence online site, noted math historian Frank Swetz gives this description of the Inca use of knotted chords
Quipus were knotted tally cords used by the Inca Civilization of South America (1400-1560). The system consisted of a main cord from which a variable number of pendant cords were attached. Each pendant cord contained clusters of knots. These knots and their clusters conveyed numerical information. In some complex instances, further pendant cords were attached to these primary pendants. The number, type of knots, and knot and cluster spacing, as well as the pendant array, all conveyed particular information. A further dimension of this system was use of color: different pendants were dyed different colors, conveying different meanings. One of the few existing records of quipu use is found in the Chronicle of Good Government (1615/1616), written in Spanish by the Inca author Guaman Poma de Ayala.
These quipus may have been more of a recording device than a counting device, but Professor Swetz's use of "tally" in his description make me think they may well have had tally purposes as well.

Also, in The Number Concept by Levi Leonard Conant he tells of "Mom Cely, a Southern negro of unknown age, finds herself in debt to the storekeeper; and, unwilling to believe that the amount is as great as he represents, she proceeds to investigate the matter in her own peculiar way. She had 'kept a tally of these purchases by means of a string, in which she tied commemorative knots.'"

I have also seen several books for children that suggest that "counting ropes" were employed in the Navajo culture in the United States, but have no idea how historical these stories are. So at least it seems that counting ropes were used in some cultures for counting.

I am still searching for more evidence of their use, and welcome comments.

Everyone makes for himself a clear idea of the motion of a point, that is to say, of the motion of a corpuscle which one supposes to be infinitely small, and which one reduces by thought in some way to a mathematical point.

1657 Fermat made a challenge to the mathematicians of Europe and England. He posed two problems (in words rather than using notation as we shall do) involving S(n), the sum of the proper divisors of n:
1. Find a cube n such that n + S(n) is a square. (n + the sum of it's aliquot divisors, 7^3 is one solution, )
2. Find a square n such that n + S(n) is a cube.
We know that Frenicle found four solutions to the first of these problems on the day that he was given the problem, and found another six solutions the next day. He gave solutions to both problems in Solutio duorm problematum ... (1657).  In this work he posed some problems of his own, including the following:
Find an integer n such that S(n) = 5n, and S(5n) = 25n.
Find an integer n such that S(n) = 7n, and S(7n) = 49n.
Find n such that n3 - (n-1)3 is a cube.
Frenicle solved other problems posed by Fermat. For example he showed that if a right angled triangle has sides integers abc then its area bc/2 can never be a square. He also showed that the area of a right angled triangle is never twice a square. *SAU

1825 In 1824, the Rensselaer School was founded in Troy, N.Y., by Stephen van Rensselaer is the oldest continuously operating engineering college in the U.S. It opened on 3 Jan 1825, with the purpose of instructing persons, who may choose to apply themselves, in the application of science to the common purposes of life." The first class of 10 students graduated on 26 Apr 1826. The first director and senior professor was Amos Eaton who served from Nov 1824 - 10 May 1842. The name of Rensselaer Institute was adopted on 26 Apr 1832, and Rensselaer Polytechnic Institute on 8 Apr 1861.*TIS



1851 In the basement of his Paris home at the corner of rue de Vaugirard and rue d’Assas, Foucault first attempts to observe the turning of the earth on its axis with a pendulum. He mounts a 5 Kg bob on a two meter wire, and only observes the wire snap and the bob fall to the floor of the basement. Three days later he would try again, with much better results. *Amir Aczel, Pendulum, pg 5-7 (It seems that as early as 1661, Vincenzo Viviani, a student of Galileo had written, “we observe that all pendulums hanging on a single thread deviate from their initial vertical plane, and always in the same direction.” This document was discovered after Foucault’s results were released in an 1841 manuscript in the library of the Grand Duke of Tuscany.)



In 1919, Professor Ernest Rutherford succeeded in splitting the atom.

In 1970, a fireball was visible over a large area of the U.S. Midwest. The meteorite that fell was the first to be detected by the Prairie Network operated by the Smithsonian Institution's Astrophysical Observatory since 1964. Its path was photographed by two of the system's 16 cameras funded by a NASA grant. Using these records, scientists calculated the meteorite's impact point. Gunther Schwartz, field manager of the network found the 21.6-lb meteorite six days later within a half-mile of the predicted site, near the rural hamlet Lost City, about 45 miles east of Tulsa, OK. The fast retrieval enabled examination of radioactivity produced by the meteorite's exposure to cosmic rays, looking for clues to how the universe was created.*TIS




1970 Yuri Matiyasevich completes proof of Hilbert's 10th Problem.  Having been frustrated  by the problem, he had given up hope of solving it.  Asked to review an article by Julia Robinson, he was inspired by the novelty of her approach and went back to work on H10.  By Jan 3, 1970 he had a proof.  He would present the proof on January 29, 1970 



1977 Apple Computer Corporation is incorporated by Stephen Jobs and Stephen Wozniak. Its IPO, which took place three years later, was the largest one since the Ford Motor Company went public in 1956. The stock rose almost 32% that day giving the company a market valuation of $1.778 billion. Seven years later, on January 24, 1984, the company revealed the Macintosh personal computer in a publicity campaign that compared IBM with Big Brother and Apple as the savior of the masses.*CHM



1982 George Polya replies to a request that he explain what he knew about the commonly held belief in math circles that he and Hilbert had independently conjectured that the zeros of the Riemann zeta function correspond to the eigenvalues of a self-adjoint hermitian operator. He responded:
I can only tell you what happened to me.
I spent two years in Goettingen ending around the begin of 1914. I tried to learn analytic number theory from Landau. He asked me one day: "You know some physics. Do you know a physical reason that the Riemann hypothesis should be true." This would be the case, I answered, if the nontrivial zeros of the Xi-function were so connected with the physical problem that the Riemann hypothesis would be equivalent to the fact that all the eigenvalues of the physical problem are real.

I never published this remark, but somehow it became known and it is still remembered.

1986 Charon officially released as name of Pluto Moon, 7 1/2 years after it was proposed. Charon was originally known by the temporary designation S/1978 P 1, according to the then recently instituted convention. On June 24, 1978, U.S. Naval Observatory astronomer James Christy who had discovered the moon, first suggested the name Charon as a scientific-sounding version of his wife Charlene's nickname, "Char."
Although colleagues at the Naval Observatory proposed Persephone, Christy stuck with Charon after discovering it coincidentally refers to a Greek mythological figure: Charon is the ferryman of the dead, closely associated in myth with the god Hades, whom the Romans identified with their god Pluto. Official adoption of the name by the IAU waited until late 1985 and was announced on January 3, 1986.
There is minor debate over the preferred pronunciation of the name. The practice of following the classical pronunciation established for the mythological ferryman Charon is used by major English-language dictionaries such as the Merriam-Webster and Oxford English Dictionary. These indicate only one pronunciation of "Charon" when referring specifically to Pluto's moon: with an initial "k" sound. Speakers of languages other than English, and many English-speaking astronomers as well, follow this pronunciation.
However, Christy himself pronounced the ch in the moon's name as sh, after his wife Charlene. *Wik

2018 On this day it was announced that the Great Internet Mersenne Prime Search (GIMPS) has discovered the largest known prime number, 277,232,917-1, having 23,249,425 digits. A computer volunteered by Jonathan Pace made the find on December 26, 2017. Jonathan is one of thousands of volunteers using free GIMPS software available at www.mersenne.org/download/.  This means of course, there is a new largest perfect number.
At the time of discovery, Jonathan Pace was 51-year old. He lived in Germantown, Tennessee, and worked as a flight operations finance manager at FedEx.

He has loved mathematics since high school. He participated in GIMPS for 14 years prior to the discovery. He first became interested in searching for primes in 2003, when he read an article about the discovery of the 40th known Mersenne prime.

He discovered the Mersenne prime using a computer at his church. At the time of discovery, Pace was a deacon at the Germantown Church of Christ in Tennessee, where he built their desktops and handled the computer network administration. He installed Prime95 on one of the minister's computers and this computer found a Mersenne prime in six days of computation. This was just one of over a dozen machines Pace was using for the search.

1777 Louis Poinsot (1777–1859) was a French mathematician and physicist. Poinsot was the inventor of geometrical mechanics, showing how a system of forces acting on a rigid body could be resolved into a single force and a couple. The crater Poinsot on the Moon is named after him. A street in Paris is called Rue Poinsot (14th Arrondissement). When Gustave Eiffel built the famous tower, he included the names of 72 prominent French scientists on plaques around the first stage, Poinsot included. *Wik
He discovered four new regular polyhedra, two of which appear in Kepler's work of 1619 but Poinsot was unaware of this. *SAU and is a discoverer of star polyhedra.*VFR

1819 Charles Piazzi Smyth FRSE FRS FRAS FRSSA (3 January 1819, Naples, Italy – 21 February 1900), was Astronomer Royal for Scotland from 1846 to 1888, well known for many innovations in astronomy and his pyramidological and metrological studies of the Great Pyramid of Giza. *Wik

1906 William Wilson Morgan (3 Jan 1906, 21 Jun 1994) American astronomer who, in 1951, provided the first evidence that the Milky Way Galaxy has spiral arms. He spent his entire career at the Yerkes Observatory, including three years as director. Eschewing theory, his research was devoted to morphology, the classification of objects by their form and structure. With Keenan and Kellman, he introduced stellar luminosity classes and the two-dimensional classification of stellar spectra strictly based on the spectra themselves. With Osterbrock and Sharpless he demonstrated the existence of spiral arms in the Galaxy using precise distances of O and B stars obtained from spectral classifications. Morgan invented the UBV system of magnitudes and colors.*TIS




1917 Yurii Alekseevich Mitropolskiy (3 January 1917 — 14 June 2008) was a renowned Soviet, Ukrainian mathematician known for his contributions to the fields of dynamical systems and nonlinear oscillations.

DEATHS

1641 Jeremiah Horrocks (born c. 1617, 3 Jan 1641) English astronomer and clergyman who applied Johannes Kepler's laws of planetary motion to observations of the Moon and Venus. Once Horrocks managed to obtain a small telescope, his observations convinced him that Lansberg's tables were incorrect. He accepted Kepler's elliptical orbits, and in working on the moon he applied an elliptical orbit to it and established that the line of apsides precessed, an effect which he ascribed to the influence of the sun. Horrocks predicted and observed a transit of Venus on 24 Nov 1639, the first one ever observed, and from the observation he corrected the solar parallax, indicating a much greater distance of the sun than anyone before him had admitted. He died at age only 22.*TIS
According to local tradition in Much Hoole, he lived at Carr House, within the Bank Hall Estate, Bretherton. Carr House was a substantial property owned by the Stones family who were prosperous farmers and merchants, and Horrocks was probably a tutor for the Stones' children.
Horrocks was the first to demonstrate that the Moon moved in an elliptical path around the Earth, and he posited that comets followed elliptical orbits. He supported his theories by analogy to the motions of a conical pendulum, noting that after a plumb bob was drawn back and released it followed an elliptical path, and that its major axis rotated in the direction of revolution as did the apsides of the Moon's orbit. He anticipated Isaac Newton in suggesting the influence of the Sun as well as the Earth on the Moon's orbit. In the Principia Newton acknowledged Horrocks's work in relation to his theory of lunar motion. In the final months of his life Horrocks made detailed studies of tides in attempting to explain the nature of lunar causation of tidal movements.*Wik

1858 Henri-Philibert-Gaspard Darcy (10 Jun 1803, 3 Jan 1858) French hydraulic engineer who first derived the equation (now known as Darcy's law) that governs the laminar (nonturbulent) flow of fluids in homogeneous, porous media. In 1856, modern studies of groundwater began when Darcy was commissioned to develop a water-purification system for the city of Dijon, France. He constructed the first experimental apparatus to study the flow characteristics of water through the earth. From his experiments, he derived the Darcy's Law equation, describing the flow of water in nature, which is fundamental to understanding groundwater systems. He performed extensive tests on filtration and pipe resistance. He initiated the open-channel studies carried out by Bazin.*TIS

1891 John Casey (12 May 1820 in Coolattin, Kilbehenny, Co. Limerick, Ireland - 3 Jan 1891 in Dublin, IrelandCasey wrote over 25 research papers but his mathematical reputation rests on the six textbooks he wrote: A sequel to the first six books of the Elements of Euclid (1881; 8th ed. 1910); A treatise on the analytical geometry of the point, line, circle and conic sections (1885; 2nd ed. 1893); A treatise on elementary trigonometry (1886); A treatise on plane trigonometry (1888); A treatise on spherical trigonometry (1889). He also published his own edition of The first six books of the Elements of Euclid (1882; 17th ed. 1902) which is remarkable for its large store of exercises, collected and devised by himself and Richard Townsend, which occasioned the publication of a separate Key to the exercises of Casey's Elements of Euclid (1885) by Casey's son, Joseph. It was in his Sequel to Euclid (available at U of Mich) that Casey presented for the first time in a textbook those extensions of the theorems of Euclid that became known as the newer geometry of the triangle; indeed, he and the French mathematician Émile Lemoine (1840-1912) are held to be the founders of the so-called Modern Geometry of the circle and triangle. Casey's work was much appreciated in Belgium and France, and Professor Joseph Neuberg of Liège made substantial additions to later editions of Sequel to Euclid.*SAU





1892 Heinrich Eduard Schroeter (January 8th 1829 in Königsberg , January 3 1892 in Breslau ) was a German mathematician , who worked in synthetic geometry in the tradition of Jacob Steiner. *Wik

1908 Charles Augustus Young (15 Dec 1834, 3 Jan 1908) American astronomer who made the first observations of the flash spectrum of the Sun, proved the gaseous nature of the sun's corona and discovered the reversing layer of the solar atmosphere. He was a pioneer in the study of the spectrum of the sun and experimented in photographing solar prominences in full sunlight. On 22 Dec 1870, at the eclipse in Spain, he saw the lines of the solar spectrum all become bright for perhaps a second and a half (the "flash spectrum") and announced the "reversing layer." By exploring from the high altitude of Sherman, Wy. (1872), he more than doubled the number of bright lines he had observed in the chromosphere, By a comparison of observations, he concluded that magnetic conditions on the earth respond to solar disturbances.*TIS



1912 Jacob Amsler (16 Nov 1823 in Stalden bei Brugg, Switzerland - 3 Jan 1912 in Schaffhausen, Switzerland)worked on a problem which had quite a famous history. That was the problem of the attraction of an ellipsoid, which was first studied in depth by Ivory whose solution was later generalised by Poisson. Amsler extended the theorems of both Ivory and Poisson on this topic. It was a promising start to his research career in mathematical physics.
In 1854 Amsler married and this may have been the turning point in his career. His wife, Elsie Laffon, was the daughter of a well known Swiss scientist and, as was the custom in Switzerland at that time, he was known as Amsler-Laffon from this time on. Elsie and Jacob Amsler-Laffon's children were, however, always known by the name Amsler rather than Amsler-Laffon.
Shortly after his marriage Amsler changed his research interests and his career. He began to study the construction of precision mathematical instruments and quite quickly he had an idea for the design of a new type of planimeter. He invented the polar planimeter, a device for measuring areas enclosed by plane curves. It was based on polar coordinates whereas earlier instruments were based on cartesian coordinates. In 1856 Amsler published a paper Über das Planimeter in which he gave details of his idea. As Mahoney writes in , Amsler's planimeter, "... adapted easily to the determination of static and inertial moments and to the coefficients of Fourier series: it proved especially useful to shipbuilders and railway engineers. "
In order to make money from his invention, Amsler set up a workshop in Schaffhausen in 1854 specially designed to produce his polar planimeter. Three years later he had given up al his other interests to concentrate fully on producing instruments in the workshop. His shop produced 50 000 such instruments during his lifetime.
Amsler did not rest his fame on this single inspired idea but continued to invent new precision instruments. None of his other inventions came close to the polar planimeter in importance, but they were of sufficient quality to win him prizes at the world exhibition at Vienna in 1873, at Paris in 1881, and again in Paris in 1889. His brilliance was recognised with election to the Paris Académie des Sciences in 1892. *SAU




1920 Zygmunt Janiszewski, the father of Polish mathematics, died. At the end of World War I, Janiszewski was the driving force behind the creation of one of the strongest schools of mathematics in the world. This is all the more remarkable, given Poland's difficult situation at war's end.
Janiszewski devoted the family property that he had inherited from his father to charity and education. He also donated all the prize money that he received from mathematical awards and competitions to the education and development of young Polish students.
In mathematics, his main interest was topology.
He was the driving force, together with Wacław Sierpiński and Stefan Mazurkiewicz, behind the founding of the mathematics journal Fundamenta Mathematicae. Janiszewski proposed the name of the journal in 1919, though the first issue was published in 1920, after his death. It was his intent that the first issue comprise solely contributions by Polish mathematicians. It was Janiszewski's vision that Poland become a world leader in the field of mathematics—which she did in the interbellum.
His life was cut short by the influenza pandemic of 1918-19, which took his life at Lwów on 3 January 1920 at the age of 31. He willed his body for medical research, and his cranium for craniological study, desiring to be "useful after his death". *Wik



1927 Carl David Tolmé Runge (30 Aug 1856 in Bremen, Germany - 3 Jan 1927 in Göttingen, Germany) worked on a procedure for the numerical solution of algebraic equations and later studied the wavelengths of the spectral lines of elements. *SAU In numerical analysis, the Runge–Kutta methods that are named for him are an important family of implicit and explicit iterative methods for the approximation of solutions of ordinary differential equations. These techniques were developed around 1900 Runge and M.W. Kutta.*Wik When your regular walking partners include Felix Klein, David Hilbert, and Hermann Minkowski, you can't count on easily impressing them with your mental math skills, but it seems that Runge did so frequently. Once on their regular walks Klein brought up some departmental event that required them to know what date Easter would occur the next year. The group immediately turned to the idea of where they might acquire a calendar for the following year along the walk; all that is, except Runge who fell silent for a few yards, and then announced the date.




1967 Reginald Crundall Punnett (20 Jun 1875, 3 Jan 1967) English Mendelian geneticist who, with the English biologist William Bateson, were among the first English geneticists. They reported the discovery of two new genetic principles: the first account of genetic linkage in sweet pea; and gene interaction (1905). Punnett devised the "Punnett" square to depict the number and variety of genetic combinations. Punnett had a role in connecting Mendelism with statistics. In 1908, Punnett was asked at a lecture to explain, " if brown eyes were dominant, then why wasn't the whole country becoming brown-eyed?" Punnett in turn asked his friend the mathematician, G. H. Hardy. Out of this conversation came the Hardy-Weinberg Law which calculates how population affects genetic inheritance.*TIS

1989 Sergei Lvovich Sobolev (Russian: Серге́й Льво́вич Со́болев; 6 October 1908 – 3 January 1989) was a Soviet mathematician working in mathematical analysis and partial differential equations. He was born in St. Petersburg, and died in Moscow.*Wik

2011 Anatoliy Volodymyrovych Skorokhod (September 10, 1930 – January 3, 2011) was a Soviet and Ukrainian mathematician, and an academician of the National Academy of Sciences of Ukraine from 1985 to his death.
In 1956–1964 he worked at Kyiv University. From 1964 until 2002, he was at the Institute of Mathematics of the National Academy of Sciences of Ukraine. At the same time, he was a professor at Kyiv University. Since 1993, he had been a professor at Michigan State University, U.S., and a member of the American Academy of Arts and Sciences.
His scientific works are on the theory of stochastic differential equations, limit theorems of random processes, distributions in infinite-dimensional spaces, statistics of random processes and Markov processes.
Skorokhod is the author of more than 450 scientific works, including more than 40 monographs and books. *Wik

She Was Right ..... As Usual!

 I was taking my wife, Jeannie, junk shopping the other day on a cold crisp Kentucky morning.  I was under-dressed and shivering when she opened a stick of gum for herself and offered me one.  When I refused she informed me that chewing gum made you feel warmer. 

The next day I was reading a book my son gave me for Christmas, The Story Behind, The Extraordinary History Behind Ordinary Objects; and reading the section about gum, Bazooka gum by Topps, in particular, which was interestingly named for a little known instrument rather than a well known weapon.





I remembered my own childhood experiences with the gum and their penchant for bad jokes on their Bazooka Joe comic wrappers, such as ...."What do little men who lived under the bridge eat? ........Troll House Cookies."
This was a nice cubic chunk of chewable tasty gum that made super bubbles that cover half your face when your redneck friends would pop your giant bubble just as it was reaching world record proportions.   


But then Topps started putting baseball cards in and flattened the gum, it just wasn’t the same.  I grew out of buying gum and collecting cards long after it was common for us to pitch the gum with the wrapper.   In time I guess they just dropped the gum altogether. 

I came out of my reminiscences of childhood when I turned the page and found "A study at St. Lawrence University tested participants who chewed gum before and during testing, and participants who didn't chew anything, and they found those who chewed beforehand were able to recall information faster.  The researchers think cum chewing WARMS UP THE BRAIN to improve test scores..."  

I read the example to my wife and she simply responded with the wife's typical "And you thought you were Sooo Smart” look, leaning forward with hands spread ... reminding me that ...

She Was Right ..... As Usual!
