The World’s Oldest Homework: A Look at Babylonian Math Homework from 4,000 Years Ago

Home­work has late­ly become unfash­ion­able, at least accord­ing to what I’ve heard from teach­ers in cer­tain parts of the Unit­ed States. That may com­pli­cate var­i­ous fair­ly long-stand­ing edu­ca­tion­al prac­tices, but it does­n’t nec­es­sar­i­ly reflect an absolute drop in stan­dards and expec­ta­tions. Those of us who went to school around the turn of the mil­len­ni­um may remem­ber feel­ing entombed in home­work, an inten­si­fied ver­sion of what the gen­er­a­tion that came of age amid the ear­ly Cold War’s pres­sure for “more sci­ence,” would have dealt with. But late baby boomers and ear­ly Gen-Xers in the six­ties and sev­en­ties had a much lighter load, as did the gen­er­a­tion edu­cat­ed under John Dewey’s reforms of the ear­ly twen­ti­eth cen­tu­ry.

We can fol­low this line all the way back to the times of the Baby­lo­ni­ans, 4,000 years ago. In the video above from her chan­nel Tibees, sci­ence YouTu­ber Toby Hendy shows us a few arti­facts of home­work from antiq­ui­ty and explains how to inter­pret them.

Inscribed in a clay tablet, their sim­ple but numer­ous marks reveal them to be exam­ples of math home­work, that most loathed cat­e­go­ry today, and per­haps then as well. (Even when inter­pret­ed in mod­ern lan­guage, the cal­cu­la­tions may seem unfa­mil­iar, per­formed as they are not in our base ten, but base 60 — shades of the “new math” to come much lat­er.) That the Baby­lo­ni­ans had fair­ly advanced math­e­mat­ics, which Hendy demon­strates using some clay of her own, may be as much of a sur­prise as the fact that they did home­work.

Not that they all did it. Uni­ver­sal school­ing itself dates only from the indus­tri­al age, and for the Baby­lo­ni­ans, indus­try was still a long way off. They did, how­ev­er, take the con­sid­er­able step of cre­at­ing civ­i­liza­tion, which they could­n’t have done with­out writ­ing. The ancient assign­ment Hendy shows would’ve been done by a stu­dent at an edu­ba, which she describes as a “scribe school.” Scribe, as we know, means one who writes — which, in Baby­lon, meant one who writes in Sumer­ian. That skill was trans­mit­ted through the net­work of edu­ba, or “house where tablets are passed out,” which were usu­al­ly locat­ed in pri­vate res­i­dences, and which turned out grad­u­ates lit­er­ate and numer­ate enough to keep the empire run­ning, at least until the sixth cen­tu­ry BC or so. From cer­tain destruc­tive forces, it seems, no amount of home­work can pro­tect a civ­i­liza­tion for­ev­er.

The World Record for the Shortest Math Article: 2 Words

In 2004, John Con­way and Alexan­der Soifer, both work­ing on math­e­mat­ics at Prince­ton Uni­ver­si­ty, sub­mit­ted to the Amer­i­can Math­e­mat­i­cal Month­ly what they believed was “a new world record in the num­ber of words in a [math] paper.”

Soifer explains: “On April 28, 2004 … I sub­mit­ted our paper that includ­ed just two words, ‘n2 + 2 can’ and our two draw­ings. [See one of them above.]” The sto­ry then con­tin­ues: “The Amer­i­can Math­e­mat­i­cal Month­ly was sur­prised, and did not know what to do about our new world record of a 2‑word arti­cle. Two days lat­er, on April 30, 2004, the Edi­to­r­i­al Assis­tant Mrs. Mar­garet Combs acknowl­edged the receipt of the paper”:

The Month­ly pub­lish­es expo­si­tion of math­e­mat­ics at many lev­els, and it con­tains arti­cles both long and short. Your arti­cle, how­ev­er, is a bit too short to be a good Month­ly arti­cle… A line or two of expla­na­tion would real­ly help.

Soifer writ­ers: “The same day at the cof­fee hour I asked John [Con­way], ‘What do you think?’ His answer was con­cise, ‘Do not give up too eas­i­ly.’ Accord­ing­ly, I replied [to] The Month­ly the same day”:

I respect­ful­ly dis­agree that a short paper in general—and this paper in particular—merely due to its size must be “a bit too short to be a good Month­ly arti­cle.” Is there a con­nec­tion between quan­ti­ty and qual­i­ty?… We have posed a fine (in our opin­ion) open prob­lem and report­ed two dis­tinct “behold-style” proofs of our advance on this prob­lem. What else is there to explain?

Soifer adds: “The Month­ly, appar­ent­ly felt out­gunned, for on May 4, 2004, the reply came from The Month­ly’s top gun, Edi­tor-in-Chief Bruce Pal­ka”:

The Month­ly pub­lish­es two types of papers: “arti­cles,” which are sub­stan­tive expos­i­to­ry papers rang­ing in length from about six to twen­ty-five pages, and “notes,” which are short­er, fre­quent­ly some­what more tech­ni­cal pieces (typ­i­cal­ly in the one-to-five page range). I can send your paper to the notes edi­tor if you wish, but I expect that he’ll not be inter­est­ed in it either because of its length and lack of any sub­stan­tial accom­pa­ny­ing text. The stan­dard way in which we use such short papers these days is as “boxed filler” on pages that would oth­er­wise con­tain a lot of the blank space that pub­lish­ers abhor. If you’d allow us to use your paper in that way, I’d be hap­py to pub­lish it.

Soifer con­cludes: “John Con­way and I accept­ed the ‘filler’, and in the Jan­u­ary 2005 issue our paper was pub­lished.” Vic­to­ry!

When John Nash wrote “Non-Coop­er­a­tive Games,” his Ph.D. dis­ser­ta­tion at Prince­ton in 1950, the text of his the­sis (read it online) was brief. It ran only 26 pages.

The Decimal Point Is 150 Years Older Than We Thought, Emerging in Renaissance Italy

His­to­ri­ans have long thought that the dec­i­mal point first came into use in 1593, when the Ger­man math­e­mati­cian Christo­pher Clav­ius wrote an astron­o­my text called Astro­labi­um. It turns out, how­ev­er, that the his­to­ry of the dec­i­mal point stretch­es back anoth­er 150 years–to the work of the Venet­ian mer­chant Gio­van­ni Bian­chi­ni. In his text Tab­u­lae pri­mi mobilis, writ­ten dur­ing the 1440s, Bian­chi­ni used the dec­i­mal point to cal­cu­late the coor­di­nates of plan­ets. In so doing, he invent­ed a sys­tem of dec­i­mal frac­tions, which, in turn, made the cal­cu­la­tions under­pin­ning mod­ern sci­ence more effi­cient and less com­plex, notes Sci­en­tif­ic Amer­i­can.

Glen Van Brum­me­len, a his­to­ri­an of math­e­mat­ics, recent­ly recount­ed to NPR how he dis­cov­ered Bian­chini’s inno­va­tion:

I was work­ing on the man­u­script of this astronomer, Gio­van­ni Bian­chi­ni. I saw the dots inside of a table — in a numer­i­cal table. And when he explained his cal­cu­la­tions, it became clear that what he was doing was exact­ly the same thing as we do with the dec­i­mal point. And I’m afraid I got rather excit­ed at that point. I grabbed my com­put­er, ran up and down the dorm hall­way look­ing for col­leagues who still had­n’t gone to bed, say­ing, this per­son­’s work­ing with the dec­i­mal point in the 1440s. I think they prob­a­bly thought I was crazy.

In a new arti­cle appear­ing in the jour­nal His­to­ria Math­e­mat­i­ca, Van Brum­me­len explains the his­tor­i­cal sig­nif­i­cance of the dec­i­mal point, and what this dis­cov­ery means for the his­tor­i­cal devel­op­ment of math­e­mat­ics. You can read it online.

A Retired Math Teacher Helps Students Learn Geometry Through Quilting

Some real talk from retired geom­e­try teacher Wendy Licht­man, above, the author of sev­er­al math-themed YA nov­els:

Not many 15-year-olds care that two par­al­lel lines are crossed by a trans­ver­sal.

“But right here are two par­al­lel lines,” she con­tin­ues, point­ing to a pink and orange quilt. “and these are trans­ver­sals, and they are at a 90º angle and it feels real. You’ve got­ta get it to look right.”

The teenaged par­tic­i­pants in the Oak­land, Cal­i­for­nia pro­gram she found­ed to demys­ti­fy geom­e­try through hands-on quilt­mak­ing get it to look right by plot­ting their designs on graph paper, care­ful­ly mea­sur­ing and cut­ting shapes from bright cal­i­co of their own choos­ing. (Lic­th­man has com­mit­ted to but­ton­ing her lip if their favored print is not to her taste.)

Licht­man came up with this cre­ative approach to help a bright stu­dent who was in dan­ger of not grad­u­at­ing, hav­ing flunked geom­e­try three times.

She details their jour­ney in How to Make a Geo­met­ric Quilt, an essay for­mat­ted as step-by-step instructions…not for quilt­mak­ing but rather how those in the teach­ing pro­fes­sion can lead with humil­i­ty and deter­mi­na­tion, while main­tain­ing good bound­aries.

Some high­lights:

6. Some­time after the sewing has begun, and the math note­book is ignored for weeks, begin to wor­ry that your stu­dent is not real­ly learn­ing geom­e­try.  She’s learn­ing sewing and she’s learn­ing to fix a bro­ken bob­bin, but real­ly, geom­e­try?

7. Remind your­self that this kid needs a quilt as much as she needs geom­e­try.

8. Remem­ber, also, the very, very old woman who taught you hat-mak­ing one night long ago.  She had gone to school only through 5th grade because, she said, she was a Black child in the deep south and that’s how it was back then.  Think about how she explained to the hat-mak­ing class that to fig­ure out the length of the hat’s brim, you need­ed to mea­sure from the cen­ter to the edge with a string and then do “three of those and a lit­tle bit more,” and remem­ber how you sat in awe, because three radii and a lit­tle bit more is the def­i­n­i­tion of pi, and this hat-mak­er had evi­dent­ly dis­cov­ered for her­self the for­mu­la for cir­cum­fer­ence.

As the two become bet­ter acquaint­ed, the stu­dent let her guard down, reveal­ing more about her sit­u­a­tion while they swapped sto­ries of their moth­ers.

But this was no easy A.

In addi­tion to expect­ing reg­u­lar, punc­tu­al atten­dance, Lict­man stip­u­lat­ed that in order to pass, the stu­dent could not give the fruits of her labor away.

(Sol­id advice for cre­ators of any craft project this ambi­tious. As Deb­bie Stoller, author of Stitch ‘n Bitch: The Knit­ter’s Hand­book coun­sels:

…those who have nev­er knit some­thing have no idea how much time it took. If you give some­one a sweater, they may think that you made that in an evening when you were watch­ing a half-hour sit­com. It’s only when peo­ple actu­al­ly attempt to knit that they final­ly get this real­iza­tion, this light bulb goes on over their heads, and they real­ize that, “Wow, this actu­al­ly takes some skill and some time. I’ve got new­found respect for my grand­ma.”)

Ulti­mate­ly, Licht­man con­cludes that the five cred­its she award­ed her stu­dent could not be reduced to some­thing as sim­ple as geom­e­try or quilt-mak­ing;

You are giv­ing her cred­it for some­thing less tan­gi­ble.  Some­thing like pride.  Five cred­it hours for feel­ing she can accom­plish some­thing hard that, okay, is slight­ly relat­ed to geom­e­try.

Exam­ples of the cur­rent cohort’s work can be seen on Rock Paper Scis­sors Col­lec­tive’s Insta­gram.

Once com­plet­ed, these quilts will be donat­ed to Bay Area fos­ter chil­dren and pedi­atric patients at the local Chil­dren’s Hos­pi­tal.

Why Algorithms Are Called Algorithms, and How It All Goes Back to the Medieval Persian Mathematician Muhammad al-Khwarizmi

In recent decades, a medieval Per­sian word has come to promi­nence in Eng­lish and oth­er major world lan­guages. Many of use it on a dai­ly basis, often while regard­ing the con­cept to which it refers as essen­tial­ly mys­te­ri­ous. The word is algo­rithm, whose roots go back to the ninth cen­tu­ry in mod­ern-day Greater Iran. There lived a poly­math by the name of Muham­mad ibn Musa al-Khwariz­mi, whom we now remem­ber for his achieve­ments in geog­ra­phy, astron­o­my, and math­e­mat­ics. In that last field, he was the first to define the prin­ci­ples of “reduc­ing” and “bal­anc­ing” equa­tions, a sub­ject all of us came to know in school as alge­bra (a name itself descend­ed from the Ara­bic al-jabr, or “com­ple­tion”).

Today, a good few of us have come to resent algo­rithms even more than alge­bra. This is per­haps because algo­rithms are most pop­u­lar­ly asso­ci­at­ed with the deep, unseen work­ings of the inter­net, a sys­tem with ever increas­ing influ­ence over the things we do, the infor­ma­tion we receive, and even the peo­ple with whom we asso­ciate.

Pro­vid­ed suf­fi­cient data about us and the lives we lead, so we’re giv­en to under­stand, these algo­rithms can make bet­ter deci­sions for us than we can make for our­selves. But what exact­ly are they? You can get one answer from “Why Algo­rithms Are Called Algo­rithms,” the BBC Ideas video at the top of the post.

For West­ern civ­i­liza­tion, al-Khwarizmi’s most impor­tant book was Con­cern­ing the Hin­du Art of Reck­on­ing, which was trans­lat­ed into Latin three cen­turies after its com­po­si­tion. Al-Khwarizmi’s Latinized name “Algo­rit­mi” gave rise to the word algo­ris­mus, which at first referred to the dec­i­mal num­ber sys­tem and much lat­er came to mean “a set of step-by-step rules for solv­ing a prob­lem.” It was Enig­ma code­break­er Alan Tur­ing who “worked out how, in the­o­ry, a machine could fol­low algo­rith­mic instruc­tions and solve com­plex math­e­mat­ics. This was the birth of the com­put­er age.” Now, much fur­ther into the com­put­er age, algo­rithms “are help­ing us to get from A to B, dri­ving inter­net search­es, mak­ing rec­om­men­da­tions of things for us to buy, watch, or share.”

The algo­rithm giveth, but the algo­rithm also taketh away — or so it some­times feels as we make our way deep­er into the twen­ty-first cen­tu­ry. In the oth­er BBC Ideas video just above, Jon Stroud makes an inves­ti­ga­tion into both the nature and the cur­rent uses of this math­e­mat­i­cal con­cept. The essen­tial job of an algo­rithm, as the experts explain to him, is that of pro­cess­ing data, these days often in large quan­ti­ties and of var­i­ous kinds, and increas­ing­ly with the aid of sophis­ti­cat­ed machine-learn­ing process­es. In mak­ing or influ­enc­ing choic­es humans would once have han­dled them­selves, algo­rithms do present a risk of “de-skilling” as we come to rely on their ser­vices. We all occa­sion­al­ly feel grat­i­tude for the bless­ings those ser­vices send our way, just as we all occa­sion­al­ly blame them for our dis­sat­is­fac­tions — mak­ing the algo­rithm, in oth­er words, into a thor­ough­ly mod­ern deity.

Bach on a Möbius Strip: Marcus du Sautoy Visualizes How Bach Used Math to Compose His Music

“A math­e­mati­cian’s favorite com­pos­er? Top of the list prob­a­bly comes Bach.” Thus speaks a reli­able source on the mat­ter: Oxford math­e­mati­cian Mar­cus du Sautoy in the Num­ber­phile video above. “Bach uses a lot of math­e­mat­i­cal tricks as a way of gen­er­at­ing music, so his music is high­ly com­plex,” but at its heart is “the use of math­e­mat­ics as a kind of short­cut to gen­er­ate extra­or­di­nar­i­ly com­plex music.” As a first exam­ple du Sautoy takes up the “Musi­cal Offer­ing,” and in par­tic­u­lar its “crab canon,” the genius of which has pre­vi­ous­ly been fea­tured here on Open Cul­ture.

Writ­ten out, Bach’s crab canon “looks like just one line of music.” But “what’s curi­ous is that when you get to the end of the music, there’s the lit­tle sym­bol you usu­al­ly begin a piece of music with.” This means that Bach wants the play­er of the piece to “play this for­wards and back­wards; he’s ask­ing you to start at the end and play it back­wards at the same time.” His com­po­si­tion thus becomes a two-voice piece made out of just one line of music going in both direc­tions. It’s the under­ly­ing math­e­mat­ics that make this, when played, more than just a trick but “some­thing beau­ti­ful­ly har­mon­ic and com­plex.”

To under­stand the crab canon or Bach’s oth­er math­e­mat­i­cal­ly shaped pieces, it helps to visu­al­ize them in uncon­ven­tion­al ways such as on a twist­ing Möbius strip, whose ends con­nect direct­ly to one anoth­er. “You can make a Möbius strip out of any piece of music,” says du Sautoy as he does so in the video. “The stun­ning thing is that when you then look at this piece of music” — that is the fifth canon from Bach’s Gold­berg Vari­a­tions — “the notes that are on one side are exact­ly the same notes as if this thing were see-through.” (Nat­u­ral­ly, he’s also pre­pared a see-through Bach Möbius strip for his view­ing audi­ence.)

In 2017 du Sautoy gave an Oxford Math­e­mat­ics Pub­lic Lec­ture on “the Sound of Sym­me­try and the Sym­me­try of Sound.” In it he dis­cuss­es sym­me­try as present in not just the Gold­berg Vari­a­tions but the twelve-tone rows com­posed in the 20th cen­tu­ry by Arnold Schoen­berg and even the very sound waves made by musi­cal instru­ments them­selves. Just this year, he col­lab­o­rat­ed with the Oxford Phil­har­mon­ic Orches­tra to deliv­er “Music & Maths: Baroque & Beyond,” a pre­sen­ta­tion that draws math­e­mat­i­cal con­nec­tions between the music, art, archi­tec­ture, and sci­ence going on in the 17th and 18th cen­turies. Bach has been dead for more than a quar­ter of a mil­len­ni­um, but the con­nec­tions embod­ied in his music still hold rev­e­la­tions for lis­ten­ers will­ing to hear them — or see them.
