It's stuff like this that makes me love archaeology. Turns out, we can trace the concept of math homework back to at least 2300 B.C.E., in ancient Mesopotamia.

In the early 20th century, German researchers found several clay tablets at the site of Šuruppak. (Today, that's basically the Iraqi city of Tell Fara.) Some of the tablets appear to be the remains of math instruction, including two different tablets that are working the same story problem.

A loose translation of the problem is: A granary. Each man receives 7 sila of grain. How many men? That is, the tablets concern a highly artificial problem and certainly present a mathematical exercise and not an archival document. The tablets give the statement of the problem and its answer (164571 men - expressed in the sexagesimal system S since we are counting men - with 3 sila left over). However, one of the tablets gives an incorrect solution. When analyzing these tablets, Marvin Powell commented famously that it was, "written by a bungler who did not know the front from the back of his tablet, did not know the difference between standard numerical notation and area notation, and succeeded in making half a dozen writing errors in as many lines."

That comes from a site set up by Duncan Mellville, a math professor at St. Lawrence University in Canton, NY. He's actually got a whole collection of essays on Mesopotamian mathematics. I am certain, that by posting this, I've just ruined somebody's productivity for, like, a week.

New research on trends in adult human height over the last century confirm that, no surprise, humans are getting taller overall due to better nutrition and disease control. However according to the health science group Non-Communicable Diseases Risk Factor Collaboration (NCD-RisC), the gain in adult height varies dramatically by country. From their paper, published in […]

Between April and July, Iran’s salty Lake Urmia changed from a bright green color to a blood red.

According to NASA, the periodic color change is caused by micro algae producing carotenoids that help with photosynthesis and act as […]

can anyone spot the doodles among the cuneiform?

Cuneiform doodles are actually quite common. Usually birds. Turns out it’s very easy to draw a bird with a reed on clay.

Ha, completely useless yet fun knowledge. Thanks. :)

There must have been a previous problem that established how big a granary is. The way the problem is stated on the tablet I can’t see how there’s enough information to solve it.

Of course, even with that information I don’t think I could solve it using the methods they expect. I suck at sexagesimal long division. Cinch in base ten though

I kind of got the impression that the capacity of a granary might have been more common knowledge then. Like how many pints are in a gallon or something.

Looks like it is 1152000 sila of grain. Which is 3840 gur of grain. In base 60 that’s 140, which seems equally as memorizably odd as the conversion factors for Imperial units.

“The way the problem is stated on the tablet I can’t see how there’s enough information to solve it.”

That never slowed down one of my math professors. :/

Very cool! Maggie finds the neatest stuff to post!

“Please be sure to use a No. 2 stylus.”

you ruined mine. Thanks, maggie!

And as Jimmy Buffet would say: Math still suks!

I’ve seen some tablets with math problems on them. They pop up whenever it’s the Yale Babylonian collection’s turn to put things in the display cases at the Sterling. Maybe next time I’ll take a photograph.

Marvin Powell commented famously that it was, “written by a bungler who did not know the front from the back of his tablet, did not know the difference between standard numerical notation and area notation, and succeeded in making half a dozen writing errors in as many lines.”

Mr. Powell, it’s easy for you to say since you’ve never inscribed anything on a stone tablet… the iPad of old days.

You know that tablet is clay, not stone, right, ibuyufo?

Yes, but stone tablets were the iPads of days gone by.

Only a week ago it was explained to us http://boingboing.net/2011/11/22/errol-morris-and-jfks-assass.html why it is silly to draw conclusions like this from incomplete information. There are millions of explanations for that translation, claiming it is “maths homework” is just a, probably incorrect, guess.

There may be multiple explanations but some are more probable than others. Given the evidence this is one of the more likely ones.

Show your work!

Some poor Sumerian kid’s secret fear that future archeologists will find their old homework and think they were stupid just came true.

Dr. Melville spells his name with three l’s, not four…but thanks for the mention!

Zuul ate my tablet…

I remember that episode of Superbook.

Yup. There goes my next week! Weeee!

OK, now I have to look up Sumerian sexagesimal cuneiform.

It’s stuff like this that makes me love archaeology. Turns out, we can trace the concept of math homework back to at least 2300 B.C.E., in ancient Mesopotamia.

Nice !

One of the best introductions to Mesopotamian Mathematics is Eleanor Robson’s Mathematics in Ancient Iraq: http://press.princeton.edu/titles/8834.html

You can find photographs of most of the tablets here: http://cdli.ucla.edu/

Thanks! Found ’em!

Here are the actual tablets:

I think the first one is “right”, but I’m not sure…
