1680 – 1620 BC
Ahmes, sometimes called Ahmose, stands out in the history of science as the first person we actually know by name who left us math in writing. He worked as a royal scribe in ancient Egypt, probably around 1650 BCE, back when the Hyksos were running things during Egypt’s Second Intermediate Period.
Most people remember Ahmes for the Rhind Mathematical Papyrus, a priceless piece of history that Scottish Egyptologist Alexander Henry Rhind picked up in Luxor in 1858. Here’s the thing, though—Ahmes wasn’t inventing all this math from scratch. Right at the start, he tells us he’s copying an even older text, something originally written several centuries before, during Egypt’s Middle Kingdom, somewhere between 2000 and 1850 BCE.
He opens his work with big ambitions, promising a guide to “accurate reckoning” and knowledge of all things mysterious and hidden. But what you actually get is a down-to-earth handbook: eighty-seven problems tailor-made for the daily life of his time. They’re about trade, measuring buildings, and figuring out how to divide food. From these problems, you get a window into how Egyptians did math, mainly by doubling, halving, and using those clever unit fractions—fractions where the top number is always one.
There’s some neat geometry, too. For example, Ahmes gives a practical way to figure out a circle’s area. The math works out to an implied value of pi as 256 divided by 81, or about 3.16. Not perfect, but surprisingly close for 4,000 years ago. The papyrus also has some early algebra, with what we’d now call linear equations—back then, they called them “aha” problems—and a clever technique called the “method of false position.”
By carefully copying and explaining all this, Ahmes did more than just preserve the math. He became the bridge connecting generations, keeping the world’s oldest practical math alive instead of letting it fade away.
