When the math historian discovered decimals in a 1440s treatise & freaked out.

What is the decimals age?

You’ve probably never given it much thought, but some historians have found it fascinating. Being fascinated isn’t hyperbole. Glen Van Brummelen is a mathematics historian at Trinity Western University in Canada. He tells Nature News that while teaching at a middle school math camp, he noticed a decimal used to represent tenths of a number in a 15th-century treatise. “I remember running up and down the hallways of the dorm with my computer trying to find anybody who was awake, shouting ‘Look at this, this guy is doing decimal points in the 1440s!'” It turns out that math historians find this early appearance of such a decimal to be quite significant. What Science Alert refers to as “a mind-blowing discovery.”

Although decimals have been in use since the 900s, German mathematician Christopher Clavius is credited with being the first to divide entire numbers into tenths, hundredths, and thousandths in his Astrolabium, a treatise on the astrolabe, published in 1593. The similar usage in a Much older work was what Van Brummelen had found. Using the sexagesimal numbering system, which divides a 360-degree circle into 60 minutes and minutes into 60 seconds, European astronomers performed computations in the 1440s. According to Nature News, the system employs 60 as its foundation, much like our current decimal system uses 10. However, this makes multiplication challenging and necessitates many value conversions.

Astronomer Giovanni Bianchini of Venice discovered a more straightforward method that José Chabás, an unrelated astronomy historian, tells Live Science was “a step forward for humanity.” Van Brummelen and a colleague discovered that Bianchini was dividing angles into minutes and seconds but reporting the values as numbers with decimals using the base-10 system while going over his treastise Tabulae primi mobiliz B. According to Van Brummelen, the author of a paper that was published online for Historia Mathematica, Bianchini is credited with creating the technique because of his expertise in economics, which would have allowed him to understand computations using practical measures. Chabás argues Clavius would have known about his work.
