The first integral sign #mathhistory

Imagine if secrets from one of history's greatest minds were still waiting to be discovered. Got freed liabnets invented calculus at the same time as Isaac Newton. Yet after his death in 1716, many of his extensive writings were neglected and remained unpublished while the world celebrated Newton. 200 years later, scholars began to delve into liabnets' untouched manuscripts. Among them was this node from 1675, featuring the first use of the integral sign we know today. In the margins, liabnets wrote the word "summer", Latin for "sum", because integration is about finding the sum of infinitesimal parts. Another major but less-noan mathematical contribution by liabnets is his invention of binary arithmetic. It's been over 300 years since his death, but still nobody has gone through all 200,000 of liabnets' papers. Could his remaining notes hold even more insights?
