On this day:
1830 – U.S. President Andrew Jackson signs the Indian Removal Act which relocates Native Americans.
The Indian Removal Act was passed by Congress on May 28, 1830, during the presidency of Andrew Jackson, who signed it into law two days later. The law authorized the president to negotiate with southern Native tribes for their removal to federal territory west of the Mississippi River in exchange for their ancestral homelands.
The act enjoyed strong support from the non-Native peoples of the South, who were eager to gain access to lands inhabited by the southeastern tribes. Christian missionaries protested against the law’s passage.[why?]
This term was used to discuss the forced relocation of Native Americans from U.S.-claimed states to lands west of the Mississippi River. There was a large amount of resistance from those indigenous people. Cherokee tribes came together as an independent nation to try to stop this relocation; however, they were unsuccessful.
Born on this day:
1676 – Jacopo Riccati, Italian mathematician and academic (d. 1754)
Jacopo Francesco Riccati (28 May 1676 – 15 April 1754) was an Venetian mathematician and jurist from Venice. He is best known for having studied the equation which bears his name.
Riccati was educated first at the Jesuit school for the nobility in Brescia, and in 1693 he entered the University of Padua to study law. He received a doctorate in law (LL.D.) in 1696. Encouraged by Stefano degli Angeli to pursue mathematics, he studied mathematical analysis.
Riccati received various academic offers, but declined them in order to devote his full attention to the study of mathematical analysis on his own. Peter the Great invited him to Russia as president of the St. Petersburg Academy of Sciences. He was also invited to Vienna as an imperial councilor and was offered a professorship at the University of Padua. He declined all these offers.
He was often consulted by the Senate of Venice on the construction of canals and dikes along rivers.
Some of his work on multinomials was included by Maria Gaetana Agnesi, at Riccati’s request, in the book on integral calculus of her Analytical Institutions.
The Riccati equation is named after him.
His father, Conte Montino Riccati, came from a noble family who owned land near Venice. His mother was from the powerful Colonna family. His father died in 1686, when Riccati was only ten, leaving the youth a handsome estate.
Jacopo’s son, Vincenzo Riccati, a Jesuit, followed his father’s footsteps and pioneered the development of hyperbolic functions.
A second son, Giordano Riccati was the first to measure the ratio of Young’s moduli of metals—predating the better known Thomas Young by 25 years.
Jacopo Riccati was named honorary Academician of the Academy of Sciences of the Institute of Bologna in 1723.
