Karel Zahradnik
Karel Zahradnik (1848–1916) was a mathematician at the University of Zagreb. In his 23 years of productive activity in Zagreb he wrote several significant scholarly works, mainly concerned with algebraic curves In mathematics, an affine algebraic plane curve is the zero set of a polynomial in two variables. A projective algebraic plane curve is the zero set in a projective plane of a homogeneous polynomial in three variables. An affine algebraic plane cu ....

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...

University Of Zagreb
The University of Zagreb (, ) is a public university, public research university in Zagreb, Croatia. It is the largest Croatian university and one of the oldest continuously operating universities in Europe. The University of Zagreb and the University North are the only public universities operating in Northern Croatia, Northern and Central Croatia. The history of the University began on September 23, 1669, when the Holy Roman Emperor Leopold I, Holy Roman Emperor, Leopold I issued a decree granting the establishment of the ''Jesuit Academy of the Royal Free City of Zagreb''. The decree was accepted at the Council of the Croatian Kingdom on November 3, 1671. The Academy was run by the Jesuits for more than a century until the order was dissolved by Pope Clement XIV in 1773. In 1776, Empress Maria Theresa issued a decree founding the ''Royal Academy of Science'' which succeeded the previous Jesuit Academy. Bishop Josip Juraj Strossmayer proposed the founding of a University to the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Zagreb
Zagreb ( ) is the capital (political), capital and List of cities and towns in Croatia#List of cities and towns, largest city of Croatia. It is in the Northern Croatia, north of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb stands near the international border between Croatia and Slovenia at an elevation of approximately above mean sea level, above sea level. At the 2021 census, the city itself had a population of 767,131, while the population of Zagreb metropolitan area is 1,086,528. The oldest settlement in the vicinity of the city was the Roman Andautonia, in today's Šćitarjevo. The historical record of the name "Zagreb" dates from 1134, in reference to the foundation of the settlement at Kaptol, Zagreb, Kaptol in 1094. Zagreb became a free royal city in 1242.

Algebraic Curves
In mathematics, an affine algebraic plane curve is the zero set of a polynomial in two variables. A projective algebraic plane curve is the zero set in a projective plane of a homogeneous polynomial in three variables. An affine algebraic plane curve can be completed in a projective algebraic plane curve by homogenization of a polynomial, homogenizing its defining polynomial. Conversely, a projective algebraic plane curve of homogeneous equation can be restricted to the affine algebraic plane curve of equation . These two operations are each inverse function, inverse to the other; therefore, the phrase algebraic plane curve is often used without specifying explicitly whether it is the affine or the projective case that is considered. If the defining polynomial of a plane algebraic curve is irreducible polynomial, irreducible, then one has an ''irreducible plane algebraic curve''. Otherwise, the algebraic curve is the union of one or several irreducible curves, called its ''Irreduc ...

1848 Births
1848 is historically famous for the wave of revolutions, a series of widespread struggles for more liberal governments, which broke out from Brazil to Hungary; although most failed in their immediate aims, they significantly altered the political and philosophical landscape and had major ramifications throughout the rest of the century.
