Blanuša was born in Osijek and attended elementary school in Vienna and Steyer in Austria and gymnasium in Osijek and Zagreb. Osijek (ˈɔsjɛk is the fourth largest city in Croatia with a population of 114616 in 2001 Vienna ( in Wien; see also other names) is the Capital of Austria, and is also one of the nine States of Austria. Steyr is a town in the Austrian federal state of Upper Austria, located at the confluence of the rivers Steyr and Enns. Austria (Österreich ( officially the Republic of Austria (Republik Österreich A gymnasium (pronounced with ɡ- in several languages is a type of school providing Secondary education in some parts of Europe, comparable to English grammar Zagreb (ˈzɑːgrɛb is the Capital and the largest city of Croatia. He studied engineering in both Zagreb and Vienna and also mathematics and physics. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. His career started in Zagreb, where he started to work and lecture. Blanuša was the dean of the Faculty of Electrical Engineering and Computing in the 1957-58 school year. In Academic administration, a dean is a person with significant authority over a specific academic unit or over a specific area of concern or both The Faculty of Electrical Engineering and Computing (Fakultet elektrotehnike i računarstva abbr: FER) is one of the top faculties of He received the Ruđer Bošković prize in 1960.

Mathematics

In mathematics, Blanuša became known for discovering the second and third known snarks in 1946 (the Petersen graph was the first), triggering a new area of graph theory. In Graph theory, a snark is a connected bridgeless Cubic graph with Chromatic index equal to 4 In Graph theory, the Petersen graph is an Undirected graph with 10 vertices and 15 edges In Mathematics and Computer science, graph theory is the study of graphs: mathematical structures used to model pairwise relations between objects These graphs are part of the solution of the 'four color problem', i. e. the proof of the four color theorem. The four color theorem (also known as the four color map theorem) states that given any plane separated into regions such as a political map of the states of a country (Snarks were so named by the American mathematician Martin Gardner in 1976, after the mysterious and elusive object of Lewis Carroll's poem The Hunting of the Snark). Martin Gardner (b October 21, 1914, Tulsa Oklahoma) is a popular American mathematics and science writer specializing in Recreational mathematics Charles Lutwidge Dodgson (ˈdɒdsən (27 January 1832 &ndash 14 January 1898 better known by the Pen name Lewis Carroll (/ˈkærəl/ was an English " The Hunting of the Snark (An Agony in 8 Fits " is a nonsense Poem written by Lewis Carroll (Charles Lutwidge Dodgson in 1874 when he was 42 years

Blanuša's most important works were related to isometric immersions of two-dimensional Lobachevsky plane into six-dimensional Euclidean space and generalizations, in the theory of the special functions (Bessel functions), in differential geometry, and in graph theory. Isometric projection is a form of Graphical projection —more specifically an Axonometric projection. Nikolai Ivanovich Lobachevsky (Никола́й Ива́нович Лобаче́вский ( December 1 1792 &ndash February 24 1856 ( N Euclid ( Greek:.) fl 300 BC also known as Euclid of Alexandria, is often referred to as the Father of Geometry In Mathematics, Bessel functions, first defined by the Mathematician Daniel Bernoulli and generalized by Friedrich Bessel, are Canonical Differential geometry is a mathematical discipline that uses the methods of differential and integral Calculus to study problems in Geometry In Mathematics and Computer science, graph theory is the study of graphs: mathematical structures used to model pairwise relations between objects His results are included in the Japanese mathematical encyclopedia Sugaku jiten in Tokyo, published by Iwanami Shoten in 1962.

His Erdős number is 6. The Erdős number (ɛrdøːʃ honoring the late Hungarian mathematician Paul Erdős, is a way of describing the "collaborative distance" between a person

Physics

His works were mostly related to the theory of relativity. He discovered a mistake in relations for absolute heat Q and temperature T in relativistic phenomenological thermodynamics, published by Max Planck in Annalen der Physik in 1908. In Physics, thermodynamics (from the Greek θερμη therme meaning " Heat " and δυναμις dynamis meaning "

This correction was published in Glasnik, the journal relating to mathematics, physics and astronomy in 1947 in the article "Sur les paradoxes de la notion d'énergie". Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Astronomy (from the Greek words astron (ἄστρον "star" and nomos (νόμος "law" is the scientific study It was rediscovered in 1960, and the correction is still wrongly attributed to H. Ott in the mainstream scientific literature.
