10 most difficult mathematics riddlesMathematics quiz
Which mathematician is the inventor of descriptive geometry?
Pierre Simon de Laplace
Gaspard Monge was a French mathematician, the inventor of descriptive geometry, and the father of differential geometry. During the French Revolution he served as the Minister of the Marine, and was involved in the reform of the French educational system, helping to found the École Polytechnique.
Cavalieri's principle is used...
to compare the volumes of solids
to find pime numbers less than 2971
to find all prime numbers from interwal
to check if given number is prime or not
In geometry, Cavalieri's principle, a modern implementation of the method of indivisibles, named after Bonaventura Cavalieri, is in 3-dimensional case: Suppose two regions in three-space (solids) are included between two parallel planes. If every plane parallel to these two planes intersects both regions in cross-sections of equal area, then the two regions have equal volumes.
Which of the following Roman numerals stands for 4?
Both IV and IIII
None of the above
Both notations are correct and historically Roman numerals were often written less consistently than today. The notation 'IIII' is often seen on clock faces. The reason for that may be practical, to avoid confusing the IV and VI when the clock is held upside down (although other theories also exist).
What is the most important work of Claudius Ptolemy from the 2nd-century?
De revolutionibus orbium coelestium
The Almagest is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy (c. AD 100 – c. 170). One of the most influential scientific texts of all time, its geocentric model was accepted for more than 1200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus.
Which mathematician is it?
Gottfried Wilhelm Leibniz
Jules Henri Poincaré was a French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath, and in mathematics as " The Last Universalist"n since he excelled in all fields of the discipline as it existed during his lifetime. He was responsible for formulating the Poincaré conjecture, which was one of the most famous unsolved problems in mathematics until it was solved in 2002–2003 by Grigori Perelman. In his research on the three-body problem.
Which mathematician laid the foundations for abstract algebra (especially the group theory)?
Évariste Galois was a French mathematician born in Bourg-la-Reine. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem standing for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra, and the subfield of Galois connections. He died at age 20 from wounds suffered in a duel.
Which numeral system was in use in ancient Sumer and Babylon?
Remnants of the highly composite sexagesimal system are in use even today for time measurement and geometry. An hour of time is divided into 60 minutes, which in turn are divided into 60 seconds.
The asymptotic triangle has ...?
one semicircular side
all sides equal
all sides concave
two parallel sides
In analytic geometry, an asymptote of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity. In projective geometry and related contexts, an asymptote of a curve is a line which is tangent to the curve at a point at infinity.The word asymptote is derived from the Greek which means "not falling together".
The illustration shows the figure known in mathematics as;
lune of Hippocrates,
In geometry, the lune of Hippocrates, named after Hippocrates of Chios, is a lune bounded by arcs of two circles, the smaller of which has as its diameter a chord spanning a right angle on the larger circle. Equivalently, it is a non-convex plane region bounded by one 180-degree circular arc and one 90-degree circular arc. It is the first curved figure to have its exact area calculated mathematically.
