Non-Riemannian geometry and the theory of lattice imperfections
(2003)Creation and development of continuum theory of imperfections of a crystal structure (dislocations and disclinations) is closely associated with ideas and methods of non-Euclidean and non-Riemannian geometry. In the ... -
Street gambling, mathematization and the mathematical expectation
(2003)Concepts, theorems and the methodology of probability calculus were born - no doubt for that - in gambling saloons. In the gambling land we find traces of history and culture, but also of sciences. The present paper ... -
The space imagination on the cube
(2003)The contribution presents some results of the space imagination research on the cube carried out on 9-to-12-year old students. The experiment is based on a task situation called “Tilting a die”, in which a student “tilts” ... -
Probability and statistics : a modular system of instruction at the University of J. E. Purkyně in Ústí nad Labem
(2003)Probability and Statistics courses are offered at three colleges of the University of J.E. Purkyne in Usti nad Labem and at the Institute of Engineering Technology. These courses make part of the required curricula for ... -
E-leaming in arithmetic courses delivered in the combined form of study for primary school teachers
(2003)E-learning of teaching arithmetic designed for future primary schools teachers — a combined form of study Implementation of e- learning in the distant course for future primary schools teachers based on the arithmetic ... -
On the understanding of geometric transformations by mathematics freshmen
(2003)Two questions will be discussed in my paper. The first one concerns difficulties the first year university students meet while learning definition of the geometrical transformation. The second question - the incorrect ... -
Prospective teachers and mathematical word problems
(2003)Mathematical word problems and the solving process of them within the framework of the system of educational aims and pedagogical competencies of primary and secondary school teachers. Experience with developing the ... -
Mathematical logic and mother tongue
(2003)Logical thinking is closely connected to the terms statement and logical evaluation (determination if it is true or false). A sentence is the language expression of thought. It means that logical thinking is closely ... -
No arbitrage condition for financial market with inflation
(2003)When price dynamics in the financial market is modeled as a continuous-time mathematical model, it is assumed that the interest rates in the market follow stochastic differential equations. The noarbitrage condition in ... -
Solutions to a certain problem illustrating the idea of fusionism in the probability theory
(2003)The solutions presented above may serve as an illustration of "the principle of internal integration”, known as the idea of liisionisiii. Three balls are selected simultaneously from an urn containing b white balls and ... -
Wallas - Polya - Hadamard and creativity
(2003)Comparison of theories of G. Wallas and G. Polya with school practice Wallas: 1. Preparation (hard work on a problem). 2. Incubation (concious preparation is changed into unconscious mechanism of searching for the ... -
Awaiting the series of colors - stochastic graph as a means of mathematical treatment and argumentation
(2003)This paper presents methods of calculating the probability of events related to Markov’s homogeneous chains theory. The main means of argumentation being the stochastic graph. -
Computers and teaching mathematics
(2003)It looks as if the school shut eyes to progress. The computers help everywhere, but schools are short of them. The computers would be the most effective teaching aid. The school does not react to pupils’ knowledge reached ... -
Fibonacci sequence II (helping students become active learners through guided mathematical investigations)
(2003)Elementary number theory provides a variety of topics suitable for guided investigation in mathematics (the scheme of investigation is diagramed). We demonstrate this with the help of non-traditional and fascinating topic ... -
Direction field of fingerprint image and its optimization with the help of relaxation procedures
(2003)Direction field building has an exclusive importance for common process of the classification analysis in up-to- date automatic fingerprint identification systems. All characteristics of this analysis strongly depend on ... -
Pythagorean TRIPLES
(2003)Students should learn mathematics with understanding, actively building new knowledge from experience and prior knowledge. We describe how one can describe all integer solutions of the equation $a^2+b^2 = c^2$ by utilizing ... -
About practical exercises taken from real life
(2003)Review of bibliography. Contemporary requirements in mathematical teaching. Classification of exercises occurring in mathematics school books. Analysis of selected primary and secondary school books considering the use ... -
On children's understanding of area
(2003)Area and volume belong to the most important geometrical concepts due to their broad application outside mathematics. Certain problems connected with the understanding of “area” observed in 11 year old children will be ... -
Two problems solved with MS-Excel
(2003)The first problem arising in the theory of graphs is to find the maximum flow in a network. This is equivalent to the problem of finding a minimum cut, according to Ford-Fulkerson algorithm, which is briefly explained. ... -
The finite subsets of natural numbers
(2003)The article discusses relationships between triangle and square numbers. The stress is laid upon numerical equality. A finite set of these numbers and its subsets are given by software. Finding natural numbers with a ...
