چکیده
This paper aims to enrich the teaching of surds. We use explorations with spiral and other geometric patterns, supported by dynamic geometry, to link surds with length through Pythagoras’ theorem, emphasise their relative size and to provide attractive contexts for simple and complex surd calculations. The exact value mode of CAS may support students’ work with surds, allowing them to construct patterns and share a world of beautiful mathematics.

Loxodromic Spirals in M. C. Escher's Sphere Surface
Loxodromic spirals are the analogues in spherical geometry of logarithmic spirals on the plane. M.C. Escher’s 1958 woodcut Sphere Surface is an image of black and white fish arranged along eight spiral paths on the surface of a sphere. By connecting the plane and spherical models of the complex numbers, we show that Sphere Surface is the conformal image on the sphere of a tessellation of fish o...
متن کاملNumerical optimization of hydrofoil geometry for a Darrieus hydraulic turbine using dynamic mesh and central composite design
In this study, a Darrieus hydraulic turbine for power generation applications is chosen and the response surface methodology (RSM) based on central composite design (CCD) is applied to obtain the optimized design for its hydrofoil geometry to increase the torque coefficient. For this aim, all turbine performance factors, except hydrofoil geometry, were considered to be constant and the turbine ...

1. Algebraic Numbers. Early Greeks quadratic irrationals, their existence, their nature: √ 2, √ 3, √ 5, . . . appear in Theatetus (one of Plato’s Socretic dialogues) before Plato simple surds, after Plato more elaborate theory. Found in the later books of Euclid’s elements, the 10 and 12. Combinations of simple surds, such as a √ 2 + b √ 3, a and b rational. Proof of linear independence, thus f...
