Dodecahedron

In the previous section, we mainly focus on the connectivity and related survivability issues of WSNs. It is the foundation that we deploy WSNs to achieve its main objective which is to monitor the field of interest / detect desired data and it is coverage that determines whether the field of interest is under strict surveillance or not. So, in this section, we will summarize the related work on integrated connectivity and coverage problem in WSN. In [68], [69], it’s clear that connectivity only

Johannes Kepler: A Man of Math Johannes Kepler was born in a small town in Germany during the late sixteenth century. His discoveries helped change the world and influence people such as Isaac Newton who actually derived his universal law of gravitation from Kepler’s Laws. Kepler learned many things such as what causes the oceans tides and had his own version of Fermat’s Last Theorem called Kepler’s Last Theorem. Kepler even proved logarithms and developed volumes of solids by revolution which contributed

windows in the painting look out to a vast landscape that represents a bay near Dali’s hometown of Port Lligat, Spain ("Salvador Dali The Sacrament of the Last Supper, c.1955”). The room containing Christ and the twelve disciples is shaped like a dodecahedron, which has twelve sides, with each side of the shape mirroring a disciple. The twelve disciples lining both sides of the central Christ have their heads down, not making eye contact with the viewer, essentially appearing to be in mourning at what

Polygon From Wikipedia, the free encyclopedia Jump to: navigation, search For other uses, see Polygon (disambiguation). Some polygons of different kinds In geometry a polygon ( /ˈpɒlɪɡɒn/) is a flat shape consisting of straight lines that are joined to form a closed chain or circuit. A polygon is traditionally a plane figure that is bounded by a closed path, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). These segments are called its edges or sides

I. Greek Mathematicians Thales of Miletus Birthdate: 624 B.C. Died: 547-546 B. C. Nationality: Greek Title: Regarded as “Father of Science” Contributions: * He is credited with the first use of deductive reasoning applied to geometry. * Discovery that a circle is bisected by its diameter, that the base angles of an isosceles triangle are equal and that vertical angles are equal. * Accredited with foundation of the Ionian school of Mathematics that was a centre of learning and research
