Maths in Our Daily Life — Presentation Transcript * 1. MATHEMATICSIn Our Daily Life * 2. INTRODUCTIONFor more than two thousand years, mathematics has been a part of the human search for understanding. Mathematical discoveries have come both from the attempt to describe the natural world and from the desire to arrive at a form of inescapable truth from careful reasoning. These remain fruitful and important motivations for mathematical thinking, but in the last century mathematics has been successfully applied to many other aspects of the human world: voting trends in politics, the dating of ancient artifacts, the analysis of automobile traffic patterns, and long-term strategies for the sustainable harvest of deciduous forests, to mention a few. Today, mathematics as a mode of thought and expression is more valuable than ever before. Learning to think in mathematical terms is an essential part of becoming a liberally educated person. * 3. Mathematics first arose from the practical need to measure time and to count. The earliest evidence of primitive forms of counting occurs in notched bones and scored pieces of wood and stone. Early uses of geometry are revealed in patterns found on ancient cave walls and pottery. As civilisations arose in Asia and the Near East, sophisticated number systems and basic knowledge of arithmetic, geometry, and algebra began to develop.The History of Mathematics * 4. Early CivilasationsThe ancient Egyptians (3rd millennium BC), Sumerians (2000- 1500 BC), and Chinese (1500 BC) had systems for writing down numbers and could perform calculations using various types of abacus. The Egyptians were able to solve many different kinds of practical mathematical problems, ranging from surveying fields after the annual floods to making the intricate calculations necessary to build the pyramids. Egyptian arithmetic, based on counting
