• 1. APPLICATION OF MATHEMATICS IN SCIENCE Presented by Name- Dipanwita Sutradhar Class – IX-B Roll-17
• 2. WHAT IS MATHS? O Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, computers, software, architecture (ancient and modern), art, money, engineering and even sports.
• 3. What is the use of mathematics in science? O Mathematics is an intrinsic component of science, part of its fabric, its universal language and indispensable source of intellectual tools. Reciprocally, science inspires and stimulates mathematics, posing new questions, engendering new ways of thinking, and ultimately conditioning the value system of mathematics.
• 4. MATHS IN BIOTECHNOLOGY  Like calculus, linear algebra, graph geometry, equations and coding theory is used.  For finding the estimation of DNA, there is use of maths.  Calculate the composition of any culture.  There is lots of subjects come in biotechnology like bioinformatics, fluid mechanics, heat transfer, physics, chemistry, biostatics etc.
• 5. MATHS IN ASTRONOMY O Astronomers use maths all the time O It is used to perform calculations when you look at the object in the sky with a telescope. O Some of interesting facts • Our galaxy milky way is about 10 x 103 light years wide • Moon is about 150 million km away from us • The diameter of our planet earth is 12742 km
• 6. MATHS IN MECHANICS O Mechanical engineers with analytical problem solving abilities to develop or repair new machines. O The general study of the relationship between motion. Force and energy is called mechanics. O Examples of application of maths in mechanics • Speed is measured as distance travelled / time taken • Force exerted=Mass x Acceleration • Gravity of earth is 9.8 metres / second2
• 7. MATHS IN CHEMISTRY O Chemists use math for a variety of tasks . O They balance the equation of a chemical reaction ,use mathematical calculations that are absolutely necessary to explore important concepts in chemistry. O Maths is also used to calculate energy in reactions, compression of a gas, grams needed to add a solution to reach a desired concentration, and quantities of reactants needed to reach a desired product.
• 8. MATHS IN MEDICINE O Medical professionals use maths when drawing up statistical graphs of epidemics or success rates of treatments. O Maths is used to do X- rays and CAT Scans .
• 9. MATHS IN PHYSICS O Physics is probably the one area of science where many aspects of maths has been directly applied. O Some of the important in physics are • Calculus • Vector Calculus • Differential Geometry • Matrices , Group theory • Know Theory
