1. 1. There is No World without Numbers Maths ppt
2. 2. Index Maths in Biotechnology Maths in Astronomy Maths in Mechanics Maths in Chemistry Maths in Medicine Maths in Electronic Maths in Physics Maths in Everyday Life
3. 3. Maths in Biotechnology • Mathematical areas like calculus, probability theory, linear algebra, abstract algebra, graph theory, algebraic geometry, topology, dynamical systems, equations and coding theory are applied in bio- technology.
4. 4. Maths in Astronomy Astronomers use maths all the time It is used to perform calculations when we look at the objects in the sky with a telescope Astronomers use maths when they are forming theories for the physical laws that govern the objects in the sky Some interesting facts The remaining lifetime of the Sun is 4.76 10^9 years Our galaxy milky way is about 100 103 light years wide Moon is about150 million km from the sun The diameter of our planet Earth is 12742 km Temperature of the core of the Earth is 6000 Celsius
5. 5. Maths in Mechanics Mechanical Engineers use Maths with analytical and problem solving abilities to develop or repair new machines Basic maths, calculus and trigonometry are important maths skills required for a Mechanical Engineer The general study of the relationship between motion, forces and energy is called Mechanics 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 meters/second
6. 6. Maths in Chemistry • Mathematics is used widely in chemistry as well as all other sciences • Mathematical calculations are absolutely necessary to explore important concepts in chemistry. • Without some basic mathematics skills, these calculations, and therefore chemistry itself, will be extremely difficult • Scientists put only the digits they can reasonably be certain of in their numbers. They might say, for example, that they measured "10" cm (note the presence of the decimal point).
7. 7. Maths in Medicine • The Human body is the entire structure of a human being and comprises head, neck, trunk, arms, hands, legs and feet • Every part of the body is composed of various types of cell • At maturity the estimate number of cells in the body is given as 37.2 trillion. • In our body there are 206 bones, the temperature of the normal human body is 98.0 • The blood pressure of our body is 120 or over 80, our brain uses 20% of the total oxygen and blood in our body etc
8. 8. Maths in electronics Analytic geometry uses numerical techniques to describe classic geometric concepts including lines, points and curves Analytic geometry uses numerical techniques to describe classic geometric concepts including lines, points and curves Kilowatt Hours - Unit of energy equal to 3.6 mega joules or 1000 watt hours OHM - The SI unit of electrical resistance between two points of a conductor with a difference of 1volt Voltage (Volt) - The SI unit of volts across a conductor when a one ampere current dissipates onewatt of power Watt-Derived unit of power that measures the rate of energy conversion defined in one joule per second Kilowatt-Measure of 1000 watts of standard electrical power or an energy consumption rate of 1000 joules Megavolt - Measure of 1 million Watts of standard electrical power or one joule per second
9. 9. Maths in Physics Physics is probably the one area of science where many aspects of maths has been directly applied Some of the important in Physics are (1)Classical Mechanics (Calculus) (2)Electro Magnetism (Vector Calculus) (3)General Relativity (Differential Geometry) (4)Quantum Field Theory (Matrices, Group Theory) (5)Superstring Theory (Know Theory)
10. 10. Maths in Everyday Life We apply mathematics in simple activities that we do every day Our mother uses the concept of ratios and proportion during cooking Ratio is used to compare quantities Proportion is used along with ratio when the quantity of ingredients increases
