USES OF

MATHSsome random thoughts from

Mathematics may be described as the fundamental science. It may be broadly described as the science of space, time and number. The universe exists in space and time, and is constituted of units of matter. To calculate the extension or composition of matter in space and time and to compute the units that make up the total mass of the material universe is the object of Mathematics. For the space-time quantum is everywhere full of matter and we have to know matter mathematically in the first instance.

MATHS IN

EVERYDAY

LIFE

Some people aren't even out of bed before encountering math. Setting an alarm and hitting snooze, they may quickly need to calculate the new time they will arise. Or they might step on a bathroom scale and decide that they’ll skip those extra calories at lunch. People on medication need to understand different dosages, whether in grams or milliliters. Recipes call for ounces and cups and teaspoons --all measurements, all math. And decorators need to know that the dimensions of their furnishings and rugs will match the area of their rooms

AT HOME

IN TRAVEL Travelers often consider their miles-per-gallon when

fueling up for daily trips, but they might need to calculate anew when faced with obstructionist detours and consider the cost in miles, time and money. Air travelers need to know departure times and arrival schedules. They also need to know the weight of their luggage unless they want to risk some hefty baggage surcharges. Once on board, they might enjoy some common aviation-related math such as speed, altitude and flying time.

AT SCHOOL AND WORK

Students can’t avoid math -- most take it every day. However, even in history and English classes they may need to know a little math. Whether looking at time expanses of decades, centuries or eras or calculating how they’ll bring that B in English to an A, they’ll need some basic math skills. Jobs in business and finance may require sophisticated knowledge of how to read profit and earning statements or how to decipher graph analyses. However, even hourly earners will need to know if their working hours times their rate of pay accurately reflects their paychecks.

PASTIMES Even off-time can be math time. Baseball fans know a

lot about statistics, whether they’re considering basic win-loss ratios, batting averages or pitchers' earned-run-averages. Football fans know about yardage gains and passing stats. And individual athletes, whether runners, bikers, sailors or hikers, often have their own ways of charting their progress, from time to mileage to elevation.

Geometry in real life

What is Geometry?

Geometry is one of the classical disciplines of math.

Roughly translating in Greek as "Earth Measurement", it is concerned with the properties of space and figures.

It is primarily developed to be a practical guide for measuring

lengths, areas, and volumes, and is still in use up to now.

Enough of the

basics, now let’s get back to the

topic.

When do we actually

use Geometry?

Area problems are one of the most common uses of

geometry in our everyday lives. Let's say you need to install new carpet in your bedroom. How much carpet will you need to buy? Measure your room's length and width and then multiply them together to find out how many square feet of carpeting is needed. This is represented by the formula A = L x W, or area equals length times width. If, for example, your room is 12 feet by 10 feet, you will need 120 square feet of carpet.

Another area problem you may encounter is determining

how many cans of paint to buy to cover your walls. The label on the gallon of paint tells you it will cover 400 square feet. You

measure your walls and find that the room you want to paint has walls of the following dimensions: 10 ft x 10 ft, 10 ft x 8 ft, 10 ft x 10 ft and 10 ft x 8 ft. So you need to cover the areas of 100 square feet + 80 square feet + 100 square feet + 80 square feet = 360 square feet. Your room can be single coated by one can of paint.

Perhaps you are planning a garden. A bag of fertilizer says it can cover 100 square feet. You need

to know how many bags you will need. Measure the area of your garden (length times width) to find your area. Let's say my garden measures 40 feet by 20 feet. That means I need to cover 800 square feet of area with fertilizer. Divide 800 by 100 and you get 8. We need 8 bags of fertilizer for my garden.

A mechanical engineer designs machines ranging from tiny gearsets to large construction cranes. Using geometry, he determines the strongest shapes for mechanical parts. He calculates the area, weight and volume of pieces and ensures that a machine's thousands of moving parts fit together and don't interfere with one other.

A surveyor uses trigonometry, a branch of geometry, to

measure distances and angles between points on land. Trigonometry uses the mathematical properties of right triangles; by measuring one angle and one distance, the surveyor can calculate the lengths of the other sides and the angles between them. While computerized and automated equipment now does the actual work of calculation, the surveyor must understand the principles behind the calculations to perform the measurements correctly.

A mathematician uses sophisticated conceptual tools to investigate the properties of shapes. Using proofs, which justify geometric ideas in a clear, step-by-step manner, he lays the mathematical foundations for new ideas in geometry. The mathematician then publishes these ideas, and people of other occupations adopt them in useful ways. The mathematician also educates and trains students in using geometry, proofs and mathematical concepts.

Mathematician

A graphic designer studies how basic geometric shapes combine into artistic visual layouts in two and three dimensions. A graphic artist

uses geometric concepts such as perspective and golden ratios to create the most pleasing designs. He uses computer graphical tools that break complex, realistic images into many basic circles, lines and polygons.
