The Relevance Of Quadratic Equations To The Real World
In the previous articles of this series we discussed the relevance of mental arithmetic games to the real world. This time, the emphasis is on the more specific field of quadratic equations and their relevance. This article will highlight some of the various solutions the quadratic equation offers in a historical setting, hopefully proving its worth.
In 2003, at a UK meeting of the National Union of Teachers, the quadratic equation was held aloft to the nation as an example of the cruel torture inflicted by mathematicians on poor unsuspecting school children. Intrigued by this accusation, the quadratic equation was discussed on prime time Radio 4. The Times newspaper took space in its leader column, more usually reserved for weighty discussions on world current affairs, to proclaim that "the quadratic equation was useless, maths was useless and that no one wanted to study maths anyway. So why bother." Concerned that attacks on the quadratic equation remain unchallenged, the vital importance of the equation was even debated in the House of Commons. Fortunately, members of parliament took a more positive view of this much maligned equation.
Quadratic equations are a group of mathematical formula for dealing with finding the value of a variable when three related constants are defined. This method of calculation, though relevant and much used today, has a long history, going back to ancient Egypt and the Berlin papyrus of the Middle Kingdom. Later Greek and Indian mathematicians refined and made use of the formula.
The Babylonians recorded their calculations, on clay tablets, highlighting their use of the quadratic equation to deal with agricultural problems. By knowing the amount of crop a particular field would yield, and knowing the basic measurements of a neighbouring field, they could predict the crop yield, which was useful for tax purposes.
The Greeks also made use of quadratic equations about a millennium after the Babylonians. The Greeks were very careful about the proportions of public buildings they erected, particularly temples, because they wanted to reflect the perfect harmony of nature and the gods around them. The Greeks believed in a rectangle which had the most aesthetic proportions,[url=http://www.sport.fr/business/louisvuitton.html]louis vuitton pas cher[/url], the so called Golden Rectangle. This form is repeated in the various elements of a building and calculating its dimensions according to the scale of the building would be done by using a quadratic equation.
In today's world, quadratic equations are often employed for business solutions. So, for example: if 2 bricklayers can lay 5 m. of wall a day, how many bricklayers would be required over 4 days to lay 50m? This can be calculated with the use of this equation.
So the quadratic equation is here to stay, tried and tested over centuries to provide us with solutions applicable to our everyday lives.
