Mathematics and Life 103 You know maths - Parallel lines

 You know maths - Parallel lines 


Background  In continuity of the framework You know maths, today I would like to discuss the concept, examples and non examples of parallel lines, spaces, surfaces, planes in daily life, sciences and so on.


Parallel means which do not meet at any point. In school mathematics, we use this term for two or more lines which never meet. It means, however you extend them on both sides, there is no point at which they will cross or meet each other. There are many properties of parallel lines with reference to various angles between them and the transversal (a line crossing or cutting them at different points). About them we will discuss in a separate post.


Examples of parallel lines lines drawn in a notebook, lines drawn on a graph sheet, printed lines in a book, opposite sides of a parallelogram / rhombus / rectangle / square, 


Parallel lines / surfaces in life opposite sides of a notebook, door frames, bars in a window, legs of a study table, floor of the car to the ground, opposite sides of a ladder, stair case steps, in big movies / novels some characters are parallel they never meet each other, eye movement, gymnastics bars, railway tracks, opposite wheels of a car are aligned to be moving parallel, fencing wires are parallel, floor and roof in a house are parallel, so are the opposite walls. In fact, a multi storied building cannot be raised if the floor is not parallel to the roof. In PERT / CPM, many ideas / subprojects run parallel. 


Equal intercept means same gap between parallel lines. Like big stairs on old Jain temples or the famous Girinar temple with 10,000 stairs are having all stairs at equal intervals. This reduces the fatigue. Shirt / coat buttons are at equal distance,  although not exactly parallel, but trees in the forest also never cross each other.


Maths of life On a philosophical note, we can say that God or Nature has made all its creations parallel and self sustainable. Birds, animals, sea life, trees, shrubs, micro organisms, air, fire, earth, sky, rivers, sea,  all have parallel existence. Come man on the scene, all get intercepted.

Mathematics and Life 1 Introduction to the article series by Beyond Abacus

Purpose of the series is to explain various basic mathematics concepts in simple language connecting concepts to examples from life,business, science, day to day life. It will be our special emphasise to develop what Dr. Prakash Moghe calls the math - language interface. That is, showing similarity between the words used in daily language and mathematics like point, ray, interest and so on......     Audience This series of posts is for everyone who wants to understand, learn, revise, apply maths concepts, formulae, and wants to develop Problem Solving Approach, critical thinking, design thinking, and mathematical thinking. Agewise , from age 6 to the time one wants to learn / revise / teach basic maths will find these posts useful in their own ways. Frequency of posts At least one post a day has been planned. Length of posts Each post will be self content, so will be long enough to elaborate the point and short enough to keep the reader engaged. The reach Each post wil...

Mathematics and Life 2 About me - Early Childhood to formating years

  Overview  Past   36 years I have been a maths classroom teacher by choice.  Childhood and family Born in a Maharashtrian Bramhin family in 1960, with father being a medical doctor, childhood was very blissfully ignorant of the ground realities of the world. Being a government doctor with zero PR activities, I continue the trend, transfer or long posting in tribal areas was a norm. We spent 6 years in Bastar district in early 1970s. One of the most interesting things to recall is we three brothers often used to sit and talk a lot in Hindi. In the presence of parents, we three used to interchangeably toggle Hindi - Marathi. Hindi with brothers, Marathi with parents. In 8th standard, the elder brother school fee was a whopping 30 paise per month, my huge fee was 15 paise per month and the third had to pay nothing in the Government Multi purpose school Bastar. Moving to Indore To reduce the stressful impact of transfers on our studies, in 1976 myself and elder bro...

Mathematics and Life 4 Mathematics as just a computational tool

  The importance of definition  I would like to discuss how the policy makers', parent body, school administrators, investors', teachers' perception of what is it to be good at maths ? affects the students and ultimately the workforce, industry, economy in general. 1. Mathematics as a computational tool    This is the current, popular perception of knowing maths. Our classroom teachings, examination system, wide spread tutoring, coaching business all tend to develop, appreciate, the skill of reaching one unique answer as fast as possible. The Abacus or its various versions, as a training tool are classic examples of this. Students are expected to be too good at a skill in past 61 years of life I have not needed. I ask the readers, how often, if at all, you needed to find 5813 x 3876 infraction of a minute and that too accurately ? I bet never. But, just as a ritual, under peer pressure children go year after year to learn something which is first of all not needed at...
