I was in 12th standard, 2012 was the year. After my Higher Secondary School Certificate exam, I was preparing for the University Admission Test in Udvash Admission Care (a local admission coaching center in Bangladesh).
I vividly remember the day when I
first met Shohag Bhai, the founder of Udvash. Shohag Bhai was teaching us
Higher Secondary Physics that day. He is indeed a man of character, one of the
very few persons whom I respectfully admire from the core of my heart.
I recall a certain incident on that day
when at one point he asked the class,
”Can anybody answer
me why we learn mathematics?
You are learning calculus, geometry,
trigonometry, mechanics – all the tedious tasks sapping your juice outta brain
cells. So where in your life will you apply calculus?
Will you need trigonometry to be a BCS
cadre? Or to write down your shopping list?
Apart from basic addition subtraction
and multiplication, nothing will really be necessary directly in your life.
So why?”
The question had struck us so hard,
all were dumbfounded, including me. I had never put a real thought before on
the true purpose of doing math.
Everybody was silent.
Then Shohag Bhai quipped, ”Doing
mathematics is not the purpose of learning mathematics. The critical thought
you put while solving the math, all the mental pressure and endurance,
tenacity, hard work, those virtues wire your brain positively that the next
time your brain gets more prepared to solve a real-life problem.”
Maybe you are negotiating with your
customer, your mathematical brain circuitry can help you to close a better
deal. Or…
To watch out!
My younger sister gave me this math
problem today. Such an innocent-looking mathematical equation, bring 1 to the
left, square both sides, and solve the quadratic equation, and VOILA! You get
the solution.
Doesn’t take too much effort right?
But
wait for a second, since there is a square root inside the equation, you must
test the equation roots on both the left-hand side and the right-hand side to
see whether the equation is satisfied by the roots or not. Because
presumably, the square value of a variable can give you both positive and
negative answers, which may not satisfy the main equation.
This Math is telling you to watch out!
Finally, you see, the result -1 is not
satisfying the equation’s both sides.
If you hadn’t justified your answers,
you probably would have considered -1 as an answer as well.
I consider myself good at mathematics
since my childhood. I simply love the beauty of this subject. Probably, I have
learned to watch out properly in my life by doing maths.
There are other aspects as well, will discuss another day (I doubt
though, another day never comes).
Time to see how that watching-out
brain circuitry pays me off!
