An Article by our developer Nalini. An amazing mom, fantastic educator and great friend.
In this blog article, I recount a few
experiences with my son.
When my son was around 7 to 8 months, he
used to crawl his way around.
One day, I had taken him with me to my
friend’s place and we were sitting on the floor chatting. Suddenly I noticed my
son crawling to a toy vehicle which had 3 wheels and the 4th wheel
was missing. He looked around and then took a Vicks bottle lid which is also
circle in shape with diameter similar to that of the wheel and tried to fit it
in place of the missing wheel.
As he grew, I watched him get fidgety to
sit in one place and glowing when he meddles with things around. He used to
watch with absolute calmness when a mason or a carpenter or a plumber works.
As a family, we provided him as much space
as possible. Of course we had to stretch ourselves to the core for it.
Just a few days back, he is all of 12 years
old now and he was telling me about some motors (not the big ones, but those we
got him for his projects) that he was working with and he was telling me the
similarities and difference of two and then the topic moved to a particular
motor which was encased in a plastic case. He told me that it gave high power
o/p and also low rpm (rotations per minute). And then he explained to me how
the low rpm was achieved with the help of gears.
Well, it got me thinking “why should we
spend all the energy to bolster the motor and then spend effort to lower the
rpm?”
I put this question this question to the
rest of the family which includes engineers. They enriched my knowledge on how
if rpm is not reduced, centrifugal force will play havoc and also the wear and
tear.
I also understood that high rpm was needed
to generate the magnetic field and hence power.
And also how modern technology is working on
achieving better efficiency.
Later, when I discussed with my son, he was
telling me if the rpm of the motor in the grinder is not reduced, the dosa
batter would be thrown out and was demonstrating by waving his hands.
On further discussion, he used the word
“centrifugal force”.
Viola ! That’s from my side as a
knowledgeable parent. Do post your experiences and comments.
