The Physics of Weightlifting
After months of practise, hard work (typical ain’t it?) has yielded results. The medal at open IIT Powerlifting reaffirmed some of my beliefs of the alchemical process
- Mentors play a very significant if not pivotal role.
- One has to be inebriated by hope and leave the rest to chance. (I am not much of a believer of a greater Force, but I do believe in the chance mechanism)
- Independent thought is necessary in any endeavour.
Although some of my readers may argue that all you need to do for weightlifting is eat eggs and lift weights, I am afraid that your view of weightlifting is at best naive. For the IITian, it is always doing with understanding.
A Question of Torque
Any layman could tell you that you have to balance the weights if you can hope to lift any significant weight. If the weights aren’t balanced you are going to have a tough time. If we assume the rod to have homogenous density, then the length of the rod should be equal on both sides.
Minimizing the work done
Why is a bench press done with an arched back? To minimize the distance travelled and hence the work done (W = Fs). As elementary as that.
Components of Force
A deadlift is always done with the shoulders and the arms in the vertical plane. What does it ensure? You get the entire force of your arms to be working against the gravity. The moment there is an angle, the horizontal component of force comes in and energy is wasted.
Yin and Yang
The grip for a deadlift is always complementary. If one hand grips the bar with an open palm, the other with a closed palm. As you can see in the diagram below, this way the horizontal component of the force gets cancelled and the bar remains in firm grip.
Ok, so that is how an IITian would lift weights. I hope I have changed the viewpoint of many who believed that weightlifting was all brawn and no brains.

A Curious Case of Jalebis and Roshogollas
![]() |
Looks yummy, doesn't it? Roshogollas and Jalebis. A Sweet Treat.
That is what I thought when we were first taken for the treat on 6th October. A Sweet Treat.
That day I learnt - It is nice to have sour food items too.
Why the treat?
Bimala Sweets at 0700 hours for a sweet treat. I was all confused. Has OP started again? Or is it the OP treat? Placement treat? Illumination treat.
I have never appreciated sweets much. More so, the idea that someone should push sweets down my throat is something I had never concocted in my wildest imagination.
But this was Nehru Hall. And Nehru Hall has 'some tempo'.
Tempo to do what I really don't know - but 'some tempo'. In Kgp lingo, tempo is the enthusiasm/zeal one shows in doing something. Higher the zeal - higher the tempo.
So for 'God knows what reason' we were taken for this treat. Most of us were puzzled. Even more puzzling was the presence of first year students.
"You won't be served again"
In the first round, we are served Jalebis. "Take as much as you can. You won't be served again".
I take two Jalebis.
What ensued can best be described in the C programming language as follows...
do{
if(!eating)
Push 5 jalebis/roshogollas down his throat;
else
Serve more; //"Please take atleast 3"
if(Professor's arrive)
break;
}(1);
My final count
9 Roshogollas. 10 Jalebis.
Not as many as compared to many of my batchmates.
But I am not the kind of person who can swallow whatever is pushed down the throat.
For my throat takes only that much as my stomach can digest.

The Frog and the Nightingale?
Once upon a time a frog
Croaked away in Bingle Bog
Every night from dusk to dawn
He croaked awn and awn and awn
Other creatures loathed his voice,
But, alas, they had no choice,
And the crass cacophony
Blared out from the sumac tree
At whose foot the frog each night
Minstrelled on till morning light
[+/-]Read On
If you still haven't figured it out - I hope you have. But if you haven't - try moving your mouse over the italicized text - line by line. Cheers!!!
P.S: Suggestions welcome!

Is the OP really over?
I woke up from sleep today morning feeling really fresh. I had woken up from a marathon 10 hour sleep after staying awake for 40 hours - which included a night out.
The lethargy & tiredness of sleeplessness has been drowned by the excitement of a single news - OP is over.
Yes, it is over. OP is finally over. And with a bang.
Lights, Camera Action.
It is 4 o' clock in the morning. I have been practising for the Bengali Dramatics since 10 o' clock in the night. Suddenly, we are summoned to D-Ground.
Artificial lighting is on. All second year students are sitting in neat queues with their legs crossed on the wet early morning grass (The sun hasn't risen yet). Seniors are standing at strategically selected vantage points.
Q: How many 5th year wings have you covered?
A: None
Thwack! A slap lands plum on the left cheek very close to the ears. The spectacles fly and land a few feet away on the ground. Everything is now hazy.
More arbit questions can be heard.
More arbit answers.
More slaps.
No one is spared.
In the mayhem, the Hall President announces - you OP ends.
Everybody is confused.
Buckets full of water come splashing from the wing above. Reality dawns. Yes, the OP is truly over.
The regular traditional ceremonies take place. The Oath, the Anthem & then the treat.
The spectacles are now back on the nose. But the question still remains.
Is the OP really over?

Ambigram: Nehru
Nehru is the name of the new Hall of Residence which I have been allotted in IITKgp.



Insults or complaints or bricks
Stilled the frogs determination
To display his heart's elation.
But one night a nightingale
In the moonlight cold and pale
Perched upon the sumac tree
Casting forth her melody
Dumbstruck sat the gaping frog
And the whole admiring bog
Stared towards the sumac, rapt,
And, when she had ended, clapped.
Ducks had swum and herons waded
To her as she serenaded
And a solitary loon
Wept, beneath the summer moon.
Toads and teals and tiddlers, captured
By her voice, cheered on, enraptured:
“Bravo!” “Too divine!” “Encore!”
So the nightingale once more,
Quite unused to such applause,
Sang till dawn without a pause.
Next night when the Nightingale
Shook her head and twitched her tail,
Closed an eye and fluffed a wing
And had cleared her throat to sing
She was startled by a croak.
“Sorry – was that you who spoke?”
She enquired when the frog
Hopped towards her from the bog.
“Yes,” the frog replied. “You see,
I'm the frog who owns this tree
In this bog I've long been known
For my splendid baritone
And, of course, I wield my pen
For Bog Trumpet now and then”
“Did you… did you like my song?”
“Not too bad – but far too long.
The technique was fine of course,
But it lacked a certain force”.
“Oh!” the nightingale confessed.
Greatly flattered and impressed
That a critic of such note
Had discussed her art and throat:
“I don't think the song's divine.
But – oh, well – at least it's mine”.
“That's not much to boast about”.
Said the heartless frog. “Without
Proper training such as I-
And few others can supply.
You'll remain a mere beginner.
But with me you'll be a winner”
“Dearest frog”, the nightingale
Breathed: “This is a fairy tale –
And you are Mozart in disguise
Come to earth before my eyes”.
“Well I charge a modest fee.”
“Oh!” “But it won't hurt, you'll see”
Now the nightingale inspired,
Flushed with confidence, and fired
With both art and adoration,
Sang – and was a huge sensation.
Animals for miles around
Flocked towards the magic sound,
And the frog with great precision
Counted heads and charged admission.
Though next morning it was raining,
He began her vocal training.
“But I can't sing in this weather”
“Come my dear – we'll sing together.
Just put on your scarf and sash,
Koo-oh-ah! ko-ash! ko-ash!”
So the frog and nightingale
Journeyed up and down the scale
For six hours, till she was shivering
and her voice was hoarse and quivering.
Though subdued and sleep deprived,
In the night her throat revived,
And the sumac tree was bowed,
With a breathless, titled crowd:
Owl of Sandwich, Duck of Kent,
Mallard and Milady Trent,
Martin Cardinal Mephisto,
And the Coot of Monte Cristo,
Ladies with tiaras glittering
In the interval sat twittering –
And the frog observed them glitter
With a joy both sweet and bitter.
Every day the frog who'd sold her
Songs for silver tried to scold her:
“You must practice even longer
Till your voice, like mine grows stronger.
In the second song last night
You got nervous in mid-flight.
And, my dear, lay on more trills:
Audiences enjoy such frills.
You must make your public happier:
Give them something sharper snappier.
We must aim for better billings.
You still owe me sixty shillings.”
Day by day the nightingale
Grew more sorrowful and pale.
Night on night her tired song
Zipped and trilled and bounced along,
Till the birds and beasts grew tired
At a voice so uninspired
And the ticket office gross
Crashed, and she grew more morose -
For her ears were now addicted
To applause quite unrestricted,
And to sing into the night
All alone gave no delight.
Now the frog puffed up with rage.
“Brainless bird – you're on the stage –
Use your wits and follow fashion.
Puff your lungs out with your passion.”
Trembling, terrified to fail,
Blind with tears, the nightingale
Heard him out in silence, tried,
Puffed up, burst a vein, and died.
Said the frog: “I tried to teach her,
But she was a stupid creature –
Far too nervous, far too tense.
Far too prone to influence.
Well, poor bird – she should have known
That your song must be your own.
That's why I sing with panache:
“Koo-oh-ah! ko-ash! ko-ash!”
And the foghorn of the frog
Blared unrivalled through the bog.
