Tuesday's Matha tutorial .I went therejust to see who the new tutor is?Anyawy it was supposed to 1 hour business only.As I was free afterwards.To my surprise it was a lady tutor replacing the old psycho who always used to brag about his busy schdule.Here is how I felt during that tutorial session.
"Another waste of an hour .If not it will be wasted in another 20 mins.This maths really makes a foul smelling curd out of my mind.This is a stinky subject for me .I can't decipher a single line what she says.Though she is solving all the problems but her voice is too feeble to be heard.Damn I can't hear a single word of her.
Can't she be
Yeah she is pretty but equally boring like maths.I got a D last sem.
Can't she be blessed with a louder voice?
Can't she teach any other interesting subject leaving maths for that old psycho?
What is she writing on the blackboard with a cute smile?
Ok leave it .Yesterday also I encountered a beauty in H.C.
God!!!!
I can't forget the glow of her face.Her smile was simply stunning. But she was phisically devoid of 1 hand.I really felt dismal for her,but this is what we call life"
Tin-tin-tin-tin-tin
"Oye kahan kho gaya class khatm ho gayi hai." Amit patel shouted at my ears.

My Learning Curve.Part-I
Here is a Post regarding my learning curve at IIT-K.The activities of GE3 has fascinated me the most.The following article is an evidence to me that I learnt something from them.GE3 is a group of young thinkers who believe possibilities of utilising alternative sources to produce and conserve energy can be turned into oppurtunities and oppurtinities into full fleged goals.

Here goes my article:
Art of Household Refrigeration
The refrigerator is perhaps the highest electricity consuming device in our homes. A major portion of our electricity bills is due to this and considering the number of refrigerators in India at present it can be easily be inferred that refrigerators are eating up a very high percentage of electricity of the country.
We therefore need to look up to how we can maintain our refrigerators and thus save energy by implementing some simple ideas into practice.
1. Open the refrigerator door sparingly, as every time it is opened cold air inside is replaced by the hot air outside which needs to be cooled. This results in compressor doing more work and thus adds to the electricity consumption significantly.
2. Hot items should be first cooled to room temperature before putting them in the refrigerator. This helps minimising compressor work.
3. Condenser coils behind or beneath the refrigerator should be cleaned once or twice a year as dust and grime insulates it from the surroundings and lowers the refrigerator efficiency.
4. Check door for door gasket air leaks. This can be done by putting a flashlight into the refrigerator and looking for light leaks. It is worth mentioning that door gasket air leaks account for a third of regular heat load of the refrigerators, and thus any defective door gaskets must be replaced immediately.
5. Avoid unnecessarily low temperature settings. Ideal temperature setting for the freezer is -18oC and that for the refrigerator is 3oC. Not adhering to this limit can increase electricity consumption by more than 25% !!
6. Avoid excessive ice build up in the interiors of the evaporator, ice insulates the interiors from the refrigerant and thus decreases efficiency. One should go for a frost free refrigerator if buying a new one.
7. Use the power-saver switch that controls the heating coils and prevents condensation on the outside surfaces in humid environments. The low wattage heaters are used to raise the temperature of the outer surfaces of the
refrigerator at critical locations above the dew point in order to avoid water droplets forming on the surfaces and sliding down. Condensation is most likely to occur in summer in hot and humid climates in homes without air-conditioning. The moisture formation on the surfaces is undesirable since it may cause the painted finish of the outer surface to deteriorate and it may wet the kitchen floor. About 10 percent of the total energy consumed by the refrigerator can be saved by turning this heater off and keeping it off unless there is visible condensation on the outer surfaces.
8. Give the refrigerator some place to breathe!! Blocking air flow to the refrigerator hampers the performance of the condenser and thus decreases efficiency.

Journey Delayed by 15 hrs.
Punctuality: the virtue admired by all of us is almost absent in Indian Railways. It was the day ,when I was to leave Varanasi to be at Dhanbad.
Arrival time of the train was 9:00p.m.It was initially delayed by 10 hrs. This meant that there was going to be no trace of 3308 till 7 morning. At least!
I returned home only to be back at station at 6 morning next day. There I learnt that there was further delay of 2 hrs.
Winter nights usually extend to 7 a.m. Inspired by Harsh Mander ,I took this opportunity to observe the dark underbelly of city residing on platforms.
Most beggars were sleeping at that time. Some were awake to start a new day.
I overheard a conversation among a group of 3 beggars.
Beggar 1: Hurry up you two bozos. Mahanagri Express is about to arrive in 10 minutes.
Beggar 2(shocked):What?Let’s move to platform 4 soon. It carries a lot of passengers & foreign tourists too.
Beggar3:OK.Afterwards we will move head for Rajdhani on platform 1,it also pours in a lot of tourists.
Beggar1:Good! Each one of us will make about 300-400 today.
They moved swiftly to platform 4.
My mind echoed their words. My God! Begging provides oneRs.300 a day. Damn it. Is this what Harsh Mander called ‘the dark underbelly’?No work altogether!Just go to people ,cry and pocket the money! They even don’t seem to care about their future generations.They drag them too into it.One could make a decent life with 300 rupees in a city like Varanasi.Where do they spend the whole money?
An announcement broke my thought process.The train was further delayed by 3 hrs.It meant a total delay of 15 hrs.3308 will arrive at 12 noon.So,it was the time to yawn and curse Indian Railways.
Suddenly I was worried about my luggage. I forgot about it during the whole process. Thankfully, it was safe near the bench some yards away. Nobody had touched it.
A child beggar came to me, begging for a rupee. I abused him to move ahead.
