সপ্তর্ষির বিপরীতে

                                  নির্ঝর চক্রবর্তী

সপ্তর্ষির বিপরীতে যে কালপুরুষ ডানা মেলে উড়েছিল
                        আজ সে পথ চেনাবে ----

চেনাবে নতুন দিগন্ত
তুষার শুভ্র মরুভূমি,
হাড় হিম শীতল বাতাস,
আর তারই নিচে অদম্য জীবন সংগ্রাম
পৃথিবীর সবথেকে সজীব প্রাণভূমির I
বলবে রুকারি থেকে ডিম চুরির অমর কাহিনী,
শোনাবে একদল বীরের কথা,
উন্মুক্ত কন্ঠে ঘোষণা করবে জীবনের জয়গান,
হার না মানা মানুষদের কথা I

মনের জানালা দিয়ে উঁকি মেরে দেখো -----
কোনো হাড় হিম দীর্ঘ সন্ধ্যেতে
তুমিও হয়ত হেঁটেছিলে ঐ তুষারদেশে -----
ক্ষতবিক্ষত হাতে আগলে ধরেছিলে প্রিয়তম সাথীর
অসার দেহ, মরুঝরের তান্ডব থেকে,
সপ্তর্ষির বিপরীতে I

বন্ধু আজ আবার এসো ----
জীবনের জয়গান গাও, মানুষের জয়গান গাও I
কালপুরুষ আজ আবার পথ চেনাবে তোমাকে ----
শুধু তোমাকে I
কারণ তুমিও বীর,
তুমিও পারো বরফের ভেলায় ভেসে
              দীর্ঘ শীত কাটাতে ----
তুমিও পারো অভুক্ত শরীরে
সহযাত্রীকে খাবার ভাগ করে দিতে I

কালপুরুষ তোমাকে পথ চেনাবে ----
কারণ তুমিও পারো জীবনের জয়গান গাইতে ----
সপ্তর্ষির বিপরীতে I

Note:
সপ্তর্ষির বিপরীতে means opposite to arctic. Ancient Greek people used to believe that there was a continent at southern part of the earth which balances the northern continents. They had named that imaginary continent as Antartikos, which means Opposite to Bear (“Ant” means “opposite” and “Arktik” means “Bear”). Bear is the cluster of stars visible from northern part of the earth, which is known as “Saptarshimondal” (সপ্তর্ষিমন্ডল) in Bengali.
Later on, during 16th century AD, that continent of south was discovered. Name of that continent is Antarctica. It is cold, dangerous, beautiful and unapproachable by normal means. Some adventure lovers and scientists had explored the mystery of that iceland with lots of pain and sacrifices. This poem is dedicated to those adventurous heroes (like Scott, Wilson, Shackleton, Amundsen, Ross, etc.) who contributed their life to discover the mystery and science of that wonderland, called Antarctica.

গাঁয়ের শেষে পাঠশালা


            নির্ঝর চক্রবর্তী

গাঁয়ের শেষে পাঠশালা
ঘরটি তার আটচালা
ছাত্ররা সব হরবোলা
মুখে তাদের নেই তালা I

হেডমাস্টার পতুবাবু
গোলগাল কমলালেবু
ঘুমেই শুধু হাবুডুবু
অঙ্ক দিলেই হ'ন কাবু I

স্কুল বসে দশটা দশে
গ্রাম থেকে ছেলেরা আসে,
খেলতে তারা ভালবাসে,
লাঠির ভয়ে পড়তে বসে I

পতুমাস্টার ঘুম দিলে
পড়ার কথা যায় ভুলে,
ডানপিটে সব ছেলেপিলে,
মেয়েদের মন পুতুলে I

সবাই বলে "চল পালা"
চারটেয় পড়বে তালা,
ছুটির পর আরো খেলা
গাঁয়ের শেষে পাঠশালা I

একরাশ কালো কালো ধোঁয়া

                       নির্ঝর চক্রবর্তী

একরাশ কালো কালো ধোঁয়া I
কল কারখানা থেকে  উড়ে উড়ে
                     ভেসে যাওয়া,
একরাশ কালো কালো ধোঁয়া I

চোখ কান মুখ বুজে
জামা প্যান্ট শার্ট গুঁজে
অফিসের পথে হেঁটে যাওয়া,
একরাশ কালো কালো ধোঁয়া I

নগরের সভ্যতা আমাদের গৌরব
ধোঁয়াসার অনন্য অদ্ভূত সৌরভ
কোথায় হারিয়ে গেল শাল শিশু মহুয়া,
চারিদিকে একরাশ কালো কালো ধোঁয়া I

Gear Box: Fundamental, Operation & Maintenance

Gear always attracts classical engineers, because, gear revolutionized the human civilization. Gear is the most classic contribution of classical science. With gears motion can be controlled with infinite accuracy. Varied change of speed with utmost accuracy, varied change of direction with finer control is possible only with gears. Even converting rotating movement into linear motion and vice versa can be obtained by different gearing combinations.


The following presentation is made to give a basic concept about gears and gear boxes.

In common industrial practices, normally open gears are not used. In most of the cases, gears, either one set of gears or a series of gears in gear train, are operated in a casing, which is known as gear box.

This presentation may help engineering students and fresh engineers to get an overall idea of industrial gearbox. Also it can be helpful for practicing plant and operation engineers who want to refresh themselves about basics of gearbox.

Welcome to Politics

April, 2011, election time at Eastern part of India. West Bengal is plunged into politics, as usual! Politics is in the air!

What is politics?

I can remember my early college days. It was monsoon at Jalpaiguri. In engineering, we had a subject called Civics, where politics was a topic. Our civics teacher used to explain everything with minute details and after that he used to ask “is not?” in his typical Bengali accent. We used to call him “is not” sir, with love. One day “is not” sir asked us, “What is politics”? All the boys and girls were explaining their definitions. And suddenly one of our friends with curly hair stood up and answered with his typical chuckling smile “politics is a first class game played by the third class persons”. The whole class started laughing, and so was “is not” sir.



Cartoon by Nirjhar
  In my early childhood, when I was a mere kid, I had immense interest and awareness about politics, which is quite unusual for a middle class Bengali family. Still today, I can remember the political cartoons of great cartoonist Kutty, which was a regular publication in a popular Bengali Newspaper (Aajkaal), during late 80s. Inspired with those cartoons, I had drawn a hen with a face of Michael Gorvachov (last communist president of Soviet Union) with his two eggs named “glasnost” and “perestroika”! And behind that I had drawn comic face of Yeltsin (first head of nation of democratic Russia) who was smiling at the hen! Those were golden days of my life, when I used to enjoy study, politics, cartoons, recitation, and sports of all possible kinds! But as I grew up, I started feeling that politics in India is nothing but a circus and politicians are clowns of that show only. Even clowns at real circus are human being with real heart. But Indian politicians are “heartless” “inhuman” clowns! Nobody is exception, starting from Municipalities to Parliament! Indian politicians are different species, compared to Homo sapiens. I wish that, someday some scientist will discover the actual species of Indian politicians and the mode of mutation of a human gene when an Indian enters into politics.
As per great Bengali writer, Tarapada Roy, politicians are well aware regarding people’s thought about them! Mr. Roy used to know a politician in rural areas. One day Mr. Roy went to that area to attend a social party. After dinner he was standing beside the dining place. Suddenly that politician came for dinner, with his company. After seeing Mr. Roy he came to him and introduced himself to Mr. Roy. Then Mr. Roy told him “Yeah, I have heard lot of things about you.” Suddenly the politician replied with his changed stiff jaws, “Whatever you have heard, nobody can prove anything”! Then he left the place with firm steps! That is a politician!

But in reality I have found that, some people are there who has tremendous interest in politics. They “Eat Politics, Drink Politics, and Sleep Politics”! Like my old neighbor, Senbabu. He is strong supporter of a political party, whose theme color is blue. But, he is neither a member of that political party nor that party cares him. He is just a middleclass Bengali office employee, who mugs up popular Bengali news paper, “Ananda Baazar” at morning with a cup of tea and goes to the office by crowded local train. During short train journey he discusses major political news with his like minded friends, in a high voice. He always loves to establish his views, by any means. After going to office he vomits all of the words written in the news paper in a sharp voice, standing on the office floor. Obviously he focuses on that news which favors blue colored party. After announcing all the political news in his style, he feels comfortable and takes his allocated seat. After that he starts discussing and analyzing all the news with his next seat neighbor Palbabu, in a low voice. Sometimes he raises his voice that much so that his possible rival Banerjeebabu can hear his views. In the process clock turns to 12-30 PM. Lunch break. During lunch break Senbabu finishes his all possible calls to his relatives, friends and his share broker. After lunch Senbabu again delivers his second lecture on the office floor by explaining the present socio-political and economic scenario of West Bengal. He also analyzes how the blue colored party is developing the state and how the major opposition of blue party is destroying the state. But there is a major difference in his morning lecture and afternoon lecture. His morning lecture is always very flamboyant, aggressive and news based. But his afternoon lecture is more analytical and subjective. He delivers morning lectures with high voice and high frequency; where as his afternoon lecture is more calm and composed. His calmness depends on the quality of the lunch! After this second round lecture, he spends the second half by visiting chairs of his possible like minded friends by collecting their views on his lectures. When the smaller stick of the clock touches 5, Senbabu leaves office before the slimmest stick of the clock starts moving, after 5-00 PM! On the return journey, Senbabu normally does not discuss anything, because due his tough professional life he feels tired and prefers to sleep during return journey! Nowadays, I am observing that, Senbabu is traveling in an office bus. Most probably his office has started a bus service. God, please save his colleagues who travel with him!


Cartoon by Nirjhar
  Now please come to Palbabu, Senbabu’s next table neighbor at office. Palbabu thinks that he is smarter than Senbabu. He is not that vocal as Senbabu. But he continuously supplies data to Senbabu for delivering lectures. Senbabu is also a strong supporter of Blue coloured political party, but he is member of Yellow coloured political party at his locality and takes all the helps from present ruling Pink coloured political party through his nephew who is high level leader of Pink coloured party! When somebody asks Palbabu about the reason behind his supports for Blue party, he always tells that he is not a supporter of Blue party, he only supports the truth!
This truth is very dangerous. Most interestingly, when politicians demand something, he always insists that his version is as true as the universal truth. One day, in a election campaign a popular lady leader of opposition demands that if she wins she will make her state Switzerland. After her lecture, her close aide, Mr. Madanlal, asks, “M’am, we have told that you will make this state Switzerland! But after your win, if people ask you about this then what will happen”? The lady just ignored, “Oooo! People have short memory. They will never remember this!” Mr. Lal was still nagging, “M’am, if Opposition raises this issue, and try to mobilize people, then what will happen”! Now the lady became a little irritated and replied in her usual tone. “You fool! In my tenure I will constantly demand to Central Government to cover whole the state with Himalayan range! Before next election if somebody tries to make this an issue, then I will prove that, it was a great conspiracy of Central Government by not supporting my demand”! The politicians write history by their own pattern, create geography by their own wish, and discover new species by their own intellect. They make their own rule of game and break the rule by their own! One day, in a press conference, the most unpopular chief minister of a state boasted that his party is the best alternative after the completion his five years term. The reporters asked him that, his party is ruling party. How can an incumbent be its own alternative? The chief minister laughed, “I have washed out all the opposition! So nobody can be alternative for me, except me”!

Cartoon by Nirjhar

I want to finish my essay with a story written by great writer Tarapada Roy. Once upon a time, a politician went to a famous but controversial gentleman with a request to deliver a lecture on his behalf. The gentleman instantly agreed with this proposal and promised to help the politician, but he just requested him to ponder over, “before I deliver a lecture for you, go home and please rethink what will be beneficial for you: in case I lecture for you or I lecture against you”!
___________________________________

Last but not the least! Again Mr. Tarapada Roy:

It is a story of a very old village lady.

A politician came to beg for vote to that old lady, “Grandma, please give me vote in next election!”

The old lady had good vision, also her memory was as sharp as a young fellow, “You were an election candidate last year also! Is not it?”

The candidate, “yes Grandma!”

The grandma was bold, “then why you have come again, within a year!”

The candidate, “The government falls in trust vote!”

The old lady asked, “Why you allow government to fall!”

The candidate had no reply.

The old lady asked, “Again you are begging vote?”

The candidate was smart, “I know you will give me vote. I am sure!”

The lady, “this time, I will keep you in second position.”

The candidate fumbled, “Grandma, who will be your number one candidate?”

The old lady boldly replied, “Anybody, except you!”

************************************
The grandma was absolutely correct. That’s how an Indian politician should be treated! Do you agree with me?

Raw Material In Iron Making

In this presentation, I have tried to explain main raw material sources of iron making process. Also, with my experience, I have tried to give a concept about the plant engineering related to raw material. I hope that, this presentation will be helpful for young engineers. With this presentation they will get a broad idea about the raw material used in iron making.

Golden Jubilee celebration of Jalpaiguri Government Engineering College: Alumni Meet


Welcome to Alumni Association of Jalpaiguri Government Engineering College
On 12th March, 2011, around 250 ex-students of Jalpaiguri Government Engineering College (JGEC) had visited the college premises. The occasion was Annual Re-union program. 2011 is very special for JGEC, because the college is celebrating golden jubilee in this year. The re-union program was in the evening. The program was inaugurated by Principal Professor Jatyirmay Jhampati. Professor Jhampati is also ex-student of the college and member of official alumni.
 
Dr. J. Jhampati addressing at Alumni Meeting
In the morning, lots of ex-students were present in the college seminar hall to attend the official alumni meet. The program was anchored by Mr. Gautam Bhaduri (1983 batch). Mr. Bhaduri is the secretary of the alumni. Dr. Jhampati also was present in this morning meeting.
 
Alumni Meeting at Seminar Hall
Dr. Jhampati had explained the future plan for college, and also had stressed on the college-alumnus relationship. Mr. Tapas Saha, who is one of the head of current Durgapur-Asansol Alumni, had also delivered his lecture. He had told about the importance of centralized alumni having head quarter at college premises. He also explained the possible relation and interaction between central official alumni and present local alumni at various places. All the members of the meeting had agreed that the official alumni will be the core; whereas present various local alumni will work as branch or chapter under the umbrella of official central alumni. The various local alumni will organise local get together and social activities in the locality, whereas the central alumni will act for direct development of the college and its members.

It was also discussed that, if any local alumni do not want to accept the official alumni, then what will be role of official alumni. Mr. Gautam Bhaduri had given me opportunity to deliver lecture in the meeting. Regarding conflict between official alumni and any local chapter, I had pointed out that, any local alumni have limited membership. But by virtue of its official presence, the newly formed central official alumni will be able to generate a huge membership, and in long run all the future generation will become member of official alumni. So, there will be a time, when the local alumni which do not support official alumni will cease or become microscopic minor. So at present it is better to avoid any conflict with any local alumni which do not accept official alumni. Because, ignoring conflict is also a method of avoidance of conflict. All the members were agreed with this view.

Some near future activities of alumni will be as follows:

1. Alumni will generate a web page, where ex-students can directly enroll their names as a member. 1992 batch ex-students had started this discussion, which all the members also had supported.


2. Alumni will organize re-union program of ex-students in future.

3. Alumni will guide final year students for job related issues.

4. Alumni will co-ordinate with all existing chapters of alumni, which are situated at different parts of the globe.

5. All ex-students can directly contact alumni for any college related issues.

Arnab Guha of 2000 Batch had pointed out that, when a student will complete his study and go to any city for further assignment, then alumni can provide him contact of ex-students who are already present in that city and who may guide him about that city. Also he had suggested alumni to think the possibility of economic help to just pass out students for a given short period.

Ex-students from different batches had delivered lectures and had opined on various issues. All were fascinated with the attendance of this reunion program. 1985 batch ex-students had a huge presence in this whole show.

Also, many ex-students had explained the role of alumni to spread the name of college to the out side world. Many newly formed colleges, despite of their lower education quality, are able to advertise themselves. But it is true that, 50 years old JGEC, which is the only government technical graduation school of vast area of North Bengal, is not able to advertise itself in accordance to its status.
 
Present office of Alumni Association Head Quarter
At present the alumni has an office at first floor of college building. Mr. Gautam Bhaduri has appointed an office assistant (popularly known as Nimuda by college students). At present any ex-student has to pay one time Rs. 100 to get a life time membership.

At evening, all the ex-students were present on football ground; just beside the ladies hostel. They had gathered in the ground to attend a football match between alumni members and present students. Many ex-students had refreshed their old skills on the field. It was a great fun. The ex-students, who were tired with their present tough schedule, had enjoyed the fun with the memory of their golden past.
 

On the field, refreshing old skills

After the great football match, the reunion committee under the leadership of present final year student, Hasan Mustafa, had invited the ex-students at Oval ground for a great facilitation program. The program was started with a show by the students of night school which is run by present JGEC students. Present JGEC students run a night school where under privileged boys and girls get free education. From first batch (1966 pass out) to last batch (2000 pass out) students ware present in this facilitation program. All were amazed to see the first batch students. Many ex-students also had come from abroad to join this program. The final year students had given me the opportunity to co-ordinate that great show, for which I am extremely thankful to him. It just reminded me the college days, when I used to anchor many shows, including our great skit (short drama) shows.

Here we are, once again (1996-2000 batch)
After the facilitation program, there was dinner party at 4th year hostel canteen. It reminded me the taste of ID (ideal dish), after a long time. Old college staff, popularly known as Punditji, had come to the canteen to meet old geniuses. At present, Punditji's son, Nabin is taking care canteen of hostel no. 3.

Once again, in old mood

Adda at common room, masti in front of dining room, thek at hostel rooms…suddenly all became reality once again.
 
No more syllabus pressure! Thank God!
All the ex-students were extremely nostalgic. Everybody had left these good old lanes, but these lanes will never die in their memory…because JGEC is present in their sole, forever……. forever.
