Shahbag Movement: The Audacity of Youth

2013-02-19T13:08:00.003+06:00

Starting with the audacity of youth, Shahbag Movement (the Movement) is nothing but the outburst of a long-pending dissatisfaction of the people of a country for fair trial against war-crimes. The Movement is not for revenge, and it is not against any particular religious-believe. The Movement is to confirm the justice for the crimes against humanity which has been delayed for more than four decades. The Movement is to bring-back the spirit of 1971 war of independence. The Movement is to re-write the history of Bangladesh.

The demand of Shahbag Movement is very clear and simple - ‘ensure capital punishment for the war-criminals of 1971’. At the same time, ‘the war-criminals should not be allowed to be organized with political, financial or social establishments’. And the ‘people’ of the country has endorsed the demands.

The Movement is not going to say how the demands will be full-filled, but it has already established the points. Now, it is the responsibility of the representative of the ‘people’ or the ‘law-makers’ to fulfill the expectations; they have to figure-out the solutions to the loopholes of the whole judiciary and other relevant systems. Let us remember again that ‘law’ is for ‘people’, and it is the ‘people’ who has the right to change the ‘law’. The ‘law’ of any land should reflect the expectations of the ‘people’.

Yes, the Movement is not merciful to war-criminals. But, this is not against human-right. Rather, it is upholding the international human-right by ensuring fair trial for the crimes against humanity. Therefore, it could be said without any hesitation that ‘Shahbag protesters are more humanitarian than the so called human-right activists in the west and east who are trying to portray the Shahbag Movement as fascist’.

The Movement should not be distracted with all of the noise around it. Those, who are deliberately supporting the war-criminals for many different reasons, will continue to raise many tricky issues. But, ‘the main thing is to keep the main thing as the main thing’. And the main thing for the Movement is the demand of ‘ensuring capital punishment for the war-criminals’. As long as the ‘people’ is with the Movement, and ‘youth’ is leading it, no evil power can destroy the spirit of it.

Time will say what would be the final outcome of the movement. However, the best achievement has already been attained – the YOUTH of the country has showed their AUDACITY to stand against injustice. With this great achievement, the nation will be on the right track at least for the next few decades.

Solidarity to Shahbag Movement! Salute to the youth for their audacity to stand for justice! Salute to the ‘people’ of the previous generations who have contributed for decades by keeping the spirit of liberation war alive by sharing true stories, hope and believes to the new generation. And finally salute to the all ‘human-being’ in home and abroad who are supporting the Movement in any form.

Let us all wish and hope that those, who are still not sure about the Movement, will be enlightened enough to realize the major shift in the history of Bangladesh – they will be beside the truth and justice.

Night Lights of Bibiyana Gas Field, Bangaldesh

2013-01-26T19:42:00.002+06:00

Night Lights of Bibiyana Gas Field

Bibiyana Gas Plant, which is producing more than 30% gas of Bangladesh at present, is one of the remarkable features in the night lights of North-Eastern Bangladesh. It appears that the Bibiyana Gas Plant's light is brighter than that of Sunamganj, one of the districts under Sylhet Division. It is also visible in the night light map of Bangladesh as well.

Bibiyana is expected to be larger than the initial estimates. Chevron, the operator of the gas plant, is going to invest additional 500 million dollars which is said to the single largest foreign investment in Bangladesh.

The original image was taken by the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite in any day between April 2012 and October 2012, and has been copied from NASA's Earth Observatory website (Night Lights 2012 - Flat map). This map has been created by annotating the original image in Google Earth (with international boarders) and Power Point (with labels).

হাতের লেখা ‘সুন্দর’ করার সহজ উপায়

2012-03-23T11:24:00.001+06:00

সত্য বলতে, হাতের লেখা ‘সুন্দর’ বা ভালো করা মোটেও কোন কঠিন কাজ নয়। হাতের লেখা ‘সুন্দর’ করতে মূলতঃ যে তিনটি বিষয় প্রয়োজন সেগুলো হলো:

১.‘সুন্দর’ করে লেখার বিষয়ে নিজের আগ্রহ বা ইচ্ছে থাকা,

২. হাতের লেখা ‘সুন্দর’ করার সঠিক ও সহজ কৌশল বা উপায় জানা, ও

৩. নিয়মিত হাতের লেখার চর্চা করা।

হাতের লেখার মাধ্যমে বোঝা যায়, মানুষের মনোযোগ, স্থিরতা ও চিন্তা করার ক্ষমতা। ‘সুন্দর’ হাতের লেখার প্রশংসা সবাই করে। আর হাতের লেখা ‘সুন্দর’ হলে পরীক্ষায়ও ভালো নম্বর পাওয়া যায়।

নীচের পরামর্শগুলো অনুসরণ করলে হাতের লেখা অবশ্যই ‘সুন্দর’ হবে।

· প্রতিটি অক্ষর বা বর্ণ স্পস্ট হতে হবে, যাতে আলাদা-আলাদা ভাবে বোঝা যায় যে, ঠিক কোন অক্ষর লেখা হয়েছে। বাংলা লেখার ক্ষেত্রে, মাত্রার সঠিক ব্যবহার করতে হবে। ইংরেজির ক্ষেত্রে ‘ক্যপিটাল’ ও ‘স্মল’ লেটার সঠিকভাবে লিখতে হবে।

· লেখার স্টাইল বা ধরণ (যেমন, সোজা/খাড়া বা বাঁকা/কাত) যে রকমই হোক না কেন, অক্ষরগুলোর আকার ও আকৃতি একই রকম হতে হবে। অক্ষর ছোট-বড় বা মোটা-চিকন করা যাবে না।

· এমন কিছু অক্ষর আছে যেগুলো সঠিকভাবে লিখতে পারলে অন্য অনেক অক্ষরও ভালো ভাবে লেখা যায়। যেমন, ‘ব’ সুন্দর করে লিখতে পারলে আরো লেখা যায় ‘ক’ ‘র’ ‘ধ’ ‘ঝ’ বা ‘ঋ’। আবার কিছু অক্ষর-এর অংশ বিশেষ ব্যবহার করা যায় অন্য অক্ষর-এর মধ্যে।

· শব্দ লেখার ক্ষেত্রে অক্ষরগুলোর মধ্যে কম কিন্তু সমান দূরত্ব রাখতে হবে। প্রতিটি শব্দের মধ্যে কমপক্ষে একটি অক্ষরের পরিমাণ দূরত্ব থাকতে হবে।

· অবশ্যই লাইন সোজা হতে হবে। লাইন সোজা করতে শুরুতে দাগ টানা খাতায় লেখা চর্চা করা যেতে পারে।

· লেখার কগজের বামে, ডানে, উপরে ও নীচে সঠিক মার্জিন রাখতে হবে। প্রয়োজনে, ভাঁজ করা অথবা দাগ টেনে নেওয়া যেতে পারে।

· কোনো শব্দ বা লাইন ভুল হলে তা এক দাগে কেটে দিতে হবে। বেশী কাটাকাটি করা যাবে না।

· দাঁড়ি, কমা, সেমিকোলন, ‘আ’কার-‘ই’কার ইত্যাদি ছোট ছোট অংশের প্রতি নজর দিতে হবে। বিন্দু বা গোল চিহ্ন-গুলো সঠিকভাবে গোল করতে হবে।

খেলাধুলা বা পড়ালেখার মত, হাতের লেখা ভালো করার ক্ষেত্রে নিয়মিত চর্চার বিকল্প নেই। প্রথমে আস্তে আস্তে ভালো করে লিখতে হবে। পরবর্তীতে দ্রুত লিখলেও লেখা ভালো হবে।

FrictioNRG: Another Form of Renewable Energy

2010-10-04T00:47:00.001+06:00

Background
Someday in early 2008, I was traveling in an SUV (Sports Utility Vehicle) from Dhaka to Moulavi Bazar (in Bangladesh) for a field visit. One of my colleagues, who was a Geophysicist, was also accompanying me in the trip. It was about 7-8 hours journey and we were talking most of the times. Discussion topics were diverse and one of the topics was alternative energy. At that point of time oil price was in its pick, probably about 150 US$ per barrel.

All of the windows of the car were closed as because the AC was on. However, for some reason, the driver opened an window while the car was moving at about 80 km per hour. So, a huge blow of fresh air entered in to the car and splashed in to my face. Suddenly I realized that our car is generating huge amount of friction with the air! In other words, if I was out of the car and sitting or standing somewhere in the same spot of the road, I might not feel that much of air speed. But while the car was moving at a certain speed it was creating a friction with the air and that’s why the wind speed was much higher around the moving car. I also discovered that every single car running on the road is creating frictional energy but that is fully untapped!

Another example came to my mind. In our childhood, we used to play with pinwheel (locally known as “Chorki”, a paper made flower like small fan attached to a bamboo stick, kind of small wind mill). We just hold the pinwheel against wind and it rotated. That was fun! But sometime, wind was too slow. And then we had to run to rotate the pinwheel! That means we created frictional energy just by running and used it!

Basically, from that day I was thinking about frictional energy and realized that frictional energy is being generated all over the world while we are running any vehicle and still now it is quite untapped. But, we used it to power pinwheel in our childhood! Can we use it to run a vehicle? Well, probably yes!

From now onward, I would like to call this energy as “FrictioNRG” – here “NRG” should be pronounced as “Energy”.

Tapping FrictioNRG to run a car
A car generates FrictioNRG all the times while it is moving at any speed. Now if there is a pinwheel on top of a car, it will be rotating! The rotating pinwheel or turbine could be attached to a dynamo to generate electricity. And then the electricity could be used directly or indirectly (by storing it in battery) to run the car. There might be number of micro turbine on top of a car so that more electricity could be produced.

The car will generate more electricity if it is running at higher speed. At certain speed, probably the car will be running just using its FrictioNRG. To start and run the car at lower speed, stored energy (from previous run) or a traditional fuel source could be used. If it is possible to install solar panel on the top, the car could probably be run without any traditional sources.

So, what I’m proposing is that a car can run by using its own FrictioNRG, given that it is obtaining certain speed using another source of energy.

FrictioNRG could be used to run any vehicle
If it is possible to tap FrictioNRG for a car, the technology then could be used to run any type of vehicle. All forms of transportation, i.e., train, bus, truck, aircraft, ship and even spacecraft, can use the same technique.

Energy saved is energy found
I’m not a scientist by profession. But, as a rational individual, my understanding is that it would not be too difficult to realize the idea of tapping frictional energy for a car. And if it is possible to invent the technology, a significant amount of petroleum could be saved. As it is being said that “energy saved in energy found”, I believe it would be a good area to explore as a source of another alternative energy for the future.

The challenges ahead
There are number of challenges to realize the idea. First of all, further study is required to understand how much FrictioNRG could be tapped using micro turbines installed at the top of a car considering the variation of car speed and battery capacity. Secondly, the vehicle should have an energy switching and controlling option. Thirdly, the technology should have to be cost effective and easy to install. If it is possible to integrate the technology for existing vehicles, that would also be a great achievement.

Opportunity for collaboration
I have already shared the idea informally with some of my friends and colleagues and received some positive feedback. Now, if any individual or company would like to initiate a project on FrictioNRG, I would be happy to be involved in that project.

For further questions or comments please contact me directly by sending an email to Palash.Basak@gmail.com or info@frictioNRG.com or FrictioNRG@gmail.com.

Correlation

2010-06-11T22:43:00.000+06:00

Few days back my wife taught our daughter, who is about 25 months old by now, that “PET” (a Bangla word) in English is “belly”. Today my wife questioned our daughter again to understand whether she can still remember the English term for “PET”. Unfortunately my daughter forgot the exact English word but she replied promptly that it is “SHAPLA”! (Probably because, she was taught earlier that the English term for “SHAPLA” is “lilly”!) What a correlation!

My Handheld GPS

2009-04-19T15:30:00.005+06:00

I got questions from some of my friends about GPS. Then I thought it would be good to share some information about my own GPS to all of you.

I have a Garmin handheld GPS which I have been using for about four years. I found it quite useful during my personal and official trips in home and abroad. During my trip in Durham, UK, the GPS helped me to find out my hotel (a small cottage) in a very windy, cold and dark night. The area was basically out side the main town and less densely populated. Without the help of my GPS it would be very difficult for me to find the place at that night!

For those who are not familiar with the term - GPS stands for Global Positioning System. GPS can help you to understand your location anywhere in the world using signal from number of satellites. Now a days GPS is being used for variety of purposes, including personal and vehicle navigation, mapping, fishing, trekking, etc.

Garmin is the pioneer in handheld GPS. The model I have got is eTrex Legend HCx. It has a color monitor. This is little better than the basic models. So far I remember, the price tag was about 290 USD but I bought it from Jakarta, Indonesia. If you want to buy this product from Bangladesh, I believe, the cost will be higher than that.

Click here to find our more information about this GPS model. If you are interested to learn more about other products of Garmin, click here.

As I'm aware of, there are only few organization who sell GPS. Several models of Garmin GPS is available at Haroon Enterprises Ltd. (62, Purana Paltan(Opposite to Doinik Bangla), 1st floor, Dhaka 1000, Tel: 9560577). Overseas Marketing Corporation (Pvt.) Ltd. (Unique Trade Center ( UTC ), 15th level, 8 Panthapath, Dhaka - 1215, Tel : 8154510-11, 8156837) also have some handheld GPS but those are from Magellan. Click here to visit Overseas Marketing Corporation's website.

Do you have any other specific question about handheld GPS? Let me know. I can try to answer.

Electricity from Pathar-Kuchi

2009-02-04T11:51:00.005+06:00

I was amazed to read an article in Jugantor on 2nd February 2009. According to the article, electricity could be generated from Pathar-Kuchi, an indigenous plant of Bangladesh. I don't know the scientific name of the plant.

It was claimed that substantial amount of electricity could be generated with the technology proposed by Dr. Kamrul Amal Khan, Chairman of the Department of Physics of Jagannath University and three of his associates. They explained in a seminar in Dhaka that 60-100 megawatt electricity could be generated from Pathar-Kuchi produced only from one acre of land.

Bangla Speaking Community is in every part of the world

2009-01-11T11:46:00.000+06:00

While I was visiting the website of OmicronLab to download a Bangla Typing Software, Avro Keyboard, I have found an interesting map showing the visitors of the site. The map clearly shows that Bangla Speaking community (both from Bangladesh and India) is present in every part of the world!

Throughout 2008, there were over 1.6 lakh (0.16 million) visitors in the site. People from 172 countries visited the site. About half of the visitors came from outside Bangladesh or India.

If you consider visitors by country then India is the top (about 48,000). More than 34,000 visitors were from Bangladesh. United States, United Kingdom, Saudi Arabia, Canada, Australia, Italy, Japan, Germany, United Arab Emirates and Malaysia are in the top list of the visitors.

You can find details about the visitors in the following link

In the last page of Prothom Alo today (6 Jan 2009), an article has been published on "Neel Shaluk". The author (Sourav Mahmud) wrote a nice introduction of the flower and put a picture which was captured from Boga Lake, Bandarban.

While traveling to Kuakata in September 2008, I took a picture of the same flower from a road side water-body somewhere in between Mohipur and Kuakata.

The flower is really beatiful.
