Haor or Majhe Siyal Raja....
«on: 06/19/04 at 01:03:32 »

Heard about the gr8 shyleti proverb....."Haor or majhe siyal Raja".....What is an Haor....? Mohd Shamsul Alam and Md Sazzad Hossain explains. Itao kintu...cut paste....haasio naa....

Haor bowl-shaped large tectonic depression. It receives surface runoff water by rivers and khals, and consequently, a haor becomes very extensive water body in the monsoon and dries up mostly in the post-monsoon period. In Bangladesh haors are found mainly in greater Sylhet and greater Mymensingh regions. During monsoon a haor is a vast stretch of turbulent water. The word haor is a corrupt form of the Sanskrit word Sagar (sea). In Sylhet and northeast Mymensingh, the people pronounce the Bangla letter ৸স৹ (sa) as ৸হ৹ (ha), and some times ৸গ৹ (ga) as ৸হ৹ (ha). Thus sagar is sounded haor.

The haors are of tectonic origin and possibly connected with the rise of madhupur tract. beels do not subside but haor basins do. In its original form, the haor basin comprising the floodplains of the meghna tributaries would have consisted of a rich mosaic of permanent and seasonal lakes and ponds with abundant aquatic vegetation. But through gradual sedimentation, the basin becomes shallower leading to the formation of reeds and sedges. This resulted in providing enough food and shelter for fish and other aquatic, fauna and attracted the migratory birds which, in their turn, added to the fertility of the waterbodies by their excreta promoting rich growth of phytoplankton and macrophytes thus partly contributing to the process of eutrophication.

The haor basin is bounded by the hill ranges of Meghalaya (India) on the north, the hills of Tripura and Mizoram (India) on the south, and the highlands of Manipur (India) on the east. The basin includes about 47 major haors and some 6,300 beels of varying size, out of which about 3,500 are permanent and 2,800 are seasonal. Numerous rivers rising in the hills of India provide an abundant supply of water to the plains and cause extensive flooding during the monsoon upto a depth of 6m. Small permanent water bodies within the haors are called beels, which occupy the lowest part of the depressions. During the dry season, most of the water drains out leaving one or more shallow beels which become mostly overgrown with aquatic vegetation or completely dry out by the end of dry season exposing rich alluvial soils extensively cultivated for rice.

The surma and kushiyara in association with other minor hilly streams like manu, khowai, Jadhukata, piyain, Mogra and Mahadao form the dense drainage network of the haors. The rivers are primarily responsible for providing inputs - rainwater and sediment load to the plains including haors. The plains remain flooded for about 7 to 8 months. During the rainy season, the haors turn into a vast inland sea within which the villages appear as islands. Occasional high winds during July to September generate large waves in the haor, which may cause considerable damage to homesteads.

The entire Sunamganj district, major portion of Habiganj district, some parts of Sylhet Sadar upazila and Maulvi Bazar district are covered by many haors. In greater Sylhet the most prominent haors are Saneer haor, Hail haor, Hakaluki haor, Dekar haor, Maker haor, Chayer haor, tanguar haor, and Kawadighi haor.

The haors are considered the most productive wetland resources of Bangladesh. The basin supports a large variety of wetland bio-diversity and works as natural reservoir as it plays a key role in basin water resources by regulating water flows of the Meghna river system. Also, the haors are noted sanctuaries of both permanent and migratory birds. With the recession of floodwater, a large variety of small fishes, oysters, water snails and bivalves, and pasture spread over the surface attracting a large number of migratory birds. These birds use the haor as temporary resting and roosting ground before moving elsewhere. The swamp forests, which were once dominant with the flood tolerant tree species like hijal (Barringtonia acutangula) and Koroch (Pongamia pinnata), have been reduced to a few small patches. The haors are also important fishing grounds of the country. In the past century or so, when the population pressure was less, most of the rim-lands of the haors remained as cultivable wasteland and was used for extensive grazing in the dry season. As population increased, boro cultivation expanded onto these marginal lands leading to a large area being drained. Thus, the very existences of these wetlands are now threatened.

Shah Jalal of Sylhet....a factfile
«on: 08/05/04 at 06:10:54 »

Shah Jalal is one of the most revered legendary Islamic heroes of Bangladesh and one of the key founding fathers of Islam in the country. He was a great saint and a great warrior. He, along with his disciples, had unique contribution in liberating the people of Sylhet region both from the racial rule of the Hindu kings and the prejudices of paganism.

His full full name is Sheikh-ul Mashaek Mokhdum Sheikh Shah Jalal Mozorrodh Bin Muhammed. Although historians are divided on the issue of his birth-palce, the majority of them thinks that he was born in 1271 in Konya, Turky.

Shah Jalal's father was contemporary to Mawlana Jalal Uddin Rumi. Rumi's mazaar is also situated in Shah Jalal's birthplace, Konya in Turky. His ancestors came from Yemen, hence he is also called the Mozorrodh-e-Yemeni. Shah Jalal was raised by his maternal uncle, Syed Ahemd Kabir, in Mecca. He became a Hafiz (those who know the Holy Koran by heart) and also became proficient in Islamic theology. Legend has it that one day his uncle gave him a handful of earth and ask him to go to Hindustan with the instruction that whichever place in Hindustan matches this earth completely in smell and color, he should settle down for preaching and establishing Islam.

Shah Jalal journeyed eastward and reached Hindustan (modern India) in c. 1300. In Ajmir, he met the great Sufi mystic (Dervish/Pir), Kwaja Gharibnawaz Moinuddin Hasan Chisty. He also met with Nizam Uddin Awlia (1236-1325), a prominent Dervish, in Delhi. Nizam Uddin requested him to go to Sylhet to rescue Sheikh Burhan Uddin. The Sheikh was only a handful of Muslims living in the kingdom of a Hindu King, Gaur Gavindha. He secretly slaughtered a cow to perform his son's Akika (christening of child in Muslim culture). It is said that a crow carried a piece of meat and dropped it in the king's yard. The enraged king ordered killing of the Sheikh's son and the Sheikh himself was imprisoned. Sheikh Burhan Uddin's mazaar (shrine) is located in the banks of river Surma in Sylhet town.

Shah Jalal reached Sylhet with 360 Awlias (disciples). Some of the awlias originally followed him from Delhi, and some joined on the way to Sylhet. Knowing that Shah Jalal was advancing toward Sylhet, the king removed all ferry boats from the river Surma. Legend has it that Shah Jalal crossed the river Surma by sitting in a Zainamaaz (prayer rug). Muslim force was defeated by the king twice previously. However, this time the king ran away after being deafeated by the force led by Shah Jalal after a fierce battle. Shah Jalal also found a match of the earth his uncle once gave him. He settled down in a placed called Drag Mahallah, near Choukidhiki. He preached Islam from there. He and his disciples also travelled as far as Mymensingh and Dhaka.

In his book "Afdalul Hawaade", poet Hazrat Amir Khosru gave exact dates of Shah Jalal's travel to Sylhet. Khosru was a Moghul court poet, and considered the founder of Urdu language. Persian traveller, Ibn Batuta, also came to Sylhet to meet Shah Jalal.

The exact date of his death is unknown. According to Ibn Batuta, it was 1347. He died at Sylhet, Bangladesh.

Shah Jalal's nephew, Hazrat Shah Paran, lived out of town, in Major Tila area. Legend says that he was of very high temper and would curse people when they are unruly and the curse would come true. To save people from his wrath, Shah Jalal ordered him to settle down just the outskirt of the town.

Dear All,
Kaulka ekta “Maths trick” pathaicilam Asiti babu-re, pula-maiya-re shikaibar lagia. Tain ita paria khub vala paichuin. Eirakam gnani guni manusher pith chaprani paiya ami sahas paichi. Okhon sabaire sunailai.

http://www.speed-math.com/
Based on Professor Jakow Trachtenberg's system of simple methods to perform high speed mathematics.

[b]How to multiply 85 X 85 or 58 X 58[/b]

This is a trick to find square of any two digits number with digit “5” in it .

[color=Blue]Case 1 [/color]
When the digit “5” is in last place like 85, 95, 45, 15 etc.

Example 85X85

The answer will be four digits figure say A B C D
The digit C D will be always 2 5
To find digit A B multiply the first digit ( here it is 8 ) with (8+1) i.e. 8*(8+1) = 72
So the answer is 85 x 85 = 7225.

Example 15 X 15

To find A B, here it is 1*(1+1)= 2 ( consider it as 02, here “A” is zero which is meaningless )
Since C D is always 25, the answer is 15 x 15 = 225

Example 195 X 195

To find A B : here it is 19*(19+1)= 19*20=380
Since C D is always 25 the answer is 195 x 195 = 38025

[color=Blue]Case 2)[/color] :
When the digit “5” is in the first place ie. 51, 54, 58. 59 etc.

Example 51 x 51

Here the last two digits C D will be square of the last digit ( here it is 1 ) so, 1 to the power 2 = 1.
Since the answer has to be two digits number, change 1 to 01.([color=red] caution [/color]: though “C” is Zero, it cannot be ignored )
First two digits A B will be (25+last digit) = (25 + 1) = 26
So the answer is 51x51 = 2601

Example 59 x 59

Here C D is square of 9 i.e. 9** 2 = 81.
And A B is (25+ last digit) =(25+9)=34
So the answer is 59x59 = 3481

Shankar da nice one..!!!

kintu jadi amra basic jinish ta follow kari..taile other than 5 also we can calculate in few seconds...

(a+b) whole square or (a-b)whole square.

Suppose number is 58..
so make it (60-2)whole square =3600-240+4=3364
to make this calculation faster u can first subtract 240 from 3600 and then add 4.

Suppose the number is 53..
(50+3)whole square = 2500+300+9 =2809

Re: Knowledge Sharing

Dear Taar Cheera,
Thank you for your good suggestion.
In my opinion, your method is more suitable for squaring numbers like 32, 68, 87, 79 where digit 5 is not there. With digit 5, it becomes very simple because last 2 digits are always 25 and first two digits are X*(X+1). Or 25+X and X*X. However if you are more comfortable with your method, please don’t change it for my sake! Anyway, thanks again for your response, and please tell us more such tricks.

TC je method ta suggest korchhe, ita application of algebraic formula, je guli usually in CBSE course e class VI e pao a jai as exercise. Kintu, je class V o pore, he algebraic method [ie, dissecting the number into two favourable parts etc] bujhto parto nai. Moreover, it also involves squaring the component numbers. Itar lagiya thumb rule er khub dorkar.

5 containing number er sqaure korar thumb rule ta khub effective, karon tar lagiya user khali place value guli use korer.

Ei dhoroner thumb rule method onyo number er lagiya achheni? Infact, some one suggested, assam er "kaithali anka" [Kayastha arithmetic] ar Shubhankar er "Airjya" can give many many shortcuts. Shakuntala Devi'r as well as many "child prodigy" r working secret hoilo ei shob thumb rule.

This whole number tricks hold good for other multiplication also.
Suppose 48*13.

So, (50-2)*13=650-26=624.

But Asit Da (with respect) do you really feel that we should teach this tricks to our kid? I feel we should give enough space to our kid to show their creativity.

These tricks really work fine in case of competitive exam like CAT and others where time is a matter and at the same time calculator is not allowed.

TC...your point is absolutely correct. These tricks are most useful in competitive exams, and not much useful for school students. The students cannot apply these in their school work or exams because these are not prescribed in their syllabus.

However the tricks have other uses. These tricks can surely boost the morale of the "Mathematically Weak" students. These would provide the psychological advantages.

In Delhi, there are a number of small home run Mental Maths courses which give such tricks to kids at a pretty high cost. It has been reported that many kids who were afraid of maths, have started showing interest in the subject.

Some more tricks..

I. Multiply any two numbers within 20
suppose the numbers are 19*16

Take the larger one ie 19 and then add first digit of the second number ie 6

So, number is 25 now put a '0' at the right most side(ie multiply with 10)
so, number is 250.
Now multiply 9 and 6 ie 54 and add this to 250. it ll be 304..

II. Multiply any two digit number by 11

54 *11
Add the two digit 5+4=9 ,put this 9 in between 54 ie 594

The only thing tricky to remember is that if the result of the addition is greater than 9, you only put the "ones" digit in the hole and carry the "tens" digit from the addition. For example 11 x 57 ... 5__7 ... 5+7=12 ... put the 2 in the hole and add the 1 from the 12 to the 5 in to get 6 for a result of 627 ... 11 x 57 = 627

III. Multiply any number by 5

Divide thh number by 2 and multiply it by 10

Number is 79, divide by 2 ie 39.5 , now multiply by 10 ie 395

A.Squaring numbers made up of threes

33333*33333

StepI. Total number of 3 = 5
Now first put four 1's (one fewer than
digits in number) . so 1111
Step II. next digit is 0. so 11110
StepIII. four 8's (same number as 1's). so 111108888
StepIV. now at the end put one 9. So, answer is 1111088889

B.Squaring numbers made up of six

66666666*66666666
StepI. Total number of 6 = 8
StpeII. Put 4's (one less than digits in number) = 4444444
StepIII. Next put 3 =44444443
StepIV. 5's (same number as 4's) =444444435555555
Step V. Put one 6 at the end = 4444444355555556

C.Squaring numbers made up of nine

999*999=998001..

Dear Taar Cheera,

Thanks , Wonderful posts, in proper words Hulusthul jomse!!
I have noted down all of them in my diary.
With your permission, I would like to add some more Trachtenberg's fun in your basket.

Case I Your method can be extrapolated to find the square of any number ( Dr. AKS this answers your question )

Square of 46

The rule is 46 X 46 ={ ( the number + last digit )* first
digit } *10 + { square of last digit }
= { ( 46 + 6 ) * 4 }*10 + { 6**2 }
= { 52 * 4 }*10 + { 36 }
= { 2080 } + { 36 }
So answer is 46 X 46 = 2116

This is applicable for higher numbers also but doing it mentally is difficult.

Square of 379

379 ** 2 = {(379+ 9) * 37 }* 10 } +{9**2}
= { 388* 37 *10 } + { 81 }
= { 143560 } + { 81 }
= 143641

Case II. Your method can be applied for any digit number.
Multiplication by 11 for any number is summing
the adjacent numbers

4267 *11
the last number is 7 so write 7
next number is 7+6 =13 so write 37 and carry over 1
next number is 1+6+2 =9 so write 937 and no carry over
next number is 0+2+4 =6 so write 6937 and no carry over
next number is 0+4 =4 so write 46937 this is the answer.

At the end I fully agree with you and Dr. AKS that these tricks are not to confuse school children but to motivate them to see maths as a fun subject. So Taar Cheera please post more fun for all of us.
