Rice Cooker Disease?

Before electric rice cooker was introduced in our kitchen cooking rice was an art. Not many could boast about knowing the art. Even pro mothers could land up with bad pots once in a while. I remember how my mother would be on her toes once the rinsed rice was poured into the boiling water. She would keep stirring it and from time to time she would spoon out few grains and feel them between her fingers.

Once she got the right feel, which was when the grain was soften all around except a tiny bit in the centre, she would remove the pot from the oven and drain out the thick rice soup that was half the content of the pot. Then the pot was put back on the oven with low heat. I always wondered how my mother knew how much longer to wait after that because I mostly landed up with either uncooked or burnt rice.

That short story on the art of cooking rice can be a history lesson for young Bhutanese born after 90s. Because after electric rice cooker came cooking rice literally became a child's play. All you have to do is rinse the rice, along with some water pour it in the cooker. Put your index finger to see if the water level is at the first line of your finger above the level of the rice. Close the cooker. Pull the light down to 'cook' and go to sleep till mother comes home to prepare the curry. Of course some can't even do that much.

Besides the art and history of cooking rice there also seems to be solid science involved in it, which is gradually surfacing in the form of a disease. The deadly disease is called diabetes. It's sugary but not at all a sweet disease it mess with. We understand that it is to do with excessive sugar in our blood that our pancreas can't handle. But how did this happen?

Bhutan didn't have this disease before, perhaps there were some cases that we were ignorant about but now it has become so common. Well, the answer could be in the rice cooker. A research in Singapore ( Story published in Strait Times) has shown that a plate of rice is as bad as two cans of sweetened soft drink. Ask yourself how many plates you eat in a day.

We Bhutanese always ate rice, so before you ask me why I blamed rice cooker here let me tell you that before rice cooker we boiled rice till it gave away whatever it contained and drained out the soup. Remember the history lesson. So the rice we were eating didn't contain all the sugar it came with but now we are taking in every bit of sugar it contains because there is no draining out of soup.

We started using rice cookers in 90s and in the last two decades we must have forgotten how to cook rice without rice cooker but we have produced enough diabetic parents to relearn the art of cooking rice the old way.

The Buffalo Horn in Daga Dzong

In my last post I wrote about the mythical treasure of Daga Dzong but I have not discussed about where it came from. I could only write about having seen it for real. It was a 7.2 feet long buffalo horn, which is by far the largest in the world (at least as far as I know).
Illustration of the Horn in comparison to my height

THE LEGEND

The Legend has it that one day in 17th century, people living in Daga Dzong heard an unusual bellow of a buffalo from the deep jungle across the valley. The Lam (ID not known) sent his subjects to check on the animal but upon reaching the site all they found was a pair of gigantic horns.

They pair of horns were kept in Daga Dzong for centuries and over the years, it was said that the horns were carelessly thrown all over the place until one day one horn flew away. It was then that the single horn left behind was received back in the Goenkhang of the Daga Dzong and treated as one very important treasure.

The other horn which flew away is believed to be in Talo Monastery in Punakha (Need to confirm). It's pity that I didn't know about it when I was close to Talo. I visited Talo twice and if it was true it can't be missed, literally.

ASSUMPTION

After having seen the horn itself there is nothing so unbelievable about anything but because horns don't have wings I am a bit suspicious about the flying horn myth. I rather prefer to believe that the horn was brought to Punakha as a gift, because Daga Penlop was known in history has someone who brought the best gifts to Punakha Dzong during those day.
The Three Parallel Staircase, Punakha Dzong
It's said that the three parallel staircase in Punakha Dzong were for Trongsa Penlop, Paro Penlop and Daga Penlop, where Daga Penlop was given the privilege to climb the central stair because of the kind of gifts he presented. Perhaps he must have brought it along with so many ivories he presented to Zhabdrung those days.

But how it reached Talo could be another story or may be it really flew, or perhaps it's not even in Talo. (There is more to learn about this fascinating legend)

SCIENCE OF THE HORN

After seeing the horn, I have looked all over the internet to see if there is any 7 feet long buffalo horn in the world but I found none. In fact, no species of buffalo has horns that looked close to the one in Daga Dzong. Of course none matched its size too. So is it really buffalo horn?


Bongo with Large Horns
As I pursue my fascination for largest horns I stumbled upon Bongo, the largest and heaviest antelope found in the Lowland Rain Forest of West Africa and the Congo Basin to the Central African Republic and Southern Sudan. This animal has similar horns that grow very long. But again how could a pair of horns from Africa land up in Dagana? and More over the world record holding Bongo horn is just 3 feet long, no where close to the 7 feet long mythical horn in Daga Dzong.

Therefore the mystery remains and it's best left that way. 

2015 is observed as Visit Bhutan Year and it's time we Bhutanese visit our own country and enjoy its unmatched cultural heritage and endless mysteries. I am giving you 7 feet long reason to visit Daga Dzong this year. World dreams to visit our country, we are already here!

Young Bhutanese Scientists

The 2014 Cluster II Science & Technology Exhibition in Bajothang is the grandest I have ever seen. Children from twelve higher secondary schools have broken many barriers though there is no denying that we are still caught in the box by international standards.

The chief guest, Madam Secretary took special interest in every exhibit and often remarked in amazement: "You should patent it". Each school presented three exhibits each and the result was calculated from the average of three

The winner was Ugyen Academy took home a cash prize of Nu.25,000. They presented a Multipurpose Machine- a washing machine and spinner, grinder, rice mill and water pump- run by paddle connected to series of gears. The carpentry and welding works are done so beautifully that it ought to win.
1. Multipurpose Machine, Ugyen Academy
The team also presented a concept of traffic signal that is a result of complex algorithm of circuits.
1. Traffic Light Concept, Ugyen Academy
And their third exhibit was a solar food dryer that they claim can also be used as cooker. They have also brought along a TV disc that can also heat water. But since only three exhibits were allowed they must have presented either of the two, anyway they were declared the winner! Congratulations.
1. TV Disc and Food Dryer, Ugyen Academy
The first runners up was explosive literally, it's my school Bajothang. They have made an anti fire ball, which when thrown in fire will explode and extinguish the fire. The demonstration impressed many people but the idea to me seemed imitated.
2. Anti Fire Ball, Bajothang HSS
Next was a Mop on the Wheel. This can be driven across the floor and the wheel will help turn the sponge that will clean the floor, the handle has a pair of switches to spray water and soap on the floor.

2. Mechanical Mop, Bajothang HSS
 Our third exhibit was a traditional grinder (rangtha) driven by gears connected to paddle.

2. Grinder, Bajothang HSS
Second runners up was Gelephu Higher Secondary School who were more into chemistry, they demonstrated the procedure to extract vinegar from bamboo.
3. Bamboo Vinegar Extractor
and also show us how to make bio-plastic from potato. The plastic can be fried into chips after use or cook as curry lol.
3. Bio Plastic
And they impressed us with their miniture robotic bull. The bull is run by series of motors and can be maneavured into any direction including reverse.  They took home Nu.15,000.
3. Robotic Bull, Gelephu HSS
I will share about the rest of the exhibits after I finish compiling the official report. Some of them are even better than the ones I have shown here, but they couldn't win because the result is based on the average of all three exhibits.

How Are Scientists Made?

Does it take a scientist to invent a scientist? Seemingly yes because we never had a Bhutanese Scientist and therefore we don't have another. There is no inspirational figure to look up to for the students who are pursuing science. The highest dream they can dare is a mere MBBS. I don't know if the science we teach in school is only capable of making children dream as far as engineering college or medical college. Invention cannot be taught of course but how is it inspired?

School Science Exhibition is perhaps one obvious optional answer. By that I don't mean those namesake events where children do imitations of steam boat, waste chemicals from science lab to replicate volcanic eruption (for the thousandth time) or make a rocket with plastic bottle and football pump that will only fly two meters high.

School science exhibitions have reached new heights now. Children now make chopping and grinding machines with renewable energy, solar mobile phone charger, bicycle mop, and prototype of very futuristic machines. I am very excited to see what other 11 schools will come up with at the 2014 Science & Technology Exhibition in my school on May 10, 2014. These schools are coming from eight different dzongkhags.
The Logo images are not original, integration is :)
Each school will showcase three exhibits, which were the best from their own school exhibitions. The winning school takes home Nu.25,000 and load of inspiration. Sadly it stops there. Because unlike in other countries no company takes part to see if there are some inventions they could invest in. I hope this happens down the line.

We could go that far to bring in companies but at least we have taken the first step toward making the Science Exhibition very scientific. The judges we are bringing in are not only science lovers but some of them have inspiring inventions in their names. Two of the judges will present their inventions and brave attempts to the expected 72 budding student scientists on May 9, 2014. 

The venue my school has set up will win every heart that comes here, every little soul is hard at work these few days to make the place so welcoming that no one would want to go back. The school intents to make the whole experience the most memorable and inspiring.

On the Exhibition day I will be photographing and compiling reports on every exhibit and I intent to share them here with you all. But if you are around or if you love science enough to come all the way to Bajothang from wherever you are, you are invited.
