Don’t you feel little COOL after sweat, though smelled badly?

Your body perspires, or sweats, to COOL itself off. It is also another way for your body to get rid of wastes. Each day, your body makes heat as it burns fuel or food, for energy. When this heat causes the temperature of your blood to rise, the cooling center of your brain goes to work.

First, your body slows down the burning of fuel. Then the blood vessels in your skin widen. This allows more blood to flow. More it flows, more the heat that is given off through the skin. At the same time, the sweat glands that are in your skin make more sweat. Sweat is made mostly of water and a bit of salt and waste. When sweat hits the skin, it begins to evaporate or change into a mist in the air. This evaporation process also helps to cool your body.

Who is Alfred Nobel?


                Most of us know that it’s an international awards bestowed in recognition of fields x y z  and what is the procedure to nominate and to pick one from each field of Scientific advances and Cultural. But very few know the reason behind it, after reading about the Alfred Nobel who sacrificed his enormous wealth to give it as a series of price with such a protocol of no boundaries of religion, nation, community or particular corner of the globe. I felt Alfred is kind hearted and really a great creature to mankind. One interesting fact is that, he was not alive to issue single prize composed of his only fortune.
                Alfred Nobel born in Stockholm, Sweden in 1833. At his 18th age, he went to US to learn Chemistry and later he involved in business with his brother Ludving Nobel. As years passed, unfortunately he had to return to Sweden after bankruptcy of their family biz. Then he dedicated himself to the study of explosives and invented the dynamite and held some 355 different patents, dynamite being the most famous.
                Alfred was a scientist, inventor, entrepreneur, author and pacifist. Though Alfred remained unmarried, his biographies note that he had at least three lovers. Alexandra first love, rejected his proposal. 2nd Bertha, his secretary, left him to marry previous lover. It’s believed that, she was the major influence in his decision to include a peace prize in his will. Bertha was awarded the 1905 Nobel Peace prize for her sincere peace activities. 3rd and longest-lasting with flower girl named Sofie Hess for around 18 years with many letters exchanged.  In 1985, Alfred wrote his last will leaving his wealth to establish Nobel Prize and died in Dec 1896.
Nobel Prize would be awarded on 10th of every December, anniversary of Alfred Nobel’s death. Peace prize is awarded in Osla, Norway (by Norwegion Nobel committee) and others in Stockholm, Sweden (Royal Swedish academy of Science). Each Laureate receives a gold medal (average of 175 grams), a diploma and a sum of money approximately 6crore rupees considering foundation’s income on previous year.
A maximum of three persons & two different works can be selected per award. Except peace prize, which can be awarded to institution, others can only be given to individuals. It’s not compulsory to issue award in all fields every year and if not awarded in any field, the money is split among the rest.
There are few specially distinguished laureates, four have received prizes twice. (Maria Curie one each for Physics & Chemistry, Linus Pauling for Chemistry & Peace, Johhn Bardan twice in Physics & Frederick Smger, twice in Chemistry) and Curie family is the great one, who bagged 5 prizes (Maria Curie-2, her husband, Pierse -1, First daughter ,Irene Joliot-1 & second daughter, Henry Labousse). 

          Another very interesting fact is that, Gandhi didn’t award for his peace policy. But four people those who adopted his policy namely Nelson Mandela, Fredrik Willem, Aung San & Dhalailama awarded Nobel Peace prize.

Why does a laptop lid feel cold to touch?

STRESS STRESS STRESS uhh .. fire running through hairs, hears & forehead totally my head was like red burning firewood and was about to smash my laptop lid by my left hand, WOW!! Something strange, felt somewhat COOL. That takes my mind off from workspace. Felt why I shouldn’t make this lid as pillow for a moment. What was that really….? Looking at Canara bank envelop lying on my desk, remembered a scenario which happened when we friends travelling from Bangalore to Mandya in a train. There in train, looking at Canara bank Add  posted in compartments wall “You have dream, will fulfill it”, I told my friend similarly Google should have something like “Have a query, I have answer”. Then I got the below…..,

Metals feel cold when you touch them because they are good conductors of heat. They conduct heat away from the skin on your hand and the temperature receptors in your skin register this as a drop in temperature, so the surface of the metal appears to be cool.

Why few people prefer to sit on floor and eat?

      Person having the meal sitting on the floor has to bend significantly to consume food and hence stomach gets pressed. After consuming food, the person takes his chest back to position to sit straight. This cycle helps the movement of the abdominal muscles. The constant movement of abdominal muscles causes the secretion of digestive juices which in turn assists the consumed food become softer and facilitates the process of digestion.
   
   In other case,

person having his meal sitting on the dinning table has to bend his neck slightly, as plate comes upto chest level.

Why ceiling fan rotates in anticlockwise direction?


     The Table fan's motor is fixed to the stand and its rotor rotates with the fan blades, whereas in case of a Ceiling Fan the Motor rotates and its inner rotor is fixed to the ceiling clamp. If that has to run in clock wise direction then it pushes the Fan in anticlockwise direction. It means both the ceiling fan and the table fan both works in the same direction but since its design varies it appears to rotate in opposite direction.

     Also very few countries design ceiling fans that could rotate either way depending on whether winter or summer. Heat rises...so depending on the season you'd pick the direction. One way would remove the hot air from the ceiling and circulate it into the room (winter) while the other direction would recirculate the hot air within the room making it feel cooler (summer). It's as simple as to replicate natural air density phenomenon "It allows down-flow during the warm season and up flow during the winter".

Standards are made to ordinary but not for extraordinary, because they did it.
More than standard style(assuming ceiling fan preferred for comparatively bigger room space).


 This uniquely curved blades that push air down at an angle rather than straight down like a standard fan.

Q:Can I use a ceiling fan outside?

Why women shirts would have button on left side?


Mens’ buttons are on the right side because men have always tended to dress themselves.
It doesn't mean women do not!!
But years ago (say, during the Victorian Era), the women that could afford fancy clothing with a bunch of buttons would rely on maids to help dress them. So, if a servant is going to routinely buttoning up a shirt/dress for someone else, they prefer to have the buttons on their right side (which would be the left side of the garment).
Wasn't she thought that, she could hire left handed maid...? instead of going against...
Anyway thanks to our beloved kings, though it was difficult for their wives(maids) while buttoning.
