Origin of word Algebra

Algebra is the part of mathematics . It deals with variants x,y, z sometimes a, b, c etc. The ultimate goal is to find the value of the variant.
Algebra , the word seems like having Arabic origin. It is the Latin form of the Arabic word Al - Jabr. 
The word is derived from  title of a Arabic book.
In Arabic, Al means the. Jabr means equation.
Hence, we can say that Algebra means balancing the equation.

Why does a fish die after taking out of water?

                              Why does a fish die after taking out of water?

This question may seem silly. Everyone knows that fish need water to survive. Fish uses a pair of gills , which it uses to breathe under water.
The gills extract the oxygen from water molecule . Gills maintains regulation between oxygen and hydrogen proportion of water molecule.
When a fish is taken out of water and exposed only to air , not the oxygen and hydrogen contained water then its gills can not control the oxygen taken. Its delicate balance between hydrogen and oxygen is lost. It dies because of inhalation of overdose of oxygen.

What would happen if there is no dust?

                 What would happen if there is no dust?

It is painful thing to see a just swept  floor is again covered with dust. I always thought that if there is no dust in the world, our just cleaned floors will remain clean forever ! No need to do cleaning work daily and is also a saving of precious time.
But we would repent afterwards , if there is no dust. Because , without dust there would be less rainfall . Rain is formed when the water molecules in the air collect around dust particles. When collected water is heavy enough, water droplet falls to Earth in form of rain.
I always wondered why Bangalore is having much rain eventhough there are less trees. In our area, trees are every where.
But in our place, we experiance rainfall only in rainy season . Bangalore is most polluted and dust particles are more there.
Even rainfall occurs there through out the year !

What is amnesia?

                                    What is amnesia?

We all are familiar with this term, not the word. I have used the word which is used scientifically but is better known as Memory Loss.
It is a self preservation mechanism when a person need to protect themselves , from severe emotional or physical trauma.
A person subconsciously blocks out the pain of trauma so deeply that he has no memory of them. Some times, he may lose his identity itself.
Recovery time varies from person to person. But in our movies, hero will get back his memory before the film ends !

Why is a wedding ring always worn on 3rd finger counting from index?

           Why is a wedding ring always worn on 3rd finger counting from index?

In matrimonial procedure , the groom and bride always wear their wedding rings on 3rd finger . This has become a rule.
Before medical science discovered how the circulatory system works , people believed that a vein of blood ran directly from the third finger of left hand to heart.
By wearing the ring on the 3rd finger of left hand, the couple symbolically declares their love for each other.

Story of Tulu saying

                             Story of Tulu saying

Ammer korida goodlla ijjer.

ಅಮ್ಮೆರ್ ಕೋರಿದ ಗೂಡ್ ಲಾ ಇಜ್ಜೆರ್ .


To explain this , there is a short story.
There was a man who had taken loans from many people. But he could not repay them. Hence he was hiding in the house.
For hiding, he has chosen the place where the hens are kept. Usually , no one will search in that place. He had a small child , his son ,in his house who was observing all of his work.
Sensing trouble , he called the child near and instructed him not to disclose the hiding area for anyone who asks for him.
Son agreed.
He hid in the den of hens. Lenders came looking for him. They spotted his son in the house. They asked the son where is his father?
At that time , son replied that father is not in the house , not even in den of hens !
It is upto reader's intelligence to find out whether the borrower was caught or not !

Where is the justice ?

Yesterday , I read in the newspaper that depression has been formed in Arabian Sea and moderate to heavy rainfall is expected in interior Karnataka.
I started calculating the distance between my house and Arabian Sea.
Arabian Sea is very close to my house. My question is instead of giving rain to our area , why are the clouds giving rain in other part?
We are the people who are tolerating humid climate which is because of Arabian Sea . But how can clouds go to other part of Karnataka to give rain ?
Here it is sunny. I am very disturbed by the injustice of clouds !

How do mirrors work ?

                              How do mirrors work ?

We see objects in a mirror. When hit by particles of light called photons , mirror reflects these photons back to us and some reach and enter our eyes.
The photons when hit a smooth surface, such as a mirror, will bounce off of the surface at the same angle at which they had hit the object.
When we stand infront of a mirror, the photons which reflect our image back to our eyes, are hitting the mirror at the same angle in which they are bouncing back.

Gunda is back. . .

I didn't meet Gunda for many days after seeing his miserable condition. I thought he is counting his last days .. .
Yesterday I was sitting in verandah watching pea-hens who came in group to eat mango fruits on nearby trees ; suddenly I saw Gunda coming in the direction of our house.
He must had spotted me , suddenly he changed his path and started walking near pea - hens scolding them for eating mangoes.
I smiled as I know Gunda is trying to impress me. But pea- hens didnt care for him. Seeing his effort going in vain , Gunda came near me with a face covered with shyness.
That time , my parents came outside and he said " hello " to both of them. He didnt come near me as my parents were present. He sat in the corner and started licking his hand !

ಚೊರ್ಪಟ್ ಮಳೆ

ನಿನ್ನೆ ಉಡುಪಿಯಲ್ಲಿ ದಿನವಿಡೀ ಚಿರಿ - ಪಿರಿ ( ಚೊರ್ಪಟ್  ) ಮಳೆ
ಕರಾವಳಿಯಲ್ಲಿ ಮಳೆಯ ಈ ರೂಪ  ಹೊಸದೇನಲ್ಲ . ಇಡೀ ಬೇಸಿಗೆಯ ಸುಡುವ ಬಿಸಿಲನ್ನು ಈ ರೀತಿಯ ಮಳೆಗಾಲದ ಮಳೆಯ ನಿರೀಕ್ಷೆಯಲ್ಲೇ ಕಳೆಯುವವರು ನಾವು . 
ಆದರೆ ನಿನ್ನೆಯ ಅಕಾಲಿಕ ಮಳೆ ಇದಕ್ಕೆ ಹೊರತಾದದ್ದು . ಬೇಸಿಗೆಯಲ್ಲಿ ಈ ರೀತಿಯ ಮಳೆ ನನಗೆ ಅಪರೂಪ . ಬೇಸಿಗೆಯಲ್ಲಿ ಇಲ್ಲಿ ಮಳೆ ಬರುವುದೇ ದೊಡ್ಡ ವಿಷಯ . 
ಅದರಲ್ಲೂ ಬೆಳಗ್ಗೆಯಿಂದ ಹಠ ಹಿಡಿದ ಮಗುವಿನಂತೆ ಕಾಡುವ ಮಳೆ ಮಳೆಗಾಲಕ್ಕೆ ಬಂದರೆ ಚೆನ್ನ . ಅದಕ್ಕೂ ಗೌರವ !
ಆದರೂ ಈ ಮಳೆಯಿಂದ ತಾಪಮಾನ ಕಡಿಮೆಯಾದದ್ದು ಸುಳ್ಳಲ್ಲ .

What is stray current?

Stray current refers to the flow of electricity via buildings , ground or the equipment due to electrical system imbalance or wiring flaws.
It also refers to the existence of electrical potential that can be found across the objects that should not be subjected to voltage.
Small voltages and small amount of stray current do exist within the power system. On the other hand , large amount of voltage could be a sign of a faulty electrical system.
Electrical currents that are not utilized , return to the source via the phase or neutral wires. If an electrical system is not  installed properly , the current can directly disperse to the ground through the equipment or building itself. 
In such cases, stray current can exist in small amounts and it would not be a problem. It can be fatal if it is present in dangerously high levels.
The same thing happens while a person gets electrocuted. Our body as it is largely made of water, acts as a conductor for electric current. During rainy season, if we get electrocuted by lighting which has enormous amount of electricity in it , it proves fatal to our lives.
I read news about persons death because of electrocution in newspaper.

M. E. R. S. ---- Middle East Respiratory Syndrome

With this , we can now conclude that it is the name of a disease. It is caused by a virus called Corona Virus. These viruses are called by this name since they have crown like projections on their surface.
These viruses commonly cause respiratory illness in mammals including humans.
This virus started making people ill since 2012. It was first identified in Saudi Arabia . Victim had died in the same year.
So far , cases of confirmed MERS infection are reported through out middle east.

Why do we use crushed stones in transformer area?

Near my house , a building under construction is complete and they have installed a transformer. Now they have covered the area below to transformer with crushed stones.
I have seen in many places  , the same phenomena.
Crushed stone is a highly resistive material and is used to protect the passing persons from step potential which may be very high and dangerous if there is an electrical fault.
The other reasons are to avoid water stagnation ,to prevent growth of plants under transformer.
The main reason for placing the stones is to protect the person from High Voltage ( HV ) while walking. We know that we can not walk fast over stones , our steps do become slow and with this our stepping potential becomes less which is very important for our safety, since stepping potential must not be more than a certain calculated value.

Bee Goddess - Bhramari Devi

                                    Bee Goddess - Bhramari Devi

According to Hindu mythology, once there lived a demon named Aruna. He wanted to establish his kingdom by driving out all the devas.
For this reason, he did hard meditation and got the boon that he will not be killed by any creature which has 2 legs or 4 legs. That means he can not be defeated by any human , deva , other demon or any other animal , having 4 legs.
This made him almost invincible. He invaded heaven. By seeing him, all the devas fled fearing for their life , leaving behind their wives and children in heaven.
Aruna in rage ordered his army to bring out all the women and children who are present in heaven. Army brought all of them infront of him.
Fearing for their life, wives of devas prayed to goddess Adi Parashakti. Adi Parashakti had known about boon that Aruna had got.
She had taken the form of bee , which has 6 legs. From that she is not contradicting the vows of boon. She had come with swarm of bees.
All of bees attacked the demon army and goddess herself stung the demon , Aruna to his death. From that time, she was called Bhramari Devi / Bhramarambika ( Bhramara means bee in Sanskrit ) . Thus , she saved the world from the clutches of demon.
