Why did Ashwattama killed upapandavas ??

 On the last day of Kurukshetra war, Kouravas were defeated.


Ashwattama had gone to the meet Duryodhana who was injured and was hiding in the lake. 


Ashwattama was very disturbed after meeting Duryodhana and vowed to kill Pandavas. 


But in the darkness of night, he killed upapandavas who were the children of Pandavas.


But the death of upapandavas were predecided. 


We know King Satya Harischandra who was famous for his truthfulness.


As Sage Vishwamitra was testing his truthfulness,  Harischandra gave up his kingdom and left with his wife and son.


But the 5 deities who were the guardian of kingdom, were unhappy with this and questioned the Sage. 


Vishwamitra was enraged by this and cursed the deities to born as mortals. 


But when deities pleaded for forgiveness, Vishwamitra said deities would be released of the curse before forming any attachments that would reduce their status and sanctity.


These 5 deities were the upapandavas.

I felt pity about him.


I asked my sister in law  why Aniruddha ?  He is still a baby !!!


My sister in law replied He is the one who will be asking for water to drink whenever or wherever I go.


That's why he must carry the water bottle  !!!


One more incident of child labour !!!

How Venus lose its water?

 We all know that planet Venus is the hottest planet in the solar system.


It is much hotter than Mercury which is closest to Sun. 


Venus lies in narrow virtual ring where planets can hold water in liquid state.


Billions of years ago, Venus used to have as much water as Earth is having now. 


Due to the proximity to the Sun, the sunlight is believed to have broken down the water in its atmosphere to hydrogen and oxygen.


Greater concentration of hydrogen in its atmosphere, rapidly heated up the planet.


That's how Venus is stripped out of its water. 

Bheja fry question

Quasl moon

 What is quasi moon ?


A quasi moon is a term used to describe an asteroid or space rock

 that orbits the sun in similar time frame as that of mother planet but

 is slightly influenced by mother planet 's gravitational force.




It appears to accompany the mother planet during the journey around

 the sun but is not considered a natural satellite.





As quasi moon share a weak gravitational link with their planet, they

 tend to escape this link and hurtle out of the orbit eventually.

Koun Banega Karodpati question

 I came across this question on Koun Banega Karodpati program recently.


Question 


Whose square is bigger ??

 3  ,   - 2    ,    1   ,    - 5



Answer 


I always get confused when they mix negative numbers with positive numbers .... 


In positive numbers,  value of number increases as number goes on increasing.... 


Like   6 , 16, 26, 36........


But it is not the same with negative numbers.


Value of the number decreases as the number increases. 


-60       is less than      - 10.

Whereas    60    is greater than   10.


Now let's come to the question. 

Square of which number is greater?


Some positive and negative numbers are given. 


Square means we are multiplying the number with itself. 


Positive number square will be always positive. 


But what about negative number  ???


Surprisingly even square of negative number is a positive number    !!!


Because   -    *     -     is   +

But   +  *  -    is   -

-    *     +   is   -


So in the above question,  square of  - 5 which is  +25  is bigger compared to the square of other numbers.

Which is first ? Egg or chicken....

 The above question was unanswered till now.


But now a group of English scientists have come with several evidences to prove  Chicken has come first  !!! 



Their theory is - - - 



1.  A protein called ovoclaudin is found in egg shell. 



2.  According to the scientists, without this protein egg shell can not be formed. 



3.  Interestingly, this protein can be found only in the uterus of chicken. 



4.  Eggshell plays crucial role in formation of egg. 



5.  From these findings., now we can conclude that 



               CHICKEN CAME FIRST, NOT EGG   !!!! 


But question still remains, 

                       From where does the chicken come   ??!! 

Why school buses are painted yellow ???

 When I asked this question to my father, he said that is the government order   !!!!



Well, it is true........ 



Government has ordered the school buseo to be painted yellow.  Not only in our country,  even in USA and Canada also school vans are painted yellow.  It is because of child safety.




Yellow colour attracts attention quickly and noticed quickly in peripheral vision, faster than any other colour. 




By using the yellow colour to paint the school bus, the school bus can be easily spotted in rainy and misty weather.

Secret behind T20 cricket world cup win of India

 We all know that 2024 T20 World Cup was won by India defeating South Africa.


In Great Indian Kapil show, members of the winning T20 cricket team had come as guests.


Surya, Shivam Dube, Axar Patel, Arshdeep Singh and captain Rohit Sharma were the guests. 


Speaking on the show, Rohit Sharma recalled the moment when South Africa were in absolute control of the chase with 30 runs required off the final 30 balls.


Klassen and Miller were there on the crease. 


That time Rohit Sharma noticed that Rishabh Pant was on the ground with team physio attending him.


Pant' s injury ploy caused a short delay in the match.


This was key in breaking momentum of South Africa. 


As soon as Klassen got out, pressure started to build up on South Africa.


At that time, Rohit Sharma gave his teammates freedom to sledge the South African batters    !!!!


This helped South African batters to get distracted. 


Rohit Sharma and his team were willing to take the risk of getting fined at the cost of scripting a title win. 

Kids are always kids !!!!

 I asked my nephew Aniruddha this question,


If Akash 's father is having 2 sons and name of one of them is Prakash,  what is the name of other son ???



Aniruddha was angry at everyone for unknown reason and I asked him this question !!!



Aniruddha hit me back, 

How do I know ??!!

It is  father's decision to name his children   !!!

Devils bath of New Zealand

 Devil's bath is an electric green sulphur lake in New Zealand.


It is also a neon green pool of stragnant stink water.


It is a boiling body of water, as the result of intense geological activities. 



The colour of the lake changes according to the inclination of Sun's rays and the amount of minerals present in water. 


The bright green water gets its colour from deposits of sulphur that rise to the surface and floats at the top.


The water changes its colour such as blue and red signify various volcanic elements.


The fumes created by sulphur deposits, inundated the entire area by a stinky smell. 


Dispite the name and almost frightening display of geothermal chemistry, it has become the tourist attraction.


It is not allowed to swim in the pond as it is highly acidic.

Kolluru Mookambika story

 From today, Navratri is started.


In this festive season, we worship Goddess Durga.. 


We worship other goddesses too. 


We know about Adi Shankaracharya. 


When he was performing penance , it occurred to him that Goddess Sharada is living in Kashmir.


He wanted the Goddess to come to South India. 


Likewise, Adi Shankaracharya requested the Goddess. 


How can a mother say  ' no ' to her child ???


Goddess agreed but put one condition. 


The condition is that  Shankaracharya must walk in the front.  Goddess will follow him till he stops and turns back.


Shankaracharya agreed. 


Shankaracharya started his journey towards South India and Goddess was following him. 


Shankaracharya could hear the sound of anklet of Goddess assuring him that Goddess is following him. 



This continued for many days. 


But  suddenly one day, the sound of anklet got stopped. 


Shankaracharya didn't hear the sound and he was worried. 


Finally Shankaracharya thought of breaking his promise. 


Shankaracharya stopped and turned back to watch whether the Goddess is still following. 


To Shankaracharya 's surprise, Goddess was following him without making any sound !!


Now the promise is broken and Goddess said that she will stay in that place itself. 


That place is     Kolluru. 

Most tea drinking countries

 I drink neither tea nor coffee.


But in my house and in my family, all prefer coffee more than tea. 


We South Indians prefer coffee than tea. 


But in Northern India,  people prefer tea than coffee. 


This difference in the minds of Indians, made India to take little lower position in the list of countries of tea drinkers. 


The list is as follows with the percentage of people drinking tea. 


1.  Turkey  ----  90% of people drink tea.


2.  Pakistan and Kenya  —-  83%

Basic things astronauts can't do in space

 Life in space is very difficult compared to life on earth.


These are the basic things that astronauts can't do in space.


1.  No Walking 

                  Astronauts can't walk in the space because of lack of gravity.  They float. They move in space by pushing walls.



2.  No crying 

                  Astronauts must not cry in space as their tears get stuck to their eyes.



3.  No shower

                Astronauts can't take shower as water don't flow in space due to lack of gravity.




4.  No cooking 

                 As fire need oxygen which is limited in space, astronauts rely on pre packaged food..




5.  Can't lie down

                Because of loss of gravity, astronauts secure themselves in sleeping bags attached to the wall. 

Koun Banega Karodpati question of 1 crore

 This question was for Rs 1 crore asked on Koun Banega Karodpati program recently.


Which country 's largest  city is not its capital but a port city ???


1.  Somalia 


2.  Tanzania 


3.  Yemen 


4.  Brunei 



Answer 


By reading the question,  I wondered is each and every country's largest city, its capital ???!!!


May not be. 


The question seems confusing. Largest city in what sense??


If we take our own country, India


New Delhi is our capital.  It is a largest city in terms of area. 


But Mumbai is the largest city in terms of population. 


So, question is not clear. 


But if we look at the options, we can nearly come to some conclusion. 


I know about Brunei as our Prime Minister recently visited the country. 


It may not be the answer. 


The remaining  2 countries, Somalia and Yemen, are notorious for their political instability.


I don't know much about Tanzania. I know only one fact that it is in African continent.


Correct answer is        Tanzania

Why can't we survive by drinking salt water ??

 Over 70% of earth's surface is covered with water.


Most of this water is undrinkable salt water.


Though our body needs both salt and water to function, we can not drink salt water  !!!!


It is because our body needs little amount of salt. Ocean salt water has more amount of salt in it. 


When we take in too much salt, our kidneys must get rid of this excess salt through our urine.


Ocean salt water is considered hypertonic fluid means ocean salt water contains more salt than human blood.


Drinking salt water results in our body getting rid of the excess salt by urinating more water than we took in.


Instead of quenching our thirst, our body suffers a net loss of water.


This will result in dehydration and increased thirst leading to death.
