Baking soda while cooking veggies

 If we add a pinch of baking soda when cooking vegetables, they get cooked easily.

Baking soda softens vegetable cell walls through a chemical process called alkalization.

Plant cells are bound by pectin.  It acts like cement between cell walls.

 Mixing baking soda to the water in which vegetables are supposed to cook, baking soda raises the water pH, thus making it alkaline.

In alkaline environment, pectin bonds breaks down quickly. This further reduces the rigidity of tough and fibrous vegetables.

This allows the boiling water to penetrate into vegetable, significantly reducing cooking time.

Places where magnetic compass stop working....

 Magnetic compasses always point towards Earth's magnetic north.

But there are some places where magnetic compasses stop working.

They are -----

1.  Earth's magnetic poles 

                At magnetic poles, Earth's magnetic field runs almost vertically instead of horizontally.

               This makes compass needles to dip downwards.  It often spins or points randomly.

2.  Bermuda triangle 

               In this place in Atlantic ocean, compass fails.   Here we can observe unusual magnetic variations.

3.  Kursk's magnetic anomoly, Russia 

                In this region, large amounts of iron ore deposits are found.  This creates strong local magnetic pull which overpower Earth's natural field.

4.   South Atlantic anomoly 

           In this region, Earth's magnetic field weakens.  It also affects satellites and electronic signals.

5. Kerguelen plateau 

             This underwater volcanic plateau has unusual magnetic properties which distrubs Earth 's magnetic Field.

Why is America called United States ??

 The name United States of America is commonly shortened to USA.

Before independence, the land now known as United States consisted of 13 British colonies along eastern cows of North America.

These colonies differ in culture, economy and governance, yet they shared growing dissatisfaction with British rule.

When they decided to break away from British crown, they faced a crucial question  ---  "  How could seperate colonies unite, while still maintaining their individual identities ??  "

After declaring independence in 1776, the former colonies  merge into a single centralized territory.

Instead they formed a union of individual states, each with its own government and law, while agreeing to be governed collectively on national matters such as defence and trade.

So,  America is called USA because the name accurately describes the nation  :  A Union of individual states located in America   !!!

Bheja Fry question

 This Bheja Fry question don't require mathematical knowledge  !!!

Question 

If          9999  =  4

             8888  =   8

             6688   =  6

Then     4466  =  ??

Answer 

Please don't try to put mathematical formulae over here !!!

Just look at the number 9.

It is having one circle in the upper part  !!!

In the first row, we have 9999.  So,    4 circles.

Now look at the number 8.

It is having two circles on both upper and lower parts   !!!!

In the second row,  we have 8888.. So,   8  circles.

Same way,

In the third row, we have  6688.

Total number of circles in the number 6688 is     6.

On the same logic, 

In the fourth row we have   4466.

Number  4  don't have circles, it has only empty  space !!!

But number 6 has one circle in it.

Number    4466 has   2     6s.

Total number of circles       only     2     !!!!

Hence  9999        4

              8888         8

                6688            6

                4466            2
