Why sprinkle water before dosa ??

  There is a very practical scientific reason for that quick splash of water !!!

The primary goal is to lower the surface temperature of the tawa quickly.

If the pan is too hot, the batter will cook the moment it touches the surface.  This makes it impossible to spread the batter into a thin circle. Batter just stick  to pan.

The reason behind this is as the water evaporates, it absorbs a significant amount of heat  from the metal.  It brings the temperature to a point where the batter can glide smoothly before setting.

The water droplets instead of just evaporating instantly, they will be dancing and skittering across the pan !!!

This is Leiden Frost effect.

When a liquid hits a surface significantly hotter than its boiling point, a thin layer of vapour forms between the liquid and the surface.

This vapour layer acts as an insulator, allowing the droplets to hower   !!!

After sprinkling the water, it is  important to wipe it off. Otherwise dosa will steam and become soggy..... 

When batter is applied to pan, batter don't get attached to pan. Also it will help the batter to spread making dosa crispier in the edges and smoother in the middle  !!!

Why do human new born babies have more bones than adults ??

Many of the new born babies " bones " are actually seperate pieces of soft, flexible cartilage that gradually fuse together as they grow.

New born babies born with 270 to 300 " bones ", an adult skeleton has only 206 bones.

Having multiple, seperate skull bones allows the baby's head to compress slightly.  It helps in natural way of pregnancy.

Flexible spots between skull bones provide room for the brain to expand quickly during infancy.

Pliable skeleton helps the infants to absorb the effect of falls and tumbles while they try to learn crawling and walking.

As the person matures, calcium and other minerals harden the soft cartilage to solid bones.

Similar bone segments grow together to form single, larger and stronger structures. 

This is notable in skull, spine and pelvis regions.

Mulla Naseeruddin and coffee

  One day,  Mulla Naseeruddin went to a coffee shop and ordered coffee.

He sipped it and made a face  !!!

He called the waiter.

Naseeruddin asked the waiter,  "  What's wrong with the coffee  ??  "

Waiter  :  It's the same coffee we serve everyone  .....

Naseeruddin   :    Then why is it cold ??

                                  Did someone drink from it already  ??!!

Why letter 'u' always comes after letter 'q' ??

 I listed out some words starting with ' q'.

In all these words, 'q’ is followed by letter 'u' !!!

Queen  

    Quiet       

          Quit   

                 Quick  

                        Question 

                               Quality 

                                    Acqua

In all these words, letter 'q' is followed by letter 'u'  !!!

Q always never hangs out alone  !!!

Why ' qu  '  happens 

1. It came from Latin .  

In Latin,, q is always followed by u

When English borrowed tonnes of Latin words, we kept the spelling.

2.  English was influenced by French too  !!! 

      As French also used same letters, English just     k   e   p  t  it .

 

U  follows   Q  because  Roman and French people did it first..

We just kept the habit  !!!

We don't really use Q alone .  It feels wrong to us.

Q always brings U, thats how we learnt it  !!!

It is just a spelling habit, that we inherited   !!!
