Why do AC blast in summer. ??

  Though this type of incidents are rare, if occurred it is primarily due to pressure buildup and overheating due to excessive load.

In summer, high temperatures 45 to 48 degree Celsius, it forces the outdoor unit to work harder to cool the refrigerant gas.

This can lead to system failure if not property maintained.

Running AC continuously for 20 to 24 hours without break puts extra load on compressor.

If the compressor is already under direct sunlight and lacks proper ventilation, risk of blasting is more.

Dirt accumulation, electrical faults and improper installation are the other reasons.

Avoiding running the AC at a stretch not more than 8-9 hours and regular services are the critical safety precautions to be taken.

Fascinating things about rhinoceros

  1. Rhino horns are made of keratin 

                       Rhino horns are made of keratin, the same substance found in human hair and nail. This makes the horn strong but flexible.

2. Male rhinos are called bulls.

      Females are called cows.

      Young rhinos are called calves

      Group of rhinos are called crash.

3. Rhinos have 3 toes in each feet,, which help support their massive weight.

4. Rhinos have sensitive skin, so rolling down in mud helps them from Sun and biting insects.

5. Female rhinos have one of the longest pregnancies among land animals lasting 15 to 16 months.

6. Rhinos are living long before human appeared.

7. Rhinos can run very fast.

8. Eyesight of rhinos is weak.

9. Baby rhinos stay with their mothers for years !!!

How do solar winds form ??

  When the extreme heat in Sun's outermost atmosphere, energises charged particles to the point where they can overcome Sun's gravity, then escape into space.

At this time, solar winds are formed.

This continuous stream of plasma, expands outward to fill the entire solar system.

Magnetic fields in the solar atmosphere play a crucial role in accelerating these particles.

When solar wind reaches earth, our magnetosphere deflects most of it. However some particles leak through near the poles.

These particles collide with atmospheric gases, to create Auroras.

Intense gusts can also create geomagnetic storms which can disrupt satellites and power grids 

The inhuman way

 Once Mulla Naseeruddin stole into a farm to fetch some melons.

But owner of the farm spotted him. 

Owner asked Naseeruddin for the reason to come ?

Naseeruddin lied that he has come to relieve himself from the nature 's call !!!

Owner didn't believe Naseeruddin. 

Owner asked Naseeruddin to show the place where he has done it  !!!!

Naseeruddin showed a heap of cow dung. 

Owner protested saying it as cow dung !!!

Naseeruddin shot back saying, 

" you didn't allow me to do in the human way. What to do ???!!!!" 

Why all animals look same and humans different ??

  Animals identify each other through scent or sound.  Humans identify each others by their face.. 

Animals are far more diverse than they appear.  They look same to us because of lack of training of our brain.

Our brains are not evolved to pick up minute details between two animals. So brain categorize them as " identical  "  !!!

Humans look different because we rely on visual recognition for survival and social bonding  !!!!
