Which one is better for eyes ?? Yellow or the white light ??

 Both light types feel normal   !!!

But they affect and comfort the eyes differently.

The right choice depends on what we are watching.

White light or daylight tone keeps the brain alert and improves concentration.

It is better for studying, working and reading.

 

Staring at bright white light for long hours can lead to headache, digital fatigue and dry eyes at night.

Yellow light feels gentler on eyes. It reduces strain and creates calm environment.

It helps brain to wind  down and supports better sleep.

SO WHICH IS BETTER  ??

Neither of colours are universally better !!!

It depends on use.

White light for focus and task.

Yellow light for comfort and rest  !!!

Bheja Fry Question

  Question 

A sleeper bus caught fire because of collision with container truck.  There were 31 passengers and 1 driver on the bus.

If the time for each passenger to get down is 30 secs, in how many minutes did the bus get engulfed in flames ??

​

​Answer 

We add the passengers and the driver together:

​Passengers: 31

​Driver: 1

​Total People : 31 + 1 = 32

​

If each person takes 30 seconds to exit, we multiply the total number of people by the time per person:

Time  =  32  ×    30  =  960 seconds. 

A minute has 60 seconds. 

==>>  Time  =  960/60 

==>>  Time  =  16  minutes

So it takes total  16 minutes to passengers to come out of the bus one by one   !!! 

Bus got engulfed in fire in nearly 16 minutes......

Vulture bees

 Vulture bees also known as carrion bees are stingless bees.

They are native to central and south America.

They DON'T FEED ON NECTAR AND POLLEN.

They feed on ROTTING MEAT  !!!!

They have  strong and powerful mandibles.

They have evolved an extra tooth, allowing them to efficiently tear off chunks of meat.

As they are stingless, they defend their colony by biting aggressors.

They often enter dead animals through eyes, nose or mouth to access the flesh.

The flesh they collect is consumed and then regurgitated upon return to the hive.

They produce an unique, protein rich substance from the processed meat which is known as MEAT HONEY  !!!

They also collect extra floral nectar.

3. Horses remember everything, good or bad !!!

4.   Horses can see almost everything around them.

5.  Horses' body movements say more than sounds.

Metal that is liquid at room temperature

We typically associate metals with being solid, heavy and structurally rigid.

But there is an exception.

Metal that is liquid at room temperature is Mercury,  Hg known as quick silver.

The reason why mercury stays liquid whereas its counterparts like gold and thallium are solids lies in quantum mechanics.

In mercury atoms, electrons move at incredibly high speeds. This causes the electrons to gain mass and pull closer to nucleus.

Outermost electrons are moved so tightly towards the center that they do not bond easily with other mercury atoms.

Because of this, attraction between mercury atoms is so weak that in room temperature also, atoms will be sliding past one another resulting in liquid state.

Mercury don't flow like water though it is a liquid  !!!

It has extreme high surface tension causing it to form silver beads, we are familiar with.
