It's AumSum Time
-
How were French Fries invented?
-
Don't know.
-
But let us give that inventor a dab.
-
Yes surely.
-
French fries are loved all across the globe.
-
But who exactly introduced these golden strips to the world?
-
One popular theory traces the origins of French fries to Belgium.
-
It is said that in Belgium, poor villagers living near Meuse river.
-
Often ate fried fish caught from the river.
-
However, winters caused the river to freeze.
-
Forcing villages to find alternative sources of food, thus turning towards potatoes.
-
They cut and fried the potatoes in the same way as they used to fry the fish.
-
Then, during World War I. American soldiers stationed at Belgium were given these fried potatoes to eat.
-
They absolutely loved the taste.
-
Since the dominant language of Belgium was French.
-
The soldiers named the fried potatoes as French Fries.
-
And voila French Fries were invented.
-
Comets.
-
Why do comets have tails?
-
Maybe because, like monkeys, they can hang themselves on trees.
-
No.
-
Let me explain.
-
A comet is a mixture of rocks, dust and ice.
-
This ice is basically frozen water and frozen gases.
-
When a comet approaches the sun, it starts to heat up.
-
Converting ice directly into gas and releasing trapped dust particles in space.
-
So, you mean a comet has two tails.
-
Absolutely.
-
Stop bluffing.
-
No.
-
It is true.
-
The ultraviolet radiations from the sun ionize the gas.
-
And the solar wind carries this ionized gas away from the sun, forming an ion tail.
-
Whereas, the light from the sun exerts pressure on the dust particles.
-
And pushes them away, creating a dust tail.
-
Friction.
-
Why is it difficult to pull a boat on the beach than on the sea?
-
Hey.
-
You will find it difficult to pull the boat on the beach.
-
Pull it on the sea.
-
There it will be quite easy.
-
Indeed.
-
Why not?
-
Fine.
-
Don't listen.
-
I am so tired.
-
At least now try to pull the boat on the sea.
-
It is quite easy, right?
-
Do you know why?
-
This is because of friction.
-
Friction is the force which opposes the motion of an object.
-
It always acts in the direction opposite to the direction of motion.
-
The amount of friction depends upon the texture of an object.
-
And the surface on which it is being moved.
-
Rough textures or surfaces offer greater friction.
-
As compared to smooth textures or surfaces.
-
Do you want to say that my brand new boat has a rough texture?
-
No.
-
Even though the texture of the boat is almost smooth.
-
The small particles of sand present on beach form a rough surface.
-
Hence, when we pull the boat on beach, the sand particles offer greater friction.
-
And oppose the motion of the boat.
-
Thus, making it difficult to move the boat on beach.
-
However, the sea being a liquid, forms a smooth surface.
-
Hence, when we pull the boat on sea, it offers less friction.
-
Thus, making it comparatively less difficult to pull the boat on sea.
-
Red eye effect.
-
Why do my eyes glow red in photos?
-
Because there is a devil hidden in you.
-
Stop bluffing.
-
Alright.
-
I will explain.
-
It happens because of blood vessels in our eyes and pupil.
-
Pupil is a small opening whose size is adjusted by circular muscle called iris.
-
In bright light, the iris contracts making the pupil smaller.
-
Thus, allowing less light to enter into our eyes.
-
In dark, iris relaxes making pupil larger, thus, allowing more light to enter.
-
And also exposing the blood vessels in our eyes.
-
Hence, when we take a photo in such a dark environment.
-
The flash of light from the camera floods into our eyes at once.
-
Some of this light gets reflected from the blood vessels onto the camera.
-
Before our iris can contract, making our eyes glow red in photos.
-
Air pressure.
-
How do straws work?
-
They work very hard.
-
No.
-
Straws work because of air pressure.
-
Is it similar to acupressure?
-
No.
-
Air pressure is weight of air pressing down on earth and all other objects present on it.
-
Now, when a straw is in a liquid.
-
The air pressure upon liquid in glass and air pressure upon liquid in straw is similar.
-
Causing the levels of liquid to be almost equal.
-
However, when we drink the liquid through straw.
-
We first inhale causing the air from the straw to flow into our lungs.
-
Now due to absence of air, the air pressure in the straw decreases.
-
Hence, air pressure present on the liquid of glass pushes the liquid into the straw.
-
Causing it to move upwards and thus, helping us drink.
-
Pneumonia.
-
What causes pneumonia?
-
The letter P.
-
No.
-
Pneumonia is a lung infection caused by microorganisms.
-
Which generally leads to difficulty in breathing.
-
Normally, we inhale oxygen rich air which reaches our alveoli.
-
Alveoli are surrounded by blood capillaries.
-
Here, the oxygen through the walls of alveoli diffuses into our blood.
-
However, sometimes we also inhale harmful microorganisms.
-
Mostly, the cilia and mucous in our respiratory tract trap these microorganisms.
-
Which are then expelled while coughing.
-
But sometimes, the microorganisms do not get trapped and reach the alveoli.
-
There they start to multiply, causing lung infection, i.e., pneumonia.
-
Oh no.
-
Now what to do?
-
Now, to protect ourselves, the immune cells start attacking the microorganisms.
-
Causing inflammation and accumulation of fluid in the alveoli.
-
As a result, the inhaled oxygen cannot get easily diffused into blood.
-
Thus, causing difficulty in breathing.
-
Bad breath.
-
Why do we get bad breath?
-
It is not bad breath.
-
It is perfume.
-
Gross.
-
Bad breath is generally caused by bacteria that live in our mouth.
-
These bacteria feed on food particles which get stuck in our teeth, gums and tongue.
-
They breakdown the food particles into simpler forms.
-
Releasing foul smelling compounds such as hydrogen sulfide, methanethiol.
-
And cadaverine.
-
These gases form the bad breath.
-
But why is morning breath so bad?
-
Usually during the day.
-
Saliva carries the food particles and bacteria from the mouth into our stomach.
-
Thus, controlling the bad breath.
-
However, when we sleep, we produce less saliva, making our mouth dry.
-
This increases the growth of bacteria, thus increasing the breakdown food.
-
And producing bad breath in the morning.
-
Why does sunlight make you sneeze?
-
Because sun teases our nose.
-
No.
-
Wait, I will explain.
-
Sneezing caused by sunlight or bright light is called photic sneezing.
-
According to a prevailing theory.
-
It happens because of a thick nerve bundle called the trigeminal nerve.
-
The trigeminal nerve detects or senses irritants in our nose.
-
And thus, triggers sneezing to expel them out.
-
The trigeminal nerve lies quite close to the optic nerve.
-
Which sends visual information from our eyes to the brain.
-
Now, in some people this optic nerve is over sensitive.
-
Just like me, right?
-
Just listen.
-
When bright light suddenly stimulates the optic nerve.
-
The optic nerve mistakenly transmits some signals to the nearby trigeminal nerve.
-
Hence, the trigeminal nerve misinterprets this signal as an irritant in the nose.
-
And thus, triggers sneezing.
-
Why do mosquitoes bite only some people?
-
Because they are lazy.
-
No.
-
There are a number of reasons why some people are more prone to mosquito bites.
-
One of them is body odor.
-
Millions of bacteria which live on our skin produce various gases.
-
These gases form our body odor.
-
Some of these body odors attract the mosquitoes.
-
So, this is the reason why mosquitoes prefer me.
-
Besides this, a popular research found that.
-
Mosquitoes tend to bite people with Type O blood.
-
Nearly twice as often as those with Type A. Exercising can also entice mosquitoes.
-
This is because when we exercise, we release more carbon dioxide, heat and sweat.
-
Mosquitoes can detect this carbon dioxide and heat.
-
They can also sense various substances in our sweat such as lactic acid.
-
Thus, making us more likely to get bitten.
-
Why are flamingos pink?
-
Wait, I will explain.
-
A baby flamingo is not pink.
-
It is actually born with grey feathers.
-
So, does it spray paint itself with pink color?
-
No.
-
Flamingos get their pink or orange color from their food.
-
Which is mainly algae and shrimps.
-
These organisms contain carotenoids.
-
Carotenoids are reddish orange colored pigments.
-
When a flamingo eats algae and shrimps, its liver extracts the colored pigments.
-
The pigments are then absorbed by fats.
-
These fats start depositing in the flamingo's growing feathers.
-
Which eventually cause the flamingo to turn pink or orange.
-
Now, an interesting fact is that we also eat fruits that contain carotenoids.
-
Such as carrots, apricots, mangoes, etc.
-
But we do not eat enough of these fruits for them to affect our skin color.
-
Why do dogs wag their tails?
-
Because they are happy.
-
A dog's wagging tail does not always mean that it is happy or excited.
-
So, what does it mean?
-
Popular researches and studies over the years suggest that.
-
The tail position and wagging direction represent different feelings or moods of dogs.
-
When the tail is hung down in its natural position.
-
It means that the dog is calm and is not worried.
-
If the tail is curled in between its legs, it indicates that the dog is scared or anxious.
-
When the tail is straight up, it indicates that the dog is curious.
-
Or wants to show other smaller dogs that it is bigger and dominant.
-
Moreover, if the tail wags towards right.
-
The dog is expressing positive emotions such as joy, excitement, etc.
-
However, if it wags towards left.
-
It conveys negative emotions such as anxiety, stress, etc.
-
Why is yawning contagious?
-
Because everybody wants to sleep.
-
No.
-
There are a couple of theories which explain why yawning is contagious.
-
One of them suggests that it is a sign of empathy.
-
Empathy is the ability to understand and share others feelings.
-
For example, when people around us are happy and smiling.
-
They make a positive impact on us.
-
Hence, we also feel good and begin to smile.
-
Moreover, the closer we are to someone such as our parents or friends.
-
The more likely we are to catch their yawn.
-
That is awesome.
-
Another theory suggests that mirror neurons present in brain make us copy.
-
Or mimic actions performed by someone else.
-
Hence, when we see people around us yawn, our mirror neurons get activated.
-
Thus, making us mimic their yawn.
-
We may have evolved such characteristic to promote social bonding.
-
Why do elephants have big ears?
-
To fly.
-
Not at all.
-
Ears basically help to hear.
-
Besides this, big ears of the elephants also help it to regulate its body temperature.
-
But how can ears help to regulate body temperature?
-
In living beings like elephants, blood supplies heat to all parts of the body.
-
Thus, helping it to maintain the body temperature.
-
However, due to metabolic activities or hot climate.
-
Sometimes heat in blood can increase, thus increasing body temperature of elephant.
-
Now an elephant's big ears are filled with blood vessels.
-
Which are very close to the surface of the skin.
-
Hence, when blood having more amount of heat flows through ears of elephant.
-
The heat from the blood escapes into the atmosphere.
-
Cooling the blood and in turn cooling the elephant.
-
How do glasses work?
-
They work very hard to make us look intelligent and studious.
-
No.
-
When light from an object reaches our eyes, the cornea and lens refract the light.
-
In a person having perfect vision, the refracted light is accurately focused on retina.
-
The retina then sends information to the brain, informing it about the object.
-
However, in some people, the light does not get properly focused on the retina.
-
Causing blurry vision.
-
When light gets focused before the retina, the defect is called myopia.
