Ever heard people saying I never came to know about use of newton's laws or (a+b)²??

Useless stuff!!

Many would be thinking the same themselves.

*BUT WHY??*

Let me tell you, you should feel respected and honoured to be taught these. Almost everyone can be perfect in learning the newton's laws or mathematical identities, but not everyone can think big, to be more accurate, veryyy biggg to use these. The rocket you probably would have never seen is based on that law of newton which you refuse to study, the bed you sleep on, the table on which you cram those "damn identities" are based on those identities only. The mobile you use, the airplane you fly in, the buildings you live in, the bulb you turn on everytime and everything around you is possible just because of those damn subjects only.

Let's be smart enough to understand and apply those so called useless theorem, laws and identities before judging.

🖤Black has some of the blackest secrets🖤

I always wondered that why does everything turn black on burning except for my mates! 😂😂

What I said was, everything turns black on burning.

butWHY?

You know what, most of the fuels we use today are carbon based that is they have carbon in them. It's either in elemental form or combined form.

But hey, I am not only talking about LPG, petrol or diesel, anything that can burn is a fuel, be it paper, wood or a piece of cloth. Carbon plays an essential role in burning or combustion. Whenever any fuel is burnt, carbon gets deposited either on it or is carried away by smoke. This carbon is black in colour, giving the wood or paper black colour. It's not the fuel turning black, a black coat is being deposited on it giving it black appearance. The reason why smoke appear black is that it carries carbon with it.

Umm! Still have a doubt??

If carbon is involved in burning, it could have simply burnt, how come it is there to get deposited and give black colour to fuel surface?

Well, I really wanted to answer this question, but to not break the monotony, let it be a suspence.

Last question,

Diamond is also carbon based, but is it black??

FLOWERS are the most beautiful part of a plant❤❣️

butWHY??

Flowers are the sexual part of plant, would they attract males by their beauty??😆😆 Umm! Indirectly!! But they do attract someone directly, namely ✨INSECTS✨

Insects help in pollination.

They get attracted by the beauty of flowers and sit on a stick called filament which has anther on top. Anther has pollen grains. Pollen grains get Stuck to the body of insects and when they reach the female part of flower called stigma of the same flower or the another one, pollen grains get Stuck to stigma and reaches the egg. This process is pollination.

But wait,

• Is it the same reason for flowers to be scented?

• Do flowers only depend on insects for pollination, or is there any other mechanism?

!MORE TO KNOW!

The average drift speed of an electron in a conductor is 1mm/sec. Isn't it very small!

*BUT THEN WHY* a bulb starts glowing as soon as we turn on the switch??

Consider this GIF

Each stack can be assumed to an electron. As soon as the potential difference is applied, first electron starts to push each subsequent electron and so does the second, third, fourth and every following electron. The last electron when experiences the push moves and the current gets generated. It's not necessary for the First electron to reach the Bulb to make it glow.

*BUT WHY?*

A Bulb would of cource not require an electron to glow, what it needs is energy. And for energy transfer, it's not necessary for First electron of the Wire to reach the bulb. The last electron when moves, provides space of every other electron to move which generates energy and bulb glows.

And this happens far quicker than displacing an electron from starting of the wire to the end of the wire.

Ever stored water in earthen pots?

Now, we have facility of refrigerator but before people used to store water in earthen pots.

*BUT WHY?*

Earthen pots have small pores through which little water comes out and evaporates by driving heat energy of pot and water in it making water cool.

But wait, why do you think is a wet cloth wrapped around earthen pots. Does it make water even cooler?

🤍BEAUTY OF LIGHT🤍

What are blue cut glasses?

Blue light is actually harmful to our eyes. Such lenses or glasses reflect back blue light thus preventing it from entering our eyes.

But then WHY, do these lenses or glasses not look blue?? An object that reflects/emit red light looks red, one that reflects or emit green light looks green, then it should also have looked blue.

*BUT WHY NOT?*

These glasses do not emit their own blue light. Therefore, their colour depends on the amount of blue light in surroundings.

While sitting in a room with medium light, lens won't appear Blue as there's not much light to get reflected and give it Blue colour.

While you are outside in proper light, glasses do appear Blue although sunlight doesn't have enough of Blue light to give our lens a proper blue colour.

But when you keep them in front of a Tubelight or a device emitting light, they do look Blue at parts where Blue light is incident and getting reflected.

Can we answer now that why after wearing these glasses, the world looks yellowish?

Any number raised to Zero equals one i.e. x^0=1.

*BUT WHY?*

Let's look for the easiest explanation to the question.

x^0 can be written as x^(m-m) which can furthur be written as x^m/x^m, and any number divided by itself gives 1.

Now as we know why any number raised to Zero is 1, does 0^0 also equals one??
