FIRE HAS SHADOW OR NOT?

-


Hey all ! Let us all get through a very simple and quick experiment . Many of you might have already come across this .
In a complete dark room light a candle  . You noticed the shadow of the candle on the wall but not the flame ?

 Quite interesting and surprising at the same time . Now place a torch behind the candle .



       Did you notice the Shadow this time ?


Well, Here's  a very simple explanation for it .
If the light source behind the fire is brighter than the source itself , the flame would cast a shadow .
Shadow is just a darker area which appears when an object blocks the light . Therefore, Flame doesn't cast a shadow because flame itself is a bright source of light and is mixture of many gases summing up to be transparent upto some extent

But if you look closely , you will see the bright edge of the shadow . This validates that light was not simply absorbed but was also pushed to the side where it congregate up a bit causing a  bright edge

Why do mosquitoes bite itch?

-
 People usually get bitten by mosquitoes and when mosquitoes bite, they draw out blood. while drawing blood they inject their saliva. Mosquitoes saliva contains anticoagulant and proteins.              When  this protein present in mosquitoes saliva enter in the body then it trigger body's immune system. To fight with this foreign protein substance body's immune system releases histamine (Histamine is a compound that helps white blood cells get to the affected area) It is histamine what causes itchiness, inflammation, and swelling. Mosquitoes bite itch more after scratching it. As when we scratch the affected area, It causes skin to become more inflamed. This inflammation causes skin to itch. After scratching again and again skin can break which may cause infection. One can get immediate relief by applying Aloe Vera, honey, cold tea bag, dilute minced garlic on the bite

  All of us have been to doctor or medical shops to purchase medicine for some reasons. This is a common thing. But have you ever notice that the doctors always write a word Rx on prescription before prescribing any medicine. Also, Rx is written on many medicines. The thing is, Have you ever thought why it is written so and what it means? If No, then think about it.  The popular explanation is given that, In old age Rx was related to the sign of roman god Jupiter. Jupiter was called the planet of healing.  The reason behind to write Rx on prescription and medicines that we are praying to the planet of healing (Jupiter) that the person who takes this medicine heal early.

TELEPORTATION

Teleportation is the transfer of matter or energy. Transfer from one point to another at a long distance. Thus teleportation is a peculiar phenomenon by which a person can travel a great distance in fraction of second.  I think teleportation is the most fascinating concept. As we all know about Narad Muni, he travels from one place to another within fraction of seconds. Basically on the basis of science we can say that they used teleportation. In our century, It has been observed for microscopic particle. Although it has not yet been implemented in real world (Macro particles).  Basically teleportation can be possible using the concept of quantum entanglement. Quantum entanglement  Quantum entanglement :-when the two particles (usually photons) created together,they behave like twins.Which  Means their behaviour is same and they can have same spin wave,Even without having physical connection between them. They just mimic each other even at vast distance(usually ca
