Interesting things to know

 We all are familiar with term “clock”. In our daily life we use clock number of times to get know about time. But, have you ever wonder that how this clock works?   How it shows us time? If you know already then you are such a smart person though. But if you do not know then, no worries we will see and learn how this clock named thing works. First, let we jump into the history of clock? Who made this? There are many clocks that were invented in past. Some of them are sundials, Greek water clocks, candle clocks, hourglass etc. But here we are talking about modern clocks. Don’t know how much it is true but it is said that the first modern clock was created by a german inventor named “Peter Henlein” in 1511. Now let’s see how today’s clock works. Here I will talk about only modern clocks in which quartz is used as main component. Many of us have seen quartz written on clocks because quartz is main component in that clocks. In quartz clocks battery is used as power sour...

We all know and believe that there are three states of matter i.e solid, liquid and gaseous state. But in actual, there are four types of matter. Sounds interesting ? Yes it is, so let’s know more about this 4 th state of matter i.e Plasma. As when we heat solid it becomes in liquid state. After heating liquid, gaseous state occurs and on further heating gas; plasma state occur. Basically In plasma, gas is in ionized form but a ny ionized gas cannot be called a plasma, of course; there is always some small degree of ionization in any gas. In plasma state both ions and electrons are present.  A useful definition is as follows: A plasma is a quasineutral gas of charged and neutral particles which exhibits collective behaviour. Also there is a belief that plasma is not actually fourth state of matter but first state. It believes that in starting there was  only plasma on earth after it cooled down then gas, liquid and solid states occured respectively. It has often b...

 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

The concept of time travel can be understood by the concept of time dilation.   So what is time dilation? Time dilation , in the theory of special relativity  , the “slowing down” of a clock   as determined by an observer who is in relative motion with respect to that clock.      Or             It  is a difference in the elapsed time  measured by two clocks, either due to them having a velocity relative to each other, or by there being a gravitational potential difference between their locations. In simple language we can say that time dilation is the slowing of time. For example let a object or a vehicle is moving with very high speed (approx with the speed of light). For the person who is inside the object, the object is at rest but for the observer he is in motion. As the object is moving with speed of light the time is slow for the rider as compare to the observer. Albert Einstein in 1906...

As we all are aware about pandemic COVID-19 (coronavirus disease). It has become a huge threat to everyone from past few months. Although we all try to protect ourselves from this disease by maintaining social distancing and by doing other things like exercise,frequent hand washing,proper hygiene, eating healthy food,etc. According to Oxford study Social bubbles can limit COVID-19 better than social distancing. What is A Social Bubble?  A Social bubble is a close set of people i.e like family with whom we interact on regular basis. Keeping in mind the pandemic COVID-19 during current lockdown, a social bubble should be limited to members of a household with whom we interact on regular basis. However, as things normalise this bubble can grow larger. It can then include close friends, relatives and neighbours. In later stage it can expand further. The idea is that if people decide to expand their bubble gradually and make sure that they meet and contact only the persons of...

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 ...
