Science behind Science -Know some more

 Have you ever thought about a matter which is frictionless😮? Today you will know about such a state that is almost impossible to exist. But it can exist under certain impossible conditions. So, let's dip into the fluid which is frictionless with Science behind Science- Superfluid, the literal meaning for this word is a type of matter which is very good in deforming and very unstable. According to physics Superfluid is a substance that has the characteristics of superfluidity. In other words, a fluid that has zero viscosity and no entropy, therefore, flows without losing any of the kinetic energy. If Superfluid is stirred it forms an infinite vortex that means a never-ending vortex. Vortex In 1937,  Pyotr Kapitsa in Moscow discovered an amazing material today called superfluid. He noted many of its properties and published an article in 1938. Later he was awarded a Nobel prize in 1978 for his great achievements in low-temperature physics. Pyotr Kapitsa Helium-4 an isotope of ...

Today I want to tell you about some magnificent materials Bulletproof material means an object which can neutralize the power of the bullet. Bulletproof materials are not that much important for the common man's use. But it is very important for the defense such persons who are protecting common man like our police, army, and some great leaders. So, today lets find the science behind bulletproof materials:- Today we will discuss some amazing bulletproof materials before we start, we should know how a bulletproof material stops a bullet from being damage. If the bullet is fired at a person then the bullet will pierce through the flesh. If he is wearing a bulletproof vest or he is hiding behind a wall, wood, or any tough metal he will survive. When a bullet hits any bulletproof material then the layers of atoms present in the materials prevent the bullet from piercing it completely. The bonds of atoms present in the material give them high strength. So, the bullet comes to rest. But ...

What do you mean by density? Is it just mass / volume or some thing else. Today we will learn about density and how density increases with substance. I know all these seems much simpler for you but the series of increasing density will blow up your mind. So, lets uncover the science behind it- The term density was given by a Greek physicist and mathematician namely Archimedes. His king ordered him to state that whether some part of gold was stolen from his crown or not without breaking the crown. Archimedes was very confused to complete this task but later when he noticed that when he entered his bath tub some water got displaced from the tub. Then, he just walk out the tun and ran naked on roads in happiness. From here came the concept of Density later called ARCHIMEDES PRINCIPLE .  Density is just mass/volume in other words, how much mass content is there in a unit of volume i.e it is a measure of mass per volume. The SI unit of density is kg/m 3 and it's smaller unit is g/ cm 3 ...

Graphene an allotrope of carbon. Today with wide-ranging demands. You know whats the price of graphene. For about 10 grams of graphene, the price is ₹ 2300 ($ 31.47 price on Amazon) so, you can imagine 1 kg of graphene would be ₹ 2,30,000 ($ 3147) but what is so different in it which made it so valuable. So, let us find the science behind science -   Read this also : An unimaginable state of matter - Superfluid - truesciencebehindscience First, we should know how it is manufactured. There are five different methods to produce graphene known as Micro-mechanical exfoliation, Liquid-phase exfoliation (LPE), Chemical vapor deposition (CVD), Flame synthesis, Pulsed laser deposition (PLD). We will learn these methods on a different day.   Now, we will learn their properties Physical properties:- Graphene has a structure in which 3 electrons of carbon are connected to the other 3 carbon atoms and one electron is left free. Graphene has very little density somewhat 2.267 gm per cube c...
