鉃★笍

Some substances or elements like Germanium, Silicon, carbon etc. are neither good conductor of electricity not good insulator. Their conductivity and resistivity lies between conductors and insulators. Such substances are known as Semiconductors.

.

鉃★笍

A semiconductor becomes a perfect insulator at zero temperature. However, when the temperature rises the electrons of the valence shell absorb the heat and they jump into conduction band or shell. So, its conductivity increases and resistivity decreases with the temperature. This property is known as 11Negative Temperature Coefficient|| of resistance.

.

鉃★笍

鈼 USES AND APPLICATIONS OF SEMICONDUCTORS:- 鈥 Building blocks of logic gates.

鈥 Transistors( which are the base for the CPUs, GPUs, amplifiers and many other applications).

鈥 LEDs(light-emitting diodes) which are used in displays and room allumnation.

鈥 Solar Cells which are used in solar panels.

鈥 History behind the discovery and theories of 鈥淎toms鈥..!!………………….

鉃★笍As we mentioned in our last post about Democritus (460-370 BC) and his word 鈥淎tomos鈥. Democritus said that matter is made up of some type of indivisible particles and he used the word 鈥淎tomos鈥 for describing those indivisible particles. So, on that time Democritus was quite right about the idea regarding 鈥淎toms鈥 but, exactly wrong about the divisibility of 鈥淎toms鈥 as per our #knowledge nowadays.

.

.

鉃★笍Later, almost in the year of 1803, an English #chemist John Dalton started to develop a #scientific #theory regarding 鈥淎toms鈥. Swipe left the picture given above to know about the six major statements of given by Dalton in his atomic theory.. .

.

.

鉃★笍In late 1800, some famous scientists Neils Bohr, J.J.Thomson, Ernst Rutherford and so many other scientists developed many models regarding atoms. We would learn all those models later in our upcoming posts… .

.

.

鈥 What are 鈥淎toms鈥 Nowadays ??………

鉃★笍All type of matter is made up of 鈥淎toms鈥, which means 鈥淎toms鈥 are the fundamental particles of matter. And one most important thing is that; 鈥淎toms鈥 are also #divisible… .

.

.

鈥 If 鈥淎toms鈥 are really divisible 鈥. Then which particles or what makes an 鈥淎tom鈥 ??……… 鉃★笍鈥淎toms鈥 are really divisible as we mentioned earlier. Atoms are made up of a 鈥淣ucleus鈥 and 鈥淓lectrons鈥. The nucleus is present in the centre of an Atom and the electrons revolve around the nucleus. Nucleus is also divisible. 鈥淧rotons鈥 and 鈥淣eutrons鈥 are known as 鈥淣ucleons鈥 as they make up the nucleus. We would learn about 鈥淧rotons鈥, 鈥淣eutrons鈥, and 鈥淓lectrons鈥 in #brief later in our upcoming #posts.

鈥 What is 鈥淢atter鈥??

鉃★笍Our universe is made up of matter. In fact, anything or every single thing in this observable universe is made up of a particular material, and scientists named that material 鈥淢atter鈥. For some daily life examples; the air you breathe, the food you eat, the stars you see in the night sky while remembering your ex鈥r the pets you play with or we humans鈥︹e all these things are 鈥淢atter鈥.

.

.

鈥 Lets dig a little bit past behind the term 鈥淢atter鈥!!聽

鉃★笍In ancient times, Indian philosophers used to believe that 鈥淢atter鈥 is made up of five materials or five tatvas and they described it by a new term i.e., 鈥楶ancha-Tatva鈥欌 鈥楢ir鈥, 鈥楨arth鈥, 鈥榃ater鈥, 鈥楩ire鈥, and 鈥楽ky鈥. But, later the Greek philosophers excluded or removed 鈥楽ky鈥 from the list.

A famous Greek philosopher Democritus once told that all matter contains some tiny particles and those particles are so small to be differentiated from one another. He also said that it is impossible to break down these particles into more smaller pieces. He also coined a new term 鈥淎tomos鈥 for describing these indivisible particles, which simply means 鈥業nvisible鈥. Swipe the image and read the second slide for more history.

.

.

鈥 What is particulate nature of 鈥淢atter鈥??

鉃★笍As we mentioned earlier the statement by Democritus, that all 鈥淢atter鈥 contains some tiny particles, so exactly like this 鈥淢atter鈥 is not continuous but particulate. For an example, if you throw a glass sheet on a floor or if you tear a page of you notebook in small pieces then the glass sheet or the page is going to be vanished but would change in small pieces. It shows that each and every matter is made up of some particles which we call 鈥淎toms鈥.

鉃★笍Usually, we divide the nature and science into two worlds; first one is Macroscopic World and the second one is Microscopic World.

鉃★笍The macroscopic world contains the things we can see with our eyes. The microscopic world contains the building blocks of matter, the atoms and molecules. We know they are there, but we can’t see them directly.

鉃★笍The mesoscopic world is in between the microscopic and the macroscopic world. The boundaries are not sharp, but can be roughly indicated. Mesoscopic and macroscopic objects have in common that they both contain a large number of atoms.

鉃★笍聽A difference is that the macroscopic object obeys the laws of classical mechanics, whereas the mesoscopic object is so small that these laws no longer hold. Mesoscopic and microscopic systems both belong to the wonderful world of quantum mechanics.

鉃★笍Mesoscopic physics addresses fundamental physical problems which occur when a macroscopic object is miniaturized. This field originated almost ten years ago, motivated largely by the electronics industry.

鉃★笍When we talk about electricity so majorly we differentiate the things and matter in two different types; i.e., 鈥楥onductors鈥 and 鈥業nsulators鈥. Now, conductors are those metals or things that can conduct electricity or transfer electrons from one place to another like; ( copper, silver, etc鈥).

.

鉃n the other hand, insulators are very bad conductors of electricity like; ( wood, plastic, etc..). But, as we know that there is no state of resting in the field of Science so, in the early of 20th century some scientists demonstrated some experiments.

.

鉃★笍They developed some new laboratory techniques to cool materials to the temperatures near 鈥淎bsolute zero鈥 (-273 掳C), and began investigating how the ability to conduct electricity changes in such extreme conditions.

.

鉃★笍In some simple elements like;( mercury and lead ) they noticed something remarkable 鈥 that below a certain temperature these materials can conduct electricity with no resistance. This amazing phenomenon either in 鈥楥onductors鈥 or in 鈥業nsulators鈥 so this led to an establishment of a very new state of matter known as 鈥淪uperconductor鈥.

.

鉃★笍A 鈥淪uperconductor鈥 is a material that can conduct electricity or transfer electrons from one place to another place ( One atom to another atom ) with any kind of resistance or wasting any little amount of energy. That mean no sound, no heat and any kind of energy loss woould not take place during the transfer. We had posted about 鈥淨uantum Levitation鈥 on last Thursday, a 鈥淪uperconductor鈥 was playing a very essential role in that phenomenon. So, by the help of this post you would be able to relate.But, this 鈥淪uperconductivity鈥 is only possible in extreamly low temperatures. So, many researches are going on for getting a break

Hey going to some electric part! As it鈥檚 also an important part of the physics! We鈥檙e having a look in the inductor part!

.

鉃★笍An inductor is a passive electronic component that stores energy in the form of a magnetic field. In its simplest form, an inductor consists of a wire loop or coil. The inductance is directly proportional to the numbers of turns in the coil. Inductance also depends on the radius of the coil and on the type of material around which the coil is wound.

.

鉃★笍US scientist Joseph Henry (1797-1878) invented his coiled around various iron shapes. The standard unit of inductance is the 鈥淗enry鈥 abbreviated as (H).

.

Q.] Why do we use inductors?

鉃★笍 They are used to block AC while allowing DC to pass; Inductors designed for this purpose are called chokes. They are also used in electronic filters to separate signals of different frequencies, and in combination with capacitors to make tuned circuits, used to tune radio and TV receivers.

As the name is already suggesting that is this phenomenon is related to the to the laws of “Quantum Mechanics”. “Quantum Levitation” is a process in which scientists or the researchers use some properties of “Quantum Physics” to make an object ( specially ; superconductor) fly or levitate over a magnetic source.

.

This phenomenon of “Quantum Levitation” takes place because of a very well known theory or effect i.e., “The Meissner Effect” or “Magnetic Flux Pinning”. “The Meissner Effect” states that a superconductor in a magnetic field would always expel the magnetic field from inside of it which would result in the bending of the magnetic field around that superconductor. If you just placed a superconductor on top of a magnet, then the superconductor would definitely float off the magnet, trying to balance two south magnetic poles of bar magnets against each other. “Superconductivity” and “Magnetic Field” do not like each other. The superconductor would expel all the magnetic field from inside. This is the process known as “Meissner effect”. The same process is responsible for the “Quantum Levitation”.

It is my observation and experience as well that whenever I study astronomy so I feel so relaxed and a different connect, that just make me forget all the my extra desires and wishes. When I study astronomy I do not read only about the information of planets, stars and different theories, but I peep inside the past or the existence of our universe.

We all are star stuff and still we are connected but we can鈥檛 see that connect but feel it as the genius 鈥淣ikola Tesla鈥 said, just like that I feel that connection and yes this provides me the satisfaction , A kind of satisfaction that not any other thing can ever provide me.

鈥淧ositron鈥 is a part of matter which means; it is a sub-atomic particle. 鈥淧ositron鈥 is also known as 鈥楢nti-Electron鈥 or 鈥楶ositive Electron鈥. Well, there is a very simple or genuine reason is there behind both of these names of 鈥淧ositron鈥. 鈥淧ositron鈥 possesses the mass and the charge exact same as the sub-atomic particle 鈥楨lectron鈥. The only difference between a 鈥淧ositron鈥 and an 鈥楨lectron鈥 is that; an 鈥楨lectron鈥 possesses a negative charge whereas the 鈥淧ositron鈥 possesses a positive charge. The combination of an electron and a positron results in an annihilation which transforms both particles into high-energy photons.

The existence of the Anti-Particle,鈥漃ositron鈥 was predicted by Paul Dirac in 1928. It was later discovered by an American physicist Carl David Anderson in 1932, 4 years after the prediction. It was the very first time in the history of 鈥楺uantum Mechanics鈥 that a particle was predicted before the proof of existence. 鈥淧ositrons鈥漵ometimes generated naturally and also can be produced artificially, by some radioactive decay of certain isotopes like carbon-11, potassium-40, aluminium-26, iodine-121, etc.

A 鈥楶roton鈥 is 1837 times heavier than an 鈥楨lectron鈥.If we talk about the time before the discovery of 鈥淧ositron鈥 so, people used to think that the 鈥楶roton鈥 is positive and the 鈥楨lectron鈥 is negative naturally. And, many questions were asked by many people that; 鈥淲hy the 鈥楶roton鈥 is heavier than the 鈥楨lectron鈥?鈥 or 鈥淲hy a 鈥楶roton鈥 doesn鈥檛 possess negative charge and why an 鈥楨lectron鈥 doesn鈥檛 possess positive charge?鈥 The discovery of a positive electron(Positron) by Anderson was the first evidence of these particles which were symmetrical to the particles of our everyday world (Electrons & Protons). They belong to what is now known as antimatter.

In 1932, when Carl Anderson discovered 鈥淧ositron鈥 for the very first time so, it was quite impossible for the scientists to demonstrate the existence of a 鈥淧ositron鈥. On that time developed particle accelerators were not there so they waited for a long time to demonstrate. In 1955, the team of Emilio Segre and Owen Chamberlain using the Bevatron, the new accelerator at Berkeley (California), proved the existence of the antiproton, and then shortly afterwards that of the neutron antiparticle, the antineutron. And, not only they demonstrated it but also won the 鈥淣oble Prize鈥 for it.

The positron does not exist in our environment. According to the Einstein鈥檚 famous equation [E = M C虏] relating mass and energy, it is quite possible to produce positrons with energy greater than 511 kEv, which is total the mass energy of a positron or an electron. One may create simultaneously one antiparticle. In the process, the total electric charge should be conserved.

Pair production is observed in nature when a photon or an energy wave packet, of greater than 1.02 mEv passes near the electric field of a large atom such as lead, uranium or other heavy material with a large number of protons (around an atomic number of 80 or 90). In this process the photon is literally split into an 鈥楨lectron鈥 and 鈥淧ositron鈥. Both have a rest mass energy equivalent of 511 kEv.

Now, after all these experiments and demonstrations still thousands of questions keep striking the brains of Science Enthuthiasts that; We know that each and every matter contains millions of millions of millions of electrons, now we have come to know about 鈥楢ntimatter鈥 or 鈥楢ntiparticle鈥 of an 鈥楨lectron鈥 too. But, the thing is that as much electrons are present in our observable universe 鈥楢ntimatter鈥 like;(鈥淧ositrons鈥, 鈥楢nti-Protons鈥 and 鈥楢nti-Quarks鈥) are not present. WHY????

It may possible that 鈥淎 different universe is also there, totally opposite of ours, full of 鈥楢ntimatter鈥 or 鈥楢ntiparticles鈥 and thwy are searching for 鈥淢atter鈥 which would be 鈥楢ntimatter鈥 for them鈥, or 鈥淥ur current technology for searching these particles are not too developed for tracing them鈥. Experiments have shown that a perfect symmetry between 鈥楶articles鈥 and 鈥楢ntiparticles鈥 is not accurate or exact in the field of the weak forces responsibles in particular of beta radioactivity. Can this asymmetry ,which is very very small, can be the explanation for the absence of 鈥楢ntimatter鈥 around us ? Who Knows鈥︹︹︹hese questions are very vital in the field of Particle Physics.

猞 WHAT IS RELIGION ??

:- When you google 鈥淲hat is Religion?鈥 then you get the result 鈥楢 particular system of faith and worship.鈥 But, its not too easy stuff to understand鈥.Religion is the way or path of system of beliefs about divine. Religion is the way to perform good deeds. Some people are spredind some wrong knowledge regarding religion. But, if you wanna understand what religion actually is so you should read scriptures instead of believing anyone. Religion can answer some big and great questions. Religion doesn鈥檛 contradict the laws of science. .

猞 WHAT IS SCIENCE ??

:- The word 鈥淪CIENCE鈥 originated from the verb 鈥楽cientia鈥 which means 鈥渢o know鈥. Science is the concerted human effort to understand, the history of the natural world and how the natural world works, with repeated process of Theories, Observations, and Experiments. Science is both a body pf knowledge as well a process. Science is continually refining, developing and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation. So, Science will never be “finished.” .

猞 WHY SCIENCE CONTRADICTS THE RELIGIONS IN PRESENT WORLD ??

:- Actually we know very well that , the present world is a world of selfish peoples. Science can鈥檛 contradict the views of religion as Science and Religions are two facets of a single coin. People, some astrologers, hypocrite saints make Science as a contradiction of Religion for their own profit and all. Above picture is not for insulting any Religion but it is just showing that Science always save us from fake religion.

猞 What Is Lagoon Nebula ??

:- The lagoon nebula is (also known as messier 8 or m8, ngc 6523, sharpless 25, rcw 146, and gum 72) is a giant interstellar cloud in the constellation sagittarius. It is a type of emission nebula and an h ii region. It is located at 1250 parsecs (4080 light-years) from the solar system. The lagoon nebula is approximately 10 parsecs in diameter i.e., (33 light-years) in diameter.

.

.

猞 NASA鈥檚 Hubble And The Lagoon Nebula..!!

:- On the 28th anniversary of nasa鈥檚 hubble telescope i space, it took the image of the lagoon nebula. The lagoon nebula is almost 20 light years tall. The images of lagoon nebula we have posted these all pictures are showing only a small part of this turbulent star formation region. The observations were taken by hubble鈥檚 wide field camera between 12 feb. And 18 feb. 2018.

鈼 What is an Einstein-Ring ??

:- Einstein-Ring is an outer-space phenomenon. Einstein-Ring is also known as Einstein鈥揅hwolson ring and Chwolson ring. According to聽general relativity, gravity causes a聽deflection of light聽by the gravitational field of a massive body ( Gravitational Lensing ). In this case, a galaxy bends the light that is emerging from a galaxy that is directly behind it, focusing the otherwise divergent light into a visible ring.

This ring is named an Einstein ring, after the person who discovered the relativity theory whom we know very nicely. The favourite genius of the world Albert Einstein 鉂も潳. But, remember that,this occurs only when the source, lens, and observer are all aligned.

.

.

鈼 What is Gravitational Lensing ??

:- Gravitational lensing is predicted by聽Albert Einstein’s theory of聽general relativity. In this case, light is got bent because of the presence of a massive body as it distorts the spacetime. 聽An Einstein Ring is a special case of gravitational lensing, caused by the exact alignment of the source, lens, and observer. This results in a symmetry around the lens, causing a ring-like structure.

.

.

鈼 First Einstein-Ring ….!!

:- The first complete Einstein ring, designated B1938+666, was discovered by collaboration between astronomers at the聽University of Manchester聽and聽NASA's聽Hubble Space Telescope聽in 1998.
