From SAND to SILICON
As we can see in the past or in the vedas sand has most powerful properties and can be said that there is whole world in the sand. We can see life, death, water and also most valuable minerals, so the sand is most valuable thing. There are many types of sand but every sand is not the same and every sand can be used in different ways. We can specifically talk about the substance Silicon and it has a very special position in the industrial usage. We are all connected to the sand and so we have obtained all things from the sand. In today’s superfast world there is a need of very complex technology and very advance chips of silicon wich is made from the silica rich sand. In this technology competitive world there are many firms who make high end processors and super fine processors. But the big firms like Intel and AMD and the prime competitors. The making of the processors is very complex. Before the fast technology of processing speeds the technology was weak and the work became very tiresome. Now this technology have become very advance with the help of big machines and has given the ultimate performance with the compact architecture.
Let’s see the process behind this achievement:
A silicon wafer is basically a slice of purified silicon on with silicon chips are built and arranged in a grid formation. This is part of a series of steps involved in the making of the silicon chip. It all begins when silicon is first purified, melted and then cooled to form ingots. These ingots are then sliced into silicon wafers which upon completion can now allow the doping process to begin. Doping is a process whereby special impurities are added on to the silicon to give it the desired semi-conduction capabilities. However, before the doping procedures can begin, the wafers have to be buffered in order to get rid of any dirt that might have accumulated during the cutting process. The surface of silicon wafers is then marked out into small identical rectangular zones that will serve as individual chips. This is followed by the creation of numerous components on the chips through the doping process which could number into thousands and even millions.
The components made can either be p-type components or n-type components. Doping can be done using different procedures. One well known one is called sputtering. This involved firing the doping components at the silicon wafer in a manner resembling how you’d fire bullets from a gun. It should be mentioned, however, that this is a very delicate and sensitive process that occurs at a very minute level. Therefore substances such as dirt and dust can be detrimental to the process. It is for this reason that the whole process is undertaken in spotless facilities called clean rooms. Technicians are also expected to wear special suits that are meant to prevent lint, hair, dust or any other substances from jeopardizing the process. This is to ensure that all silicon chips are of high quality and that they suit the desired application.
Let’s see some uses:
A silicon chip is an integrated circuit that serves as the primary component of all computing devices. As the name suggests, silicon chips are made primarily from silicon. A substance that is only second to Oxygen in being the most abundant substance on earth. Silicon is valued for its properties of semi-conduction and how conveniently available it is all over the globe. Qualities that make it the perfect raw material for making chips and silicon wafers that facilitate the manufacture of the many devices we use today. Silicon chips are the brain of the device; directing all its functions through its in-built components. Examples include tablets, smart phones and laptops.
This was a concept by Intel.
From SAND to SILICON
Dyson Sphere and Solar Power: The Future of Human Civilization
In future, when human civilization will colonize other planets in the solar system we will require ungodly amount of energy and we can it get it through our Star ‘Sun’. Yes, Sun is the ultimate source of energy. It is 100 quintillion times more powerful than our nuclear reactor. It shines with the energy of a trillion nuclear bombs per second.
So, do you know how can we get its whole energy? Not some of it, as we get through solar panels! For getting its whole energy we’ll have to build a mega structure called as ‘Dyson Sphere’.
Currently, we are slowly moving towards renewable energy and if human civilization doesn’t get destroyed due to our own petty politics or due to nature, we’ll be able to create a ‘Dyson sphere’.
It is a cosmic and hypothetical mega structure known as ‘Dyson sphere’. This Dyson Sphere has power to consume the total energy of Sun.
So,what woud it look like?
A solid shell enveloping the Sun is probably not the way to go. A large rigid body like that would be vulnerable to impact. Possibly it would be liable to drift and could also crash straight into the Sun. A practicable design for this mega structure can be a ‘Dyson Swarm’.
Dyson swarm is an enormous set of many orbiting panels that collects the Sun’s power and beam it to any other place.
Such thing will give humanity unlimited source of energy. But have you ever thought why we still didn’t make it? Sun holds 99.8% of the solar system’s mass and if we compare Earth to Sun, Sun is 109 times the diameter of Earth. So we would need many satellites for it. Suppose size of each satellite is 1 sq.km we’d need around 30 quadrillion for surrounding the mighty Sun!
Also we need the energy to actually put the parts together and also to deliver them to their specific positions around the Sun. So, currently its impossible for humans to make ‘Dyson sphere’.
This mega structure has its mini version.
Yes this structure is mini version of Dyson Sphere. (This structure also isn’t made by humans still but after 200 or 300 years we can make this structure) As satellite orbits the Earth, this structure will also orbit the Earth and they will absorb Sun’s energy. As satellite sends us signal in the way it will send us solar energy and looking at the speed of human’s advancement in technology approximately after 100 or 200 years such satellite will be orbiting our Earth and this will be our need in future because at that time we’ll lose most of the energy sources like Petrol, Diesel, Coal, etc. present here on Earth and also it will help us to get energy on other planet too!
This mini version of Dyson Sphere has its mini version too! and the good thing is it is made by humans!!!
This is it ‘Solar Panels’ a device which can transform some of the sun’s heat energy into our electricity and this Solar Panels which you seeing now aren’t just Solar Panels they will be our necessity in our future.
In the end I would like to say that human civilization will be totally depended for energy sources on these structures.
Hope you have found this interesting!
The Creation Story
The Creation Story
As Albert Einstein said, “The important thing is to never stop questioning. Curiosity has its own reason for existence.” This curiosity leads us to many great ideas, innovations, and discoveries, basically everything we see around us. It raises many unanswered questions too. As our universe is very vast and old and keeps expanding further and faster. But we don’t know the exact reason behind the expansion. Astronomers suggest many possibilities but none could stand strong expect a few.
In ancient time astronomers thought the earth was the center of the universe but as they keep observing the things, they encounter many fascinating facts like earth and other planets revolve around the sun, our solar system is a part of the galaxy, and our galaxy is not the only galaxy that exists in the whole universe. So they end up on one question, HOW? How it all started? Many astronomers try to prove their theories about the origin but 4 theories make more sense than others.
1.Steady State Universe!
This theory was popular and nearly accepted back in the ’20s. According to this theory, the universe has no beginning and no end, it’s just there from always and remains forever. But as its constantly expanding; however the density (weight) of the universe remains constant.
This theory was proposed by James Jeans in 1920 but it got real fame in 1948 when Fred Hoyle, Thomas Gold, and Hermann Bondi reformulated it. But as new observation and pieces of evidence were taking place, astronomers slowly started to oppose the theory. Like certain features or behavior of the distant galaxies weren’t seen in the nearer galaxies, and this makes sense about the birth of the universe.
This theory is a modern theory and quite an interesting one. Have you watch one of those movies which stories are related to a simulated world like Metrics, Inception, Ready Player One, etc. What if I tell you our whole universe might be a simulation game? Well, this theory is getting a hike due to a recent statement by our beloved Elon Musk the visionary guy. He said in his one interview that we might are be living in a simulation game controlled by higher dimensions. We just don’t feel it because we are programmed to do whatever we are doing right now. As we see the progress graph of video games, we are come from windows XP to virtual reality and augmented reality, these technologies are near to reality. Soon we’ll unable to spot the difference between reality and simulation. So maybe that’s the case with us too. Let us know what you think about it.
3.Big Bang Theory!!
When it comes to the creation of the universe the strongest theory that comes in our mind is The Big Bang Theory because it is widely popular and nearly accepted by everyone as it makes more sense about the origin. Well, this theory was suggested by a Belgian priest named Georges Lemaître in the 1920s. He said the universe began from a single atom which is existed from the very beginning. He called that atom cosmic egg. And from that cosmic egg universe expands to get as huge as it is now. Later in the 1930s, Edvin Hubble observed that other galaxies are moving away from each other which suggests back in time they all were very close to each other. Fun fact, Einstein opposed this theory because he believed that the universe was static, and due to that he introduced the term in his General Relativity Field equation called cosmological constant. This term was trying to prove that the cosmological constant holding a universe in a static state. But as Hubble and Lemaître jointly publish their observations and pieces of evidence regarding the Big Bang, Einstein kinda convinced and removed the cosmological constant from his equation. It was Einstein’s biggest blunder in physics. But as more observations have taken place and found pieces of evidence, this theory got special attention and started to opposing Steady-state theory.
Anyway, the theory suggests that at the very beginning there was nothing but a tiny atom with infinite temperature and density called Singularity, and suddenly it exploded and created the universe we know today. Scientists found out the evidence of the explosion as they detect CMB i.e. Cosmic Microwave Background. CMB is the electromagnetic radiations left from the early stage of the universe, also known as the image of a baby universe. It represents the heat leftover from Big Bang. Even if this theory makes complete sense about the creation but still there are a lot of flaws in this theory. Like it violets the 1st law of thermodynamics which says that matter and energy neither be created nor be destroyed. This law is opposing the big explosion that happened during the Big Bang. This is why this is not widely accepted.
4.Vedic Rashmi Theory
When I first hear about the theory, it got my attention and I became more curious about this theory because it has a background of Vedas. It is a recently introduced theory by Acharya Agnivrat Naishthik. Rashmi means the very first ray of light. This theory gives three causes to the formation of the universe.
- Efficient cause = Anything cannot be created without a creator. The creator is always needed.
- Material cause = Any created thing can never take form without basic materials.
- Normal cause = Any created thing always needs a purpose. Creation cannot occur without purpose.
It is explaining three Gunas (qualities) as a form of creation is mass, force, and motion. But higher science spoken by Lord Krishna in Bhagavad Geeta says,
इन्द्रियाणि पराण्याहुरिन्द्रियेभ्य: परं मन: |
मनसस्तु परा बुद्धिर्यो बुद्धे: परतस्तु स: ||
Meaning = ‘Subtle, they say, are the senses; subtler than the senses is the mind; subtler than the mind is the reason; but subtler even the reason is He (Atman—Supreme force)’
This means the highest thing is beyond all these things and in that state, one can know all the mysteries of the universe.
All the theories we discuss the creation of the universe are just THEORIES! when we practically prove any one of them it’ll become a law of the universe. As Carl Sagan said’ “Somewhere, something incredible is waiting to be known”. Let us know your thoughts on creation.
