Most Amazing Concepts in Physics

By: Nikhil Malankar


Science deals with many aspects of our daily life. You start your day with the application of Science. Just take an example of the toothpaste you are using or the motion of a wave or even respiration. Everything relates directly or indirectly with Science. Science can be divided in the following parts.

  1. Physics
  2. Chemistry
  3. Math
  4. Biology

From the topic you must have understood that I am going to talk about Physics. OK Then, What concept do you find the most amazing? If you don’t find it on this list then you are welcome to say about it in the comments column. Let me start off with the list.

1. E=mc^2

We all know about this formula. It was introduced by one of the greatest scientists of all time .i.e. Mr. Albert Einstein. This concept is really interesting one and the debate about its correctness is still going on. It gave rise to other concepts like warped space and space time which are also very interesting and deep. It is a very controversial topic and I had also written an article related to this one. The link to it is:


The most important concept given by Physics to mankind is the Gravity concept without which it would have been impossible to make rockets and other studies related to it. The most famous example to explain gravity was given by Sir Isaac Newton with his Apple Tree example. It is said that Newton was not the first one to observe the phenomenon of gravity but it was Galileo who first discovered it. Anyways, this concept caused a revolution and modern day physics is heavily dependent on this concept.


3. Space Travel

Few centuries ago it was impossible for mankind to think of such a concept. At that time we would have also not thought of travelling through Airplane but in today’s time everything is possible. Space Travel is a wonderful concept which has given rise to the discoveries of our solar system. Now it is also possible for humans to send computers in space to study our universe. Landing on the moon was possible due to this. It was history created and a new step made by man. So, Space Travel is also an amazing concept turned reality in Physics.


4. Time Travel

This has not yet turned into reality but I think that in the near future it will be possible to travel through time too. Many scientists think that time travel will make humans lazy or will cause some disturbance but one thing is sure that time travel will be possible and no one can stop such a great concept to turn into reality. Stephen Hawking also has given so many concepts related to time travel. You can read his book ‘A Brief History of Time’ or even watch his ‘Into The Universe’ which frequently comes on Discovery Channel.


5. The Black Hole

I think this is one of the most wonderful concepts in Physics. It is a perfect example of a Perfectly Black Body. The compression caused creates a high gravitational field around the dead star so that light also cannot escape from it. Light has a tremendous speed of 3 X 10^8 m/s and if it can’t escape from a black hole then imagine about the power it has! I personally think that light is not the fastest. I have thought over it for quite a while now and I think I am right about my previous statement. Using the concept of black hole it is possible to time travel but only in the future. So, Black hole is also an amazing concept.

These are 5 of my favorite and amazing concepts in Physics. Do you have anything more to share?

The Universe according to Me

:Posted by Gaurav

All the theoretical physicists around the world are looking for the Grand Unification Theory. A theory that incorporates everything in the universe including the universe itself. The four forces in nature are all that make up this universe or rather I should say that universe which can be observed. Definitely we haven’t seen the edge. Neither we have found any center. On the other hand our universe is so big that by laws of mathematics, which we have devised, we are at the center.

Thus all the theories and the calculations we have done cannot be imposed on that part of the universe that we haven’t observed. We may ourselves be an exceptional part in the universe where the value of Planck’s constant is what it is. This is pure imagination but, according to quantum physics, a valid one. The constant will have multiple Eigen value states until and unless it is actually observed. So there is always a possibility that we would not be able to imagine what is beyond the observable boundaries like the experiment with Schrodinger’s cat.

So here’s, what I should say, an extended version of what you all know.

The Universe according to me is designed in three basic simple steps. These are :

1) Initiation

2) Chaos

3) Re-Order

Everything that we see is a result of some kind of initiation. This may be somewhat opposite thought to those who believe in coincidences. But actually, if observed carefully, coincidences are merely the happening of two or more events simultaneously. It is the nature of human mind to find the relation between two events that it observes simultaneously.

Consider a small accident happening. A car hits a truck and loses its rear view mirror. Obviously, the two drivers first come out to check the damage, if any done, to their respective vehicles. The car driver sees that he has lost a rear view mirror and starts yelling at the truck driver. The truck driver doesn’t thinks that it was his mistake. The observers around see the broken mirror and start creating their views about the accident. Each of them has a different theory. Some would say that the truck should have stopped because there was traffic. Some would say the car was speeding and they thank God that no one is hurt. Some would say the car driver is drunk and that’s why he is wasting his time and energy for such a small damage what could have been a big one. Some would say it was just a coincidence.

There can be a correct theory. But the coincidence is that the car and the truck came in contact with each other. So the observers make their theories and name them as coincidences. For eg. An observer who observed the car before collision would say that the car driver is to blame that he was speeding. It was a coincidence that the truck took the car’s rear view mirror.

Hence, everything has an initiation, we just name it coincidence.

Then comes Chaos.

The world has been chaotic in some or the other point in time. Consider the above example again. The car hits the truck. So everything around it changes. If the car had not hit the truck, everyone would continue their work as planned. The truck would have safely crossed a road. The drivers would not have got out of their vehicles. All the observing people would not be observers at all. Of course I am taking the collision as the initiation. The initiation was followed by the chaos by the immediately above assumptions not happening. Everyone came out of the order they were meant to remain in.

And then comes Re-Order.

In the same example, eventually everyone has to go to work or home or any place they want to. So they move away from the site of accident. The two drivers take their vehicles out of the way due to honking of oncoming traffic and the road becomes busy again. But here the order is created due to initiation of some other kind(like the honking).

Hence if observed carefully, everything in the world has an initiation and then go into chaos and then reorder. This was also happening at the time the ‘ Time ‘ started. And it is happening to this very day. The chaos and the reorder become the initiation of other processes thus making the nested cycle of themselves.
