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:

2.Gravity

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?

My views on the Universe : Part 3

This article is the 3rd part of the series ‘My views on the Universe’. The first part was.  My Views on the Universe : Part One and the second was My Views on The Universe : Part Two. So, I recommend you to first read the 1st part and 2nd part and then come to this 3rd part. Let me introduce you again to this series. This series is my imagination about how the universe actually is. So, without wasting much time let me start off with the topic.

This 3rd article is based on an assumption that the Universe is just a sheet of paper. Paper? How? Okay! Let me express myself. Read on.

Imagine that the Universe is just a paper. Paper has many uses and mostly it is used for writing and drawing. So, imagine that the Universe is sketched on a piece of paper. All the planets, meteoroids, stars, etc. are just drawings! This piece of paper is not too big but is very detailed. It has been sketched using a very fine pencil. Or should I say a rainbow pencil which adds a mixture of all the beautiful seven colors and their shades into this Universe. So, why does the Universe appear to be black? The answer is because most of the part is not colored yet J. It takes a lot of time to detail everything and so the artist of our Universe has decided to give colors only to the part which are important. The specialty of His art is that this paper turns its drawings to life within itself! And that’s why we have various life forms. But only those life forms exist which the artist has written at the back of the paper.

So, there is a 100% possibility that aliens exist. This artist has created only our Universe. There are many other artists who have sketched their imagination into their papers and created many Universes which can also be termed as parallel universes. One more thing is that this artist is never satisfied with is work and so he is always creating a new imagination and adding it to our Universe. So, our Universe is ever expanding.

We should praise the intellect of this artist who has created such a wonderful world! And we can learn an important lesson from his artist that ‘Never be satisfied! Satisfaction leads to rest and rest will never fetch you rewards’. So, keep on working and adding new feathers to your hat. And one day you will have your world as the Universe itself!

So, this was my 3rd part. Hope you liked it. In case you did not read my first 2 parts then their links are:
