Interested about the picture? Autonomous experimental design allows us to answer the question of where to take the measurements. More about it is here...

Albert Einstein: The Foundation of the General Theory of Relativity

This evening I was wondering how our brain can comprehend this complex universe under the mathematical and philosophical way. These scientific methods involve people being able to speculate and hence learn on the basis of mistakes made by others. Thats why communication is so so important: you do not end up re-inventing the wheel!

I did some nice and extensive study of General Theory of Relativity (GTR) when I was Master's student in Tribhuvan University in Nepal. Today, after finding the Original Manuscript by Einstein on Relativity, I was equally amazed on its simplicity and compactness.
This is an awesome paper: No doubt!
In the paper, he starts from very basic formulation of the theory and justifies his theory with compelling examples. WOW!!!
Of course, you will need some background of mathematics but it is real fun.
The paper which revealed the fact that "matter tells space how to bend; space tells matter how to move" can be found here ...

If you are further interested, you can contact Prof. UdayRaj Khanal in Tribhuvan University. (He was my Thesis supervisor in M.Sc., Physics)

First Ever Impressive Scientific Dream

It is 544AM now, I was just Dreaming something strange.

I was reading a Physics News in Paper(that was not online!). The news was highlighted with light blue/green background and was presented in a table in the bottom-right part of the right sheet.

It read something like:
"A team of scientist studying Aurora has come across a strange effect....
One of the team member has gained a super natural effect ...
(I have now forgotten another line in here... may be you can read it sometimes in future: ha ha)
He can now see a kilometer depth inside the sea and is being employed for fishing industry"(heh, fishing industry???)

This is completely ridiculous. I mean, I don't know what triggered this dream. May be the trailor of Steven Spielberg's upcoming movie/series (?) which I was watching on TV or the advertisement of supernatural series or the Thriller that I was watching while having dinner...

This is my dream

Give me enough time, I will impress you!

While I am feeling that I have little bit of spare time, I do watch the TED presentations. They are great!!!

One of the video I recently watched has impressed me. It is about the creation of universe and the on-going experiment to reveal the secrets of Nature.
The take home point was: If Hydrogen is given 14 billion years, it can create such a magnificent Universe.
I turned into myself and asked, wow!

Give me some time, I am sure that I will impress you!!!
Enjoy the presentation.

Large Hardon Collider Rap

This is fun .
Besides being funny, it is peculiarly educative.


Try to follow the details. It is amazing.
I liked it!

Mind your concentration

This is amazing trick!



Does mind trick us?
Or do we trick ourselves?

In this video, viewers are asked to see how many times the ball was passed by the guys with white shirt.
If one goes for accuracy and forgets everythings else...

Watch the video.
