Corpus Clock

A friend of mine shared a link with me.

I really enjoyed collecting the Gyan from video.
And I did some googling on it and thought would just share the findings with you.
Wiki explained more about the corpus clock, they went more into the technicalities of how it is made.

Its amazing to read that around 200 people were involved in the project and the amount of money that went into it.
As explained in the video the corpus clock is based on the Grasshopper Escapement invented by John Harrison.
The following link explains the beauty of Grasshopper Escapement.

The best part is it was all Mechanical and it did not require any lubricant.

But the thing is, its still not accurate for eternity. Even corpus clock is told to be accurate only for 200 years.
So is there something that is more accurate?
Around a year back I had seen a documentary which talked about Albert Einstein vision of an Atomic Clock which would be much more accurate.
I thought that such a clock is not in existence, but Google(The tech God) proved me wrong.

The following link talks about the Atomic Clock.

And this link talks about its practical usage.

In fact if you are a GPS user you have used a Atomic Clock.

Accuracy of atomic clock: "The best ones on Earth lose no more than one second in millions of years"

Well some internet backbone servers are linked to GPS for time accuracy and I am an Internet user, so that make me also a user of Atomic clock... Wow... ;)

Thanks to Albert Einstein.

Thank you all for bearing me...

Levitation at its best - enjoy science

Today I got a forwarded mail which had a video showing levitation using magnets.
I video was incredible to see.
Did some googling on it and found this link which explains the same video and how the different elements play thier role.
The way nitrogen behaves in a magnetic field was interesting to read.
It about inhomogeneities

I sometimes seriously think about going back to school and performing such experiment... but this time with the right attitude and spirit
