2Physics Quote:
"Today’s most precise time measurements are performed with optical atomic clocks, which achieve a precision of about 10-18, corresponding to 1 second uncertainty in more than 15 billion years, a time span which is longer than the age of the universe... Despite such stunning precision, these clocks could be outperformed by a different type of clock, the so called “nuclear clock”... The expected factor of improvement in precision of such a new type of clock has been estimated to be up to 100, in this way pushing the ability of time measurement to the next level."

1905: The most productive year of Einstein

In 1905 Einstein gave the world three exciting ideas in 3 separate papers:

(i) The application of the concept that light also behaves like a particle
even though many of its behaviour are more like waves.
Einstein later got Nobel Prize for this paper which explained the
photoelectric effect.
The photoelectric effect is something that converts light into electricity
and works in photocells.
You know what photocells are! Nowadays in most public toilets
it automatically switches on flushes as you leave!

(ii) The brownian motion - the kind of motion of you see among dust
particles if you throw some in a glass of water. The statistics of this
motion is very interesting to Physicists and its knowledge is applied
in understanding so many other things - FROM the transfer of heat
among bodies TO how stars got formed in the first place!

(iii) The Theory of Relativity: Who have not heard of it?
This is the paper which revolutionized mankind's concept of time
and space in which they lived.
Einstein showed us that time was no more an absolute concept.
Your time could be different from my time if we move to or from
each other at constant speed.
These concepts gave us the most well-known scientific equation:
E = mc^2 and taught us that mass can be converted into energy.

We will elaborate on these concepts more. ... one by one ...
We will discuss about what else Einstein did and Others also followed.
How were experiments done to prove Einstein's concepts?

This is just an introduction. So many more stories to tell ....

Wait and check us regularly ....
