2Physics Quote:
"Eckhard D. Falkenberg, who found evidence of an annual oscillation in the beta-decay rate of tritium, was either the first or one of the first to propose that some beta-decay rates may be variable. He suggested that the beta-decay process may be influenced by neutrinos, and attributed the annual variation to the varying Earth-Sun distance that leads to a corresponding variation in the flux of solar neutrinos as detected on Earth. Supporting evidence for the variability of beta-decay rates could be found in the results of an experiment carried out at the Brookhaven National Laboratory."

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 ....
