2Physics Quote:
"Many of the molecules found by ROSINA DFMS in the coma of comet 67P are compatible with the idea that comets delivered key molecules for prebiotic chemistry throughout the solar system and in particular to the early Earth increasing drastically the concentration of life-related chemicals by impact on a closed water body. The fact that glycine was most probably formed on dust grains in the presolar stage also makes these molecules somehow universal, which means that what happened in the solar system could probably happen elsewhere in the Universe."

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 ....
