Are You Alone In Planet Earth

Yes we are alone in planet Earth . As for as the  present day scientific findings it is established that we are alone in planet Earth.There is no even traces of living things in other planets of  the solar system so to say ,Moon,.Mars Mercury,Jupiter,Venus,Saturn,Uranus,Neptune and Pluto.There is also no reply for our  radio or other signals from any other celestial objects.Therefore it is presumed that we are alone in planet Earth.It is quiet disappointing.Is it so!

Gold,Silver And Diamond

Glittering gold shining silver and sparkling diamond.what is the scientific reason behind this.All that glitters are not  gold is a proverb that says the glittering nature of gold from time immemorial.The glittering nature of gold is linked to its atomic status.Gold has a total electronically saturated status in its atomic form.Therefore it has no tendency to combine with anything it comes in to contact.Because of this the surrounding atmospheric air or water or other materials that may come in to contact with gold can do no harm to gold.Generally all metals are shiny in nature like gold.But what is the difference is all other metals except gold combine with oxygen that is present in the atmospheric air and form their corresponding oxides which are not shiny,.but gold remains as gold always and it glitters for ever.
                                            Silver assumes more or less the same nature in its atomic state like gold but to a lower extend and hence it is shiny to lesser period of time and it gets shining back when it is polished.                                                          Diamond is sparkling because it has the highest total internal reflection and has the highest refractive index of all the materials available in nature.You may wonder that diamond is nothing but carbon in its allotropic form.

Matter and Energy

Matter is something which occupies space,Energy is something which do work.Matter can neither be created nor destroyed but can be changed from one form to other without loss or gain. Like mater energy also can neither be created nor destroyed but can be changed from one form to other without loss or gain.You can not make anything out of nothing and also you can not do anything to nothing!

vehicles without wheels







Can you imagine any vehicle without wheels! Is there any vehicle without wheels.Yes there are vehicles without wheels .They are Hovercrafts,Bullet trains in Japan Sledges in snowy hills and so on.The Hovercrafts are latest vehicles that can travel in land as well as over water.They use air beds from beneath the vehicle instead of wheels and have propellers in front to move forward. The bullet trains use magnetic suspension bed instead of wheels.

Aeroplane and Rocket


Airplane needs air to travel where a Rocket does not. this is because airplane utilizes air as a medium to travel where a Rocket uses the Newton^s third law of motion that stipulates that every action has equal but opposite reaction.You can watch while Rockets traveling  there comes a jet of fire coming out forcibly from behind the rocket which as per Newton^s third law of motion pushes rocket forcibly forward .that is why rockets are meant for outer space travel where there is no Atmosphere.

Thiruvalluvar and Thirukkural

There are 1330 kurals are written by Thiruvalluvar. each kural consists of less than two lines.Each kural either teach how a particular problem can be solved that we face in our life in a particular situation or it itself raise a problem and gives a correct solution for it.what is quiet amazing me is how a single person deals so to say so many problems that different men may face in different situations in  their entire life time and gives correct solution and by adhering it the one who follow thirukkral can lead a successful and happy life.
