nice article..whoever has written it originally and whoever is now rewriting it. the original writer forgot that the research work done at study level has nothing to do in real life. its just a foundation. actual research people do in their career later. tomorrow this intelligent person will suggest for all to go to 1st standard because it should expire..isnt it ph.d. filters all people who are not suitable for this type of work. it improves a persons capability to analyse a problem and derive conclusion from it. and for their kind information...most of the findings done by people who has done their phd 20-30 years ago... their research work is their study all their life where they learn all the time.
