student :what is moment?
prof: moment is a rotational force......wait
                              just see this diagram

in this diagram the person a is 1000newton ant he is at a distance of 1m from the center
 now inorder to be in equlibrium the clockwise moment must be equal to anticlockwise moment... so the guy who is 500newton is at a distance 2m apart...else the guy b will go up
student:why we learn this?
prof:for machiene design such as microscope,bicycle and motorbikes...we need to use calculation...so moment is a terminology used for calculations so as to avoid failure or increase effectiveness of cycles or any vehicle

quality or quantity education

Education is nowadays going so worse than ever.We all know that education is the foundation for development of a country.Education plays a major contribution in todays politics,human evolution,behaviour etc etc.Education is artistic each and every students have their own talents whether it may be sports,acting,cooking,engineering,medicine,teaching etc.But nowadays our Indian politics has made education system so worse such that the students don't think rationally.since majority of Indian population are middle class they become a victim to such an environment.For example in Tamil nadu the literacy percentage is so good but the students from these states doesnt have their own creativity.These students crack a very good score in thier high school studies and they enter engineering or medicine finally they use the same trick to crack their semester and clear their degree with a cgpa of nearly 8.0.Whats the point of getting such good grades and not having a worth knowledge?.This has been shown in many films such as "3 idiots".let me ask you a very simple question? steve jobs,mark zuckerberg,bill gates....iam sure you all know these names.They are all dropout students without an engineering degree.Is there any succesful drop out in tamil nadu?you all might heard of the news a principal killed by 3 students in tuticorin,delhi gang rape.Just see whats the main cause for all these? the answer is movies..nowadays we dont respect and watch artistic,conceptual movies...we all love to see commercial movies these films are low budget films that finally score a block buster hit...finally what happen to those directors who took realistic?.We all make a single person the dominant actor.It;s not because of his talent but because of the exposure.we fail to realise the conclusion or message of any films taken with good script and high budget.

teachers,directorss,politicians all play a vital role in the development of a country unfortunately even teachers too fail to understand their responsibility for the development of human race.in tamilnadu there are nearly 550 engineering colleges whereas 20 medical colleges .whats the reason ? answer me...why are the clasrooms filled by students who dont ask doubts or with teachers who dont inspire them...???????????
