As some one who  has  lived  my  SCHOOL&COLLEGE DAYS  without  knowing or using  a  compter, intenet or  TV channel  or  mobile phones or iwhtout a  fax machine or  an electronic  typre-writer,  I am amazed  how  adances in  technology, computer, information  technology, media  etc  have  transformed world  as a  whole as  an entirely  new magical world!  One was  compelled  to  read  books  to  gain knowledge or information  on any thing  of  interest  for studies  or  research  or  any subject  of interest   and one  was compelled to  travel  to far off  places to access new information or  knowledge  or even to  write an essay  as  part of  school or  college  curriculum  and librareies whether in the  village or  colleges  were  the knowledge providers  for students  & scientists & researchers  alike!  I  am  feeling jealous how  internet , google, microsoft  and  e-books  or podcasts  are   Helping millions& millions of truth seekers & researchers & humans all over the  world l  in the search for truth whether for general knowledge, for increasing the potential of one's brain and for education as a whole! I remember the days when I spent 3-4 years in University of Paris, France, making tours of all science labraries in Paris to look for refrences & details of many scientific publications of researchers & scientists while doing master Thesis "Diplome d'etudes approfonies) & for doing my Doctoral Thesis etc & doing the tours to libraries many times a week for more than 3 years & FEEL jealous that doctoral & master research students are able to access those scientific & research data so easily using internet, google, microsoft application by touch of a button on a computer or a mobile phone! Simply Awesome that past 50 years has been the most revolutionary & knowledge enhancing period of perhaps of the past 25000 Years ! Yes  technologic  advances  of  the past 50  years  perhaps  has  transformed  the  world  & these  50  years  must rank  as  the most  impressive  of the past  25000  Years & more  too
