Why do ENGINEERING students always
prefer Local Author books than
REFERENCE books..??
The local author says- "Jack & Jill went
up the hill to fetch a pail of water, jack
fell down and broke his crown and Jill
came tumbling after"
& REFERENCE BOOK says,
“ 2 humans ascended a certain
geological protuberance to collect
hydride of oxygen whose quantity is
not specified.
One member Jack of rapid irregular
disturbing movements encounter fatal
logical gravitational error leading to
complete disarray!
Other member whose scope lies within
disarray descends down the
geographical
protuberance at an acceleration,
whose magnitude is controlled by the
force of gravity"! :P :D
