EARTH is not perfect sphere.

Our earth is a tri-axial ellipsolid, moving around the sun

in an elliptical orbitat 30km/sec., and rotating its axis at

1666km/hr, which is faster than even the speed of sound.

such hign speed rotation has resulted in the polar areas

being compressed toward the centre and the equatorial

area being bulged out. this explains the earth is not perfect

SPHERE.

NOTHING.....to lose in this WORLD.

IF you can keep your head
when all about you are losing theirs
if you can trust yourself
when all men doubt you
but make allowance for their doubting to
if you can make one heap of all your
winning and risk it on one
turn of pitch-and-toss,
and lose, and start agai at your beginning
if you can dream and not make deams
your master
if you can walk with crouds and
keep your virtue
or walk with kings, nor lose the
common touch
if you can fill the unforgiving minute
with sixty secondsworth f distance run,
your is the earth and everything
that's on it, and-which is more-
YOU WILL BE A MAN।
