TEASER - 17

WHOSE SIDE IS IT ANY WAY

Every  object  such  as,  cars,  houses,  dogs,  humans,  planes, books, watches or TVs, have their own right, left, front and back sides.

When we refer left or right side of a book or a watch or a TV or a road, we refer left  or right  side in same way as it would be in case of a car or a plane or a dog or a human?

Similarly when we say clockwise or anticlockwise we refer to it from watch’s own side?

(a) Falls

(b) True

THE EXPLANATION:

When  humans  are  driving  cars,  both  car  and  driver  face  in  same direction, hence left hand side of driver is also left hand side of the car.

CARS AND HUMANS FACE SAME DIRECTION  WHEN DRIVING HENCE BOTH HAVE SAME SENSE OF RIGHT AND LEFT

When a woman looks into a mirror everything gets reversed. Her left hand  becomes  right  hand  of  her  image  in  mirror  because  both  of them are facing each other and the image behaves as if she is an another person looking at her.

RIGHT IS LEFT (AND VICE VERSA) WHEN LOOKING INTO MIRROR

However,  when  a  man  is  reading  a  book,  even  though  both  book and man are facing each other in same way as he would be facing his image in the mirror, the left and right side of book does not get reversed.

The left side of the man (reader) is also the left side of book and his right side is the right side of the book. Book itself does not have its own left or right side. Had it been so our right would have been left side of the book.

RIGHT IS RIGHT (NOT LEFT) WHEN REFERRING TO BOOKS

Similarly  when  we  are  facing  a  watch  and  referring  to  a  direction called  ‘clockwise’  or  anticlockwise’  movement,  we  are  explicitly referring to the direction from viewer / user point of view.

The circularity of clockwise movement would be from top to right, (in same  way  as  car’s  steering  is  moved  when  turning  to  right).  The opposite    sense    of    rotation    would    be    ‘counterclockwise’    or ‘anticlockwise’.

CLOCKWISE MOVEMENT (GENERALLY LEFT TO RIGHT)

Assume  that  a  watch  has  grown  its  own  hands  and  legs  and  is behaving   like   a   human   being.  What   would   be   the   ‘clockwise’ movement ?

img119.png

WHAT IF CLOCKS HAD HANDS & LEGS AS WE HAVE (CLOCKWISE MOVEMENT WOULD BE REVERESED)

Clockwise movement would be, from TOP to LEFT (in same way as car’s steering is moved when turning to left) and not TOP to RIGHT as   is   normally   considered.   (Anticlockwise   movement   would   be opposite to that):

In strictest sense, the “clockwise” movement is a misnomer because we never consider watch having left / right side like us, but we refer it from  our  own  point  of  view.  Hence  it  can  be  called  ‘viewer-wise clock-movement”. The left or right side of an object is dependant on whether they face in same direction or opposite direction as that of humans (user) while in use.

User centric world view:

1.   As the reader and the book or the TV or the photograph or the  watch  always  face  each  other  when  in  use,  there  was perhaps  no  need  to  assign  left  or  side  to  them  but  was always referred from user’s point of view. On the other hand, cars, buildings, trains, animals etc face in same direction as humans while in use, they have left and right side similar to humans.

2.   All man made materials or even natural ones are referenced from user (humans) point of view because we are the ones who   use   them   and   we   are   the   ones   who   require communication  in  such  languages  which  fundamentally  is based   on   naming   of   each   and   every   possible   aspect perceived by humans.
