WHY GOLDEN RATIO IS RELATED TO PHOTOGRAPHY  What is golden ratio? - In   mathematics , two quantities are in the   golden ratio   if their   ratio   is the same as the ratio of their   sum   to the larger of the two quantities. The figure on the right illustrates the geometric relationship. Expressed algebraically, for quantities   a   and   b   with   a  >  b  > 0, {\displaystyle {\frac {a+b}{a}}={\frac {a}{b}}\ {\stackrel {\text{def}}{=}}\ \varphi ,} where the Greek letter phi ( {\displaystyle \varphi }  or  {\displaystyle \phi } ) represents the golden ratio. It is an irrational number with a value of: {\displaystyle \varphi ={\frac {1+{\sqrt {5}}}{2}}=1.6180339887\ldots .} The golden ratio is also called the  golden mean  or  golden section. (source:wikipedia) -you can trace the curve of this golden ratio by making squares using fibonacci sequence{0,1,1,2,3,5,8,13,21,.....}.It is sum of previous numbers,{[0],[1],[0+1=1],[1+1=2],[1+2=3],...}.

Why Keyboard Is Not Arranged Alphabetically!!! Yes it is weird that why keys in keyboard is not set as alphabetically. What is reason behind  that ever thought about that, don't give pressure to your mind. We give you reason behind that. Originally, the typewriters of the 1870.

Firstly, characters were mounted on metal arms or  type-bar s, which would clash and jam if neighboring arms were pressed at the same time or in rapid succession. Secondly, its printing point was located beneath the paper carriage, invisible to the operator, a so-called "up-stroke" design. Consequently, jams were especially serious, because the typist could only discover the mishap by raising the carriage to inspect what he had typed. So placing character like in alphabetical manner (B-C ,J-K..) helps typis
