Why does Apple logo presents apple get bitten?
 
Not so long ago, reading about Alan Turing, I drew attention to a monument depicting him as holding an apple – this is the encrypted information “Turing – the creator of computer science”. Intuitively, immediately my thought turned to the Apple logo representing the same fruit but bitten .. is the case that Apple use the apple symbol there? there are many different theories … one of them says that it was tribute devoted to the father of computer science – Alan Turing (mathematican, codebreaker and father of computer science)..
