The following is from Wikipedia
A genius is a person of great intelligence, who shows an exceptional natural capacity of intellect, especially as shown in creative and original work. Geniuses always show strong individuality and imagination, and are not only intelligent, but unique and innovative.
Although the term "genius" is sometimes used to denote the possession of a superior talent in any field, e.g., Roger Federer may be said to have a genius for tennis or Winston Churchill for statesmanship, in many of these cases the term is applied incorrectly and should instead be used specifically to denote an exceptional natural capacity of intellect and creative originality in areas of art, literature, music, science and mathematics.
So - do you agree that the term genius should only apply to people in the areas stated or can it apply to other areas. If it's the later, who would you nominate
