Alas! So abundant are mediocrities that one who surpasses them by a grain appears to us as a genius.
Forwarded from 0/0 (Haidar A. Fahad)
The question of whether someone is a genius or not is simply an argument by the populace as to whether this individual should be deified and deserves his own place in the pantheon of their collective imagination & fantasy. Genius is, by large, a social status.

Clarke's three laws

Perhaps the adjective โ€˜elderlyโ€™ requires definition. In physics, mathematics and astronautics it means over thirty; in the other disciplines, senile decay is sometimes postponed to the forties.

There are, of course, glorious exceptions; but as every researcher just out of college knows, scientists of over fifty are good for nothing but board meetings, and should at all costs be kept out of the laboratory.
Too much imagination is much rarer than too little; when it occurs, it usually involves its unfortunate possessor in frustration and failure โ€“ unless he is sensible enough merely to write about his ideas, and not to attempt their realization. In the first category we find all the science-fiction authors, historians of the future, creators of Utopias โ€“ and the two Bacons, Roger and Francis.

The lesson to be learned from these examples is one that can never be repeated too often, and is one that is seldom understood by laymen โ€“ who have an almost superstitious awe of mathematics. But mathematics is only a tool, though an immensely powerful one. No equations, however impressive and complex, can arrive at the truth if the initial assumptions are incorrect.
