I do not know an instance of a major mathematical advance initiated by a man past fifty
Interpretation
The quote suggests that significant breakthroughs in mathematics are rare among those over fifty years of age.
G. H. Hardy's quote highlights the perception that major mathematical advancements are commonly associated with younger individuals. It brings attention to the idea that creativity and inspiration in mathematics might diminish with age, questioning whether the passion and drive needed for monumental discoveries fade over time.
In practice
In a lecture about mathematical innovations, this quote could be used to emphasize the importance of youthful perspectives.
A chess problem is genuine mathematics, but it is in some way "trivial" mathematics. However, ingenious and intricate, however original and surprising the moves, there is something essential lacking. Chess problems are unimportant. The best mathematics is serious as well as beautiful-"important" if you like, but the word is very ambiguous, and "serious" expresses what I mean much better.
Mathematics is not a contemplative but a creative subject; no one can draw much consolation from it when he has lost the power or the desire to create; and that is apt to happen to a mathematician rather soon. It is a pity, but in that case he does not matter a great deal anyhow, and it would be silly to bother about him.
Exposition, criticism, appreciation, is work for second-rate minds.
It is hardly possible to maintain seriously that the evil done by science is not altogether outweighed by the good. For example, if ten million lives were lost in every war, the net effect of science would still have been to increase the average length of life.
Real mathematics must be justified as art if it can be justified at all.
If intellectual curiosity, professional pride, and ambition are the dominant incentives to research, then assuredly no one has a fairer chance of gratifying them than a mathematician.
When you combine the ability to express your unique talent with service to humanity, then you make full use of The Law of Dharma.
Do good with what thou hast, or it will do thee no good.
We are more heavily invested in the theories of failure than we are in the theories of success.
So many people would like to have guidance from God because obviously, if you have a word from God, it's the best possible thing. But they don't relate that to life as a whole. Often they want guidance as a way of opting out of the responsibility of making decisions.
Fill what is empty, empty what is full, and scratch where it itches.
You have been compelled to cultivate your reflective faculties, for want of occasions for frittering your life away in silly trifles.
