HOW DID I COME ACROSS THAT QUESTION?

Many a Scientist Claims to Feel a Keen
Sense of Beauty in Scientific Theories:

“It is more important to have beauty in one’s equations than to have
them fit experiment … because the discrepancy may be due to minor
features that are not properly taken into account and that will get cleared
up with further developments of the theory …It seems that if one is working
from the point of view of getting beauty in one’s equations, and if one
has really a sound insight, one is on a sure line of progress.”

P.A.M. Dirac

And again:

“As a mathematician, I am especially concerned with inspirational and original
thought in others who are mathematicians, but I imagine that there is a great
deal in common between mathematics and the other sciences and arts.”

Roger Penrose

“… it is clear that no significant discovery or invention can take place without
the will of finding. But with Poincaré, we see something else, the intervention
of the sense of beauty playing its part as an indispensable means of finding.
We have reached the double conclusion: that invention is choice; that
this choice is imperatively governed by the sense of scientific beauty.”
