... Why is the muon, some dumb particle, 200 times heavier than the electron? Why is the proton about 2,000 times heavier than the electron? Why is the electric charge of the electron what it is? Why are there six quarks in nature? Why not seven or eleven or five? There are many, many "why" questions. Also a number of 'how' questions. What is the mechanism that causes the weak interactions to be weak and the electromagnetic interactions not weak?

Economic progress means the discovery and application of better ways of doing things to satisfy our wants. The piping of water to a household that previously dragged it from a well, the growing of two blades of grass where one grew before, the development of a power loom that enables one man to weave ten times as much as he could before, the use of steam power and electric power instead of horse or human power - all these things clearly represent economic progress.
Kenneth Boulding
Elegance requires that the number of defining equations be small. Five is better than ten, and one is better than five. On this score, one might facetiously say that String Theory is the ultimate epitome of elegance. With all the years that String Theory has been studied, no one has found even a single defining equation! The number at present count is zero. We know neither what the fundamental equations of the theory are nor even if it has any.
Leonard Susskind
Siphonophores do not convey the message-a favorite theme of unthinking romanticism-that nature is but one gigantic whole, all its parts intimately connected and interacting in some higher, ineffable harmony. Nature revels in boundaries and distinctions; we inhabit a universe of structure. But since our universe of structure has evolved historically, it must present us with fuzzy boundaries, where one kind of thing grades into another.
Stephen Jay Gould
But to everything in this world there comes an end; there even comes an end to the torments suffered in those intermediate states of transition when the last secret tear of one's soul is bitterly swallowed, and the crisis passes, resolving itself into some new sort of phase, which even as it comes into existence is fated in turn to pass away, to disappear in the eternal changing of the times and seasons.
Nikolai Bukharin
The weed crushed and pressed by the heavy rock may slowly and gently grow up anew helped by the fresh air, sunshine, and sympathetic rain. On the other hand, the rock is often broken through exposure to nature and weathering. Life is a strong power to grow in tenderness; this fact may be considered as having a close relation with human life. At the same time tenderness has sometimes stronger power against stiffness or hardening due to extreme strain.
