Mathematics is not a spectator sport.

The balance of marine ecosystems is our shared responsibility. Destroying it means destroying our own future.

The time which we have at our disposal every day is elastic; the passions that we feel expand it, those that we inspire contract it; and habit fills up what remains.

即使在困难时刻，我也总是努力保持积极。
