The beauty of mathematics lies in its simplicity and depth.

"A leitura é uma viagem sem fim, onde cada página é uma nova descoberta."

善良高尚的人，在贫穷而没有能力去用物质接济别人的情况下，如果遇到别人有迷惑犯傻的地方，能用一句好话来提醒他们；遇到别人有着急和作难的地方，能用一句好话来解救他们，那么他的功业与德行同样是无法计算的。

未来的计算将更加普惠，让每个人都能享受科技的红利。

At a restaurant do you order what you know is great， or do you try something new？ Do you make what you know will sell or try something new？ Do you keep dating new folks or try to commit to someone you already met？ The optimal balance for exploring new things vs exploiting them once found is: 1/3. Spend 1/3 of your time on exploring and 2/3 time on deepening. It is harder to devote time to exploring as you age because it seems unproductive， but aim for 1/3.

The future belongs to those who embrace change and drive it.
