In physical science the first essential step in the
direction of learning any subject is to find principles
of numerical reckoning and practicable methods for
measuring some quality connected with it. I often say
that when you can measure what you are speaking
about, and express it in numbers, you know something
about it; but when you cannot measure it, when
you cannot express it in numbers, your knowledge is
of a meager and unsatisfactory kind; it may be the
beginning of knowledge, but you have scarcely in your
thoughts advanced to the state of Science, whatever the
matter may be.
When you cry for missing the sun, you will miss the stars again.

Love is imagination. The other is the carrier. It's you who give the meaning to it.

Give it your best shot every time.
每一次都要拼尽全力。

Everything has cracks and that's where the light comes in.

Talent indeed makes a person shine, but hard work does too.

What we do in life echoes in eternity.
今生所为终有回响。
Thank you for appearing in my youth.
