宇宙是能量和物质的交响曲，在最大的尺度上演奏。
The universe is a symphony of energy and matter, playing out in the grandest scale.
The work of art is a trace of the invisible.
If you have an apple and I have an apple, and we exchange apples, we both still only have one apple. But if you have an idea and I have an idea, and we exchange ideas, we each now have two ideas.
