没有铅笔和纸?
There are no esoteric formulas or secret states of mind that produce good designs effortlessly and designs are not created by only moving a pencil around on a piece of paper.
没有任何奥妙的公式或神秘的心境可毫不费力地提出好的设计方案。而设计方案决不是只用铅笔在纸上画画就可提出来的。
Baez said. "No expensive equipment, just pencil and paper, and you can start fiddling around with patterns and numbers."
不需要昂贵的设备,只需要纸和笔,你就可以在各种模型与数字之中摸索。
