我开始相信，一位伟大的教师是一位伟大的艺术家，而且像其他伟大的艺术家一样稀少。教学甚至可能是最伟大的艺术，因为媒介是人的思想和精神。
"I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit."
心的沉默是最响亮的呼喊。
The most enduring changes come from understanding the root causes of problems, not just their symptoms.
"A child who reads will always have a friend."
"The best way to predict the future is to create it."
发现可能性的极限的唯一方法就是超越它们进入不可能。
"We need to think of software not just as code, but as a mathematical object that can be analyzed and verified."
