明月幾時有？
把酒問青天。
不知天上宮闕，
今夕是何年？

.

我欲乘風歸去，
唯恐瓊樓玉宇，
高處不勝寒。
起舞弄清影，
何似在人間！
轉朱閣，
低綺戶，
照無眠。
不應有恨，
何事長向別時圓？

.

人有悲歡離合，
月有陰晴圓缺，
此事古難全。
但願人長久，
千里共嬋娟。

New Year Eve 2007,

Many of the Walter Lewin Lectures on Physics at MIT have been shown for over six years on UWTV in Seattle, reaching an audience of about four million people. Lewin personally responded to hundreds of e-mail requests that he received per year from UWTV viewers. For fifteen years he was on MIT Cable TV, with programs aired 24 hours per day helping freshmen with their weekly homework assignments. Lewin also teaches video courses on Newtonian Mechanics, Electricity and Magnetism, and Vibrations and Waves, which can be viewed from the MIT OpenCourseWare web site. His MIT lectures for science teachers and for middle school students can be viewed on MIT World.

It’s impossible to learn very much by simply sitting in a lecture, or even by simply doing problems that are assigned.

…

I think, however, that there isn’t any solution to this problem of education other than to realize that the best teaching can be done only when there is a direct individual relationship between a student and a good teacher — a situation in which the student discusses the ideas, thinks about the things, and talks about the things.

When I was 17, I read a quote that went something like: “If you live each day as if it was your last, someday you’ll most certainly be right.” It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: “If today were the last day of my life, would I want to do what I am about to do today?” And whenever the answer has been “No” for too many days in a row, I know I need to change something.

— Steven Jobs:

Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure – these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.
