sics and Eastern philosophy:
"If you meet the Buddha on the road, kill him." - Lin Chi, c. 850 CE
"Wisdom cannot be passed on. Knowledge can be conveyed, but not wisdom" - Siddhartha (Hermann Hesse)
"You should do the work yourself, for Buddhas only teach the way." - Buddha

... we have no direct intuition about the equality of two time intervals. People who believe they have this intuition are the dupes of an illusion .... It is difficult to separate the qualitative problems of simultaneity from the quantitative problem of the measurement of time; either one uses a chronometer, or one takes into account a transmission velocity such as the one of light, since one cannot measure such a velocity without measuring a time.
- Henri Poincaré.


Physics is consistent mathematical models that describe the world.

Listening to lectures is not enough.  All processes of learning are somehow connected to active participation, and the learning of physics is no exception.  Therefore, it is imperative that you work diligently at your own desk.  However, this does not mean that you should only work alone.  I encourage you to form study groups and collaborate with your classmates.

Relevant Quotes


The thinking of a scientist differs from that of a student.  The student wants to know facts: numbers, dates, results, things which might appear on the final exam.  How old is the universe? How distant is the Moon? How hot is the Sun's visible face? All these can be dug out of textbooks and encyclopedias, but they alone tell next to nothing about the science.  A scientist instead asks, What is the evidence?

- David Stern


Problems are the cutting edge that distinguishes between success and failure. Problems call forth our courage and our wisdom; indeed, they create our courage and our wisdom. It is only because of our problems that we grow mentally and spiritually. When we desire to encourage the growth of the human spirit, we challenge and encourage the human capacity to solve problems, just as in school we deliberately set problems for our children to solve. It is through the pain of confronting problems that we learn.
