Why learn physics in
English?
Because English is the
international language of
science.
Physicists ask:
What are the rules of
the game?
Example:
What are the rules?
假设
I can guess
(form a hypothesis)...
Then see if my guess
can predict what
happens next.
预言
Observing…
Observing…
Observing…
Hypothesis:
杀 card makes another player
lose one point of health.
Testing the hypothesis…
Prediction: 曹操 will lose
another point.
Surprise!
Our guess was wrong.
New hypothesis:
杀 card makes another player
lose one life, unless that player
uses a 闪 card.
and so on…
The rules of physics are
the most fundamental
in science.

They apply everywhere,
at every time,
to all types of matter.
