好難揀.....

ha...I have voted SR+GR

GR without math...such a difficult topic for the speaker!

[WenXP]

I found that there will be quite a few (more than 5) audience who have F.7 Maths background... So a little maths can be introduced I think. But the speaker must place emphasis on the concepts rather than the maths!

[quantumkit]

I heard that the high school syllabus has been changed a lot...so what would be the minimal math requirement (or recommended knowledge)??

1. vector: decomposition(A^=Ax x^+ Ay x^ + Az z^),addition, dot product

2. differentiation: e.g. rate of change: displacement => velocity => acceleration
3. coordinates systems in 2D (or 3D): cartisian, polar(r, theta, phi)

I think there are not much math requirement of special relativity.

For GR, it's better for us to know what exactly audience want to know about the topic. Here are some examples:

1. Basic idea: Principle of Equivalence

2. Some "classical tests" of GR:
a. Bending of star light near Sun
b. 水星進動

3. Some applications/observations/predictions (less math)
a. Global Positioning System (GPS)
b. Gravitation Waves 重力波
c. Gravitational Redshift 重力紅移
d. Gravitational lensing 重力透鏡

4. Some theoretical topics (more math)
a. Tidal force (潮汐力)
b. Measure of curvature
c. Measure of distance : line element,g metric
d. Geodesics (測地線)
e. Orbits in GR (no more kepler's laws...), Light orbit
f. Einstein's Field Equation (***Hardest***)
g. Some solutions to the field equation: physics of black holes

5. Observational aspects of GR
a. Decreasing period of binary neutron stars
b. Frame dragging
...

6. Topics on Cosmology (宇宙學)
a. Cosmological Principle
b. Friedmann Equations
...

So there are many many topics that can be chosen for the talk. Just pick something you want to know more~

WenXP,

可否Clarify以上的投票是其中的一個研討會的專題, 還是兩個研討會都圍繞這個專題呢 ?

後者是也!!
