Physics 237
• What to expect?• This will be low-tech on-the-board course.• All course materials will be available on the web.
• Course components and time table.• The time table is my best guess of what can be covered during this
semester.• The first 9 chapters are critical and sufficient time will be allocated to
an in-depth discussion of that material; these chapters are critical forPhysics 246.
• Today’s topic:• The birth of quantum mechanics.• How black-body radiations leads to energy quantization.

Warning: some think my Phy 237 exams are toxic. Continue at your own risk!

3 Minute 56 Second Intermission.
• Since paying attention for 1hour and 15 minutes is hardwhen the topic is physics,let’s take a 3 minute 56second intermission.
• You can:• Stretch out.• Talk to your neighbors.• Ask me a quick question.• Enjoy the fantastic music.
