05 Nov What you need to know about Stellar Evolution?
Stellar Evolution
Stars form from enormous clouds of hydrogen atoms, pulled together by the force of gravity. As the cloud collapses, gravitational potential energy is converted to kinetic energy of the atoms (they are all “falling” toward their common center of mass). If a...

30 Sep What do you need to know about Nuclear Physics and Radioactivity ?
Nuclear Physics and Radioactivity
Radioactivity is spontaneous and random. The probability that an atom will decay remains constant for the entire life of the atom. If you think about it, this is really strange. How can it not matter whether a uranium atom is...
23 Sep What do you know about Atomic Physics ?
Atomic Physics
Rutherford Experiment (aka Geiger-Marsden)
My summary
Rutherford shot alpha particles at a thin film of gold foil
Most of the alpha particles went right through
Some had high angles of deflection
He was shocked when a small number of the...
10 Sep What do you need to know about Thermal Energy?
Thermal Energy Transfer / Greenhouse Effect
Some Background
IB calls this topic Thermal Energy Transfer, but really it’s about the greenhouse effect and climate change. Calling it Thermal Energy Transfer it sounds more physics-y.
Climate change is of course a controversial subject. Before...
20 Aug What do you need to know about Quantum Physics?
The sequence of development of quantum mechanics, summed up for IB students, from me:
(1) Hydrogen atoms emit a discrete spectrum of light. This is our first evidence that energy levels in the atom are quantized. What a mystery! Physicists have never seen something like this before.
(2)...

Thermal physics provided the transition from macroscopic physics to microscopic physics, and electricity is all about electrons, so why are we backtracking now to talk about bouncing springs and wiggling strings?
It’s because waves are going to be essential, ultimately, to our...

I love physics, but I used to think this one topic, thermal physics, was boring. I had to teach it twice before I understood it well enough to see how interesting it really is!

What makes thermal physics interesting is that it provides...
