BUSY

As a principal I don't know why I made myself busy with electromagnetic radiation, Bohr's model of the hydrogen atom, atomic spectra, Heisenberg's Uncertainty Principle and bla bla... I am a chemistry teacher really and I like physical chemistry. Interesting topics to read even though I have to really do some deep understanding of the content after I left college more than five years ago. But after all I will only take two periods of the eight form 6 periods. Bless me.
