I love physics!

So I can't tell if I'm stuck in 'crazy I love physics' mode or if today really was brilliant?! I had three physics lessons and I had so much fun!

So my friends have pretty much decided to buy tickets for the uncaged monkeys, we'll just find someone else to take my ticket if I can't at least maybe I make it! this way it seems like the interview/no interview is a win win situation!

Then I had a physics lesson in which we were talking about simple harmonic motion. I asked if humans have a natural frequency and then we took an interesting turn off topic in which we dicussed stomachs exploding at discos... Basicly when a certain frequency of sound is applied a certain object will vibrate in a way called resonance. A different object will have a different frequency so our bodies will have a frequency at which they will vibrate.

Then with my other teacher we have been doing magnetic fields and today started talking about transformers. This uses AC currents it is incredibly clever so I thought that Nikola Tesla had probably invented it. I checked, he did! It's a bit complicated so I'm not sure I can explain it but it uses the laws of induction. Now I understand how the tesla coil works (basically a transforming to very high voltages) and it is brilliant! This is a video clips from a film using the tesla coils, please excuse the cheesy romance plot line!!
