Preparation is everything...

This afternoon I have to give my first ever physics lesson. It's about the continuity equation in fluid dynamics. Thankfully, the first lesson is in front of my fellow teacher students and our physics lecturer. I feel like I have been giving this lesson all night in my dreams, but what you see is the real thing.

Unfortunately, I cannot take my trusty Mac, I'll have to make do with a very rusty Windows laptop (oh dear, that's almost asking for trouble, isn't it...)

Wish me luck, I am starting to get nervous....
