Quantum Gravity for Astronomers.

In a nutshell, astronomers study gravity; specifically the gravity of very large scale problems - planets, stars, galaxies and clusters. The study of very small scale gravitational effects - effects on quantum scales - then usually go unnoticed in the world of astronomy. In this very introductory talk, I will summarise the view of gravity as a particle physicist would see it. In this way, I will try introduce some of the excitement and some of the problems with trying to study gravity on the very smallest scales without the immense (albeit powerful) technical machinery of differential geometry. In the end I hope to convince you that even though quantum gravitiational effects may be very very difficult to observe in the sky today, we still have an enormous amount to learn about the Universe we live in from their study.
