infinity.ppt

Short talk entitled 'To Infinity and Beyond' which I've given
to various primary schools' groups. Loosely on the theme of
'what's it like to be an astronaut'.

sunmoon.ppt

Talk on the use of the Sun and Moon as timekeepers, the apparent
motion of the stars due to the Earth's rotation, the origin of 
the seasons, the phases of the Moon, eclipses etc.

solar_system.ppt

Pictorial tour of the solar system, starting from the Earth and Moon,
the Sun, then working outwards through the planets. (Haven't done
this talk for some time, so a few of the images are looking dated -
e.g. no Cassini images of Saturn).

venus.ppt

Talk on the history and science behind the Transit of Venus. Charts
developing understanding of the solar system from Ptolemaic times,
showing how we came to understand that the Earth goes round the Sun
and how transit observations could be used to measure size of the
solar system.
