1: The cure of the bright
lights
Materials science,
chemistry and technology are all featured in this lecture. Amalgam
replacements for tooth repair are used to provide insights into which
properties are important, what chemistry we can use in order to
provide those properties and finally how technology is used to make
the process more efficient.

2:The light fantastic
Why do we use lasers?
Laser light has some special properties which more usual light
sources do not. This presentation demonstrates the special properties
of laser light and shows how these can be put to good
use.

times? This machine gives the result of 300 trials.

3: Lies, damned lies or
statistics?
How good are we at intuitively
judging probabilities? Should everyone be able to earn more than the
average wage? Is it a scandal that half of all
doctors/dentists/academics are below the national average? An
excursion into statistics and probability which I hope will encourage
critical consideration of the statistics with which we are bombarded
every day. |
4: Lights! Camera!
Action!
Spectroscopy is a
technique used to analyse many substances in order to determine the
constituents. We do it unconsciously when we see colour. In order to
do spectroscopy one needs a source of light, a means of recording
what happens (a camera) and a substance to give some action! This
presentation will show how spectroscopy works and how it is used.

ozone.

5: Gone with the wind.
We rely on the air around us and
would like it to remain clean and breathable. This presentation looks
at what affects structure of the atmosphere. It then examines some of
the chemistry which goes on in the atmosphere in response to inputs
from both natural and man-made sources.

6: Sensor
sensibility
Sensors are used in many
situations to measure the amount of a substance which is present and
allow the amount to be monitored over time. I am helping colleagues
develop state of the art sensors which may have applications in food
packaging. This presentation will look at what we require from
sensors and how these state of the art sensors can provide it.

7:
The sound of science
This presentation looks
at how sound is formed and some of the priciples of musical
instruments. A number of home-made instruments are employed
to demonstrate these during the presentation.
