Thanks to all at the Lister Hospital in Stevenage especially R.Vosper, J.Terret, Dr. Amerasekera, and the radiology staff for the images. Thank you to my good friends Sheila and Andy Ball for the ultrasound images of their son, and to my brother Matthew for his input. Thank you also to Jane for her support over the last 9 months. I would also like to thank A.Wellbeloved for allowing me the time to liase with the Lister Hospital. Finally a big thank you to all the staff involved at the Science Museum in London especially Martin and Lyndsey, and my fellow OMEs both in the UK and over in the USA.

Although this project is now a finished resource, I am working with my students at school on several ideas with internet learning and discussion groups. We would be very happy to set up a dialogue with other schools and students on a wide range of topics. Any thoughts or comments please email me.
