A story that I use with my Year 10s each year about using Trigonometry “in the field”. I used to work in telecommunications, and used trigonometry to calculate the height of trees.

The story of the number 1 is the story of Western civilisation. Terry Jones, of Monty Python fame, goes on a humour-filled journey to discover just what an amazing tale lies behind the simplest number we have. Using Pythonesque computer graphics, 1 is brought to life in all its various guises.

A maths lesson activity with a toy car.The video shows the results when the car is pulled back 5 cm, 15cm and 25 cm.
In Part Two of the video, the results are shown when the car is pulled back 10 cm, 20 cm and 30 cm.My thought is that the teacher would show the first three results and make a table of the data. Then, make predictions for 10 cm, 20 cm and 30 cm.See mathsclass.net blog.

5 minute extract from the film “Agora” – an imagined biography of Hypatia of Alexandria. Suggests Hypatia may have worked out the elliptical orbit of the planets around the sun (possible given her commentaries on Apollonius and work on astronomy – but history records this was done by Kepler 1300 years later). This YouTube version has subtitles burnt in – but other versions have poor sound.
