Most things we use as time machines move in a periodic, harmonic way, and we tell the time by counting the ticks, or oscillations. The young members of the audience experiment with the transformation of oscillations into waves, and look at sounds and listen to pictures.

The High Chaparral is the home of a pioneer family in the newly won West; is the prize the settlers must hold against outlaws and Indians; and spells adventure in the wild Arizona territory of 1870.

Apaches capture Victoria believing that she has magic healing powers which can save the life of their Chief's wounded son. The penalty for her failure is death-and Victoria quickly realises that the boy is far beyond any human aid.

Should a mother feed her baby from the breast or from a bottle? Does breast feeding hurt? Is it unpleasant or messy?

This week's programme in the series on Man and Science Today.
'I don't want us to look at space as something extraordinary; that's not really part of us, a place where you make stunts or where you make big deals with lots of oohs and aahs. I want this to be a regular, run-of-the-mill operation... the moon is just another world.' (Space scientist, Kraft Ehricke)
Today in Houston, Texas, one of the most important scientific conferences of all time begins as scientists meet to present the results of their lunar sample experiments.
The moon rocks, the focus of a deep-rooted clash between NASA engineers and lunar scientists, feature strongly in tonight's film as it traces their progress from the moon's surface through the rigours of the Lunar Receiving Laboratory to the experiments of the scientific community.
The film peels off the protective skin of headlines from the space programme in an attempt to get closer to the real reasons for its problems and its achievements.
