The Pleasure of Finding Things Out

"All sounds travel in waves much the same as ripples in water." Educational film produced by Bray Studios New York, which was the dominant animation studio based in the United States in the years surrounding World War I.

Kate Humble and Helen Czerski reveal the inner workings of the sun and investigate why scientists think changes in the sun's behaviour may have powerful effects on our climate.

Dr Helen Czerski delves into the Horizon archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history.

From Raymond Baxter live on Tomorrow's World testing a new-fangled bulletproof vest on a nervous inventor to Doctor Who's contemporary spin on the War on Terror, British television and the Great British public have been fascinated with the brave new world offered up by science on TV. Narrated by Robert Webb, this documentary takes a fantastic, incisive and funny voyage through the rich heritage of science TV in the UK, from real science programmes (including The Sky At Night, Horizon, Tomorrow's World, The Ascent of Man) to science-fiction (such as The Quatermass Experiment, Doctor Who, Doomwatch, Blake's 7, The Hitchhiker's Guide to the Galaxy), to find out what it tells us about Britain over the last 60 years.

A celebration of the universe, displaying the whole of time, from its start to its final collapse. This film examines all that occurred to prepare the world that stands before us now: science and spirit, birth and death, the grand cosmos and the minute life systems of our planet.

Fascinating - and unintentionally funny - experiments at Austria's famed Institute for Experimental Psychology involve a subject who for several weeks wears special glasses that reverse right and left and up and down. Unexpectedly, these macabre and somehow surrealist experiments reveal that our perception of these aspects of vision is not of an optical nature and cannot be relied on, while the unfortunate, Kafkaesque subject stubbornly struggles through a morass of continuous failures.

This film consists of three parts. The first dramatizes the life of the founder of Soviet astronautics, Konstantin Tsiolkovsky; the second describes the development of rocket technology; and the third visualizes the future with enactments of the first manned spaceflight, spacewalk, space station construction and humans on the moon.

Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.

A philosophical inquiry about the miracle, through the interview with three specialists that seek to understand the specificity of these phenomena.

A world leading team of ultra-low temperature physicists at Lancaster University decided to place a LEGO figure and four LEGO blocks inside their record-breaking dilution refrigerator. This machine - specially made at the University - is the most effective refrigerator in the world, capable of reaching 1.6 millidegrees above absolute zero (minus 273.15 Centigrade), which is about 200,000 times colder than room temperature and 2,000 times colder than deep space.
