Volcanoes have a fearsome reputation. In reality, they are the most important force in the creation of the planet as we know it today. Iain abseils into a lava lake and cave dives in a cenote to show how the heat that fuels volcanoes also drives some of the most fundamental processes on the planet.
Ice may be nothing more than frozen water but, as Iain explains, it holds extraordinary power. Descending 150m down a frozen waterfall, he sees a glacier in action from below and discovers why the huge Jacobshaven glacier is retreating, he shows how it shaped our past and may now threaten our future.
Travelling from Hawaii to the Amazon and Ethiopia and then on to the Mediterranean, Iain tells the story of the oceans – fierce waves, huge tidal bores, global currents and the future dangers of global warming.
Iain looks at the big picture of Earth's place in space. It's taken four and a half billions years and several great catastrophes to turn it from a barren rock to the unique planet we know today.

The Planets - 1 - Different Worlds [BBC, 1999]
While watching The Planets, be prepared to fight your way past all kinds of computer animation which makes Walking with Dinosaurs seem like the last word in realism. It seems that no solar or planetary event which ever happened (or which may or may not have happened) is worthy of mention here without recourse to lovingly detailed shots of implausible-looking collisions and explosions. These come complete with sound effects, despite the fact that there is no sound in the vacuum of space, and are enhanced by a range of colours, some of which are visible only to bees. Somehow Patrick Mooreâs The Sky at Night manages to convey just as much excitement with little more than a couple of diagrams and the presenterâs hyperactive enthusiasm. Fortunately, this two-DVD set is redeemed by both its subject matter and its sheer scope, offering all eight 50-minute episodes of the 1999 documentary series covering the history of the solar system and humanityâs age-old desire to learn its secrets. Detailed indexing and scene access makes this a convenient reference source too, so amateur astronomers everywhere can finally bin those off-air VHS copies. Contains all eight episodes from the series:- âDifferent Worldsâ, âMoonâ, âTerra Firmaâ, âGiantsâ, âStarâ, âAtmosphereâ, âDestinyâ and âLifeâ. Episode 1 - Different Worlds Travel back in time and space to witness the awesome forces that gave birth to the Sun and the far-flung family of planets that orbit it. From the rocky, superheated surface of Mercury, to the storm-wracked atmosphere of gigantic Jupiter and the distant mysteries of Pluto, this is a richly detailed introduction to the creation, composition and alien landscapes of The Planets

Light! More than meets the Eye - Science of visible light
Light! More than meets the Eye - Science of visible light
The discovery of the double helix structure of DNA is to science what the Mona Lisa is to painting. It's been called the single biggest discovery of all time. But it wasn't just stumbled upon - it was a race. Specifically, it was a race between two teams of young scientists working in Britain, as well as the esteemed chemist Linus Pauling, based in California. Already a Nobel laureate, Pauling may have been the favorite, but the discovery would ultimately be made by his British counterparts. Rosalind Franklin and Maurice Wilkins were trying to identify the structure by studying X-ray diffractions of the DNA molecule. But Jim Watson and Francis Crick studied a little bit of everything -- including, to the consternation of some, the work of their competitors. A few have gone so far as to accuse Watson of stealing Franklin's X-ray work. In any case, Waston and Crick's inquisitive working style ultimately allowed them to determine the DNA structure first, in 1953 -- an achievement that led to their Nobel Prize in 1962. Meanwhile, Franklin passed away in 1958 from cancer.
