The Secret Life of Your Bodyclock

If you’re reading this any time after lunch and you’re not dead, well done. You have, in the words of Professor Russell Foster, a chronobiologist, “survived the most dangerous part of the day”. Chronobiologists study the body’s various internal clocks. In this documentary, specialists reveal, among other things, that you are three times more likely to have a heart attack between 6.00am and noon, when the blood is stickier and the vessels stiffer. These are the “danger hours”.




Why are you more likely to have a heart attack at eight o'clock in the morning or crash your car on the motorway at two o'clock in the afternoon? Can taking your medication at the right time of day really save your life? And have you ever wondered why teenagers will not get out of bed in the morning?

The answers to these questions lie in the secret world of the biological clock.

Thunderbolts of the Gods

Thanks to Andreas for suggesting this documentary - Thunderbolts of the Gods introduces the reader to a former age of planetary instability and earthshaking electrical events, and offers a revolutionary synthesis of historical investigation and the newly discovered Electric Universe. Solar system cosmic upheaval occurred so recently as to have profoundly affected early human cultures, provoking incomprehensible myths, symbols, and commemorative practices.




Through a synthesis of ancient testimony, high-energy plasma experiments, and space age discoveries, the authors bring the ancient world to life. If their hypothesis is correct, it will surely alter many paths of scientific investigation as well. The little-known study of powerful electrical discharges in plasma is a new and exciting development in plasma cosmology , with profound implication for space age astronomy.

To advance their case, the authors present side-by-side comparisons of laboratory plasma experiments and globally recurring symbols of the ancient sky. The evidence, they report, shows an ancient obsession with extremely violent electrical discharge formations in the heavens.

Fractals - The Colors Of Infinity

Arthur C. Clarke, through interviews with scientists and mathematicians like Benoit Mandlebrot, use the popular Mandlebrot Set to explore how easy formulas can bring about intricate results. It is also used in an attempt to answer questions about the longevity of the universe.




Benoit Mandelbrot discovered what is now called the M-Set in the early seventies and coined the term fractal to describe the geometry behind it. The power and the beauty of fractals were only capable of being seen with the advent of computers, which become psychedelic windows on the infinite when using simple fractal equations.

In 1992 Nigel Lesmoir-Gordon made the TV documentary, The Colors of Infinity about the Mandelbrot Set and fractals, which has since been seen right round the world. Nigel s enthusiasm brought together a dream team of contributors for the film who all now contribute to the book tracking how fractals have developed since the film was made. Sir Arthur C Clarke presented the film and in the book gives a lucidly simple account of the mathematics of the M-Set.

Freeze Me

Cryogenics is an extremely controversial subject...what do you think?

Science and Islam

Physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries.

Its legacy is tangible, with terms like algebra, algorithm and alkali all being Arabic in origin and at the very heart of modern science - there would be no modern mathematics or physics without algebra, no computers without algorithms and no chemistry without alkalis.

For Baghdad-born Al-Khalili this is also a personal journey and on his travels he uncovers a diverse and outward-looking culture, fascinated by learning and obsessed with science. From the great mathematician Al-Khwarizmi, who did much to establish the mathematical tradition we now know as algebra, to Ibn Sina, a pioneer of early medicine whose Canon of Medicine was still in use as recently as the 19th century, he pieces together a remarkable story of the often-overlooked achievements of the early medieval Islamic scientists.

Nikola Tesla - Genius Who Lit the World

This program reveals the discoveries of a forgotten genius, many of which went virtually unnoticed for nearly a century. Nikola Tesla is considered the father of our modern technological age and one of the most mysterious and controversial scientists in history. How did this obscure visionary from what is now Yugoslavia lay the foundation for modern communications and energy research?




Nikola Tesla’s contributions to science and technology include the invention of radio, television, radio-astronomy, remote control and robotics, radar, medical x-ray and the wireless transmission of electricity. Many of Nikola Tesla’s inventions were and in some cases still are considered a little too revolutionary by government agencies and the power brokers of the time and are discussed in detail in this program.

Encyclopedia Britannica lists Nikola Tesla as one of the top ten most fascinating people in history. So why is he virtually unknown to the general public? This program is a penetrating study of the life and mind of a "scientific superman" who, against all odds, dedicated his life to the task of designing and improving technology for the service and advancement of humanity.

Homeopathy: The Test

Homeopathy was pioneered over 200 years ago. Practitioners and patients are convinced it has the power to heal. Today, some of the most famous and influential people in the world, including pop stars, politicians, footballers and even Prince Charles, all use homeopathic remedies. Yet according to traditional science, they are wasting their money.




The Challenge
Sceptic James Randi is so convinced that homeopathy will not work, that he has offered $1m to anyone who can provide convincing evidence of its effects. For the first time in the programme's history, Horizon conducts its own scientific experiment, to try and win his money. If they succeed, they will not only be $1m richer - they will also force scientists to rethink some of their fundamental beliefs.

Homeopathy and conventional science
The basic principle of homeopathy is that like cures like: that an ailment can be cured by small quantities of substances which produce the same symptoms. For example, it is believed that onions, which produce streaming, itchy eyes, can be used to relieve the symptoms of hay fever.

However, many of the ingredients of homeopathic cures are poisonous if taken in large enough quantities. So homeopaths dilute the substances they are using in water or alcohol. This is where scientists become sceptical - because homeopathic solutions are diluted so many times they are unlikely to contain any of the original ingredients at all.

Yet many of the people who take homeopathic medicines are convinced that they work. Has science missed something, or could there be a more conventional explanation?

The Placebo Effect
The placebo effect is a well-documented medical phenomenon. Often, a patient taking pills will feel better, regardless of what the pills contain, simply because they believe the pills will work. Doctors studying the placebo effect have noticed that large pills work better than small pills, and that coloured pills work better than white ones.

Could the beneficial effects of homeopathy be entirely due to the placebo effect? If so, then homeopathy ought not to work on babies or animals, who have no knowledge that they are taking a medicine. Yet many people are convinced that it does.

Can science prove that homeopathy works?
In 1988, Jacques Benveniste was studying how allergies affected the body. He focussed on a type of blood cell known as a basophil, which activates when it comes into contact with a substance you're allergic to.

As part of his research, Benveniste experimented with very dilute solutions. To his surprise, his research showed that even when the allergic substance was diluted down to homeopathic quantities, it could still trigger a reaction in the basophils. Was this the scientific proof that homeopathic medicines could have a measurable effect on the body?

The memory of water
In an attempt to explain his results, Benveniste suggested a startling new theory. He proposed that water had the power to 'remember' substances that had been dissolved in it. This startling new idea would force scientists to rethink many fundamental ideas about how liquids behave.

Unsurprisingly, the scientific community greeted this idea with scepticism. The then editor of Nature, Sir John Maddox, agreed to publish Benveniste's paper - but on one condition. Benveniste must open his laboratory to a team of independent referees, who would evaluate his techniques.

The Dark Secret Of Hendrik Schön

Imagine a world where disease could be eradicated by an injection of tiny robots the size of molecules. That is the hope offered by nanotechnology - the science of microscopically small machines. But others fear nanotechnology could lead to a non-biological cancer - where swarms of tiny nanobots come together and literally devour human flesh.

Sounds like science fiction? It certainly did until a brilliant young scientist called Hendrik Schön seemed to bring it a step closer.

Schön's great breakthrough was to make a computer transistor out of a single organic molecule. It was an achievement of almost incalculable brilliance. Some speculated this technology could spell the end of the entire silicon chip industry.

Crucially, Schön's transistor was organic. Suddenly, this seemed to be the first step towards true nanotechnology, where minute computers could grow as living cells.

Scientists speculated about how these tiny machines could be used to target diseases with astonishing precision. Others wondered - could the military use them as a new weapon? Others, including Prince Charles, were terrified. If these machines can grow by themselves, how do we stop them from growing?

What happened next would destroy reputations and shatter lives - because there was more to Hendrik Schön's discovery than anyone knew.
