Beneath the surface of the world are the rules of science. But beneath them there is the far deeper set of rules. A matrix of pure mathematics which explains the nature of the rules of science and how it is that we can understand them in the first place.

More than one billion cellular devices are now shipped each year to more than four billion subscribers worldwide. More than half will soon support wide-area broadband access to the Internet with devices that are increasingly more powerful, more compact and less expensive than their predecessors. Irwin Jacobs, co-founder of Qualcomm, will touch on the history of the wireless telecommunications research and development company, and explore further developments in wireless technology, devices and applications.

Genetic imbalances—such as those associated with Down syndrome in humans—are generally harmful. The number of copies of a given gene, the gene dose, can be very important. In the roundworm, C. elegans, sex (male or hermaphrodite) is determined by the number of X chromosomes. Dr. Barbara Meyer explains how hermaphrodites control gene expression on their pair of X chromosomes to avoid having double the gene dose of males. By studying these sophisticated genetic systems in worms, scientists can learn more about related molecular pathways in mammals and humans.

The Story of India is a BBC TV documentary series, written and presented by historian Michael Wood, about the 10,000-year history of the Indian subcontinent in six episodes.

60 years ago India threw off the chains of British Empire and became a free nation. And now the worlds largest democracy is rushing in to the future.

As in most of his documentaries, Wood explains historical events by travelling to the places where they took place, examining archeological and historical evidence at first hand and interviewing historians and archaeologists, as well as chatting with local people.

More than a thousand years ago deep in the jungle of Northern Cambodia a civilization was that built most largest and most beauty-full temples the world has ever seen. Than mysteriously they vanished. How did they create such beauty? And why did they abandon these jewels in the jungle.

It is five times hotter than the sun and turns sand to glass in an instant. It can shoot 80 kilometres up above storm clouds. And it may even have provided the original spark that created life itself. This pacy, stylish documentary reveals the full power of lightning, why it is so dangerous, and what scientists are doing to protect us.

Venus, the Sun’s second planet, is a dark, broiling oven. It is a high-pressure, volcanic world with temperatures soaring above 500 degrees Celsius and air choked with carbon dioxide. How can the planets Earth and Venus, so similar in size and composition, be so different?
