China reduces solar power costs with large-scale manufacturing



Rating: 4

Over the past decade, China has become the world’s leading manufacturer of solar energy technologies; China’s solar manufacturers have helped drive down the cost of solar power around the world with their large-scale production facilities and solar panel exports. In October, ClimateWorks traveled to China to get a sense of the scale of China’s solar manufacturing efforts and talk to some local experts about China’s goals for dramatically scaling up its domestic deployment of solar energy technologies.

The harmony in the universe (Harun Yahya)



Rating: 2

All scientific research has revealed that a highly detailed and calculated structure pervades the universe in which we live. Many things, visible or invisible, from the viscosity of water to the speed of light, from the structure of the atom to gravity, stem from this feature of the universe. The renowned scientist Albert Einstein describes this harmony that can be observed in every point around us as the grandeur of reason that assumes physical form in the universe. Yet some scientists imagine that this magnificent structure of the universe is the result of a cause and effect relationship that developed over the course of time. Accounting for life and other physical existence in terms of a cause and effect relationship basically depends on material interaction in time. However, there was a moment when there was no matter, no energy, and even no time. Certain scientists, unable to point to any material cause for that moment, are today experiencing great concern and difficulty. The reason for this is the starting point of the universe, the great explosion originally referred to as the Big Bang. The definitive conclusion arrived at by astrophysics is that the entire universe came into being in a zero moment through a huge explosion. The Big Bang has proved that the entire universe came into being through the explosion of a single point, from nothing. The fact that there is a Sun that warms our Earth without burning it or water that functions like a flawless thermostat on

The Manly Man's Guide to the Universe



Rating: 5

Dr. Steven Manly (University of Rochester) gives an overview of basic particle physics and how it ties into cosmology and some of the big questions physicists are pursuing these days.

Renewing India



Rating: 5

‘Renewing India’ is a film on the success stories of alternative and renewable energy projects that were carried out in different parts of India. Featured are micro hydro-power projects from Uttarakhand, solar power plants in Sunderbans, biomass gasifiers in Sunderbans, Kerala, Karnataka and Gujarat, and windmills in Gujarat and Maharashtra. Spanning over three decades, India’s renewable energy programme has travelled a long way and has been a catalyst of change for many villages in rural India that have been living without any modern facilities such as electricity or water. Renewable sources of energy have been a success in every sphere- in terms of technology, markets and innovations and today small and big businesses are discovering the economic viability and pro-environment nature of these energy sources.

The Riddle of AntiMatter



Rating: 5

According to standard theory, the early moments of the universe were marked by the explosive contact between subatomic particles of opposite charge. Featuring short interviews with Masaki Hori, Tokyo University and Jeffrey Hangst, Aarhus University. Scientists are now focusing their most powerful technologies on an effort to figure out exactly what happened. Our understanding of cosmic history hangs on the question: how did matter as we know it survive? And what happened to its birth twin, its opposite, a mysterious substance known as antimatter? A crew of astronauts is making its way to a launch pad at the Kennedy Space Center in Florida. Little noticed in the publicity surrounding the close of this storied program is the cargo bolted into Endeavor’s hold. It’s a science instrument that some hope will become one of the most important scientific contributions of human space flight. It’s a kind of telescope, though it will not return dazzling images of cosmic realms long hidden from view, the distant corners of the universe, or the hidden structure of black holes and exploding stars. Unlike the great observatories that were launched aboard the shuttle, it was not named for a famous astronomer, like Hubble, or the Chandra X-ray observatory. The instrument, called the Alpha Magnetic Spectrometer, or AMS. The promise surrounding this device is that it will enable scientists to look at the universe in a completely new way. Most telescopes are designed to capture photons, so

Physics Nobel Prize 2011 – Brian Schmidt



Rating: 4

The Nobel Prize for physics in 2011 was awarded to Brian Schmidt, Adam Riess, and Saul Perlmutter for discovering that the universe is expanding at an accelerating rate. This finding was completely unexpected because it was thought that gravity should slow the expansion of the cosmos. The best current explanation of why the universe is accelerating is that there is some energy tied to empty space which pushes matter apart. This ‘Dark Energy’ makes up 73% of the universe but is very difficult to detect. Images courtesy of NASA/NASAimages.org and Maritza A. Lara-Lopez

Quantum Fishing for the Higgs Boson



Rating: 4

Hank talks to some VIPs from CERN about the question on everyone’s mind: does the Higgs Boson particle exist? And describes how CERN is going about finding the answer. Hank interviewed Sergio Bertolucci on October 11, 2011 and Rolf Heuer on October 25, 2011. In the time since then, CERN researchers have gotten some tantalizing clues, but the Higgs boson has yet to be found.
