ENGINEERS DEVELOP TRANSPARENT COATING TO IMPROVE SOLAR PANEL EFFICIENCY
A team of engineers from Stanford have developed a transparent overlay, made of patterned silica material that helps cool the solar cells as the sun heats them up. The equipment was tested with a custom made solar absorber that behaves identical to a solar cell except that it does not produce electricity like solar cell. The testing reveled that it can reduce the temperature of the absorber by as much as 23 degrees F. This will result in improving the efficiency of the solar cell by certain percentage. The basic principle behind this overlay is that it blocks the infrared light. The tricky part here is not to block the useful wavelengths of light. KNOW MORE
Here is a truly amazing lecture to school students on Prime numbers:–
This talk engages viewers totally for the entire duration taking them through the fantastic world of Prime numbers. What makes it more interesting is the simplistic way Mathematician Vicky Neale, currently a lecturer at University of Oxford, approaches the subject. The fact that there are infinitely many prime numbers, followed by the prime number theorem followed by a fascinating conclusion that other than 2 and 3, all the prime numbers are either 1 more than a multiple of 6 or 1 less than a multiple of 6. Vicky gave this talk on 9th June 2015 to an audience of A-level math students. It is a part of the mathematics enrichment day organized by Millennium mathematics project with a special focus on encouraging creative Mathematical thinking. KNOW MORE
WORLD WILDLIFE WEEK
LET US RAISE OUR VOICE FOR THE ONES WITH NO VOICE
Wild life refers to non-domesticated animal species, but also includes all plants, fungi and other organisms that live or grow in a wild area and are untouched by humans. Wild life is found in all types of ecosystem which include desserts, rain forests, forests, grasslands, plains and other areas including the most developed urban sites. It is believed by most of the scientists that much wild life is unaffected by human activities. If we look into the history it is seen that humans have separated civilization from wild life in many number of ways which include the legal, social and moral sense. However some animals have been adapted to suburban environment and they include domesticated animals such as cats, mice, dogs, gerbils. Certain animals were considered to be sacred for many religions. For example, cow is a religious animal for Hindus while the Native Americans have a great cultural and spiritual value for eagles, hawks and their feathers.
According to the report of World Wildlife Fund the global wildlife population has decreased by 52% between 1970 and 2014. Earth has lost half of its wild life in past forty years. The research by scientists at WWF and the zoological society of London revealed that creatures across land, rivers and the seas are being wiped out because humans are killing them for food while polluting and destroying their habitat.
So friends it’s high time for us to raise voice against the human activities that are leading to the destruction of wild life. Let’s protect wild life and thereby protect ourselves.
WORLD WILD LIFE WEEK
In the year 1952 the government of India established an Indian Board of Wild Life (IBWL) with a view to preserve the fauna of India, particularly to take immediate steps to prevent extinction of any species. Since then the board has been doing a great work to create public awareness in favour of wild life preservation.
From a very long time, our wild life has been closely associated with our folklore and legendary beliefs, with our epics and our history. Our lives would be very poor without these various life forms that built up nature. Wild life preservation is all about the active and planned wild life management under which all the life forms would progress along with humans, each in its own sphere of influence and utility and without causing any damage to human interests. Different wild life sanctuaries and national parks have been developed in suitable localities all over the country with the view to preserve wild life.
The Indian Board of Wild Life (IBWL) has planned to celebrate Wildlife week during the first week of October (2nd-8th) in order to create awareness in common man in favour of protection of wildlife.
During this week environmentalists, governments, activists and educators organize various activities to improve awareness regarding wildlife conservation among people. India is able to manage several conferences, public meetings and awareness programs among the nature lovers since it’s a mega-storehouse of various species. Schools and educational institutions celebrate this week by organizing events such as paintings competition, essay writing, debate competition for young children with wildlife as the theme. They also educate children by playing wildlife related movies. Today’s kids are tomorrow’s future therefore by educating them regarding wild life conservation we can bring a change in human mind regarding the importance of wildlife. We need to educate them in such a way that they get to know the importance of wildlife in their own life.
However, this week is not only about creating awareness in people about wild life but also to work with the government and help them design strategies and form policies favoring solutions that address wildlife conservation in today’s changing circumstances.
