Voyager Finds Magnetic Foam at Solar System's Edge

The Voyager satellites are now traveling through the outer edge of the solar system, called the heliosheath. Using a computer model based on Voyager data, scientists have shown that the sun's magnetic field becomes bubbly in this region due to reconnection. Because of this, cosmic rays must slowly work their way through the magnetic foam before continuing on toward the sun.

Monkey Plays With Tiger Cubs

Some thing to learn?? from this episode.
we may be tigers but these monkeys play with us don't get irritated and feel defeated.

Stop the revolutions and let education evolve!

Allow education to evolve naturally in line with society -- as it always has -- rather than constantly trying to revolutionise it! Jane Ballantine, a former teacher and mobile-learning enthusiast/entrepreneur, analyzes different methods used to "fix" the education system and their mixed results as well as where the education system is currently going in the UK and overseas in light of the evolution and spread of modern mobile devices. The technology may be changing fast, but humans aren't; and our need for good and inspiring teachers remains.

Jane is an educationalist, e-learning expert and mobile app entrepreneur releasing educational apps She worked as a research scientist and engineer before her passion for education led her to retrain as a teacher. After five years teaching science and maths in London, she left the classroom to create innovative and award-winning e-learning products. Her company, Limitless Learning Limited, specialises in producing web-optimised learning materials for school-aged children

More pedagogic change in 10 years than last 1000 years

Search, links, media sharing, social media, Wikipedia, games, open source etc. are ground breaking shifts in the way we learn, says Donald Clark. Unfortunately, they're not matched by the way we teach. The growing gap between teaching practice and learning practice is acute and growing. 

Donald Clark is an evangelist for the use of technology in learning and has won many awards, notably the 'Outstanding Achievement in e-learning Award'.

Wild Dolphin "Asks" Divers to Help Free Itself from Hook

In this video, a bottle nosed dolphin with limited mobility due to a hook and fishing line restricting a pectoral fin, approaches some divers for help. Diving instructor noticed that the dolphin was hanging around them, and that it wasn't able to move freely. Closer inspection revealed the ocean debris lodged in the fin.

Thankfully, the dolphin not only allowed the divers to attempt to work the line and hook out 

of the fin, but actually shifted its body to make it easier.

The divers were able to remove the fishing line which allowed increased movement for the animal. Unfortunately, the hook was not able to be removed.

This is first time for me to see this type of video, even though the interaction between dolphins and humans is not new, but a this shows wild dolphins know that humans are tech animals and some time they help....

Motion of solar system in the 'Milky way'

Earth, planet we are living revolves around ‘Sun’ for its life.

Please see the planetary motion.

(Animation with details of motion of planets and their moons around the sun in circular paths) 

However today it is know that ‘Sun’ is not stationery, but revolves around the galaxy with a speed of 72,000 Km/hr.

This video depicts the motion of solar system in the Milky Way galaxy.
