RE: Physics
Hahaha

Now coming back to topic. I will tell you an incident which happened when I was kid. I had already told I was [am] a big sci-fi genre fan and used to do lotsa experimental stuff. So once there was a quiz I was participating [I was in 8th std] and the questions were asked GK including physics. At the end there was a tie and they asked to give speech / talk on future technology etc.

I went there and told them about life of Nikola Tesla and his works on Wireless Electricity. Have already told you I am from rural background and none of the people there couldn't understand a bit and I was mocked. And humiliated. Needless to say we lost the quiz and everyone blamed me. I stressed very much on Wireless Electricity, the concept.

Wireless Electricity is like charging your mobile without any wires between charger and the mobile. You send sms by mobile, how about sending electricity over the air ? Wink Imagine a world without wires !

Now, few months ago, I was searching something and stumbled upon a topic were it mentioned wireless technology has been successful ! My heart stopped for a minute and reminded me of my childhood incident and also, a evil smile on my face Big Grin It was the concept which intrigued me always. I had almost stopped reading about physics and follow latest news, due to my busy times, but suddenly, after reading Wireless Electricity, the physics lover inside me charged, electrons jumped to higher orbits and my hairs stood generating static electricity Tongue I was back !

now, Nikola Tesla is the 19th century physicist, who spent almost spent his entire life on Wireless Electricity. I am sure most of people even not heard about him, leave his experiments aside. In 2007, an US Physicist, Marin Soljacic from MIT successfully experimented it with elecromagnetic waves and resonance. They powered a goddamn 60-watt bulb from a power source seven feet away without any wires !

In 2009 Intel showcased same project based on ideas from MITs scientists. As of now, they have achieved 80 percent of efficiency over a distance of one meter clap


his link - http://www.mit.edu/~soljacic/

you can mail him at soljacic@mit.edu

it may be an old news for you as you regularly follow physics, but I am sure still many people are not aware of this Smile

RE: Physics
I don't follow physics, I always tried to skip it. Most of the it always went above my head and nothing properly went inside. But after reading avi's post I am so much interested in it. Hats off to the way he explained, so simple so that noob like me can understand. Charging my mobile without cables ? Oh avi, it's killer !!!
