Latest paper claim to have achieved a sharp focussing of light to 0.4 times the wave length, creating a new record. How can we explain this in wave theory?
Every one assume that most of the pollution is caused by vehicles. In Dubai, I have seen much larger vehicular traffic than in India, but the pollution is almost nil. The photo here is of...
