@Novalis 1368 Physics of the Impossible You mean you read the whole book 'last night'? It talks of the Concept of Impossibility. The author is a theoretical physicist. I have a lot of respect and fear for theoretical physicists. I take a whole night to understand one sentence that they talk about! You are going up in my estimation faster than the ISRO space crafts! You never spoke a truer word! Donkeys are not new to QPQ. In fact, they occupy an adorable status here.
