When you will end short pulses of messages and start give us details. I cant read your mind. WHO are the inventors in Europe , what they did invented in photochemical field , what is the latest mechanical invention is coming from Silvestri. If you will keep writing meaningless posts like before , you will end in my ignore list. You are few does that every time , every post.

I had many german friends before and they play the wise Emmanuel Kant every time.
