Chinese takeaway

I ordered a Chinese takeaway from a local place, just been to pick it up and as I was driving home, I heard the bags rustling and moving!!

I thought what on Earth is that. Has something got in the bag? I thought I could see a little pair of eyes peering out at me.

I was driving so I leaned forward, picked up the bag, put it on the passenger seat and there it was again, more rustling and little eyes looking out from behind the prawn crackers.

I thought it’s got to be a rat or a mouse or something, so I carefully pulled the bag down ...

And there it was ...

... A Peking Duck!

Walter Noddack

Born 17 Aug 1893; died 7 Dec 1960 at age 67.Walter Karl Friedrich Noddack was a German chemist who discovered the element rhenium (Jun 1925) in collaboration with his wife Ida Tacke. In 1922, he began a long search for undiscovered elements. After three years, the careful fractionation of certain ores yielded element 75, a rare heavy metallic element that resembles manganese. Named rhenium after the Rhine River, it was the last stable element to be discovered. Noddack is also remembered for arguing for a concept he called allgegenwartskonzentration or, literally, omnipresent concentration. This idea, reminiscent of Greek philosopher Anaxagoras, assumed that every mineral actually contained every element. The reason they could not all be detected was they existed in too small quantities.
