In fact, 'X-Rays'.
Now we know how the logo looks on the inside :-), with a rubber duck!
Thanks Google, waiting has been worth of it! :)
the first x-ray or röntgen image:
Wasn't this the first one? Of his wife hand made taken on 22 December 1895. The image above was taken on 23 January 1896.
why is there a secret '69' on the background of the two 'o' letters?
Hahahaha, yes noticed that too, but I don't think that it was on purpose given the fact where 69 stands for.......
Is that a pigeon in the small g?
the image i posted was the first x-ray image that was shown in the public.
"röntgen", very happy to see this word here ;-D
Why does the rubber duck have such an image? Included contraband? Or a subtle reference to the use of ducks in optical transforms, related to X-ray diffraction?
arindam It's a pigeon indeed, it refers to PigeonRank according to Marissa Mayer "with a shoutout to April Fools 2002 – PigeonRank – in the little 'g'"
Why do we have a key in Logo? Wat is the importance of key?
Well, it is a skeleton key.
