is there a "brand logo" for natural science? I had posted an earlier version of this somewhere on this forum sometime ago, but in order as not to make things too easy for you, I'm now posting this thing again. So guess what this is! Whenever I watch movies like "Contact", or also in the context of the "hello aliens" gold plates on the Voyager/Pioneer devices, I wonder if it is possible to create a pictogram that allows totally different (but advanced) cultures to draw some conclusions about our society or scientific knowledge or whatever. I mean, we recognize the shapes of a greeting man and woman on the Voyager plate because we have have neuronal circuitry that says "genetically compatible being detected! mating device engaged!" or at least "hi there people!" when an optical input resembling these shapes reach our brain. But what would we be able to tell someone who has not had our "education"? Someone whose ancestors did not shoot arrows at each other so we now can use lines and arrows as a means of depicting motion or forces? someone whose people knows it's living on a near-spherical planet but which never had the idea to put a graduation over its surface? or, to be more realistic, someone who does not think of gravity when reading "g" because he prefers to call it "Schwerkraft", or worse, uses a different alphabet? how do you give someone like this "poor" guy an idea of what our current scientific theories say? assume he knows more that we know and wants to know if we're worth talking to? additionally, what would be a good "brand logo" for natural sciences compared to the traditional religious or semi-political symbols like crosses, half moons, five- or six-pointed stars, eagles... contemplating all this I came up with a thing that looks like this: http://home.arcor.de/dawidi/misc/fourforces2.png now, to test my design among you science experts before I print it on a sweatshirt (I don't have a gold plate to put it on ), what do you see in this picture, considering what I said above?
