Many thousands of years separate the creators of the pictogram but it is difficult to avoid the feeling that the unknown Ice Age artist, working on a wall of a French cave, and a mind as modern as that of Carl Sagan, the astronomer, who designed this 6-inch by 9-8nch gold-anodized aluminum plate to be attached to the antenna of the spacecraft Pioneer 10, before it was launched into deep space in 1972. . . . . Sagan by contrast, has given a written explanation of every part of this plaque. ‘It is written in the only language we share with the recipients: Science.’ . . . Hydrogen being the most abundant element in our galaxy, and physics being assumed to obey the same laws throughout our galaxy, this part of the message should communicate to an advanced civilization coming across Pioneer 10 tens of thousands of years from now. The extraterrestrials should be able to calculate that the plaque belongs to a very small value of the Milky Way Galaxy and a single year in the history of the galaxy (1970). The sun and planets shown along the bottom of the plaque should allow the exact location to be pinpointed; and the drawing of the spacecraft leaving the solar system will surely be understoopd. But what will the unknown being red into the human figures, which to us are the most obvious part of the message? They are likely to prove much more elusive than the meaning of the Ice Age ox is to us. ‘The human beings,’ says Sagan, ‘are the most mysterious part of the message.’ ~ Page 217

. . . . Steven Weinberg, en.wikipedia.org/wiki/Steven_Weinberga Nobel prize-winning physicist, expressed this view when he wrote ‘when we make contact with beings from another planet we will find that they have discovered the same laws of physical science as we have.’ Science is thus a cross-cultural language which any culture can in principle learn to speak, and which any technologically sophisticated culture will already have learnt to speak. This was the assumption underlying a message that was broadcast into space by the Arecibo radio telescope in 1974. The message consisted of the numbers one through to ten, the atomic numbers of hydrogen, carbon, nitrogen, oxygen and phosphorus, and formulas for the sugars and bases in the nucleotides of DNA, a figure of human being and its height, the population of Earth, a diagram of our solar system, and an image of the Arecibo telescope with its diameter. The assumption was that any extraterrestrial intelligence capable of receiving the message would recognize the maths and the science and quickly make sense of the Earth-specific information. The great mathematician Christian Huygens discovered the law of the pendulum in 1673; he believed that there were inhabited planets scattered across the universe; and by the time he died in 1695 he had persuaded himself that this law was known throughout the universe. ` Page 528
