Julius Corbett, a man of fortune, is in love with an extraordinary woman, Nell Morrison, who is an astronomer. She has a particular penchant for Mars, an in particular, is trying to solve the problem of communicating with the Martians. So great is her obsession with this issue that when Julius proposes marriage to her, she says,
(quoted from Love and a Triangle)
“Talk with the Martians,” said she, “and the next day I will become your wife!”

So a dispirited Julius seeks help from his friend, Marston, an Astronomy Professor at Univ. of Chicago. Marston’s idea is to use electricity and mathematics (“We must use that. And the figures must, of course, be geometrical. Geometry is the same throughout all the worlds that are or have been or ever will be.”). Thus do they end up in the great Pampas of Argentina where “illuminated figures two hundred miles each in their greatest measurement” were made, comprising “only the square, equilateral triangle, circle and rightangled triangle.”
Many months later, the observatories on earth see the startling reply from Mars, in the form of all the figures which the earthlings had made as well as a clear geometric figure of a rightangled triangle with squares drawn on each side, indicating knowledge of the Pythagoras Theorem. As the author exults:
(quoted from Love and a Triangle)
“Ah, it required no profound mathematician, no veteran astronomer, to answer such a question! A schoolboy would be equal to the task. The man of Mars might have no physical resemblance to the man of Earth, the people of Mars might resemble our elephants or have wings, but the eternal laws of mathematics and of logic must be the same throughout all space. Two and two make four, and a straight line is the shortest distance between two points throughout the universe. And by adding this figure to the others represented, the Martians had said to the people of Earth as plainly as could have been done in written words of one of our own languages:
’Yes, we understand. We know that you are trying to communicate with us, or with those upon some other world. We reply to you, and we show to you that we can reason by indicating that the square of the hypothenuse of a rightangled triangle is equivalent to the sum of the squares of the other two sides. Hope to hear from you further.’
There was the rightangled triangle, its lines reproduced in unbroken brilliancy, and there were the added lines used in the familiar demonstration, broken at intervals to indicate their use. The famous pons asinorum had become the bridge between two worlds.”

And that is how love and geometry launched an interplanetary discourse.
