December 17, 1900 The Search for Extraterrestrial Intelligence

On December 17, 1900, the French Academy of Science offered a prize of 100,000 francs to the first person to make contact with an alien civilization.  Provided that it was anything but Martian.  That was considered too easy.

In the 5th century BC, the Greek philosopher Democritus taught that the world was made of atoms.  Physically indestructible and always in motion, these atoms are infinite in number, differing only in shape and size.  Democritus taught that everything around us is the result of physical laws without reason or purpose, asking only “what circumstances caused this event?”

Philosophers like Aristotle and Socrates took a less mechanistic approach, asking “What purpose did this event serve?” Plato disliked Democritus so much that he wanted to burn all his books.

The prevailing view throughout antiquity was that our planet is special, that we are alone in the cosmos.  Democritus believed there were infinite numbers of worlds such as our own, with inhabitants like ourselves.

In the time of Copernicus, it was widely believed that there is life on other planets.  Astronomers saw several features of the moon as evidence, if not of life, then at least that intelligent life had once paid a visit.

Interest in Mars began to develop in the 1870s, when the Italian astronomer Giovanni Virginio Schiaparelli described physical features of the red planet as “canali”.  The word means “channels” in Italian, but it was mis-translated as “canals”.  The English speaking world was off to the races.

Speculation and folklore about intelligent life on Mars was soon replaced by a popular near-certainty that canals were excavated by Martians.

The idea was near universal by the turn of the century.  On this day, December 17, 1900, the French Academy of Science offered a prize of 100,000 francs to the first person to make contact with an alien civilization.  Provided that it was anything but Martian.  That was considered too easy.

In 1924, the idea was put to the test.  Believing that martians might attempt to communicate on the day the two bodies were in closest proximity, August 21, 1924 became “National Radio Silence Day”.  Americans were urged to observe “radio silence” for the first five minutes of every hour, while a radio receiver at the U.S. Naval Observatory, two miles aloft on board a dirigible, listened for the signal that never came.

Wells wrote the War of the Worlds in 1897, telling the story of an alien earth invasion by Martians fleeing the desiccation of their own planet.  The story was adapted to a radio drama broadcast on Halloween, 1938, a production so realistic that many listeners sued the network for “mental anguish” and “personal injury”.

The idea of life on Mars persisted until the 1960s, when close observations of the Martian surface were made possible by the Mariner series of spacecraft.

While much of “mainstream” science seems to steer clear of the subject, the University of California at Berkeley is running a “distributed computing effort” to identify extraterrestrial life, called “SETI@home”.

The website explains the mission:  “SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data”.

With an original objective of 50,000-100,000 home computers, SETI@home had 1,525,050 users as of January 2015.  With the introduction of the Berkeley Open Infrastructure for Network Computing, or “BOINC” (I didn’t make that up), SETI@home users can even compete with one another, to see who can process the most “work units”.

You, too can participate at http://setiathome.berkeley.edu/, on your Windows, Apple or Network PC, or your Sony PlayStation 3.  Please let me know if you make contact.

I'm not a "Historian". I'm a husband, a father, a son and a grandfather. A history geek and sometimes curmudgeon, who still likes to learn new things. I began writing "Today in History" nearly six years ago, as sort of a self-guided history course.  I told myself I’d write 365, the leap year changed that to 366. As I write this, I believe there are over 600. I make every effort to get my facts straight, but I'm as good at being wrong as the next guy. I offer these "Today in History" stories in hopes that you'll enjoy reading them, as much as I’ve enjoyed writing them. Rick Long
