A Clock for Eternity (Aug, 1951)
Article about an incredible clock designed and built by a Danish Locksmith that was supposed to be accurate for several millenia. In addition the clock was to provide a dozen different kinds of astronomical data such as the the phases of the moon, precession and the orbits of the planets (Pluto is absent, I don’t think it had been discovered when the design was started).
In 1991 it was noted that many of its measurements were wrong. An examination found that grime and corrosion had were the culprits and from 1995-97 the clock was dismantled and restored.
More information on the restoration here.
A very similar, but much more ambitious and technically complex project is currently being undertaken by the Long Now Foundation. Led by Danny Hillis (founder of Thinking Machines and general all round genius) they are attempting to build a clock that will run for 10,000 years. Check out the project page for more information.
A Clock for Eternity
Jens Olsen, a little Danish craftsman â€” you’d have taken him for Santa Claus -â€” died before he finished the incredible task he set for himself. His countrymen have completed his life’s work for himâ€”

LATE THIS YEAR a new clock will start ticking away in the old Town Hall at Copenhagen, Denmark. It is not an ordinary clock, for this is a timepiece built for eternity, a mechanism that will keep an accurate record of the time throughout the solar system, a clock we expect to tick away for three or four thousand years.
The maze of gears and shafts in our clock is so accurate that the pointer showing the eclipses of the sun and moon makes one revolution in precisely 6798.36152 days!
Pinching Your way to Success (Apr, 1958)
Apparently when a man decides to do something about his future, he starts by pinching his nipples.
WHAT HAPPENS WHEN A MAN DECIDES TO DO SOMETHING ABOUT HIS FUTURE!
The proven rule of “learn more to earn more” took M.E.F. (name on request) from a position of truck driver to that of an accounting executive in sixteen months. Listen to what M.E.F. says:
World’s Tiniest TV Camera (Apr, 1956)
For 1956 that is actually an impressively small camera.
World’s Tiniest TV Camera
Telecasting of programs by means of a TV camera palmed in the operator’s hand is forecast as a result of the recent development of a new electronic device in West Germany. As shown in the photo (left), the video pickup is smaller than many microphones. Heart of the instrument is a miniature tube called the ‘Mini-Resitron.”
This camera works in pretty much the same way as conventional, larger TV “eyes,” converting optical images into electrical signals. Operation depends largely on a sensitive layer of semi-conductor material developed by Prof. I. Walter Heimann. The inside of the camera is an amazingly compact array of tiny components and intricate wiring. Subminia-ture tubes and other parts are clustered around the “Mini-Resitron,” while a flexible metal hose is wrapped around the cable that leads from the camera.
Still in the experimental stage, the new unit will probably go into production some time later this year.
ASCII Art – 1948 (Oct, 1948)
This would be a lot of fun without a text editor. One mistake and you have to start over.

WHILE purely entertaining, doodling with a typewriter gives vent to the imagination and originality of both the experienced and the hunt-and-peck typist. Fill-in pictures are the easiest to “draw” with a typewriter. An example is shown in the flower which is made with the letter X alone. Such pictures, whether a flower or a portrait, are made by using an outline of the subject as a typing guide. This is done by tracing the outline lightly on paper and backing it with carbon paper to type the picture. Caricature or cartoon “drawing” combines letters with symbols as shown in the examples below. Here, half-spacing of the typewriter is required, as in the case of the owl’s beak and feet. The log cabin shows what can be done in drawing a picture in perspective.
BARRED â€” because he couldn’t entertain (Mar, 1933)
Apparently in the 1930’s failure to play an instrument was a punishable offence.
BARRED â€” because he couldn’t entertain
ARE you, too, ruled out, barred from parties and popularity? You are probably just as attractive, interesting, clever as any one else. Yet others always capture all the good times while you alone are left out in the cold.
Why? Find out why and the bars that shut you out will fade away and disappear. Most people who miss popularity are themselves to blame. Friends would invite you out if only you had something to add to the general gaiety. For that is why we have parties … to entertain each other.
FUN with QUICKSILVER (Apr, 1939)
Last week we had an article on how to make Nitrous Oxide, today we have fun experiments you can do with mercury, a poison. Mercury is considered toxic enough that when it is spilled in schools they are routinely closed and decontaminated. The article does point out that it is a poison and should be handled with care, then goes on to explain how to build a little straw-device for picking up stray globs of mercury. While this device does prevent you from sucking up mercury, it does nothing about the fumes.
Just to be clear: Mercury is a poison, it can cause neruological damage, it can give you cancer, it can kill you. Do not do any of these experiments.

Mercury, the Liquid Mystery Metal, Offers a Fascinating Field of Experiment to Amateur-Chemistry Enthusiasts
MERCURY seems to be nature’s joke on the scientist. The only metal that is liquid at ordinary temperaatures, it still outweighs most solid ones-lead included. Volume for volume, among all the substances you encounter in your everyday life, only a few such as platiinum, “gold, and tungsten are heavier than mercury. Though it runs like water, it does not wet objects, and a drop of mercury in the palm of your hand is so elusive that it defies you to pick it up with your fingers.
