I think that Mr. Colbert would disagree.
Yesterday… “The Fates” Decided
In the 6th century, B. C, King Croesus of Lydia was told by the Delphic Oracles he could defeat the Persians. Relying on “The Fates” instead of the facts, he took on an enemy he should have known was too strong for him .. .and he was badly beaten. Lack of facts cost him his kingdom and his freedom.
Today… Facts Are What Count
The recent great strides in military science, pure science, commerce, and industry have resulted from modern man’s ability to determine the facts and act accordingly.
Tremendous advances have been made in the past few years in fact-finding machines. Through electronics, great masses of data that would have taken a lifetime to process can now be handled in a few days. Ordinary volumes of work can be done in minutes.
By making “mathematical models” of specific processes, products, or situations, man today can predetermine probable results, minimize risks and costs.

In the mid 50′s every company on earth made their own computers.
What’s 500 times faster than a sliderule?
Today’s quick answer to mathematical problems for engineers and designers is GEDA â€” the Goodyear Electronic Differential Analyzer. GEDA uses voltages and wave forms to compute in an hour the most complex math problems that would take 500 man-hours or more, using slide rule methodsâ€”acts as an “electrical brain” that can solve any problem from trajectories of space rockets to improvement of workflow through factories.
The newest GEDA, Model L3, is smaller, more compact and easier to operate than other electronic computersâ€”occupies no more space than the average desk. After brief instruction, clerical workers are able to operate GEDA.
3 Important, New Electronic Digital Computers
For Engineering, Science and Business
Entirely new circuit designs have enabled CRC to produce a complete line of relatively small, low cost, highly reliable, digital electronic computers.
They may be purchased outright, or leased with the option to buy. A complete parts and service warranty, including both preventive and special maintenance will be included with lease if desired.
2 Computers? No-Just One
Leading design and research engineers have found that one IDA computer does the work of 2 ordinary computers â€” because of such ahead-of-the-field features as those outlined below:
Interchangeable Set-up Boards: permit problem change-over in minutes; thus IDA is always at work, there’s no lost set-up time!
20 Uncommitted Amplifiers: perform any computing function; and any required scale factor may be used for any number of inputs to any amplifier.
Hold Control: usually found only in most expensive computers, permits introduction of gross non-linearities.
8 Initial Conditions: once fixed, are automatically restored after each solution.
New Extra-Convenient Compactness: with the IDA you can actually sit at your desk while you compute!
Read for yourself the complete story on the truly advanced IDA computer. See how its twofold greater efficiency boosts your owa Just write for Catalog SA. Includes theory, set-up, typical examples.

THE NEW LOGRING
Digital Graph Plotter
THE LOGRING DIGITAL GRAPH PLOTTER automatic-
ally plots one variable against another algebraically in incremental steps, in response to electrical impulses. It is ideally adapted for use as a read-out device for electronic digital computers, especially digital differential analyzers, and for use in connection with such problems as aircraft tracking and automatic data reduction.
â€¢ plots at speeds up to 20 steps per second, in incremental steps of 1/64 of an inch.
â€¢ simultaneous movement on both axes in either direction.
â€¢ can be controlled electronically or by external or remote switches or relays.
â€¢ will make several carbon copies or duplicating stencil.
â€¢ instant manual positioning of pen and drum.
â€¢ takes 12″ x 18″ paper or continuous 12″ strip.
Mechanical simplicity ..high reliability ..digital accuracy ..quick pen cartridge change..self-contained power supply.

It seems to me that anyone who would use the phrase “Getting Closer to Infinity” does not really understand the concept of infinity.
GETTING CLOSER TO INFINITY
Businessmen, engineers, and scientists now are solving problems in scientific and industrial data processing which, a few short years ago, would have been considered well-nigh infinite.
IBM Electronic Business Machines are making an important contribution to this progress. These machines accomplish once-overwhelming tasks with incredible speed and accuracy … freeing thousands of valuable minds for creative effort.

You can delay that signal with an
ERA BOUNDARY-DISPLACEMENT MAGNETIC RECORDING DELAY LINE
FREQUENCY RANGEâ€”any five-octave band between 5 cps and 30,000cps, with appropriate drum speed.
DELAYâ€”up to 1000 wavelengths of information storage per channel; 200-second delay maximum at 5 cpsâ€”proportionately less with increase in frequency.
