The E6-B Flight Computer Is 75 Years Old, Still In Use (informationweek.com)
An anonymous reader writes: Few devices have been around this long, have had cameo appearances in Star Trek, and remain in use today. The current E6-B looks almost exactly the same as the first one manufactured 75 years ago. It was designed by U.S. Naval Lt. Philip Dalton in the late 1930s. When he completed the final version, it was introduced to the Army in 1940, and later used widely during WWII. Today is a required instrument for flight training, and has appeared on Star Trek original series several times, as Mr. Spock used a E6-B for critical calculations.
"Windows 95 is 20 years old, and is still in use today."
That doesn't quite have the same ring to it, does it?
I remember being 14 and learning to use an E6-B flight computer for the first time. It's pretty amazing to be able to sit down and develop a to-the-minute flight plan from departure to arrival and then be able to go out and execute that plan. Flying along hitting all your waypoints at the proper time, getting your enroute crab angle correct for the given winds aloft and not killing yourself along the way was always exciting. Hats off to Lt. Dalton. Your invention will always have a place in my flight bag.
I was musing just the other day about a related calculating method that has fallen into disuse, the nomogram. Nomograms always impressed me as an especially clever way to perform specific mathematical tasks.
When I was young, and dirt was still sparkling and shiny new, nomograms were in every engineering textbook, handbook, and reference book. Their demise in engineering applications seems to have come with a whimper, not a bang, as no one seems to have noticed it.
its a stupid slide rule with a stupid carnival wheel attachment.
A computer is a device that can compute. The E6-B qualifies.
Modern usage has co-opted the term to refer to an electronic device that computes. But computers pre-date the electronic age.

A computer is a device that can compute...
Using that definition my hand is a computer also...
Only if it's connected to a brain.

You could be. Computer used to be a job title.
We hope your rules and wisdom choke you / Now we are one in everlasting peace
The E6B is a rite of passage for all student pilots, but I haven't found anyone that kept using it. An electronics calculator from the 70s is much faster and easier to use in a cockpit, but despite not being part of the practical test, every designated pilot examiner wants to see every student use one, because they used one as a student.

When Alan Turing did his seminal work on computing and computability, he used "computer" to mean both a human with a pencil and paper and abstract mechanical devices generalizing and simplifying what this human computer did.
I'm with Turning on this. A "computer" is any system that computes, whether it is entirely made out of live meat, made out of meat plus mechanical, electrical, and/or electronic aids, or made purely of such aids. The term may also be applied to aids that require a made-of-meat operator (or mechanical simulation of one) in the absence of the operator.
By this definition, both slide rule s and nomogaphs qualify as "computers".
