The Antikythera Mechanism was discovered on May 17th 1902, by archaeologist Valerios Stais when he was diving on the Antikythera wreck off Point Glyphadia on the Greek island of Antikythera. The wreck is believed to have sunk in the 1st century BCE and has yielded many spectacular artifacts. The most mysterious of these is the Antikythera mechanism, a solid lump of corroded bronze gears. It has taken over a century, the latest imaging technology, and decades of research from a few dedicated scholars of mechanical engineering to piece together what the mechanism did.
I put together this playlist of short youtube videos. Together they describe the latest advances in understanding the mechanism and how it worked. There are four videos that take about 20 minutes to watch. Just click on the video and all four will play.
Charles Babbage and Howard Aiken. How the Analytical Engine influenced the IBM Automatic Sequence Controlled Calculator aka The Harvard Mk I
In 1936, [Howard] Aiken had proposed his idea [to build a giant calculating machine] to the [Harvard University] Physics Department, … He was told by the chairman, Frederick Saunders, that a lab technician, Carmelo Lanza, had told him about a similar contraption already stored up in the Science Center attic.
Intrigued, Aiken had Lanza lead him to the machine, which turned out to be a set of brass wheels from English mathematician and philosopher Charles Babbage’s unfinished “analytical engine” from nearly 100 years earlier.
Aiken immediately recognized that he and Babbage had the same mechanism in mind. Fortunately for Aiken, where lack of money and poor materials had left Babbage’s dream incomplete, he would have much more success
Later, those brass wheels, along with a set of books that had been given to him by the grandson of Babbage, would occupy a prominent spot in Aiken’s office. In an interview with I. Bernard Cohen ’37, PhD ’47, Victor S. Thomas Professor of the History of Science Emeritus, Aiken pointed to Babbage’s books and said, “There’s my education in computers, right there; this is the whole thing, everything I took out of a book.”

The Liverpool Street Station in Manchester, England is now part of The museum of Science and Technology. The Station was built in 1830 and is the oldest railway station in the world. On the opposite side of the tracks to the ticketing hall is the world’s first railway warehouse. In this building is a working replica of the worlds first stored program computer, Baby, the Manchester Mk I Prototype.
Finding an authoritative history of the Computer’s invention is almost impossible. There are several reasons for this problem: People disagree on the meaning of the word “invent”, they also disagree on the meaning of the word “computer”. Finally significant parts of the history were either lost or deliberately concealed and only came to light again in the 1960′s and 70′s. The United States Army was the first organization to stake a claim to the invention of the computer with the 1946 public announcement of the ENIAC (Electronic Numerical Integrator and Computer). It has since become commonly accepted that ENIAC was the worlds first computer when in fact it was not a computer, in the modern sense, at all, and was not even the first of its class.
I ‘ve been trying to understand what it means to invent something and found this site very useful Wright Brothers History: The Tale of the Airplane A Brief Account of the Invention of the Airplane researched, written, and designed by Gary Bradshaw.
This graph really sums it up. You don’t have to be first but you do have to change the Paradigm.
I just watched Lawrence Lessig‘s speech, Free Culturefor a second time. The recording below was made at the O’Reilly Open Source Convention 2002 where Lessig delivered the keynote. It is a superb example of a well designed and delivered power point presentation. It is also very persuasive.
Augusta Ada, Countess of Lovelace (1815 to 1852), also known as Ada Lovelace, was the only legitimate daughter of the poet Lord Byron. Raised by her mother she was given private instruction in mathematics and sciences, When she was 17 she met Charles Babbage at a party and became interested in his work on The Analytical Engine, At the suggestion of Charles Wheatstone she translated a French description of the Analytical Engine “Notions sur la machine analytique” by the Italian Engineer Luigi Menabrea. This document was based on some lectures Babbage had delivered in Turin some years earlier. After reading Ada’s translation Babbage suggested she add some notes of her own since she was “intimately acquainted” with the subject. This she did and published her Sketch of the Analytical Engine in 1843. Continue reading
