The Greatest Machine Never Built
mikejuk writes "John Graham-Cumming is the leading light behind a project to actually build the analytical engine dreamed of by Charles Babbage. There is a tendency to think that everything that Babbage thought up was little more than a calculating machine, but as the video makes 100% clear the analytical engine was a real computer that could run programs. From the article: 'Of course Ada Lovelace was the first programmer, but more importantly her work with Babbage took the analytical engine from the realms of mathematical table construction into the wider world of non-mathematical programming. Her notes indicate that had the machine been built there is no question that it would have been exploited just as we use silicon-based machines today.
To see the machine built and running programs would be the final proof that Babbage really did invent the general purpose computer in the age of the steam engine.'"

By whom? I have never heard the analytical engine described in terms like that.
A lot happened in the first part of the Victorian era in the UK - I am referencing the UK because (a) that's where Babbage was and (b) I know a little of the history. This was a period when blacksmith engineering was rapidly giving way to scientific engineering. In essence, just as now with silicon, engineering techniques were developing fast as a response to new requirements for precision and metallurgy. So "the technology of the time" would itself have been different if the Government of the day had grasped just what it had, and made a real push for it. I would go out on a limb and suggest that if Prince Albert hadn't died when he did, the Analytical Engine would probably have been built. He was a major proponent of technical development and ruffled a lot of Establishment (classically educated) figures, but his Great Exhibition was a huge success. He died in 1861, in his early 40s. Babbage in 1871.
From scarped cliff or quarried stone she cries "A thousand types are gone, I care for nothing, no not one."
That is because Samuel William Jefferson, who invented the computer and build one, also invented the time machine in 1827.
In 2079 his great-great-great-great-grandson, Hydro Jefferson, had an argument with his girlfriend about a cupcake (or a dancer called C-Cups. The books are unsure about that.)
She then went back in time and killed S.W. Jefferson as a little baby.
Don't fight for your country, if your country does not fight for you.
You are correct that I care about the PR side of things. I need to because I need to raise a substantial amount of money.
But it's far from all PR. There's now a registered British charity with a board of trustees and the pre-eminent Babbage expert, Doron Swade, who built the Difference Engine No. 2 at the Science Museum is running the technical side of the project.
Study of the digitized plans has been underway since February and some first results will be announced this summer. We actively want to build a 3D working model in a tool like Autodesk.
Thomas Fowler actually built a calculation machine in wood, presented to the Royal Society in 1840!!!!

This only fault was not to have the social background that Babbage had...
I quote from the front page of the site dedicated to him:
Fowler writes to Airy:
"I had the honor in May 1840 to submit the machine to the inspection of many Learned Men in London among whom were the Marquis of Northampton, Mr Babbage, W F Baily and A de Morgan Esq with many other Noblemen and Gentlemen, Fellows of the Royal Society etc and it would have been a great satisfaction to me if I could have had the advantage of your opinion also. They all spoke favourably of my invention but my greatest wish was to have had a thorough investigation of the whole principle of the machine and its details, as far as I could explain them, in a way very different from a popular exhibition:- this investigation I hope it will still have by some first rate men of science before it is be laid aside or adopted.
I am fully aware of tendency to overrate one's own inventions and to attach undue importance to subjects that preoccupy the mind but I venture to say and hope to be fully appreciated by a Gentleman of your scientific achievements, that I am often astonished at the beautiful aspect of a calculation entirely mechanical.
I often reflect that had the Ternary instead of the binary Notation been adopted in the Infancy of Society, machines something like the present would long ere this have been common, as the transition from mental to mechanical calculation would have been so very obvious and simple.
I am very sorry I cannot furnish you with any drawings of the Machine, but I hope I shall be able to exhibit it before the British Association at Devonport in August next, where I venture to hope and believe I may again be favoured with your invaluable assistance to bring it into notice. I have led a very retired life in this town without the advantages of any hints or assistance from any one and I should be lost amidst the crowd of learned and distinguished persons assembled at the meeting without some kind friend to take me by the hand and protect me."
Charles Babbage, Augustus De Morgan, George Airy and many other leading mathematicians of the day witnessed his machine in operation. These names have become beacons in the history of science yet nowhere will you find reference to Thomas Fowler. Airy asked that he produce plans of his machine but Fowler, recalling his experience with the Thermosiphon, refused to publish his design.
The machine was superior in many respects to Babbage's calculating machine, the Difference Engine, generally regarded as the first digital computer. Fowler's machine anticipated the modern computer in its design by using a ternary calculating method. This is in contrast to Babbage's machine which performed a decimal calculation, an approach which made his machine very complicated. The government of the day became increasingly disillusioned by the money they were having to pour into its development. So much so that the government refused to even look at Fowler's machine. Had Thomas Fowler published his design he would no doubt have won the support of many leading mathematicians of the time. Unfortunately, it took several decades before his approach was re-invented and in the mean time his name had slipped into obscurity.
