  • The Difference Engine was an accurate mechanical calculator designed by Charles Babbage in the 1840s, but was never built in its inventor's lifetime. Here, its modern builder explains how it works.

    Some engineering history facts: the major factor that stopped Babbage realizing the machine was in large part, lack of precision engineering standards at the time. There were no standard screw threads nor standardized drill sizes. Joseph Clement, the brilliant machinist who actually did the building - and drafting - for Babbage - recognised this, but it was his student, Joseph Whitworth, who achieved this goal - and was knighted for it, it wa of such economic importance. Hence, until adopting metric, British threads were called Whitworth, or BSW - British Standard Whitworth,

Just proves my long standing theory that humanity has not only been behind by 10-20 years at any given time, but is a solid 2 centuries behind where we could have been...If only things had been slightly different, and Babbage had gotten the full funding he needed in the 1820s-1830s.

    It is what computer science calls "Turing-Complete", so if you built a version the size of a small country, and devise some sort of mechanical screen, and a compiler to output Babbage camshaft designs, yes, you could run portal, at 1 frame per year or something.

    You only need one difference engine to produce a tabulated book of results which can then be copied as many times as needed. Considering the amount of time that would have been spent in those days trying to calculate the same problems (BY HAND I might add) this would be well worth it because of the time saved and the inherent accuracy in the results which reduce errors.

    Babbage created the class definition for the difference engine But he defined an abstract class, which could not be instantiated until someone overrode his definition with a superclass containing methods for creating precise mechanical parts. The superclass still needed to be instantiated on a platform that could execute the constructor without throwing an InsufficientFunding exception

    Digital doesn't mean 'uses electricity'. Electric things can be analog (like a tube radio) or digital, and so can mechanical things. Digital means it operates on discrete numbers, like 1, 2, 3, ..., while analog means it operates on a continuous range (think a mechanical kitchen timer, where you can turn the dial to any point, not just x minutes y seconds).

If Babbage had gone the route, could he have had his Difference Engine built by the folks who made pipe organs?

    If the analytical engine could be built of nanoscale parts, and cranked as fast as it would go w/o tearing apart, you might get speeds comparable to today's desktops. I think. I'm just kind of bubbling with possibilities right now, and won't pretend to know for sure.

  • @LaurenceStant

    clock freq. is measured in Hertz, which is cycles per second.4 cycles per calc., I imagine it would take about 2 seconds to turn the handle and its 1 cyc per turn : 2 x 4 = 8Hz = 0.000008Mhz
    "RAM" wise it wud only have enough to contain the 31 digits required plus any carry bits - too tired to work out but it would be no more than 62 digits. As 1 digit is 1 bit then u have at most 62 bits which is nearly 64 bits which is nearly 8 bytes (8 bits in a byte). This is just under 0.00006MB.

      +Eltodofull2 this is a fully mechanical machine that came up in 1786, somewhere we just entered steam machine era. but this is powered by hand. on the other hand, Alan Turing's computer was 150 years ahead of it. I went to this museum twice and one time there was a guy demonstrating how to use it to calculate deferential equation. seeing all those hundreds thousands of gear moving is absolutely amazing. goose bumps all over the place.

    Well, if you crank the handle at 1 revolution per second, this device is would be operating at 1 Hz. -which is about 18billion times slower than the minimum system requirements for Crysis (1.8GHz). Perhaps if you had Superman at the crank, but then the cogs and gears would obliterated by the frictional and centrifical forces generated.
    In short, Crysis would crash this machine like no other computer has ever been crashed!
