The London Science Museum's difference engine, the first one actually built from Babbage's design. The design has the same precision on all columns, but in calculating polynomials, the precision on the higher-order columns could be lower. A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.
The first implementation of the Atkinson cycle was in 1882; unlike later versions, it was arranged as an opposed-piston engine, the Atkinson differential engine. [6] [7] In this, a single crankshaft was connected to two opposed pistons through a toggle-jointed linkage that had a nonlinearity; for half a revolution, one piston remained almost stationary while the other approached it and ...
Adding machine by Johann Helfrich von Müller, 1784, in the Hessisches Landesmuseum Darmstadt. Johann Helfrich von Müller (January 16, 1746 in Kleve – 1830) was an engineer in the Hessian army who conceived the difference engine in 1786 (first written reference to the basic principles of a difference machine is dated to 1784), an idea that later evolved into modern computers.
A spur-gear differential has an equal-sized spur gears at each end, each of which is connected to an output shaft. [8] The input torque (i.e. from the engine or transmission) is applied to the differential via the rotating carrier. [8] Pinion pairs are located within the carrier and rotate freely on pins supported by the carrier.
Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.
