Difference engines are strictly calculators. They crunch numbers the only way they know how - by repeated addition according to the method of finite differences. They cannot be used for general arithmetical calculation. The Analytical Engine is much more than a calculator and marks the progression from the mechanized arithmetic of calculation to fully-fledged general-purpose computation.

Physical Legacy Aside from a few partially complete mechanical assemblies and test models of small working sections, none of Babbage's designs was physically realized in its entirety in his lifetime. The major assembly he did complete was one-seventh of Difference Engine No. 1, a demonstration piece consisting of about 2,000 parts assembled in 1832. This works impeccably to this day and is the first successful automatic calculating device to embody mathematical rule in mechanism. A small experimental piece of the Analytical Engine was under construction at the time of Babbage's death in 1871. Many of the small experimental assemblies survived, as does a comprehensive archive of his drawings and notebooks. The designs for Babbage's vast mechanical computing engines rank as one of the startling intellectual achievements of the 19th century. It is only in recent decades that his work has been studied in detail and that the extent of what he accomplished becomes increasingly evident.

the Jacquard loom used a system of hooks and needles to lift the appropriate warp threads. The pattern was stored on a collection of thick paper cards perforated with rectangular holes. As the fabric was woven, the hooks were held stationary by the surface of the card. However, whenever a hole was encountered, a hook would be allowed to pass through to lift its thread. By stringing together a large number of cards, an intricate pattern could be created.

Speaking of civility on a personal level, Elder Robert D. Hales of the Quorum of the Twelve Apostles taught Latter-day Saints how to respond to criticism: “Some people mistakenly think responses such as silence, meekness, forgiveness, and bearing humble testimony are passive or weak. But, to ‘love [our] enemies, bless them that curse [us], do good to them that hate [us], and pray for them which despitefully use [us], and persecute [us]’ (Matthew 5:44) takes faith, strength, and, most of all, Christian courage.”
