Early twentieth-century experiments on the physics of very small-scale phenomena led to the discovery of phenomena which could not be predicted on the basis of classical physics, and to the development of new models ( theories ) that described and predicted very accurately these micro-scale phenomena.

Early PDP-8 models used a front panel interface, a paper-tape reader and a teletype printer with an optional paper-tape punch.

Early models of the PDP-11 had no dedicated bus for input / output, but only a memory bus called the Unibus, as input and output devices were mapped to memory addresses.

Early models featured a pioneering form of variable valve timing in an attempt to give greater control, but this caused the valves to burn and therefore it was abandoned.

Early models feature motherboards and power supplies with the A300 designation.

Basch postulates that the boat “ cannot have been propelled by more than four oarsmen … so it can hardly be other than a fishing boat .” As opposed to other Early Bronze Age ship and boat models, this model was not found in a burial context.

Early providers of voice over IP services offered business models ( and technical solutions ) that mirrored the architecture of the legacy telephone network.

; Acoustic tablets: Early models were described as spark tablets — a small sound generator was mounted in the stylus, and the acoustic signal picked up by two microphones placed near the writing surface.

Early type brake shoes contained asbestos.

Early printings of this dictionary contained the famous dord.

Early almanacs therefore contained general horoscopes, as well as the more concrete information.

Several critics have pointed to grammatical errors in the Early Modern English style of the Book of Mormon and made the argument that because the first edition of the Book of Mormon contained hundreds of grammatical errors ( removed in later editions ), the book was therefore fabricated by J. Smith and not divinely inspired.
