Why was the wooden door invented?

The purpose of a door opening is: to allow people, animals and objects to pass for ventilation The purpose of a door closure is: preventing passage of infiltration air; reducing air drafts and creating an enclosed space that can be heated or cooled more effectively (revolving doors are especially efficient for this purpose) privacy, and noise reduction keeping occupants inside a vehicle regulation of access, especially when combined with various types of locks for aesthetics (e.g. cupboard doors cutting off view of the contents) to help prevent the spread of fire. The earliest records are those represented in the paintings of the Egyptian tombs, in which they are shown as single or double doors, each in a single piece of wood. In Egypt, where the climate is intensely dry, there would be no fear of their warping, but in other countries it would be necessary to frame them, which according to Vitruvius (iv. 6.) was done with stiles (sea/si) and rails (see: Frame and panel): the spaces enclosed being filled with panels (tympana) let into grooves made in the stiles and rails. The stiles were the vertical boards, one of which, tenoned or hinged, is known as the hanging stile, the other as the middle or meeting stile. The horizontal cross pieces are the top rail, bottom rail, and middle or intermediate rails. The most ancient doors were in timber, those made for King Solomon's temple being in olive wood (I Kings vi. 31-35), which were carved and overlaid with gold. The doors dwelt upon in Homer would appear to have been cased in silver or brass. Besides Olive wood, elm, cedar, oak and cypress were used.

There's a Northern England expression: 'Put th'wood in th'ole'. If you weren't going to use wood for a door, what could you use? Fabric or bead curtains are too draughty and not very intruder proof. Leather curtains hang without too much wind movement, but are not much better than fabric otherwise. Large stones are too heavy for everyday use, although fine for tombs. And cows tend to wander off, and there's a large gap below the udder level for draughts to pass through. Dec 15 06, 4:30 AM

Who invented the revolving door? On TV I saw a Parliment ceremony where a person aproaches a big wooden door only to have this door slammed in his face. I understand that this is a ceremony...but still, don't you Brits think that this is a bit rude? Who invented the common 'carbon rod down the center of a hexagonal wooden tube' pencil and in what year? A door and the metal doorknob on it are obviously at the same room temperature. Yet the doorknob feels colder to the touch than the door. Why? Who invented the zipper and why?
