Microwave Ovens

My topic of this paper is going to be microwaves and the effects that they have had
on technology in the past and in today. My proof of this is the technology existing right
now using microwaves. Such as: satellites, microwave ovens, radar, radio, and television.
The microwave and the discovery of microwaves ushered in a new for us. A example of
microwaves helping us would be Courtney�s example, �When cooked for the correct
amount of time meats and veggies prepared in a microwave oven tend to retain more of
their natural juices then foods cooked other ways�. With the discovery of microwaves we
were able to communicate much easier. Better communications technology had assisted us
in many occasion. One occasion would be in wars. Soldiers could communicate between
each other using radios and satellites. With soldiers easily contacting each other, attacks
such as ambushes were able to be possible without even talking to the other attack team.
Another example of microwave technology is the fact that when companies branch,
sometimes they can set up offices even across the world! Without satellites there would be
no way one office of the company could talk to the other without using the postal service
but that could be very expensive and the note could get easily lost causing the company to
possibly lose a lot of money.
Before microwaves, there were just regular ovens (The ovens were either gas or
electric or some sort of heating device made by a primitive culture). Primitive people
generally bake or roasted by covering their food with hot ashes, earth, or heated rocks.
Archaeologists have even discovered in the caves of the Swiss lake region the leftover
petrified remains of bread made from coarse grain, and have guessed that the Stone Age
bakers had placed their loaves on hot rocks and covered them with ashes. Such crude
roasting represents an advance over the most primitive cooking of any kind, which
consists of direct broiling on a stick or grid of sticks. In Egypt the earliest form of oven
that they had consisted of two to three vertical stones supporting flat stones. By about
2500 BC the Egyptians used brick furnaces in the kitchens of the larger estates, and by
about 2000 BC they had devised a clay oven with a grate. In Mesopotamia, the temple
kitchens of Ur had large clay beehive bread ovens and clay cooking ranges with flat tops
and circular flues. The Terra-cotta models that had been found in Greece seemed to
indicate that women baked bread by building a clay oven like a huge bowl, burning grass
and sticks inside and around it, and after the fire died down placing the loaves inside of it.
Remains found from the Roman period of time and the Middle Age period of times seem
to indicate the use of ovens like those still in use on the Gaspe Peninsula and in other parts
of the world that have retained a semipeasent economy. These ovens consist of a simple
masonry chamber above a firebox. As for colonial America cooking was done in alcoves
built into the masonry backs of the wide kitchen fireplaces, or in completely enclosed
Dutch ovens. In cities, bakers often placed their ovens underground, to maintain heat
more effectively. In the early 1700�s the New York City Common Council granted a
number of permits for building such ovens under the road before the bakery. In the later
parts of the 18th century metal ovens and cooking ranges appeared in both Europe and the
United States. The first metal ovens were tin boxes for use in fireplaces. The first kitchen
ranges containing ovens were undoubtedly influenced by the �Salisbury Kitchen� and
other galley stoves for ships, which were preferred because they could be used for
roasting, boiling and baking all in one amount of time. No basic changes in ovens had been
made until the early 1890�s, when gas was becoming far popular for cooking. In the
1930�s electric ovens had been made with thermostats and automatic timers were
introduced. These could be turned on and off automatically at a predetermined time
selected by...
