An essay has been defined in a variety of ways. One definition is a "prose composition with a focused subject of discussion" or a "long, systematic discourse". Aldous Huxleya leading essayist, gives guidance on the subject. Furthermore, Huxley argues that "essays belong to a literary species whose extreme variability can be studied most effectively within a three-poled frame of reference".
Then two major engineering innovations—resistance heating and small, efficient motors—led to electric stoves and irons, vacuum cleaners, washers, dryers, and dishwashers.
In the second half of the century advances in electronics yielded appliances that could be set on timers and even programmed, further reducing the domestic workload by allowing washing and cooking to go on without the presence of the human launderer or cook.
Engine-powered vacuum cleaner British civil engineer H. Cecil Booth patents a vacuum cleaner powered by an engine and mounted on a horse-drawn cart. Teams of operators would reel the hoses into buildings to be cleaned. Lightweight electric iron introduced Earl Richardson of Ontario, California, introduces the lightweight electric iron.
After complaints from customers that it overheated in the center, Richardson makes an iron with more heat in the point, useful for pressing around buttonholes and ruffles. Electric filaments improved Engineer Albert Marsh patents the nickel and chromium alloy nichrome, used to make electric filaments that can heat up quickly without burning out.
The advent of nichrome paves the way, 4 years later, for the first electric toaster. First practical domestic vacuum cleaner James Spangler, a janitor at an Ohio department store who suffers from asthma, invents his "electric suction-sweeper," the first practical domestic vacuum cleaner.
It employs an electric fan to generate suction, rotating brushes to loosen dirt, a pillowcase for a filter, and a broomstick for a handle.
This gives the vacuum cleaner more horsepower, higher airflow and suction, better engine cooling, and more portability than was possible with the larger, heavier induction motor.
And the rest, as they say, is history. First commercially successful electric toaster Frank Shailor of General Electric files a patent application for the D, the first commercially successful electric toaster.
The D has a single heating element and no exterior casing. It has no working parts, no controls, and no sensors; a slice of bread must be turned by hand to toast on both sides.
First refrigerator for home use Fred W. Wolf of Fort Wayne, Indiana, invents the first refrigerator for home use, a small unit mounted on top of an old-fashioned icebox and requiring external plumbing connections.
Only in would a hermetically sealed standalone home refrigerator of the modern type, based on pre work by Marcel Audiffren of France and by self-trained machinist Christian Steenstrup of Schenectady, New York, be commercially introduced.
This and other early models use toxic gases such as methyl chloride and sulfur dioxide as refrigerants. On units not hermetically sealed, leaks—and resulting explosions and poisonings—are not uncommon, but the gas danger ends in with the advent of Freon-operated compressor refrigerators for home kitchens.
First electric dishwasher on the market The Walker brothers of Philadelphia produce the first electric dishwasher to go on the market, with full-scale commercialization by Hotpoint and others in Calrod developed Charles C.
Abbot of General Electric develops an electrically insulating, heat conducting ceramic "Calrod" that is still used in many electrical household appliances as well as in industry. The invention finally reaches the marketplace in under the name Toastmaster.
First iron with an adjustable temperature control The Silex Company introduces the first iron with an adjustable temperature control. The thermostat, devised by Joseph Myers, is made of pure silver. First garbage disposal John W. Hammes, a Racine, Wisconsin, architect, develops the first garbage disposal in his basement because he wants to make kitchen cleanup work easier for his wife.
Nicknamed the "electric pig" when first introduced by the Emerson Electric Company, the appliance operates on the principle of centrifugal force to pulverize food waste against a stationary grind ring so it would easily flush down the drain.
Washing machine to wash, rinse, and extract water from clothes John W.
Chamberlain of Bendix Corporation invents a device that enables a washing machine to wash, rinse, and extract water from clothes in a single operation. This eliminates the need for cumbersome and often dangerous powered wringer rolls atop the machine.

Toby Young. The Fall of the Meritocracy. The left loathes the concept of IQ -- especially the claim that it helps to determine socio-economic status, rather than vice versa-- because of a near-religious attachment to the idea that man is a piece of clay that can be moulded into any shape by society.
