Humphry Davy and the Davy lamp

Humphry Davy was a british chemist and inventor. He started to experiment with lamps and soon he is a safety lamp with a wick and oil vessel burning originally a heavy vegetable oil, devised in 1815 by Sir Humphry Davy. It was created for use in coal mines, allowing deep seams to be mined despite the presence of methane and other flammablegases, called firedamp or minedamp. Davy had discovered that a flame enclosed inside a mesh of a certain fineness cannot ignite firedamp. The screen acts as a flame arrestor; air (and any firedamp present) can pass through the mesh freely enough to support combustion, but the holes are too fine to allow a flame to propagate through them and ignite any firedamp outside the mesh. The first trial of a Davy lamp with a wire sieve was at Hebburn Colliery on 9 January 1816.

Comparing The Painting "Christina's World" by Andrew Wyeth with the short story "The Story of an Hour"

In the picture we see a girl crawling trough the grass, trying to reach a house or a farm witha sort of handicap. This demonstrate hopelessness which I get the sense that Mrs Mallars in "The Story of an Hour" is having too. She wants to be free from her husband and if we compare Mrs. Mallard with the girl in the painting we can see that they both are kind of trapped. I also think the mood in the painting is quite similar to the mood in the short story but at the same time i don't think it fit that much. The girl in the painting has obvious some physical damages of some kind of sort, but the girl in the story feels trapped because she can't leave her husband.

So in many ways the painting and the story has some similarities, but not in everything.
