question: CHAPTER 6 

Can piety the discord heal, Or stanch the death-feud's enmity? --Scott 

It must not be supposed that such a history of Guy's mind was expressed by himself, or understood by Mrs. Edmonstone; but she saw enough to guess at his character, perceive the sort of guidance he needed, and be doubly interested in him. Much did she wish he could have such a friend as her brother would have been, and hope that nothing would prevent a friendship with her nephew. 

The present question about the horse was, she thought, unfortunate, since, though Guy had exercised great self-denial, it was no wonder Philip was annoyed. Mr. Edmonstone's vexation was soon over. As soon as she had persuaded him that there had been no offence, he strove to say with a good grace, that it was very proper, and told Guy he would be a thorough book-worm and tremendous scholar, which Guy took as an excellent joke. 

Philip had made up his mind to be forbearing, and to say no more about it. Laura thought this a pity, as they could thus never come to an understanding; but when she hinted it, he wore such a dignified air of not being offended, that she was much ashamed of having tried to direct one so much better able to judge. On his side Guy had no idea the trouble he had caused; so, after bestowing his thanks in a gay, off-hand way, which Philip thought the worst feature of the case, he did his best to bring Hecuba back into his mind, drive the hunters out of it, and appease the much-aggrieved William of Deloraine.

question: Orville Wright was born on August 19, 1871 in Dayton, Ohio, USA and died on January 30, 1948. Together with his brother, Wilbur, he was the first airplane builder. The brothers created the first controlled, powered and heavier-than-air human flight. 

His parents were Milton Wright and Susan Catherine Koerner and besides the two famous brothers they had five children. One day after a trip his father brought as a gift a small helicopter. The kids loved it and as they played daily with it after a while it broke. The brothers managed to create a new one. Wright even let go his plans of attending Yale. He spent his time helping his ill mother and reading in his father's library. 

In 1884 the family decided to move to Dayton and they remained there until the 1870's. A printing press was built by the two and Wilbur was an editor. In 1892 they started being fascinated by the aeronautical events of that time. Then they started to create an airplane and Wilbur was considered the head of the team. They were the inventors of "three axis-control", which permitted the pilot to _ the aircraft's balance. 

In 1900 they had their first attempts to make a functional glider -- of course it didn't have a pilot. After three years they thought of introducing an engine to the glider. At first, their patent application was refused in 1903, but after one year it was accepted. 

Orville's first flight lasted 12 seconds and had 36.5 meters. He was responsible with the public shows near Washington in the United States. On September 9, 1908 his flight was 62 minutes and 15 seconds long and the success was huge.

question: Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. While the metal itself is radioactive, its high density makes it more effective than lead in halting radiation from strong sources such as radium. Other uses of depleted uranium include counterweights for aircraft control surfaces, as ballast for missile re-entry vehicles and as a shielding material. Due to its high density, this material is found in inertial guidance systems and in gyroscopic compasses. Depleted uranium is preferred over similarly dense metals due to its ability to be easily machined and cast as well as its relatively low cost. The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity (uranium being only a weak alpha emitter). 

The discovery and isolation of radium in uranium ore (pitchblende) by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials. This left a prodigious quantity of uranium as a waste product, since it takes three tonnes of uranium to extract one gram of radium. This waste product was diverted to the glazing industry, making uranium glazes very inexpensive and abundant. Besides the pottery glazes, uranium tile glazes accounted for the bulk of the use, including common bathroom and kitchen tiles which can be produced in green, yellow, mauve, black, blue, red and other colors.
