Pre-Discovery Before the discovery of insulin‚ diabetes was a feared disease that most certainly led to death.

William Herschel was frustrated with the small telescopes he was using. He couldn’t afford larger telescopes‚ so he built one himself. He was observing a Nebula when he discovered Uranus. What questions were asked? How can he see it? What if

stand in sharp contrast to each other. The clerk and the squire are of similar ages but are very different. The clerk is a member of the middle class‚ has attended Oxford and studied Aristotle‚ while the squire‚ a member of the upper class‚ has been educated in the arts of chivalry. In appearance wise the clerk is a "grave" or somber individual. He is thin "hollow-cheeked" and dresses poorly ("outer cloak threadbare"). On the other hand the squire is a bright‚ cheerful person.

The Discovery of Neptune Neptune was discovered in September 1845. It was discovered by means of mathematics before being seen through a telescope. It began in 1843 when John Adams‚ a young English astronomer and mathematician‚ began working to find thew location of the unknown planet. Adams predicted the planned would be about 1.6 billion kilometres farther from the sun then Uranus. That’s when he completed his work in September 1845. Also Urbain Leverriar‚ unknown to Adams‚ began working

The Discovery Of The Electron The electron was discovered in 1895 by J.J. Thomson in the form of cathode rays‚ and was the first elementary particle to be identified. The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me <approximately equal> 9.1 x 10 -28 g‚ about 1/1836 of the mass of the proton or neutron. The charge of the electron is -e = -4.8 x 10^-10 esu <elec trostatic unit). The sign of the electron’s charge is negative by convention‚ and
