John Wilkins: Wilkins gave Boyle much of his education which helped create his interest‚ and inspiration. In 1662‚ Boyle did an expirement involving a J Shaped tube‚ oxygen‚ and mercury. He put different amounts of mercury in each tube‚ which caused a change in pressure. No matter how much or little mercury in the tube‚ the volume times the pressure remained the same. This lead to Boyle’s law‚ stating that Pressure*Volume = K‚ where K is a constant and the temperature is constant.

He was in one of the first groups of astronauts. It was called the “Mercury Seven”. It was called that because it was seven men on the Mercury spacecraft. The first thing that John Glenn did that went down into history was‚ he was the first American to ever orbit the Earth. At that time two Americans had already been sent into space but none of them had orbited the Earth. The “Mercury Seven” launched on February 20‚ 1962. John Glenn renamed the group of astronauts to “Friendship

Immunizations have been debated for decades. The most controversial vaccination is the MMR‚ Measles‚ Mumps and Rubella; it is given to children from 12 months to 12 years old. In the 1930s Thimerosal a mercury-containing organic compound was introduced to the vaccines as a preservative.

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source
