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.

SOLAR SYSTEM PLANETS MERCURY • The closest planet to the sun‚ Mercury is only a bit larger than Earth’s moon. Its day side is scorched by the sun and can reach 840 degrees Fahrenheit (450 Celsius)‚ but on the night side‚ temperatures drop to hundreds of degrees below freezing. VENUS • The second planet from the sun‚ Venus is terribly hot‚ even hotter than Mercury. The atmosphere is toxic. The pressure at the surface would crush and kill you. Scientists describe Venus’ situation as a runaway greenhouse

breakdown of Mercury’s crust. Mercury’s atmosphere is not stable and is constantly being refreshed because of its atoms escaping into space as a result of the planet’s heat. The earths atmosphere compared to mercury is much MUCH better in terms of protection. If we had the same atmosphere as mercury‚ we would all be dead. The heat‚ the radiation‚ and the sheer brightness of the sun‚ would be a fatal combination. Sources http://aura.gsfc.nasa.gov/%5C/o utreach/index.html http://www.scienceterrific.com/at

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.
