Migraines are a specific headache caused by changes in the blood vessels that supply the brain.

Fire had many disadvantages, one was that fire depended on fuel and needed proper conditions to operate (no rain, minimal wind). Another disadvantage is that fire, if not handled properly, could result in a brush fire or even burn down their shelter. An advantage was it was efficient when conditions were correct. It provided an inexpensive form of lighting, and could be used for cooking and heating. Due to the persistent problem of limited fuel, inhabitants looked for a way to prolong the fuel.

.... system headed by Captain Robert Fitzroy. Captain Fitzroy would send ships around Britain to warn people of storms and such. However, he was often wrong and criticized and therefor committed suicide. Since then there have been many other services, but the largest one currently is the National Weather Service. The National Weather Service gives predictions for all of the world through satellite imagery for all countries.

On June 24th, 1947 while searching for the remains of a downed Marine C-46 transport, lost somewhere in the Mount Ranier area, a young Idahoan businessman named Kenneth Arnold spotted something that would change his life forever.

.... is the application of technology for the purpose of influencing the global properties of a planet. The sphere of influence should incorporate the alteration of the planet's environment to the extent that it will facilitate human existence on that planet. In order to accomplish this, technology must be aimed at three specific, vital areas: The creation of an aquatic medium, a terrestrial plateau and celestial ether that is conducive to human respiration. There are two planets from which to choose: Mars and Venus. Martyn J. Fogg authored what is regarded as a textbook of the future called Terraforming: Engineering Planetary Environments. I have chosen Fogg's bo .....
