Fusion: Our Future's Energy?
<view this essay>.... Uranium that do not exist in nature). They discovered that the nucleus of Uranium-235 breaks apart into two smaller nuclei after absorbing a neutron. This happens because the extra neutron made it unstable. This produces more neutrons that bombard more Uranium nuclei, causing a chain reaction that produces an enormous amount of energy.
The problem is the nuclear waste that is produces. It is very radioactive and will not become stable for a very long time. Such a harmful substance is a great health concern and needs to be disposed of. Another problem is the energy it needs. It uses an element that is hard to find and which will eventually run out. Al .....

that matter, the only reason for the existence of insurance

Gas Laws (cemistry)
<view this essay>.... measurements on gases were first made in a rational manner by the English chemist Robert Boyle (1627 - 1691). The instruments used by Boyle to measure pressure were two: the manometer, which measures differences in pressure, and the barometer, which measures the total pressure of the atmosphere.
A manometer is simply a bent piece of tubing, preferably glass with one end closed.
When the liquid level in both arms is the same, the pressure of the sample of gas inside the closed end must equal the pressure of the external atmosphere since the downward force on the two columns of liquid is then equal. When the liquid levels are unequal, the .....
