What about all the other wars in American history? Many of the Indian Wars lasted decades, says Don Surber in the Charleston, W.V., Daily Mail. The Second Seminole War lasted from 1835 until 1842, and the Sioux Wars lasted from 1854 to 1890. Also, he says, in the case of Afghanistan our enemy struck first.
Special relativity is perhaps one of the least intuitive theories ever conceived in the history of science, yet it is central to physics. In E = mc 2 Einstein concluded that mass (m) and kinetic energy (E) are equal, since the speed of light (c 2) is constant. In other words, mass can be changed into energy, and energy can be changed into mass.
There are two equations concerning light that are usually taught in high school. Typically, both are taught without any derivation as to why they are the way they are. That is what I will do in the following. Equation Number Two: E = hÎ½.
