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.
In fact, Einstein stipulates in his list of conditions, printed in Isaacson's book (via website listsofnote.com), that she must not expect Einstein to either sit with her, or accompany her outside of the house - and she must stop talking when he requests.
