The big economic difference between nuclear and fossil fueled power stations is that the nuclear reactors are more expensive to build and decommission, but cheaper to run. So disputes over relatively of the two systems revolved not just around the prizes of coal and uranium today and tomorrow, but also around the way in which the future income should be compared with income.

At any given moment are being bombarded by physical and psychological stimuli computing for one attention. Although our eyes are capable of handling more than 5 millions of data per sec, our brains are capable of interpreting only about 500 bits per sec. with similar disparities between other senses and brain it is easy to see that select visual, auditory or tactile stimuli that we wish to compute at any specific time.
10.physical stimuli usually win the competition for our attention.
A B C
11.the capacity of human brain is sufficient to interpret nearly all the stimuli the senses can register under optimum condition.
