ʺThe big economic difference between nuclear and fossil‐fuelled power stations is that nuclear

reactors are more expensive to build and decommission, but cheaper to sun. So disputes over

the relative efficiency of the two systems revolve not just around prices of coal and uranium

today and tomorrow, but also around the way in which future income should be compared

with current income.ʺ

ʺAt any given moment we are being bombarded by physical and psychological stimuli

competing for our attention. Although our eyes are capable of handling more than 5 million

bits of data per second, our brain are capable of interpreting only about 500 bits per second.

With similar disparities between each of the other senses and the brain, it is easy to see that

we must select the visual, auditory, or tactile stimuli that we wish to compute at any specific

time.ʺ
