16 Copyright is a treasure for the pedant. It is also
doomed, according to some who should know. It is,
of course, computers which pose a serious threat to
the very notion of copyright. The problem is bad

can be copied in a few minutes. How many
computer users reading this can honestly say that
every program they use is fully paid for? It's about to
get very much worse, and seriously to affect those

Scientists have scant idea of why we sleep, and
find dreaming an even bigger mystery. Theories
range from the brain clearing its memory of junk
to the liberation of suppressed subconscious
urges. The reason for their Ignorance lies in the
astonishing design of the brain. The most
complex known object in the universe, it contains
as many nerve cells - neurons - as there are
stars in the Milky Way; about 100 billion of them.
Each communicates with thousands of its
neighbours, generating an unimaginable chatter.
18 Sustain ability in the use of soils does not mean avoiding all changes, or
trying to restore damaged soils to some pristine state. But it implies that

than these can be replenished by natural processes or human
intervention. We must be careful not to cause lasting damage to the
natural resilience of soils, about which we have little understanding.
