I can buy a big telescope and pretend to be astronomer but the
telescope as such can't make astronomer from me. Well by
comparison with whatever miscroscope ...Consider all those
styli shapes. After loking at, say, 3 kinds one can't remember
either except the old ''trusted'' oval kind.
So the answer depends from our belief. Belief in the honesty of
our retipper as well in his capability to judge the gradations
of wear . The problem is that they can charge 500 euro for a
simple retip by which the cantilever/stylus combo is glued on
the tube rest of the old cantilever. According to Andreoli who
learned the trade by Aussie brothers he was able to do this job
in 5 minute time.
Fermi has stated: ''If I was smarter I could remember more of
those particles than I actually do''.
