Dale,

- All I can come up with is that whenever I hear the term I find it
disturbing - perhaps it's my experience with the biological association.
- Come to think of it, some of us would be in physics because we just could
not deal with biology and dissections, similarly, many individuals who go to
medical school and find themselves unable to deal with the human body just
become psychiatrists, who generally should, but generally do not, examine
the body to check for physical causes of psychiatric symptoms.
- Language changes over 100's of years.

But, thanks for the facts.

Bill

Bill,

Why not call it that. It is just like the frogs and worms only better.
You charge the capacitor and then take it apart and look at the inards.
Then you put it back together and "presto" it comes back to life.
Besides, there is that 200 years of historical designation to overcome.

Later,
Dale
