Re: Capacitor charge, were is it?
Hi all,
I know this somewhat diverging from the business at hand but
I did want to inject a couple of thoughts to Greg's excellent post:

I have always wondered why the controversy about electrons not
spiralling into the nucleus. The question I've always asked myself is
"why should they?"

I think not only that, but there is a speed limit n'est pas?
